1 Scope
This Part specifies generic skip-lot sampling procedures for acceptance inspection by attributes. The purpose of these procedures is to provide a way of reducing the inspection effort on products of high quality submitted by a supplier who has a satisfactory quality assurance system and effective quality controls. The reduction in inspection effort is achieved by determining at random, with a specified probability, whether a lot presented for inspection will be accepted without inspection. These procedures extend the principle of the random selection of sample items already applied in GB/T 2828.1 to the random selection of lots.
The skip-lot sampling procedures specified in this part are applicable to, but not limited to, inspection of
a) End items, such as complete products or sub-assemblies,
b) Components and raw materials, and
c) Materials in process.
