PRESSURE RELIEF DEVICE STANDARDS—PART 1— CYLINDERS FOR COMPRESSED GASES

active, Most Current
Organization: CGA
Publication Date: 1 January 2022
Status: active
Page Count: 52
scope:

This standard applies to the selection of PRDs for a single component compressed gas in cylinders. For selection of PRDs for compressed gas mixtures in cylinders, see CGA S-7, Standard Method for Selecting Pressure Relief Devices for Compressed Gas Mixtures in Cylinders [5].

This standard does not cover PRD requirements for CTC/DOT-4L and TC-4LM insulated cylinders containing cryogenic liquids, see CGA S-1.2, Pressure Relief Device Standards-Part 2-Portable Containers for Compressed Gases [6]. This standard does not cover PRD requirements for multi-unit tank car tanks (DOT106A/TC106A and DOT110A-W/TC110A), see 49 CFR 179.300-15 and CGSB 43.147, Construction, Modification, Qualification, Maintenance, and Selection and Use of Means of Containment for the Handling, Offering for Transport, or Transporting of Dangerous Goods by Rail, as appropriate [1, 7].

This standard includes tables that provide information pertaining to PRDs. Table 1 contains information on the different types of PRDs. Table 2 provides a list of gases and their PRD assignments. Table 3 contains temperature correction factors. Table 4 includes values for basic orifice factors flange taps for flow in ft3/minute.

For PRD standards for bulk transport containers and stationary storage containers, see CGA S-1.2 and CGA S-1.3, Pressure Relief Device Standards-Part 3-Stationary Storage Containers for Compressed Gases [6, 8].
