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.

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.”
