This guide outlined the main areas of rubber testing, from natural rubber testing to mechanical testing, with specific details for 30 individual test methods and procedures, including details of the accompanying international test standards. 4.1 These test methods cover the evaluation of rubber materials or fabrics coated therewith subjected to low-temperature flex with an impact under well-defined conditions of striker speed. The response is largely dependent on effects of low temperatures such as crystallization, incompatibility of plasticizer, or the inherent dynamic behavior of the material itself. Rubber low temperature brittleness tester measures the highest temperature when vulcanized rubber is damaged due to an impact from test conditions, this temperature is called as brittle temperature. It identifies the difference between non-rigid plastic, flexible materials under low temperature. It also measures the brittle & low temperature .Brittle fracture in glass Brittle fracture in cast iron tensile testpieces. A material is brittle if, when subjected to stress, it fractures with little elastic deformation and without significant plastic deformation.Brittle materials absorb relatively little energy prior to fracture, even those of high strength.Breaking is often accompanied by a sharp snapping sound.
The following test methods can be used to assess the suitability of a compound in low temperature applications. We break these out into more detail throughout the rest of this blog post. Brittleness test: ASTM D2137; ISO 812; Low Temperature retraction test: ASTM D1329; ISO 2921; Low temperature stiffening test: ASTM D1053; ISO 1432This document was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 2, Testing and analysis. This fourth edition cancels and replaces the third edition ( ISO 812:2011 ), of which it constitutes a minor revision.
