Hardness

The hardness of rubber compounds is measured by the Shore A durometer; the higher the durometer, the harder the compound 70-durometer hardness should be used whenever possible as it offers the best combination of properties for most O-Rings applications.

The Importance of Durometer

Jan 02, 2018· International Rubber Hardness Degrees - IRHD Scale Many organizations are now using the IRHD Scale which is a tester used for curved surfac The size and shape of the indenter is much smaller, therefore allowing for a more accurate reading on curved surfaces such as an O-ring.

A Guide to Shore Hardness and Why It’s Important When

Shore Hardness Testing and Scal An o-ring’s durometer is the measurement of that specific material’s hardness This scale is also measured by an instrument called a durometer gauge, which uses a spring-loaded rod to indent the material and provide a reading.

Shore durometer

The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials Lower numbers indicate less resistance and softer materials.

The Importance of Shore A Hardness

Sep 20, 2016· It is an industry standard test for rubber, and it is an acceptance criteria for every batch of O-ring material mixed by Parker What is Shore A hardness and how is it tested? Shore A hardness testing is performed using a durometer, which was developed by Albert Ferdinand Shore in the 1920’s The Shore A hardness measurement is often.

What is a Durometer?

The basic test requires applying the force in a consistent manner, without shock, and measuring the hardness (depth of the indentation) If a timed hardness is desired, force is applied for the required time and then read The material under test should be a minimum of 64 mm (25 inch) thick.

Durometer / Shore Durometer

Shore hardness, especially Shore A and Shore D, is commonly used for determining foam hardness, soft plastic hardness and rubber hardness, like in rubber o-ring testing Because of the popularity of the Shore hardness method, a durometer is often referred to as a Shore durometer.

Shore MicroHardness Durometer Tester for ASTM D2240 Type M

The Shore® Micro Hardness Tester was modeled after the familiar ASTM D2240 Type A durometer, however it employs a much ‘lighter’ mainspring and a considerably ‘smaller’ indentor This makes the Shore® Micro Hardness tester quite suitable for its intended purpose, yet too delicate to be used as a hand held instrument.
