Relays, Electromechanical Elementary UL 61810-1


Description

The introduction of UL IEC-based standards for industrial control equipment required finding a home in the IEC world of standards for products covered by UL 508, the long-standing North-American based standard for industrial control equipment. While most products covered by UL 508 matched the scope of the IEC 60947 series of standards, relays did not. The IEC 61810 series of standards was determined to be the appropriate requirements for relays. The first edition of UL 61810-1, Electromechanical Elementary Relays – Part 1: General Requirements was published in July 2015. It is an IEC-based standard for relays to provide certification requirements that facilitate the application of relays in the global marketplace. This is possible as UL 61810-1 is well-harmonized with IEC 61810-1.

The workshop focuses on how to select, interpret and apply the appropriate requirements for evaluating relays in accordance with the first edition of UL 61810-1. It covers the critical parts of UL 61810-1, scope of standard, terms and definitions, influence quantities, general provisions for testing, specific test procedures, construction specifications and much more.

Also included will be an explanation of the development of UL 61810-1 and the transition of relay certifications from existing UL categories to a new certification category for relays.

  

Each participant will receive a participant workbook and a copy of the UL 61810-1 Standard ($567 USD value).
