Friability of Spray-Applied Fireproofing and Thermal Insulations: The Basis for a Field Test Method

摘要

The investigation was Phase 1 of a two part study to develop a test method that can be used in the field to measure the friability of spray-applied fireproofing and insulating materials containing asbestos fibers. Four test methods were selected; compression/shear, indentation, abrasion, and impact. For each of the four tests, mechanical devices were devised by modification of existing material test apparatus. A description of the test devices is given in the report.
