Historical Standard: ASTM C461-81(2003) Standard Test Methods for Mastics and Coatings Used With Thermal Insulation
SUPERSEDED (see Active link, below)
ASTM C461
1. Scope
1.1 These test methods cover procedures for sampling and testing mastics and coatings for use as weather and vapor barrier finishes on thermal insulations and for other accessory use.
1.2 The values stated in inch-pound units are to be regarded as the standard. The metric equivalents of inch-pound units may be approximate.
1.3 The test methods appear in the following order:
| Section | |
| Sampling | 4 |
| Uniformity and Storage Stability | 5 |
| Stability Under Freezing | 6 |
| Density and Weight per Gallon | 7 |
| Consistency | 8 |
| Solids Content | 9 |
| Content of Volatiles and Coverage of Mastics and Coatings | 10 |
| Build | 11 |
| Drying Time | 12 |
| Flash Point | 13 |
1.4 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
