For IT Equipment in Canada, ICES-003 Issue 5 Required by August 2013

by admin on Sep.05, 2012, under Canada, EMC

For manufacturers of IT Equipment (ITE) selling in Canada, ICES-003 Issue 5 Information Technology Equipment (ITE) – Limits and Methods of Measurement was published last month by Industry Canada. 

Until August 31, 2013, both Issue 4 and Issue 5 will be accepted.  After that date, only Issue 5 will be accepted.

Existing models in compliance with previous versions of ICES-003 shall remain compliant under requirements of that previous issue, or may adopt the requirements in Issue 5.

There are major changes to the technical requirements in Issue 5.  Following is a summary. 

Reference Standards
Issue 5 references both CISPR22 and ANSI C63.4.  There are different routes of compliance that can be chosen, but once a route is chosen (eg. CISPR22 path or ANSI C63.4 path), that same route must be used to achieve compliance in all requirements. 

Below 1GHz has three routes:

  • Comply with the conducted/radiated emissions limits of CISPR22, while adhering to CISPR22 measurement methods
  • Comply with the conducted/radiated emissions limits listed in ICES-003 Issue 5 while adhering to ANSI C63.4 methods
  • Comply with conducted emissions limits listed in ICES-003 Issue 5, radiated emissions limits of CISPR22, while adhering to ANSI C63.4 methods

Above 1GHz has two routes:

  • Comply with radiated emissions limits of CISPR22 while adhering to CISPR22 measurement methods
  • Comply with radiated emissions limits listed in ICES-003 Issue 5 while adhering to ANSI C63.4 measurement methods

Limits
For AC Power line Conducted Emissions, the limits are harmonized with CISPR22 (Both class A and B).

For Radiated Emissions, the maximum frequency measurement range is harmonized with FCC part 15 subpart B.

For Radiated Emissions <1GHz, the limits are harmonized with FCC part 15 subpart B (Both class A and B).

For Radiated Emissions >1GHz, the limits are harmonized with FCC part 15 subpart B (Both class A and B), but requires measurements with both average and peak detectors.

Labeling
The new ICES-003 compliance label requirement is as follows: CAN ICES-3 (*)/NMB-3(*) where * is A or B

Not all ITE bound for Canada is subject to this standard.  Contact us to determine if ICES-003 is applicable to your equipment. 

Achieve compliance to other EMC standards for markets around the world.

China CCC Product Safety Compliance for A/V & IT Equipment is Changing

by admin on Jul.02, 2012, under China, Product Safety

Audio/video equipment and information technology equipment intended for sale in China must meet new China Compulsory Certification (CCC) product safety requirements starting in November and December, respectively.

In February, the Certification and Accreditation Administration of China (CNCA) Technical Committee for High Tech Industry finalized the certificate update instructions for both GB8898 (Audio, Video and Similar Electronic Apparatus – Safety Requirements) and GB4943 (Safety of Information Technology Equipment).  The updated standards are GB8898-2011 and GB4943.1-2011. The official change announcement was made April 10.

GB8898-2011 for A/V Equipment
After November 1, 2012, the China Quality Certification Centre (CQC) will only accept A/V equipment applications for the CCC Mark to the new GB8898-2011 standard.  From November 1, 2012 onwards, non-compliant products will not be permitted to be imported into or sold in the China market.

For A/V products marketed under existing certificates, manufacturers are required to update their certificates according to the new standard by November 1, 2013, with an additional grace period extending to February 1, 2014. All suspended certificates will be withdrawn by the CQC after February 1, 2014.

GB4943.1-2011 for IT Equipment
After December 1, 2012, the CQC will only accept IT equipment applications for the CCC Mark to the new GB4943.1-2011 standard.  From December 1, 2012 onwards, non-compliant products will not be permitted to be imported into or sold in the China market.

For IT products marketed under existing certificates, manufacturers are required to update their certificates according to the new standard by December 1, 2013, with an additional grace period extending to March 1, 2014. All suspended certificates will be withdrawn by the CQC after March 1, 2014.

KCC & MKE Change EMC, SAR & Product Safety Regulations in South Korea

by admin on Apr.02, 2012, under Korea

Following are recent and near future changes to electrical product regulatory requirements in South Korea.

Effective January 1, 2012, the Korean Communications Commission (KCC) requires radiated emission measurements at the limit, above 1GHz, by the highest internal source of the device and also conducted disturbance testing for devices with telecommunication ports. The limit is the same as CISPR 22:2006.

Effective July 1, 2012, the Ministry of Knowledge Economy (MKE) will assume responsibility for regulating safety of electrical products sold in Korea, a role currently carried out by KCC.  After July 1, KCC will only regulate IT/RF/Telecom products.

Effective January 1, 2013, KCC plans to expand its existing SAR requirements for mobile phones to include all radio equipment that is used within 20 cm of the human body. This harmonizes the Korean SAR requirements with FCC and other international standard requirements. Low powered radio devices (below 20mW) are exempt from this new requirement.

IEC 62368-1 Gains Prominence as Eventual Replacement for IEC 60950-1 & IEC 60065

by admin on Oct.05, 2011, under Product Safety

As the weeks and months march on, IEC 62368-1 elicits more chatter.  Designed to replace IEC 60950-1 2nd edition (IT equipment) and IEC 60065 7th edition (A/V equipment), the new product safety standard is not a merging of these two standards.

As new devices and applications emerge at an unprecedented rate, and technologies continue to converge, 60950-1 and 60065 have had to undergo numerous modifications, making them more complex and difficult to use.  IEC 62368-1 is designed for long-term stability and relevancy, regardless of product advancements.

Nearly ten years in development, 62368-1 covers a broad range of products, and allows for the minimalizing of national or regional differences.  Technology-neutral and performance – not prescriptive – based, the new standard is expected to help engineers integrate safety compliance early in the product design cycle and help manufacturers speed time to market. 

IEC 62368-1 Ed 1.0: Audio/Video, Information and Communication Technology Equipment — Safety Requirements is based on the principles of Hazard-Based Safety Engineering (HBSE).  Like the major risk-based change with IEC 60601-1 for electro-medical equipment, HBSE represents a paradigm shift for audio-visual, communication, and information technology products.

HBSE is a process that utilizes a three-block model to address the transfer of hazardous energy to a body part.  It describes methods to mitigate hazards and measure safeguard effectiveness.

IEC 62368-1 also has some new requirements to enhance product safety, including:

  • Methods for classifying energy sources
  • Definitions for ordinary persons, instructed persons, and skilled persons
  • Child accessibility test probe

Edition 1.0 of IEC 62368-1 was published as an international standard on January 10, 2010, with a minimum five year effective date recommended by IEC Technical Committee (TC) 108.  The second edition is planned to be published in 2013.  Final implementation of IEC 62368-1 second edition is likely sometime between 2015 and 2018. There will be a transition period where 60950-x, 60065, and 62368 will all need to be maintained.

Top 10 Tips for Designing Safety into Electrical Products

by admin on Sep.01, 2011, under Product Safety

Electrical Source Magazine features an article in its July/August 2011 issue that gives an overview on how to design electrical products to comply with safety standards including UL 60950-1, the safety standard for IT Equipment. “Working by Electrical Standards” was written recently by MET Laboratories Product Safety Engineer Tim Su.

The article describes the safety hazards, and provides preventive actions for each of these hazards. These design tips include:

  1. Own and read applicable standards
  2. Identify the potential hazards: electrical shock, electrical energy, risk of fire, mechanical, heat, radiation or chemical
  3. Choose properly certified and rated components
  4. Design in proper spacing and insulation
  5. Design enclosures taking those hazards into account
  6. Minimize openings
  7. Apply proper markings
  8. Develop a user manual and installation manual that include the proper safety precautions
  9. Maintain a file of data sheets and evidence of safety compliance of critical components
  10. Have your proposed design reviewed by a safety compliance specialist

Preventive design not only protects the end user, but also saves time and money for the manufacturer during the safety certification process.

EN55022 Changes Affect ITE Manufacturers Selling in EU

by admin on May.13, 2011, under EMC, Europe

There was much relief when the European Union postponed the cessation of EN 55022:1998 to October 1, 2011.  But now Information Technology Equipment manufacturers selling ITE products in the EU must face the music – EN 55022:2006 is upon us, as is Amendment A1:2007. 

Here is a basic primer on the changes:

EN55022:2006 is based on CISPR 22 Edition 5, released in 2005.  The major change in this edition was to remove the requirement for ferrite clamps to be used on cables exiting the test site.

Amendment A1 was issued by CISPR in 2005 also, and added requirements for testing above 1 GHz.  The EN version was released in 2007.

Testing above 1 GHz is designed to simulate a free-space environment, so the ground plane needs to be covered with rf-absorbing material to suppress reflections. In addition, the specifications require a very low reflection from around the EUT.

The CISPR 22/EN 55022 limits are 4dB lower than the U.S. FCC limits for measurements below 3GHz and identical above 3GHz.

As with FCC rules, the upper frequency of the measurement range for the CISPR 22/EN 55022 measurements is a function of the highest frequency generated within the product.

Results from tests conducted per the older versions can likely continue to be used in October 2011 to help support your Declaration of Conformity to the EMC or R&TTE Directives. To see what tests may need to be repeated, we need to look at each of the different tests in turn:

AC power port conducted emissions, 0.15-30 MHz
No change.

Telecommunications ports conducted emissions
New ISN specification should produce a lower measurement, so there is not likely to be an impact here.

Radiated emissions, 30-1,000 MHz
Re-evaluation without the ferrite clamps is required, as it could cause an increase in the levels of radiated emissions, primarily for emissions radiated by the interface cables to the remote equipment.

Radiated emissions above 1GHz
This is a new requirement for equipment with internally-generated frequencies above 108 MHz.

ENERGY STAR Testing and Certification Workshop for ITE Wraps Up

by admin on Dec.09, 2010, under ENERGY STAR

Today’s entry is a follow up to yesterday’s post, which covered the top takeaways from the first day of a two-day industry-sponsored workshop on ENERGY STAR testing and verification for IT equipment.  This entry covers the highlights of the second and last day of the Austin, Texas event.

The Environmental Protection Agency (EPA) will make exceptions for enterprise servers, workstations and some imaging equipment for verification testing to be witnessed at a manufacturer lab or location.

Some manufactures went over test procedures and data required for imaging equipment and servers.

ENERGY STAR Certification Bodies (CBs) – like MET Labs – can accept a test report from an accredited EPA-recognized lab for certifying Internal Power Supplies.

It was suggested all benchmarking (for servers and workstations) be performed by the manufacturer (ENERGY STAR partner). As of now, the manufacturer/partner will train and provide input parameters for LINPACK in peak power measurement and provide the benchmark software for their specific architecture/platform.

The EPA will distinguish between features that will have to be verified and those that can be claimed by a manufacture but not verified.

The IT industry requested a 6 month delay in the implementation of the new program because they think all the parties (manufacturers/partners, CBs and EPA) are not ready. They want to get it right rather than soon. The EPA representatives will discuss this with upper management.

EPA Outlines ENERGY STAR Testing and Certification Requirements for IT Equipment

by admin on Dec.08, 2010, under ENERGY STAR

Yesterday was the first day of a two-day industry-sponsored workshop on ENERGY STAR testing and verification for IT equipment.  As an EPA-recognized testing laboratory and certification body, MET Laboratories was on hand to take notes.  Following are highlights.

The workshop is being co-hosted by Dell & ITI at the Dell campus in Austin, Texas. In attendance are the EPA, 3rd party labs, and major ITE manufacturers: Lenovo, EMC², HP, Lexmark, Fujitsu, IBM, Dell, Oracle, Cisco Systems, Intel and AMD.

Program Updates

Partners will need to annually report unit shipment data.

CBs will still be permitted to manage certification marks related to their ENERGY STAR program – this will not be governed by EPA.

IT Products can be certified under the original certification scheme through December 31, 2010, with test reports due by February 1, 2011.  Following December 31, 2010 any new submissions for certification would need to go through the new 3rd party certification body program. 

EPA will continue qualification of products that are additions to a product family qualified prior to January 1, 2011, until the specification revision is effective.

If a manufacturer’s lab is separately accredited by EPA then no need for SMTL/WMTL.

ENERGY STAR Standard Operating Procedures (SOP)

EPA has a template for its Certified Product Data Submission.

There is no guaranteed reciprocity between CBs – a CB can reject another CB’s certification (or Lab’s report).

Rebranding will be managed via letter of equivalency.

Verifying Product Family Membership

Applicants must have a “representative” model tested with a justification for the choice: explanation on variations within the family, a list of models included in the family.  CBs need to maintain a list of all products in a family.  EPA will be the arbiter of any CB challenge as to whether or not a specific model may be deemed “representative.” 

Rule is to certify the least energy efficient configuration (worst-case scenario).

ENERGY STAR will provide clarification on definition of product differences for PCs and Servers via supplementary guidance on SOP.

CBs do not need to receive a product sample?   EPA thinks requirement that CB receive a sample should not be standard practice. 

Minimum Test Report Requirements:

  • Test procedure name listed
  • Test data listed
  • Serial number listed
  • Sample description
  • Equipment calibration dates and next due dates
  • Test engineer and witness names and signatures
  • Test results organized by applicable test procedure section and clearly marked to indicate results that are relevant to ENERGY STAR

SOP Appendix A – product-specific guidance contains power supply requirements for IT products. 

EPA shall be the final arbiter for all product-specific aspects of certification review that are unclear.

CB can certify a different brand without data review if already certified by the CB; EPA encourages CBs to work together to avoid duplicative testing and review; CBs need to flag models that are certified under different brand names and maintain a data field specific to the model tested.

CBs will be submitting data to EPA using the MESA interface on a bimonthly-monthly basis

Verification Testing

CBs annually test 10% of certified products by subtype.

Private Labelers: Brands A, B, and C are all one product for verification testing purposes. 

EPA will provide additional guidance on verification testing model selection.

All members of a family are subject to testing, but not more than one per round of surveillance testing.  Ten percent of a product family needs to be tested. 

Use of first party facilities are permissible only when off-the-line testing is the only practical option so long as CBs witness the test; CB must be able to justify why this is acceptable. 

WMTLs/SMTLs can perform verification testing as long as the CB witnesses it. 

Failure in Verification testing is when there is greater than 5% difference between certified and subsequent tested ratings. 

Challenge Testing

CB must judge the legitimacy of a challenge claim.  Challenge testing is limited to partner-to-partner challenges. 

Failure in Challenge testing is whether or not it meets ENERGY STAR product requirements. 

HP Presentation on Product Qualification Process and Checklist

HP urges product qualification to take into account supplier reality of manufacturers and development in Taiwan and China.  Says that it will take six months to fully implement ENERGY STAR requirements throughout its entire supply chain.

CBs will have to determine when the product introduction date is, so as not to announce information about the product before it debuts.

HP has listed all the various action items involved in the product qualification process.  This captures all the fundamentals the manufacturer will experience with ENERGY STAR qualification.  HP has also created a process description for SMTLs.

EN60950-1 2nd Edition Takes Effect

by admin on Nov.30, 2010, under Product Safety

IT manufacturers shipping to Europe take note:  Today is the last day for EN60950-1 1st edition.  Beginning tomorrow, all IT products must show compliance to EN60950-1 2nd edition. Products previously tested to EN60950-1 1st edition will not be grandfathered.

In general, the second edition adds consistency through clarification of either terminology or test methodology.  Here are some of the primary changes:

  • Section 2.6.3.4 – Resistance of Earthing Conductors and Their Terminations – now reflects the North American National Differences in the present CSA/UL 60950-1.
  • Section 2.3.2 – Separation of TNV Circuits from Other Circuits and from Accessible Parts – was necessary as the former standard did not match up with currently-accepted ITE handling of TNV circuits.
  • Section 4.2.11 – Rack Mounted Equipment – has new requirements for evaluating slide rail designs. However, these requirements do not apply to sub-assemblies that are not part of a completed rack/system cabinet.
  • Both Voltage Dependent Resistors (VDR) and Audio Components get expanded attention throughout the new version of the standard.
  • Good news for manufacturers of IT equipment weighing less than 15.4 lbs, as the 10° tilt stability testing will be waived.

Korea RRA Announces Phase Out of KCC Mark

by admin on Nov.15, 2010, under Korea

Korea’s Radio Research Agency (RRA) has just announced new regulation which will take effect January 24, 2011.

These changed regulations will significantly impact the current approval process for Korea. Listed below is the summary of changes:

  1. The KCC mark and logo will be changed to the KC mark, which will be the only mark for all Korea approvals.  This KC logo will be enforced from January 1, 2011.
  2. From January 24, 2011, four approval options will be changed to three new approvals.

The old approvals were:

  • EMC Approval
  • Telecom Approval
  • Wireless Approval
  • Wireless Registration

The new approvals are:

  • Compliance Approval (wireless products)
  • Type Registration (ITE products and industrial products)
  • Probable Approval (New products and developing products for which RRA does not have test standard)

For ITE, a RRA authorized lab needs to do the testing but there is no need to submit a test report to RRA.

In the case of Industrial products, the manufacturer can do the testing by itself and keep the technical documents for 5 years.
