Shore Hardness Type D

The durometer comes manufacturer calibrated and can be optionally certified to iso standards for an additional fee see accessories for details. Ptcs shore d scale durometer gauges are for determining indentation hardness of epoxy acrylic fiberglass hard rubber vinyl cellulose acetate pipeline coating and other similar materials. The pce ddd 10 shore d durometer is a portable handheld device used to check shore d hardness in hard rubber and thermoplastic.

Top Shore Hardness Type D, This digital durometer has a reading accuracy of 01 hardness units.

Shore hardness type d. A durometer measures the penetration of a metal foot into the surface of a material. Tpes can range from 10 shore 00 up to 72 shore d spanning all three hardness scales however the most commonly used is the shore a scale. The positector shd shore hardness durometer measures the shore indentation hardness of non metallic materials such as polymers elastomers and rubbers. Shore apparatus for measuring the hardness of materials issued 1930 07 08.

We carry durometers that meet or exceed astm d 2240 din iso and jis standards. Us patent 1770045 a. There are two common methods of expressing the hardness of rubber and plastics. Defelsko also manufactures the positector bhi barcol hardness impressor which is ideal for measuring the hardness of soft metals aluminum aluminum alloys copper brass etc harder plastics and fiber reinforced plastics.

The indentation hardness is inversely related to the penetration and is dependent on the elastic modulus and viscoelastic behavior of the material. 41 this test method is based on the penetration of a specific type of indentor when forced into the material under specified conditions. Semi rigid plastics can also be measured on the high end of the shore a scale. The shore a hardness scale measures the hardness of flexible mold rubbers that range in hardness from very soft and flexible to medium and somewhat flexible to hard with almost no flexibility at all.

The shore d hardness scale measures the hardness of hard rubbers. The durometer reading or shore hardness and youngs modulus of elasticity. We offer asker durometers as well as shore a durometers shore d and the rest of the shore scale.

A written calibration report for any durometer covered by current astm d2440 or astm f1957 specifications is available from ptc metrology certification provides as received and as left data. There are different durometer scales but shore a and shore d are the most common. Shore hardness and how it relates to other properties. Where is the astm d2240 type a hardness is the astm d2240 type d hardness and is the youngs modulus in mpa.

Shore hardness is often used as an indication of flexibility or stiffness which is called flexural modulus.
