Scope
 

1.1 These requirements cover accessories intended for direct connection to low pressures, such as that of the delivery pressure side of compressed gas regulators. These devices are not intended for direct connection to high pressures, such as that of a fully-charged storage cylinder.
 

1.2  Accessories covered by these requirements are intended for use with compressed gases such as air, carbon dioxide, inert gases, fuel gases, nitrogen, nitrous oxide and oxygen.
 

1.3  The suitability of an accessory in combination with a compressed gas regulator shall be judged under the applicable requirements of the Standard for Compressed Gas Regulators, ANSI/CAN/UL/ULC 252.
 

1.4  These requirements do not cover:

       a)  Flow characteristics;

       b)  The physiological effects of accessories to be used with medical gases;

       c)   Accuracy of pressure gauges and flow indicators; nor

       d)   Accessories that are covered by other UL standards.

Project need:

The Standard will provide a means for certification programs to support efficient inspection and approval of products in Canada and the U.S.A., and hence promoting the safe use of these products. AHJs are increasingly reluctant to use ORDs and Outlines for regulatory requirements. Stakeholders have requested that we convert these in to a standard.
