Product Description

CCSi manufactures this high quality UltraLife Specimen Nicking Apparatus for precision nicking of Type A & B (ISO 34) specimens, as described in ASTM D624 ‘Standard Test Method for Tear Strength of Conventional Vulcanized Rubber and Thermoplastic Elastomers’.

In order to perform the Type A and Type B (ISO 34) Tear Tests with high levels of accuracy and precision, the propagation of the tear is a most critical element. This device virtually eliminates error … greatly improving both repeatability and reproducibility!

The test specimens are securely held in place by a spring loaded handle, guide, and backing plate assembly (shown in blue and red). The frame and specimen receptacle (shown in silver) are precisely machined to accommodate up to six specimens and designed to ease their precise positioning.

The guide for the cutting blade (shown in green) rests securely in the rigid frame. It is engineered to smoothly guide the cutting blade precisely through the specimen, creating a ‘nick’ at the prescribed depth of 0.50 ± 0.05 mm (0.020 ± 0.002 inch) with unparalleled repeatability. The preparation process is improved by producing statistically identical specimens.

The UltraLife ASTM D624 Nicking Apparatus is manufactured from 304L stainless steel and anodized aircraft grade aluminum. The parts are EDM (Electrical Discharge Machining) and CNC (Computer Numerical Control) machined from homogenous solid material. The quality of design, materials and manufacture, as well as the ease of use, set this device apart from others of similar purpose.
