On the other hand, the Shore hardness test uses a spring-loaded needle for plastic hardness testing. And like other hardness testing methods, a force is applied to the needle. This penetrates the plastic as far as it can, then measurement of the indentation depth estimates the plastic’s hardness. The Shore hardness scales used for measurement .XHR-150 Manual Plastic Rockwell Hardness Tester is a specialized test non-metallic, plastic, hard rubber, synthetic resin, friction material and soft metal hardness.

For rubbers, elastomers & softer plastics, Shore Hardness is often preferred. Very soft materials can be measured using Shore A hardness. It is generally used for hard materials, like PA, PC

A Vickers hardness tester. There are three main types of hardness measurements: scratch, indentation, and rebound. . A hardness number is just a semi-quantitative indicator of the resistance to plastic deformation. Although hardness is defined in a similar way for most types of test – usually as the load divided by the contact area – the .What standard test methods measure hardness of plastics? ISO 2039-1:2001 — It determines the hardness of plastics. It uses the ball indentation method. ISO 2039-2:1987 — It determines the hardness of plastics. It uses the Rockwell hardness scale.A Vickers hardness tester. The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. [1] The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter .

The hardness of plastics and hard rubber can be determined using a loaded ball indenter in accordance with standard ISO 2039-1 or ISO 2039-2. Standard ISO 2039-1 describes determination of the hardness value by means of a ball indenter test.The measured indentation depth is used to calculate the surface area of the indent and subsequently the hardness.

Testing rubber, polymer and a wide variety of other substances often require hardness testers and durometers; thats why MSC carries a full selection of these and other quality testing tools, meters and comparators. When your profession or industry relies on accurate readings of hardness levels, make MSC your first choice. .A Rockwell hardness tester. The Rockwell scale is a hardness scale based on indentation hardness of a material. The Rockwell test measures the depth of penetration of an indenter under a large load (major load) compared to the penetration made by a preload (minor load). [1] There are different scales, denoted by a single letter, that use different loads or indenters.Load: 98.1, 29.4 N. The HR-530 series offers five different hardness testing methods: Rockwell, Rockwell Superficial, Brinell, Brinell Depth Measurement and Plastic Testing in a single unit. This makes it a versatile .

Here you will find plastic and rubber hardness testers divided by the level of automation. From simple to fully automatic and motorized hardness testers, portable or benchtop, analogical or digital, with the complete range of testing loads conforming to ASTM E2240 / ASTM 1415 / ASTM D1414 and ISO 7619 / ISO 48 / ISO 868.Hardness testing within the realm of materials testing. Today, hardness testing is one of the most widely used methods in mechanical materials testing, especially for metals. On the one hand, this test method can be used to find qualitative relations to other material properties (e.g., strength, stiffness, density) or to the material behavior under certain stresses (e.g., abrasion .

The hardness testing of plastics is most often measured by the Rockwell hardness test or Shore (durometer) hardness test. Both methods measure the resistance of the plastic toward indentation, thereby providing an empirical .

In rubber and plastic hardness testing, hysteresis measurements can be used to evaluate the durability of materials under various loading conditions, including fatigue and creep. Fatigue testing involves subjecting the material to cyclic loading until it fails, while creep testing measures the material's deformation over time under a constant load.Rockwell hardness is used to compare the hardness of metals but there are Rockwell hardness scales suitable for the harder plastics such as polycarbonate (PC), nylon (PA) and acetal (POM). Overall, there are thirty different Rockwell hardness scales because, like Shore hardness, the same testing procedure is not suitable for all types of metals. For plastics hardness testing, there is a wide range of testers that allow for a variety of plastics to be tested. This testing equipment is becoming more sophisticated. "Some testers use a computer to control the amount of load that will be applied-via a load cell-and for how long," says Phil Eusebi, technical support at United Testing Systems .The Shore hardness testers/durometers are used for determining the hardness of plastics and rubber according to standards ISO 48-4, ASTM D2240, ISO 868, NFT 51109 and BS 903 Part A26.For on-site testing on the product, analog versions with and without drag-pointer are available. The Shore hardness testers with drag pointers simplify testing, particularly in .
