CETA Technical Update

CETA Technical Update

By Jimmy Welch / Published March 2021

In the November 3 and 4, 2020, Technical Harmonization Committee (THC) 335H meetings, the manufacturer members unanimously requested that the Underwriters Laboratories UL 1776 Standard for Safety for High-Pressure Cleaning Machines withdrawal date of March 1, 2021, be extended. UL reviewed the request and decided to remove the withdrawal date.

     Manufacturers that currently have products listed to ANSI/UL 1776 can continue to use it as well as list revised or new products.


  

     Manufacturers that currently have product listed to ANSI/UL 60335-2-79 can also continue to use it as well as list revised or new products.

     Currently THC 335H is working on harmonizing the US and Canadian standards for a binational standard, UL/CSA 60335-2-79, to assist manufacturers.

     On January 6, 2021, UL sent an email to its subscribers notifying them of the decision. It came from Christopher Hutchings, engineering manager, and states the following:

     This bulletin is to advise subscribers that the effective date to transition from UL 1776 to UL 60335-2-79 has been canceled.

     UL proposed in a bulletin dated November 20, 2020, to cancel the effective date for the Industry File Review (IFR) to transition to UL 60335-2-79. During the comment period, UL received no negative responses, and in view of this, the effective date is being canceled.

     As stated in the aforementioned bulletin, the effective date of cancellation is based on a request from the Technical Harmonization Committee (THC) members responsible for the development of UL/CSA 60335-2-79 and high-pressure cleaning machines manufacturers.

     UL is canceling the March 1, 2021, effective date until the UL/CSA 60335-2-79 standard is published, and a new effective date established to transition from UL 1776 to the new standard UL/CSA 60335-2-79. High-pressure cleaning machines can continue to be certified to either UL 1776 or UL 60335-2-79 prior to this new effective date.
