See 5.2.4 for required retesting in the event of a failure to meet the specified minimum breaking strength.
For continuous production control, samples shall consist of a set of four specimens randomly selected from the current production batch, and be tested, prior to delivery, in accordance with Clause 5 in each of the four specified directions. The recommended minimum number of such samples to be tested is given in Table 1.
