00252a-000000-000000 1 Scope 1.1 These minimum requirements cover accessories intended for direct connection to the low or delivery pressure side of compressed gas regulators. These devices are not intended for direct connection to high storage cylinder pressures. 1.2...

SCOPE AND LIMITATIONS This standard establishes a method for conducting production hydrostatic testing of pressure regulator shells having bodies, bonnets, casings, and spring cases manufactured from any materials. This standard covers the hydrostatic testing of pressure...

The General Services Administration has authorized the use of this commercial item description as a replacement for MIL-R-36557C, which is cancelled. This commercial item description covers the requirements for a single stage pressure regulator, with a Thorpe tube flowmeter suitable...

Applicability. This standard shall apply to fire and explosion prevention during cleaning and purging activities for new and existing flammable gas piping found in electricgenerating plants and in industrial, institutional, and commercial applications. Coverage of piping systems shall extend...

Applicability. This code is a safety code that shall apply to the installation of fuel gas piping systems, appliances, equipment, and related accessories as shown in 1.1.1.1(A) through 1.1.1.1(F). (A)* Coverage of piping systems shall extend from the point of delivery to the appliance...

To provide basic regulator definitions and terminology relating to types, function, performance, parts, and design features.

Applicability. This standard shall apply to fire and explosion prevention during cleaning and purging activities for new and existing flammable gas piping found in electric-generating plants and in industrial, institutional, and commercial applications. Coverage of fuel gas piping...

ISO 23555-2 specifies safety, constructional, performance, testing and documentation requirements for gas pressure regulators for use in gas transmission, distribution and installations (hereafter referred to as regulators). ISO 23555-2 is applicable to...

002520-000000-000000 1 Scope 1.1 These minimum requirements cover regulators used to reduce the pressure of compressed industrial gases from a source or storage cylinder pressure of not more than 5500 psig (37.91 MPa) to the use pressure. 1.2 Regulators...

This standard specifies the connections on removable pipeline regulators and station outlets used in the welding, cutting, and allied processes where the pipeline pressure does not exceed 200 psi (1380 kPa).2 Removable connections are those that are commonly and readily engaged or...

This Standard applies to individual gas appliance pressure regulators, which are not a part of a combination control (see Clause 3, Definitions), constructed entirely of new, unused parts and materials, hereinafter referred to as regulators, intended for application on...

To provide a test methodology for measuring and reporting the capacity of pilot operated and direct acting pressure reducing regulators. PURPOSE This standard creates a guideline for establishing and reporting regulator capacities for use by manufacturers, users, specifiers and...

This standard provides a method for establishing and reporting back pressure regulator capacities for use by manufacturers, users, specifiers and approval bodies in order to promote consistent presentation of back pressure regulator or surplusing valve capacities. This...

Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. To determine a window regulator's performance when it is subjected to various wet...

Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. To determine the window regulator efficiency. Applicability. This procedure...

SCOPE & LIMITATIONS This standard applies to pilot operated and direct acting pressure reducing, pressure relieving (back pressure), differential pressure and temperature regulators. Selection of a leakage class is not restricted as to regulator design, but...

This standard covers regulators of the following types:
