What is the process for developing, and current status of the next CSA & UL 62368-1 bi-national standard to be based on IEC 62368-1:2018 (Ed. No. 3)?
The Technical Harmonization Committee (THC) for 62368-1 has been collaborating throughout 2018 on proposed content for the next edition of the bi-national standard, CSA/UL 62368-1, Ed. No. 3. This edition will replace Edition No. 2 of CSA/UL 62368-1, published in 2014.
The THC consists of,
- Canadian Subject Matter Experts (SMEs) from Industry, incl. AV, IT & CT (telecom) disciplines
- U.S. SMEs from Industry
- CSA & UL SMEs
- CSA & UL Standards Development Organizations (SDO) representation.
For this edition, both the Chair & Secretary functions now are held by members from Industry. (In the past UL had been requested to hold these positions.)
The purpose of the THC is to develop and propose to the CAN & US SDOs content of National Differences (NDs) from the international standard that together with IEC 62368-1:2018 base content will be published as CSA C22.2 No. 62368-1/UL 62368-1 Edition No. 3.
For Edition No. 3, factors influencing revised or new NDs from the previous edition include aspects such as, the latest (2017) National Electrical Code (NEC), the latest (2018) Canadian Electrical Code (CEC), updates to CSA & UL component standards, and increased representation from the communication technology (telecom) equipment industry sector on the THC.
When the THC has agreed via consensus on material to move forward, the material is handed off to the SDO functions in Canada and the U.S.
In Canada, the proposed material generated by the THC is reviewed by the CSA Subcommittee (CSC) for TC108/62368 in accordance with Standards Council of Canada (SCC) rules, which also includes a period for public comment.
In the U.S., the same material is reviewed by the UL Standards Technical Panel (STP) for 62368 in accordance with American National Standards Institute (ANSI) rules, which also includes a period for public comment.
Both processes include formal voting, and upon successful votes the CSA/UL Standard is considered to be both SCC & ANSI approved (national standards for Canada & U.S.).
As of mid-December 2018, the THC anticipates wrapping up, and handing off its work to the CAN/US SDOs in early 1Q 2019, which then begins the formal CAN & US SDO processes. These formal adoption processes are expected to be advanced through 2019, with a target publication date no later than end of 4Q 2019 for CSA/UL 62368-1 Ed. No. 3.
At that time, the CSA/UL standard can be used for Ed. No. 3-based Marks for Canada and the U.S.
