CCSi manufactures these high quality UltraLife Specimen Cutting Dies for the determination of compression set, under constant force or constant deflection, as indicated in ASTM D395 ‘Standard Test Methods for Rubber Property — Compression Set’.
The Type 1 specimen die is used in both ASTM D395 ‘Test Method A’ and ‘Test Method B’, while the Type 2 specimen die is used solely for ‘Test Method B’.
While most CCSi cutting dies are available with mallet handles, arbor press mounts, or press adapters, the ASTM D395 specimen cutting dies are equipped with a special integral 0.375 inch diameter shaft. This facilitates mounting in a drill press, or similar device, as it is necessary to rotate the die while cutting the specimen.
The ASTM D395 Type 1 specimen die may also be employed in ASTM D575 ‘Standard Test Methods for Rubber Properties in Compression’, Test Method A — Compression Set of a Specified Deflection specimen preparation. However it is not identified directly as a D395 Type 1 specimen die as there is a slight, yet overlapping, dimensional difference between them (refer to the specifications below).
The D395 Type 1 die is directly referred to in ASTM D1229 ‘Standard Test Method for Rubber Property — Compression Set at Low Temperatures’ for use in preparing test specimens.
CCSi UltraLife specimen cutting dies are manufactured from homogenous, solid, high carbon content A2 tool steel. Each undergoes multi-axis precision grinding and conventional, plunge, or wire EDM (Electrical Discharge Machining) processes … producing a world-class, close tolerance die.
Precision grinding and EDM processes ensure true parallelism and multi-plane dimensional accuracy. The quality of materials, design, and engineering serve to provide the highest specimen quality possible, over an extended service life.
Where highly technical manufacturing techniques and processes end … old-world craftsmanship begins!
CCSi UltraLife specimen cutting dies are individually serialized, hand-honed, and mirror polished. A protective coating of industrial enamel is applied to the non-cutting surfaces before undergoing a rigorous final inspection.
Each UltraLife specimen cutting die includes a detailed final report and certification to the applicable standard, traceable to NIST, and compliant with ISO 9001:2000 and ISO/IEC 17025. The specimen dies are placed in a plastic, blow-molded, ‘clam shell’ style case with a foam lining to protect the die during transport and storage.
