Un durometro Shore è uno strumento che misura tipicamente la durezza degli elastomeri e di certi polimeri termoplastici. Determina la profondità di sfondamento di un penetratore normalizzato mediante semplice applicazione sul campione. These scales were invented so that people can discuss these materials and have a common point of reference. The Shore AScale measures rubbers and gels that are very soft.
It is measured by the depth of indentation that is created on the material with a specified force. They are arguably the best seal for many applications, but perhaps daunting to an engineer with no experience in seal design.
The steal rod is either configured as a frustum cone ( Shore A ) or a needle pin ( Shore D). Hardness A and hardness D. You could get this item at an unbeatable price! This pocket sized digital durometer with round shape and large LCD display. This high quality and durable hardness durometer is used for testing the objective with low hardness.
This rubber durometer chart gives you an idea of the hardness you want for your O-ring or rubber part. With this sensitive, efficient, . This scale or chart is in the Shore A range which most rubber materials fall under. Shore hardness is tested with an instrument called Durometer.
The measured hardness is determined by the penetration depth of the indenter under the load. Durometer utilizes an indenter loaded by a calibrated spring. Two different indenter shapes (see the picture below) and two different spring loads are used for. Thermoplastic Elastomers are measured in Shore A and Shore D according to ISO 868. Shore A hardness not exceeding are exempt from the relevant provisions.
It is determined as a number from to 1on the scales A or D. The higher the number, the higher the hardness. The test measures the penetration of a specified indentor into the material under specified conditions of force and time. The hardness value is often used to . The most common instrument used for measuring hardness is Shore Durometer.
It measures the depth of penetration of an indenter on a scale from zero to a tenth of an inch ( in.). A zero reading indicates that . For on-site testing on the product, analog versions with and without drag-pointer are available. The instruments with drag-pointers simplify testing, . Applies to general rubber, synthetic rubber, soft rubber, poly-resin, wax, etc.
These test methods are used to determine the hardness of plastics and elastomers. Roun clearly arranged and antiglare scales. The scales graduation is 0-1Shore , divided in 1units.
Getting the right O-ring for your application means getting the right hardness.
