Diagram of a durometer indenter or presser foot used for Shores A and D 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.
Il durometro è un modello standard per misurare la durezza della gomma ( Shore D).
A durometer gauge or durometer tester is needed to perform a durometer hardness test procedure. Durometer devices determine the surface hardness of many different materials, including polymers and elastomers. Originally, the result was just signified by a number, for example durometer.
As time progresse multiple durometer scales were created. La scala Shore è pensata per testare la durezza degli elastomeri o dei plastomeri, ad esempio gomma o plastica, caratterizzati da deformazioni reversibili.
Si misura la deformazione elastica del materiale in termini di profondità di penetrazione di una punta tronco conica mobile ( Shore tipo A) che inizialmente fuoriesce di mm dal foro di un piattello ed è soggetta a una forza costante. Choose a durometer scale specifically for measuring skateboard wheels, rubber tires, gym shoe soles, or textiles.
We also offer all the durometer tester accessories you might need. Keep your Shore durometer working accurately with our durometer calibrator or develop a “feel” for your durometer hardness gauge with our test block kits. These scales were invented so that people can discuss these materials and have a common point of reference. Der Shore-Durometer war weder der erste Härtetester noch der erste, welcher Durometer (duro-und -meter) genannt wurde.
Find Durometer Shore Scale. Shore (Durometer ) Hardness Testing of Plastics.
Whether you’re an engineer or an everyday hobbyist, understanding durometer hardness is key to ensuring your molds come out perfect. Shore, through his New York-based Shore Instrument and Manufacturing Company Inc. Shore hardness (or Shore durometer ) A-scale.
Used in the following types of materials: Hard thermoplastic, hard rubber and plastic high hardness, plexiglass, polystyrene, sheet vinyl, cellulose acetate, thermostatic and laminated formica. Despite this, the test is not used to predict a range of other property such as strength or resistance to scratches, abrasion or wear, and so, when it comes to design specifications, it should not be relied upon solely.
You may redistribute it, verbatim or modifie providing that you comply with the terms of the CC-BY-SA. The PCE-OO durometer is a standard device for measuring soft elastic and textiles ( Shore OO). The Shore A hardness measurement is called ‘’ durometer ’’.
Hardness of Polymers (rubbers, plastics) is usually measured by Shore scales.
Shore A scale is applicable for rubber and soft plastics whereas Shore D is for hard rubber and thermoplastics. They use a specific spring force and indenter shape combination to measure the indentation depth created and resistance according to the applicable test standard. Il dispositivo può essere utilizzato nell’industria degli strumenti radio, nell’ingegneria meccanica e in altri settori dell’industria moderna.
View Shore Durometer Hardness Scale Infographic. Shore D Hardness is a standardized test consisting in measuring the depth of penetration of a specific indenter.
The hardness value is determined by the penetration of the Durometer indenter foot into the sample. Table of Shore Durometer Scales. Theromophysical Data.
Key data on over two hundred and fifty polymers. Hardness may be defined as a material’s resistance to indentation. Shore Hardness measures are dimensionless.
The instrument as well as the unit of measurement is called as a Durometer. The durometer scale was defined by Albert Ferdinand Shore. Today, the name usually refers to shore hardness.
Durometer is used to measure the hardness of polymers, elastomers and rubbers. Durometers measure in the scale of Shore and the most common varieties are Shore A and Shore D.
