8 Elastocon – Rubber testing. Batch control. Batch control is the name given to the tests, which entails that each batch of mixed rubber is checked before it is used in any further processing. The testing can include the determination of viscosity, cure curve, density and hardness.
Rubber gasket materials such as cork and elastomers, cork and cellular elastomer and elastomeric treated materials are covered up in the standard for physical and mechanical characteristic requirements. The standard also provides test methods applicable for specific property test and guideline for selection of specification. 4.
BRC Rubber & Plastics, Inc. include the formulation of compound to customer requirement, production, assembly, inspection and testing of rubber products including rubber-to-metal and rubber-to-plastic. ISO 9001:2008 specifies requirements for a quality management system. BRC has
MonTech's application engineers are familiar with the individual requirements of many different fields in the rubber and polymer industry right down to the smallest detail, allowing them to tailor the testing solution exactly to the needs of the end user.
amount of sulphur in rubber (added sulphur, sulphur issued from raw materials). Determination of sulphur is carried out by several methods. The principle for all of them is oxidation of sulphur atoms onto sulphur dioxide or sulphates. Nowadays determination of sulphur is executed by the means of elementary analyzer.
Performance Testing of Rubber. Many rubber specifications include requirements for hardness (ASTM D2240), tensile strength (ASTM D412), elongation (ASTM D412), and volume change (ASTM D471) after fluid exposure (ASTM D471) and/or heat resistance (ASTM D573). Compression set (ASTM D395) is used to measure how much of a permanent set a rubber o-ring.
Glove System. A glove system consists of: Rubber insulating gloves – Classified by the level of voltage and protection they provide. . and 1.25 times normal for Type II during the air test. The procedure should then be repeated with the glove turned inside out. . they should be retested per ASTM D120-14a requirements. Testing.
Rubber Testing Solutions. Testing of rubber materials commonly requires test machines capable of measuring a very high strain in addition to testing at temperatures above and below ambient. Some of the most common test types within rubber testing are tear, tensile testing, compression testing and relaxation testing.
Oct 24, 2015· Suggestions are made for requirements for a small range of standard rubbers for three types of rubbers: dynamic rubbers (for springs and dampers); sealing rubbers; and hose rubbers. (N.G.G.) Read more
