Early Consideration of EMC & Product Safety Compliance in Product Development Saves Time and Headaches
When developing a new electrical product, early consideration of electromagnetic compatibility (EMC) and product safety compliance issues will pay major dividends later.
If compliance is not engineered in from the start, expect to endure this pain:
- A major delay as the product is redesigned, jeopardizing time to market and product viability
- Significant extra costs for rework and increased product cost
- Team dissension and rock-bottom morale
What’s the best way to integrate compliance into a new product? First, get buy in from senior management, then:
- Buy and read the relevant safety and EMC standards and train your design engineers in the basics of compliance
- Have your compliance engineers work side by side with the designers, providing deeper expertise when needed, and information about the latest changes to standards and regulations
- Perform early design reviews and early testing on the first prototypes to lower the risk during final compliance testing
Don’t have a compliance engineering team? We can help. In addition to testing and certification, MET Labs offers compliance assistance, with controls in place to prevent a conflict of interest, as required by our accreditation agencies.
On February 15, 2013 the national Russian certification system GOST R and national Russian technical regulation “On Safety of Machinery Equipment” (Russian government order N 753 of September 15, 2009) were withdrawn.
Simultaneously, the new Customs Union Technical Regulation (CU TR) for most electrical products was enforced in Russia, Belarus and Kazakhstan.
Earlier issued GOST R certificates will be valid until March 15, 2015. After that, the new EAC mark must be used.
There are a number of changes in the CU TR for manufacturers of mass-produced products. Here are a couple of the most significant:
- The certification applicant must have a formal relationship (contract) with a Russian representative legal entity. With GOST, this was not required.
- Mandatory factory audits are performed by a Russian certification body. With GOST, a test lab could do this.
Following is a list of new Customs Union Technical Regulations for electrical products (all in Russian):
- On the Safety of Low-Voltage Equipment
- Electromagnetic Compatibility
- On Safety of Machinery Equipment
- On Safety of Equipment for Explosive Atmospheres
- Safety of Lifts
- On Safety of Equipment Operating on Gaseous Fuels
What is IEC 62368-1?
It is the new safety standard for Information Technology Equipment and Audio/Video Equipment. It is intended to replace IEC 60950-1 and IEC 60065. It is a hazard-based, performance-oriented standard.
Is IEC 62368-1 a risk-based standard?
No! Unlike IEC 60601-1, 3rd Edition, risk analysis is not required. Neither is it a simple merger of IEC 60065 and 60950-1.
Why are IEC 60950-1 & 60065 being replaced?
Technology is changing, and IEC 62368-1 is technology independent. It also minimizes the need for national/regional differences.
Is IEC 62368-1, Edition No. 1 being adopted internationally?
The United States (ANSI-UL 62368-1), Canada (CSA C22.2 No 62368-1), Denmark, Netherlands, & South Africa adopted national versions. Edition No. 1 was not supported by Europe (CENELEC), which wanted further refinement of requirements before adoption. In Asia, multiple countries are doing a close study of it. For the IECEE CB Scheme, IEC 62368-1 has been activated under OFF/TRON. OFF & TRON account for over half of CB Scheme certifications.
What is the status of IEC 62368-1, Edition No. 2?
Edition No. 2 of IEC 62368-1 (108/495A/CDV) was distributed in December and has a closing date for voting by TC108 National Committee Participating members of March 1, 2013. The U.S. TAG TC108 will reportedly submit an affirmative vote on the CDV. The IEC target publication date is the second half of 2013. Then, it is expected that Europe will adopt EN 62368-1, 2nd edition, with a likely 5 year effective date. The target publication date of Edition No. 2 of CSA/UL 62368-1 is summer 2014, with a likely 5 year effective date.
When will IEC 60065 & 60950-1 be transitioned out?
It is expected the last versions of IEC 60065 (8th edition) and IEC 60950-1 (2nd edition,
Am. 2) will be published in 2013. In Europe, the final versions of EN 60065 and EN 60950-1 are expected to be published in 2013 with a likely 3 year effective date. For the U.S. & Canada, final versions of CSA/UL 60065 & 60950-1 are expected to be published in 2014, with a likely 3 year effective date. For the EU & North America, new certifications of A/V, IT & CT Equipment are likely to be required to comply with an IEC 62368-1 based standard beginning around 2018.

New Requirement for Dimmable CFLs and LEDs
The meeting agenda began with a roundtable, which was focused on dimmers. EPA has encouraged consumers to transition to CFLs and LED bulbs to save energy, but their performance with dimmers has sometimes been less than optimal. Some dimmers are exhibiting flickering, noise and limited dimming. As a result, consumers are getting frustrated and switching back to incandescent bulbs.
The EPA is establishing a working group to introduce some basic requirements for all ENERGY STAR-labeled dimmable lamps/bulbs. It will include requirements for:
- Dimmer level
- Noise level
The test method is based on recommendations from NEMA and LRC (Lighting Research Center). The EPA is also considering a proposal to have building codes include dimmers for both CFLs and LED bulbs.
Lighting Certification Update
There are also updates on some new standards being developed for lighting certification, which are as follows:
- LM-84: To measure lumen and color maintenance of LED lamps, light engines and luminaires
- LM-85: To measure electric and photometric measurements for high power LEDs
- TM-26: To project rated life for LED packages
- TM-28: To project long term lumen maintenance of LED lights based on LM-84 data
Consumer Electronics Expansion
For consumer electronics, EPA intends to expand the product category in 2013 to include:
- Small Network Equipment
- Climate Control
- IP Phones
- Game Consoles
In 2013, there will be standard revisions for:
- Set-Top Boxes
- Battery Charging Systems
Touch and voice activation functionality will also be evaluated to implement as a function of energy for products with such features.

This post is the second of two posts on hazardous location product safety testing and certification. The first post explored testing for UL/CSA, ATEX & IECEx.
This post looks at certification requirements for particular markets/countries.
In the United States, the Occupational Safety and Health Administration (OSHA) governs the Nationally Recognized Testing Laboratories (NRTL) program, and accredits laboratories like MET Labs to product safety certify products. Hazardous location products must meet normal location and hazardous location requirements.
In Canada, Standards Council Canada (SCC) accredits labs to certify hazardous location equipment.
European Union (EU) Member Countries
The CE Marking, which includes the ATEX Directive and any other applicable Directives, is mandatory for equipment offered for sale or use within the EU. Equipment must bear all applicable markings (EN 60079 Series) and must be accompanied by a Manufacturer’s Declaration of Conformity.
Other Directives may also apply, such as PED for pressure equipment, Machinery Directive and EMC.
Australia, New Zealand, and Singapore
These countries require an IECEx Certificate of Conformity issued by an accredited IECEx Certification Body (ExCB), and equipment must bear the applicable markings outlined by the IEC 60079 series of standards.
Note also that for mining equipment, some jurisdictions within Australia require the IECEx Certificate of Conformity to be issued by an Australian ExCB.
For above ground (non-mining) hazardous location equipment, China has an IECEx Certification Body and will accept an Ex Test Report (ExTR) and/or an ATEX Report as a basis for issuing Chinese national certification. Generally, hazardous location equipment which is approved under the ATEX or the IECEx Scheme can be reviewed and issued a certificate by NEPSI (National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation) or CQST (China National Quality Supervision and Test Center for Explosion Protected Products).
Some products may also need metrology approval, MA mining certification, fire safety approval or CCC marking for general electrical safety.
Russia has an IECEx Certification Body and will accept an Ex Test Report (ExTR) and/or an ATEX Report as a basis for issuing national certification.
A GOST-R certificate is required for most electrical products shipped through Russian customs. For products intended for hazardous locations, the GOST-Ex certificate is required. The IECEx or ATEX certificate and ExTR or ATEX Report can be used to obtain the GOST-Ex. In addition, a permit for use from the Federal Ecological, Technological and Atomic Supervision Service (Rostekhnadzor) is required for the intended installation.
Korea accepts an Ex Test Report (ExTR) and/or an ATEX Report as a basis for issuing national certification. There are three main certification bodies: KGS, KOSHA and KTL. Applications must be made in Korean.
India is a member of the IECEx Scheme, but there are no Indian certification agencies currently accredited as ExCBs. There are a number of certification agencies within India, and an ATEX or IECEx Certificate and Report will help in obtaining National Certification for India.

Safety testing and certifying products for hazardous locations is complicated, especially when a manufacturer is exporting to multiple markets. Following is a basic primer. For more detailed information or questions, contact MET Labs.
In countries with formal certification and a 3-zone system, the IEC60079 series of standards is commonly used, adopted as National Standards as they are written or with some National Deviations that ensure compatibility with local installation codes.
Most all other countries that produce their own National Standards base them on the IEC 60079 series. Some countries, like the U.S. and Canada, have dual standards systems: National Standards, plus adoption of the IEC60079 series as an alternate system.
CE Marking/ATEX Directive
All EU countries require CE Markings, which involves the ATEX Directive for products used in hazardous locations. The use of harmonized EN standards gives the manufacturer the “presumption of conformity” to the “Essential Health and Safety Requirements (EHSRs)” and a basis on which to issue a declaration of compliance for the ATEX Directive.
The ATEX Directive requires:
- ATEX EC Type Exam Certificate, which documents the evaluation and testing of the subject equipment, performed to the applicable EN 60079 Standards, which are an adoption of the IEC 60079 Series with National Deviations for ATEX markings. The certificate is issued by a Notified Body (NB).
- ATEX Quality Assessment Notification (QAN), which documents the suitability of the manufacturer’s QA system, performed to the EN13980 Standard. The notification is issued by a NB.
- Declaration of Conformity (DoC) stating compliance with all applicable Directives. The DoC is issued by the manufacturer for Zone 2 certifications. Zone 1 and Zone 0 DoC certifications are issued by the NB.
For certain types of equipment (non-electrical for Zone 1 or both electrical and non-electrical for Zone 2), it is possible to self-declare compliance.
The IECEx Scheme is the CB Scheme for electrical equipment used in explosive atmospheres (hazardous locations). It consists of three elements, all issued by an IECEx Scheme Certification Body (ExCB):
- IECEx Test Report (ExTR), which documents the evaluation and testing of the subject equipment, performed to the applicable IEC 60079 Series Standards
- IECEx Quality Assessment Report (ExQAR), which documents the suitability of the manufacturer’s QA system, performed to OD 005 (EN13980)
- IECEx Certificate of Conformity (IECEx CoC), which can be issued to a manufacturer holding an ExTR and an applicable ExQAR.
In alliance with UK-based TRaC Global, MET offers testing, certification and product inspection services under the ATEX Directive and the IECEx Certified Equipment Scheme, via an innovative Harmonised International Ex Testing Program. Read more about it.
Last month, MET Labs attended a CTIA Battery Certification Program meeting in San Antonio, Texas. The agenda included a review and update of the certification program documents (CRD, PMD, CRSL). There was also a discussion to expand the program to include battery life testing. In attendance were all the system vendors, CTIA-Approved Test Labs (CATLs) and carriers such as Verizon and AT&T.
Some of the key updates made in the Certification Documents were:
- The manufacturing location as well as the entity controlling the design of the battery shall both meet the ISO 9000 requirements.
- System or cell operating outside its temperature or voltage range shall be shut down and not allow 911 calls.
- CTIA will adopt the definition of coin cells in UN 38.3 to define the appropriate battery chemistries that can be considered under IEEE 1725.
- Adapters shall be compliant with USB-IF Battery Charging Specification Rev 1.2 and OMTP1.1 to avoid compatibility issues (and slow charging rates) between different OEM chargers and devices.
- Burr control will be harmonized in CRDs for both IEEE 1625 & 1725.
- Battery identification is required for both embedded and user-replaceable battery packs.
- Battery packs installed in its host and normal application of the device is above head level, the drop height shall be 1500mm; for all others the drop height shall be 1000mm.
There was also a proposal to include battery life testing mainly for smart phones. The proposal included creating a working group to develop an accurate battery life test standard for smart phones that will cover the following parameters:
- User profile
- Network settings
- Device settings

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.
