ASTM C534/C534M Standard Specification for Preformed Flexible Elastomeric Cellular Thermal Insulation in Sheet and Tubular Form
ASTM C534片式和管式预制柔性弹性体蜂窝状绝热材料的标准规范
This specification covers sheet and tubular preformed flexible elastomeric cellular thermal insulation. The materials are classified into three grades according to the operating temperature range of the industrial systems that each material is used for. The non-thermoplastic, thermoset products should be made of natural or synthetic rubber that may be modified using various thermoplastic or thermosetting resins, plasticizers, modifiers, antioxidants, curatives, blowing agents, and other additives. All products should be tested using the prescribed procedures and conform to the specified values of apparent thermal conductivity, water absorption, water-vapor permeability, and linear shrinkage.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers preformed flexible elastomeric cellular thermal insulation in sheet and tubular form. Grade 1 covers materials to be used on commercial or industrial systems with operating temperatures from -183 to 104°C [-297 to 220°F], Grade 2 covers material used on industrial systems with operating temperatures from -183 to 175°C [-297 to 350°F], and Grade 3 covers material used on industrial systems with operating temperatures from -183 to 120°C [-297 to 250°F] where halogens are not permitted.
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 and health practices and determine the applicability of regulatory limitations prior to use.
