Unlike the UNI 6365-74 standard, the sample does not have a pre-established number, but is collected in a sequential manner, that is, after each determination of the characteristic on an element it is possible to reach one of the following decisions:
——accept the lot;
——reject the lot;
——request another test to be carried out.
