1.1 These test methods cover those insulation products in specified Specification C208 . The requirements for the products’ physical properties are specified in Specification C208 . The methods for the general insulation products’ physical properties are given as follows: Section Thickness 7 Size of Finished Board 8 Thermal Conductivity 9 Transverse Strength 10 Deflection at Specified Minimum Load 11 Tensile Strength Parallel to Surface 12 Tensile Strength Perpendicular to Surface 13 Water Absorption 14 Linear Expansion 15 Water Vapor Transmission 16 Flame Spread Index 17 Moisture Content and Density 18 Compressive Strength 19 1.2 Reference is provided to an established source for nomenclature and definitions. 1.3 Several of the test methods contained in this document are referenced by material specifications other than cellulosic fiber insulating board. These include mineral fiber, perlite, polyisocyanurate, polystyrene and phenolic materials. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This 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. ====== Significance And Use ====== 4.1 The test methods contained in this document are intended for cellulosic fiber insulating board as described in Specification C208 . These test methods examine mechanical, physical and thermal properties, properties related to water absorption and water vapor exposure, and flammability related properties. 4.2 The results of these tests are suitable to describe the performance of insulating board and are also suitable for use in material specifications. Note 1: Committee C-16 is in the process of splitting this document into discrete test methods categorized by the nature of the test methods.
