ISA-RP92.04.02, Part II, applies to all oxygen detection instruments that satisfy the performance requirements in ANSI/ISA-S92.04.01, Part I, Performance Requirement for Instruments Used to Detect Oxygen-Deficient/Oxygen-Enriched Atmospheres.

Definitions of terms, as used herein, are referenced in Clause 3 of ANSI/ISA-S92.04.01, Part I.

References useful in the installation, operation, and maintenance of oxygen detection instruments are listed in Annex C. These references are not considered to be part of this document, except for those specific clauses of documents referenced elsewhere in this Recommended Practice.

Purpose

This Recommended Practice establishes user criteria for the installation, operation, and maintenance of instruments used to detect oxygen-deficient/oxygen-enriched atmospheres.

Its companion Standard, ANSI/ISA-S92.04.01, Part I, provides minimum requirements for the performance of instruments used to detect oxygen-deficient/oxygen-enriched atmospheres.
