CCSi manufactures these high quality UltraLife Specimen Cutting Dies for the determination of volume resistivity of rubbers used in electrically conductive and antistatic products, as described in ASTM D991 ‘Standard Test Method for Rubber Property — Volume Resistivity Of Electrically Conductive and Antistatic Products’.
It is assumed that the surface conductivity is exponentially less, comparatively, than the conductivity through the subject material.
The test specimens, dimensionally specified in ASTM D991, are specific only to their thickness, which varies dependent upon whether the specimen is molded for the purpose of the test, or obtained from an article.
The molded specimens are to be prepared in accordance with ASTM D3182 ‘Standard Practice for Rubber—Materials, Equipment, and Procedures for Mixing Standard Compounds and Preparing Standard Vulcanized Sheets’. CCSi also manufactures the D3182 ‘standard laboratory mold’ required for this purpose.
The specimen width may vary from 10 – 150 mm (0.4 – 6.0 inch) being uniform within ± 1%, and the length from 70 – 150 mm (2.8 – 6.0 inch), these being dependent upon the end user’s requirements.
Therefore, these dies are manufactured individually to the specifications enumerated by the user. CCSi cutting dies are available with mallet handles, arbor press mounts, or press adapters, which facilitate the user’s specific specimen preparation protocol.

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.
