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

by 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.

NRTLs Can Do Some Mexico Certifications in Lieu of NOM

by on Sep.30, 2010, under Mexico

The Mexican governments’ Secretary of Commerce officially announced last month that it will accept products certified to certain ANSI/UL and CAN/CSA standards by an NRTL/SCC approved lab in lieu of the NOM Certification.

Normally, NOM certifications can only be obtained in-country. However, an exception is made in these instances where the UL and CSA standards are similar to the NOM standards:

  • For ITE products, in lieu of NOM-019-SCFI-1998, manufacturers can certify to ANSI/UL 60950-1 (Ed. 2 Mar 27 2007) or CAN/CSA-C22.2 No. 60950-1-07 Second Edition.
  • For A/V products, in lieu of NOM-001-SCFI-1993, manufacturers can certify to ANSI/UL 60065, Seventh Edition (2003) or CAN/CSA-C22.2 No. 60065-2003 + Amendment 1: 2006.
  • For household appliances, in lieu of NOM-016-SCFI-1993, manufacturers can certify to ANSI/UL 60335-1 or CAN/CSA-E60335-1/4E-03 (R2007).

It’s a misperception that only a couple laboratories are recognized to do this testing.  All laboratories – including MET Labs – that meet ISO/IEC Guide 65, are approved by OSHA as NRTLs, and as a Certification Body by the SCC, will be recognized as third party testing organizations for products shipped into Mexico.

From the Mexico Secretary of Commerce’s website:

“por cualquier otro acreditado en el campo de aplicación de las normas citadas y conforme a la Guía ISO/IEC 65, y para el caso de los Estados Unidos de América que también sean reconocidos por la Occupational Safety and Health Administration (OSHA) de los Estados Unidos de América.”


“any other [lab] accredited in the field of application of the mentioned standards and according to Guide ISO/IEC 65, and for the case of the United States of America that also is recognized by the Occupational Safety and Health Administration (OSHA) of the United States of America.”
