Application Specific Accessories
Foam compression fixtures are designed for indentation and compression testing of expanded cellular materials. Standards that require this style of fixture include ASTM D3574 (Method B1 and B2), ASTM D5672, and ISO 2439. The major components of the fixture include a perforated loading table and a circular indenter/anvil. The 203 mm diameter upper anvil incorporates a swivel joint. The base table is perforated with 6.5 mm holes spaced on 20 mm centers, and elevated from the mounting surface to allow for rapid air escape from the specimen.
Principle of Operation The specimen is placed on the perforated table attached to the instrument base. The indenter is brought down in contact with the specimen to establish a reference height. This is followed by a series of pre-conditioning loading segments and a test loading sequence. Data is captured during the test loading sequence, which generally includes a dwell time. Results are then calculated which commonly include loads at defined percent indentations or deflections.
Application Range • Indentation force deflection (IFD) and Compression force deflection (CFD) of expanded cellular materials • Suitable for an entire product or cut specimen • Suitable for specimens with or without skins
