More G It emphasizes factors that cause ignition and enhance propagation throughout a system's service life so that the occurrence of these conditions may be avoided or minimized. It is not intended as a specification for the design of oxygen systems.
The interrelationships among the standards are shown in Table 1. Guide G88 deals with oxygen system and hardware design principles, and it is supported by a regulator ignition test see G Other standards cover: 1 the selection of materials both metals and nonmetals which are supported by a series of standards for testing materials of interest and for preparing materials for test; 2 the cleaning of oxygen hardware which is supported by a series of standards on cleaning procedures, cleanliness testing methods, and cleaning agent selection and evaluation; 3 the study of fire incidents in oxygen systems; and 4 related terminology.
Specifically, this guide addresses system factors that affect the avoidance of ignition and fire. It does not thoroughly address the selection of materials of construction for which Guides G63 and G94 are available, nor does it cover mechanical, economic or other design considerations for which well-known practices are available.
This guide also does not address issues concerning the toxicity of nonmetals in breathing gas or medical gas systems. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. Avoid Unnecessarily Elevated Temperatures. Avoid Potentially Exothermic Material Combinations.
Anticipate Common Failure Mechanism Consequences. Avoid Unnecessarily-Elevated Oxygen Concentrations. Anticipate Permutations from Intended System Design. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. However, Manual 36 is not a balloted technical standard. Scope 1. Note 1 — The American Society for Testing and Materials takes no position respecting the validity of any evaluation methods asserted in connection with any item mentioned in this guide.
Users of this guide are expressly advised that determination of the validity of any such evaluation methods and data and the risk of use of such evaluation methods and data are entirely their own responsibility.
