Guidance on the selection and usage of acceptance sampling systems for inspection of discrete items in lots - Part 2: Sampling by attributes

Price from:
€ 56.87


The guidance given in this part of ISO/TR 8550 is confined to acceptance sampling of products that are
supplied in lots and that can be classified as consisting of discrete items (i.e. discrete articles of product).
Each item in a lot can be identified and segregated from the other items in the lot and has an equal chance of
being included in the sample. Each item of product is countable and has specific characteristics that are
measurable or classifiable as being conforming or nonconforming (to a given specification).
Standards on acceptance sampling by attributes are applicable to a wide variety of inspection situations.
These include, but are not limited to, the following:
a) end items, such as complete products or sub-assemblies;
b) components and raw materials;
c) services;
d) materials in process;
e) supplies in storage;
f) maintenance operations;
g) data or records;
h) administrative procedures.
Although this part of ISO/TR 8550 is written principally in terms of manufacture and production, it is applicable
to the selection of sampling systems, schemes and plans for all types of product and processes as defined in
ISO 9000.
