American National Standard For Pipe Joint Sealing Compounds And Materials Edition: 1st
CSA Group / 01-Feb-2009 / 46 pages

Preface
This publication represents a basic standard for acceptable performance of pipe joint compounds and materials. It is the result of years of experience in the manufacture, testing, inspection and research on pipe joint compounds and materials designed for use with natural gas and LP gas piping systems.
Scope
1.1.1
Part I and Part II of this standard cover paste, semi-liquid or liquid type pipe joint sealing compoundswhich are intended for sealing threaded joints on metal piping having NPT tapered threads.
1.1.2
A minimum of 3 containers of sealing compound, each not exceeding 16 oz (0.45 kg) in weight, shall be submitted.
1.1.3
This standard sets forth the minimum capabilities, characteristics and properties which the product must possess at the time of manufacture in order to be considered suitable for use in natural and/or LP-gas piping systems.
1.1.4
Compounds or materials shall have an operating temperature range of at least 32 degrees F to 125 degrees F (0 degreees C to 51.5 degrees C) to be considered suitable for use in indoor piping systems, and at least -40 degrees F to 125 degrees F (-40 degrees C to 51.5 degrees C) to be considered suitable for indoor and outdoor use. A manufacturer may specify and be tested to temperatures outside of these ranges.
1.1.5
Compounds or materials shall have an operating pressure of at least 125 psi (861.8 kPa). A manufacturer may specify and be tested to higher pressures.
1.1.6
Room temperature, as specified herein, shall be considered as 73.4 degrees F 3.6 degrees F (23 degrees C 2 degrees C).
1.1.7
Sealing compounds and materials complying with the provisions of this standard shall be considered as having an operating temperature range and maximum operating pressure as specified by the manufacturer.
1.1.8
If a value for measurement as given in this standard is followed by an equivalent value in other units, the specification.
1.1.9
All references to psi throughout this standard are to be considered gage pressures unless otherwise specified.
