Provides guidance on the selection of quality control chart methods for process control, complementary to BS 5701 and 5703. Explains how control charts work and gives a procedure for the determination of process capability. Also provides a basic reference standard for both industrial training and technical educational purposes.

A method if inspection and determination of the resistance of glass containers to external force in the direction of the axis is specified. The pass tests are intended especially for containers the resistance of which is specified. The press with two horizontal flat steel pressure plates and the test method are specified.

This British Standard specifies an acceptance sampling system of double sampling schemes for inspection by variables for percent nonconforming. It is indexed in terms of the acceptance quality limit (AQL). The objectives of the methods laid down in this British Standard are to ensure that lots of acceptable quality have a high probability of acceptance and that the probability of non-accepting inferior lots is as high as practicable. This is achieved by means of the switching rules, which provide: a) automatic protection to the consumer (by means of a switch to tightened inspection or discontinuation of sampling inspection) should a deterioration in quality be detected; b) an incentive (at the discretion of the responsible authority) to reduce inspection costs (by means of a switch to a smaller sample size) should consistently good quality be achieved. In this British Standard, the acceptability of a lot is implicitly or explicitly determined from an estimate of the percentage of nonconforming items in the process, based on either one or two random samples of items from the lot. This British Standard is primarily designed for use under the following conditions: a) where the inspection procedure is to be applied to a continuing series of lots of discrete products all supplied by one producer using one production process. If there are different producers or production processes, this British Standard shall be applied to each one separately; b) where the items of product have a single quality characteristic (for multiple quality characteristics, see Annex A, Annex B and Annex C, which are all informative); c) where the quality characteristic is measurable on a continuous scale; d) where the measurement error is negligible (i.e. with a standard deviation no more than 10 % of the corresponding process standard deviation); e) where production is stable (under statistical control) and the quality characteristic is distributed, at least to a close approximation, according t
