a way of assessing the hardness of materials. Shore A (for softer materials such as elastomers and plastics) measures the depth of penetration of an intender under specified conditions.
In the case of a projection consisting of a component made of non-rigid material of less than 50 shore A hardness mounted on a rigid support, the requirements of points 5.1.4 and 5.1.5 shall apply only to the rigid support.
