AQL quality limit which in a sampling plan corresponds to a specified but relatively high probability of acceptance; it is the maximum per cent defective (or the maximum number of defects per hundred units) that, for purposes of sampling inspection, can be considered satisfactory as a process average [ISO 3534, see definition] 3.12 finished part part ready for use, inclusive of any possible treatments and/or surface coatings, as specified in the dimensional standard or drawing 4 Certification and quality assurance 4.1.1 Qualification 4.1.2 Purpose The purpose of acceptance tests is to check, as simply as possible, by a method representative of actual use conditions, with the uncertainty inherent to statistical sampling, that the bolts constituting the batch satisfy the requirements of this standard 4.1.3 Conditions The acceptance tests are summarized in Table 3. They shall be performed on each batch. Table 1 specifies the test method and sampling plan to be used for each test. Bolts from the batch to be tested shall be selected by simple random sampling. Each boIt may be submitted to several tests. The bolts to be subjected to destructive tests may be those on which non-destructive tests have been performed. 4.2 Quality system certification SIST EN 3389:2009

Tolerances of form and position Tolerances of form and position shall conform to the product standard or drawing. Tolerances of form and position shall be controlled by an approved system of gauging.
5.2.3
Threads Threads shall conform to the product standard or drawing. Threads shall be gauged by an approved system of gauging.
5.3
Manufacturing Parts may be manufactured by machining from material EN 2960 or by forging from material EN 2959 or EN 3220.
NOTE It is possible to finish grind the diameter and under head, and cold roll the fillet radius of close tolerance parts after precipitation treatment.
See also 5.3.3.3.
