ASTM D32 Committee on Catalysts has developed a standard test method for single pellet crush strength for formed alyst shapes. This standard was issued under the fixed designation D 4179. The method is applicable to regular alyst shapes such as tablets and spheres. Extrudates, granular materials, and other irregular shapes are excluded.

This specifiion covers the requirements for stainless steel bolts, hex cap screws, and stud bolts in imperial size inch to inch, inclusive for number of alloys in common use and intended for service appliions requiring general corrosion resistance.

A minimum initial box compression, as measured by Test Method D642 is determined using the weight on the bottom box and the F factor, see Then engineering principles are used to select material combinations based on material characteristics such as caliper, edge crush value, and flat crush to meet that requirement.

ASTM D3574 F covers the tear resistance of by the block method. Complete instructions for the tear strength test can be found in ASTM D3574 F which applies to slab, bonded, and molded flexible cellular urethane s (polyolefin s are tested similarly). Tear strength is determined by measuring the peak force during the tear test.

Chlorinated polyvinyl chloride (CPVC) is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin, which is significantly more flexible and can withstand higher temperatures than standard include hot and cold water delivery pipes and industrial liquid handling. CPVC, as PVC, is deemed safe for the transport and use of potable water

The compressive strength or crushextrusion resistance of a gasket material is a major factor with regard to the selection of a given material for use in a particular sealing appliion. The significance of the test method is based, in part, on the assumption that a material, once it has been crushed or extruded, will no longer function as effectively as a seal.
