EUROLAB laboratory offers testing and compliance services under the ASTM C591 standard. This specification covers the types, physical properties and dimensions of uncoated, preformed rigid cellular polyisocyanurate plastic material intended for use as thermal insulation on surfaces from surfaces. –297°F (–183°C) to 300°F (149°C). Actual temperature limits for specific applications will be decided by the manufacturer and purchaser.
This specification covers only "polyurethane modified polyisocyanurate" thermal insulation, commonly referred to as "polyisocyanurate" thermal insulation. This standard does not cover all materials modified with polyurethane. Polyurethane modified polyisocyanurate and other polyurethane materials are similar, but the materials will perform differently under some service conditions.
This standard is intended as a material specification, not a design document. Physical property requirements vary with application and temperature. The physical properties of polyisocyanurate insulation at service temperature are particularly important at temperatures below –70°F (–51°C). Below –70°F (–51°C), the manufacturer and purchaser must agree on what additional cold temperature performance characteristics are required to determine whether the material will perform adequately for a particular application.
This standard addresses the requirements for uncoated preformed solid cellular polyisocyanurate thermal insulation manufactured using blowing agents with an ozone depletion potential of 0 (ODP 0).
The requirements in this standard specification, with the exception of 6.2 and 8.2 – 8.4, which relate to the size and shape of manufactured parts, and 16.1, which relate to the storage of fabricated parts, the insulation manufacturer.
Codes that address fire properties in many applications, when adopted by a competent authority, regulate the use of thermal insulation materials covered by this specification. Fire characteristics are controlled by the business, project, or other specification to which rules or government regulations do not apply.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.
This international standard has been developed in accordance with the internationally accepted principles of standardization set out in the Principles decision on the development of international standards, guidelines and recommendations published by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
