A2LA - American Association of Laboratory Accreditation- a non-profit, professional membership society committed to the success of laboratories through the administration of a broad spectrum, nationwide laboratory accreditation system and a full range of training on laboratory practices taught by experts in their field.

Abrasion Resistance - The ability of a fiber or fabric to withstand surface wear and rubbing.

Accelerated Aging - A test method to represent extended aging of material in a shorter amount of time. For cellular rubber it is the process of artificially increasing time to measure physical property changes. This usually involves exposure to air at an elevated temperature.

Acrylic Adhesive - A pressure sensitive adhesive formed by the polymerization of acrylic ester monomers. These adhesives exhibit high temperature resistance, excellent U.V. resistance, good plasticizer resistance and good aging characteristics.

Ambient - an ambiguous term referring to a stable temperature environment of approximately 70°F or “room temperature.”

Antioxidants - chemical compounds or substances that are added to foams to improve their resistance to oxidation. An examples of oxidation in polyurethane foams is a gradual shift of color to yellow.

ASTM - Initials used as an abbreviation for the American Society for Testing and Materials, which is an organization devoted to the establishment of standard methods and procedures of testing materials.

ASTM D 1056-0 - American Society For Testing and Materials. This specification (D 1056) covers flexible cellular rubber products known as sponge rubbers and expanded rubbers. It is designed to provide certain physical property parameters and test methods for cellular rubber. The 98 stands for the revision year of 2000. Previous versions include 1998, 1991, 1985, 1978, 1968, 1967 & 1965.
