Sampling procedures for inspection by
attributes - Part 3: Skip-lot sampling
procedures
(First revision)
(ISO 2859-3:2005, IDT)
(Published by Standards Malaysia in 2018)
This part of ISO 2859 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. This procedure extends the principle of the
random selection of sample items already applied in ISO 2859-1 to the random selection of lots.
The skip-lot sampling procedures specified in this part of ISO 2859 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.
