1.1This practice covers the preparation of specimens of mastics and coatings in the form of cured sheets or films that are used in other procedures for evaluation of physical properties.
1.2Three procedures are described for casting and curing (Note 1) mastics and coatings of all types for thermal insulation. When reinforcing mesh in recommended by the mastics and coatings manufacturer, test specimens shall be prepared using reinforcing mesh.
Note 1:The term “cure” is used primarily to denote the condition that develops as the result of loss of volatile matter but also to denote possible subsequent changes in chemical or physical properties due to crosslinking.
1.2.1Procedure Ais intended to provide a specimen of controlled thickness applied to the intended insulation for field use and equivalent in other respects to that obtainable under field application conditions.
1.2.2Procedure Bis intended to provide a free-film specimen of controlled thickness having smooth surfaces on both sides. This type is required for some types of physical testing.
1.2.3Procedure Cis intended to provide a free-film specimen of controlled thickness having one smooth surface (as field applied).
1.3The procedures of this practice are not intended for the evaluation of application properties. These are covered in Test Methods C461 and Guide C647.
1.4The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
