Five Tips for Avoiding Counterfeit Electrical Products

by admin on Dec.06, 2012, under Product Safety

Counterfeit electrical products are a huge and growing problem.  Counterfeit products worth billions of dollars enter the U.S. each year.  According to the U.S. Customs and Border Protection, 13% of all counterfeit products seized are electrical products, ranking them second among all category totals.

The manufacture of counterfeit electrical products is popular because the profits are outsized, and it’s difficult to pinpoint where bad products are originally made, and who is responsible for exporting them.

Generally, counterfeiters don’t go to the expense of having products tested and verified by an approved third-party testing lab designated as a nationally recognized testing laboratory (NRTL) such as MET Labs, but they will sometimes produce fake approval logos.

To lower costs, counterfeit products typically have substandard design, materials, and/or manufacturing quality.  Counterfeit electrical products present serious health and safety risks to consumers and to the electrical industry. These products can overheat or cause short circuits, leading to fires, shocks or explosions that can kill people and produce considerable property damage.

Manufacturers, distributors, and installers of electrical products also face legal risks for trading in counterfeit products — even if they are victims of counterfeiters.

To protect yourself from the purchase of counterfeit electrical products, observe these 5 guidelines.  If you are an electrical product manufacturer, encourage your customers to do the same – you never know when one of those bogus products will have your brand name on it.

  1. Buy from a reputable source.  Purchase products from the manufacturer’s authorized distributors or a known retailer.
  2. Examine labels, documentation and packaging.  Check for certification marks from organizations that certify the quality and performance of electrical products. Avoid products that lack any identifying branding label or have poor-quality labels, missing owner’s manual, out-of-date product codes, and suspect packaging.
  3. Verify authentication.  Use tools provided by the original manufacturer or certification organizations to verify electrical products are authentic. For a MET-safety-labeled product, verify authenticity in the MET Labs Online Safety Certification Database
  4. Examine the product.  Quality control is often lacking in counterfeiting operations, so you may be able to spot a counterfeit based on its workmanship.
  5. Avoid bargains.  If it seems too good to be true, it probably is.

If a product is suspected to be counterfeit, contact the brand owner and report your concern to U.S. Immigrations and Customs Enforcement: 1-866-347-2423.

E3 Energy Program and IEC 62368-1 Discussed by IECEE U.S. Committee

by admin on Mar.08, 2012, under ENERGY STAR, Product Safety

MET Labs participated in a meeting this week of the United States National Committee of the IECEE to discuss a number of issues. 

E3 Program
There was much discussion about the E3 Program (Energy Efficiency, Energy Performance & Energy Consumption), covered in Compliance Today previously.

The U.S. initially opposed the E3 Program because there is a lack of harmonization.  As it stands, there is no assured reciprocity and there is no certificate issued, just a Statement of Test Results (STR).  It is up to the reader of the STR to decide to accept or not.

IEC 62368-1
UL and CSA have recently published harmonized versions of IEC 62368-1. It will, however, likely be a long time before this becomes a NRTL standard due to OSHA’s workload and their likely objection to its inclusion of hazard-based analysis. Major labs will list to it, but if a product is going into the workplace, then 60950 or 60065 must still be used. 

Only the U.S., Sweden and Denmark have adopted 62368-1 in the Scheme per the CB website. Canada is to participate soon, as is France. The Netherlands may participate soon.

More about IEC 62368-1 is found in this Compliance Today post.

China EMC
China is not currently accepting EMC within the Scheme.  China’s objection may be that this was once voluntary and that the Scheme adopted EMC as mandatory and have not given China time to revise its standards.

Motors
At least one manufacturer thinks there is a need for motors to be in the safety CB Scheme.  The only place a motor standard is covered is within the EMC Scheme.  NEMA’s 1MG Section is continuing its conversation regarding the inclusion of electric motors as part of the E3 Program. 

Next meetings are May 22-23, 2012 in Vancouver, Canada, and August 7-8, 2012 in Orange County, California.

EU Association Accuses UL of Abusing Its Position in the U.S. Product Safety Certification Market

by admin on Dec.19, 2011, under Product Safety

In October, a European industry association published a strong-worded position paper that details how EU manufacturers suffer from the “malfunctioning of the U.S. certification market,” due to Underwriters Laboratories’ “abuse of its dominant position.”  The paper’s author, Orgalime, is the European Engineering Industries Association that represents some 130,000 companies in the mechanical, electrical, electronic, metalworking & metal articles industries of 22 European countries.

The complaint centers on the certification of components like control devices, circuit boards, cables, electrical connectors, power supplies, and switching devices.  Although component safety certification is not required under U.S. regulations as governed by Occupational Safety and Health Administration’s (OSHA) Nationally Recognized Testing Laboratories (NRTL) program, most component manufacturers do it anyway, to give confidence to end product manufacturers that are integrating the component.

There are 16 current NRTLs including MET Labs, according to the OSHA NRTL list.  All the NRTLs have the same legal standing and are viewed as technically equivalent, if their scopes of accreditation include the same U.S. national standard.  According to Orgalime, only one NRTL – UL – will categorically reject any component certification issued by another NRTL lab.  UL will issue a certificate for a complete product in which electrical components are embedded only if UL itself has certified the electrical components beforehand.

This is significant because UL controls more than 50 percent of the safety certification market, due to years of enjoying a virtual monopoly position.  The market was opened up in 1988 due to action initiated by MET Labs, but the legacy of market dominance continues.

According to Orgalime, this practice of denying recognition of component certificates delivered by other NRTLs causes a “de facto quasi-monopoly situation” from the component manufacturers’ viewpoint.  “This behaviour not only restricts the freedom of choice of manufacturers, but also proves to be expensive and causes delays in the development process of a machine.  Orgalime considers this situation as a classic case of market failure.”

Orgalime also points to UL’s anti-competitive behavior as a U.S. National Certification Body (NCB) within the International Electro-technical Commission’s (IEC) Certification Body (CB) Scheme.  Within this scheme, members agree to peer-review audits and mutual recognition of CB Certificates. In this case, UL is obliged to accept test results from all participating NCB’s, but the price which manufacturers have to pay for permission to use the UL logo based on testing results by another CB is higher than the entire testing procedure by UL itself including the contract for the use of the logo.

In a letter to European Trade Commissioners, Orgalime asks the European Commission to bring these concerns to the Transatlantic Economic Council to encourage U.S. authorities to correct the lack of obligatory recognition among the accredited NRTLs of component certificates.

Safety Certification to UL/IEC 61010-1 Evolves

by admin on Feb.04, 2011, under Product Safety

Product safety certification for healthcare & other laboratory equipment continues to evolve.  Thirteen months ago, on January 1, 2010, all new products and alternate constructions of listed or recognized products were required to be evaluated to UL 61010-1 2nd Edition.

The Second Edition combines UL 61010A-1 for laboratory equipment, UL 61010B-1 for test and measurement equipment and UL 61010C-1 for process control equipment into a single standard.

On January 1, 2014, UL 61010A-1, UL 61010B-1 & UL 61010C-1 will be withdrawn, and all listed and recognized products must comply with UL 61010-1 2nd Edition.

Europe is on a different schedule.  October 1, 2013 is the EU date of cessation for IEC 61010-1 2nd Edition.  (IEC 61010-1 2nd Edition is aligned with UL 61010-1 2nd Edition, except for some U.S. national differences in the UL edition.)

IEC published the Third Edition of 61010-1 in June 2010. See the abstract here.  Some of the major changes to the new edition include:

  • Scope now covers both professional and non-professional products
  • Test and measurement circuit requirements separated into a Part 2 standard: IEC 61010-2-30
  • Reworked Clause 6.7 and added Annex K for clearances, creepages, solid and thin film insulation and molded and potted parts
  • Temperature requirements modified due to EN563
  • X-ray requirements modified to include intended and non-intended emissions
  • New requirements for conformal coatings
  • New requirements for risk assessment
  • Added requirements for foreseeable misuse and ergonomics

The United States Technical Advisory Group (US TAG) and harmonization committee is working on the North American harmonized standards to IEC 61010-1 3rd Edition.  They are completing the National Differences and plan to have the standard developed and issued by the Spring of 2012.

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.
