4.1 Classification of insulation relative to flexibility or rigidity is useful in establishing installation and application characteristics.1.1 These test methods cover the procedures for the classification of mineral fiber insulation as flexible, resilient flexible, semirigid, or rigid.1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.3 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.1.4 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.

4.1 It is possible that insulating blocks or boards that are not true or square will not fit properly. It is possible that extra labor will be required to obtain proper fit and that this could affect the product performance as well as the appearance of the finished installation.4.2 This test method provides terminology and describes locations for obtaining consistent measurements of trueness and squareness of blocks and boards.1.1 This test method covers locations for measuring the trueness and squareness of rigid block/board thermal insulation. This test method does not purport to address the variability in board thickness. Thickness is addressed in other ASTM standards.1.2 The 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.1.3 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.1.4 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.

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.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:  SectionThickness  7Size of Finished Board  8Thermal Conductivity  9Transverse Strength 10Deflection at Specified Minimum Load 11Tensile Strength Parallel to Surface 12Tensile Strength Perpendicular to Surface 13Water Absorption 14Linear Expansion 15Water Vapor Transmission 16Flame Spread Index 17Moisture Content and Density 18Compressive Strength 191.2 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.
