Rubber, NR - Shore A hardness 40, high elastic - Part 4: Resilient elastomeric elements
Title (German)
NR-Elastomer - 40 Shore A, hochelastisch - Teil 4: Elastomer-Federelemente
Overview
The material specification documents the properties, test procedures and tests on the standard specimen with the corresponding units and formula symbols. NR elastomer spring elements generally exhibit high tensile strength, elasticity and relatively good cold properties. Resistance to mineral oils or greases is low or non-existent. The committee responsible for the material specification is standardization committee NA 132-02-10 AA "Schock- und Schwingungsdämpfung" ("Shock and vibration decrement").
