Effective Date (see Schedule below): November 6, 2015
Impact Statement: A review of all Listing Reports is necessary to determine which products comply with new/revised requirements and which products will require re-evaluation. NOTE: Effective immediately, this revised standard will be exclusively used for evaluation of new products unless the Applicant requests in writing that current requirements be used along with their understanding that their listings will be withdrawn on Effective Date noted above, unless the product is found to comply with new/revised requirements.
Overview of Changes: The August 26, 2014 update includes revised requirements for automatic safety shutoff valves and gas flow controls. The October 29, 2014 update includes revised requirements of the accelerated aging test evaluation requirement for gaskets made of neoprene or rubber compound. Specific details of new/revised requirements are found in table below.

Fees: An initial review of Listing Report (s) will be covered by a direct billing project and will be invoiced at not more than $1000 per report.
