The test piston shall have the dimensions specified in Figure 5 and shall be made of an elastic material which is inert against the test liquids and has a Shore-A hardness of 47 ± 5 (for example synthetic rubber).

When it is not possible to carry out the test on the specimens due to the shape/size of the product or the marking is not accessible with the test piston:

– a suitable piece having the same characteristics as the product can be submitted to the test

– another test piston with different shape can be used on the condition that radius B is kept.
