UltraLife Cutting Dies by CCSi
CCSi manufactures these high quality Specimen Cutting Dies for determining the cracking resistance of vulcanized rubber exposed under dynamic strain conditions to a chamber atmosphere containing ozone at a fixed partial pressure, as described in ASTM D3395Standard Test Methods for Rubber Deterioration — Dynamic Ozone Cracking in a Chamber’.
The effects of sun or ultraviolet light are excluded, those effect are considered in ASTM D1171 Standard Test Method for Rubber Deterioration—Surface Ozone Cracking Outdoors or Chamber (Triangular Specimens).
ASTM D1149 Standard Test Methods for Rubber Deterioration-Dynamic Ozone Cracking in a Chamber describes a dynamic tensile elongation / relaxation cyclic test (Method A, Procedure A1; formerly D3395 Method A) which determines, in a relative sense, the degree of ozone resistance of a material under the accelerated conditions of the test.
ASTM D1149 Standard Test Methods for Rubber Deterioration-Dynamic Ozone Cracking in a Chamber also describes a dynamic cyclical surface strain test. The strain is created by the flexing of the specimens, which are affixed to a fabric belt that rotates between two pulleys. ASTM Method A D3395 Specimen Cutting Die
ASTM D1149 Specimen Die
Method A, Procedure A2
(formerly D3395 Method B)
Commonly referred to as the 'Belt Flex Test', ASTM D1149, Method A, Procedure A2 (formerly ASTM D3395 Method B) is widely used, often in conjunction with other static or dynamic strain tests, to determine the ozone resistance of a material.
CCSi provides the OREC™ Ozone Chamber, which is suitable for performing Dynamic Ozone Tests when the DynaStretch option is selected. CCSi also offers molds and cutting dies used in other ozone test procedures.
CCSi UltraLife Specimen Dies: Quality Manufacturing
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.
