Organization: UL
Publication Date: 1 April 1999
Status: inactive
Page Count: 54
scope:

These requirements cover pressure regulators for use with LP-Gas equipment.

Regulators covered by these requirements are intended for use in non-refrigerated systems in accordance with the following standards:

a) Liquefied Petroleum Gas Code, (National Fire Codes, Vol. 2) NFPA 58;

b) National Fuel Gas Code ( IAS/A.G.A. Z223.1), NFPA 54;

c) Outdoor Cooking Gas Appliances, IAS/A.G.A. Z21.58; and

d) Standard on Recreational Vehicles (RVIAA119.2) (National Fire Codes, Vol. 7), NFPA 501C.

These requirements do not cover:

a) Compressed gas regulators;

b) Gas appliance pressure regulators;

c) Regulators for use in chemical, petroleum, or utility power plants; pipeline or marine terminals; or related storage facilities at such plants or terminals;

d) Combination gas control valves for gas appliances;

e) Regulators for use in oxygen-fuel, gas-welding, and cutting operations; and

f) Regulators for use in engine fuel (automotive and/or marine) applications.

The requirements for (a) - (e) are covered in the Standard for Compressed Gas Regulators, UL 252, and in the Standard for Gas Appliance Pressure Regulators, IAS/A.G.A. Z21.18, and in the Standard for Combination Gas Controls for Gas Appliances, IAS/A.G.A. Z21.78, respectively.

The assigning of flow ratings to regulators is not within the scope of these requirements, and observations of flow values are required to ascertain stability characteristics within the manufacturer's rated capacity. These requirements include tests to verify outlet pressure stability characteristics within the manufacturer's rated capacity. The manufacturer is to submit this data prior to the investigation of the device. See the Flow Test, Section 22, regarding the outlet pressure instability definition.

A product that contains features, characteristics, components, materials, or systems new or different from those covered by the requirements in this standard, and that involves a risk of fire or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally anticipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conflict with specific requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the methods employed for development, revision, and implementation of this standard.
