Description

Establishes rules for batching, sampling, inspection and acceptance/rejection of asbestos-cement products. Provides for a uniform method to be used in determining the accordance of the asbest-cement goods with the relevant requirements for such products and a double sampling plan for the method of inspection by attributes as well as an alternative single sampling plan for the method of inspection by variables.

Scope

This International standard establishes rules for batching, sampling and inspection of fibre-reinforced cement products. These rules apply to all acceptance tests. In certain cases they may also apply to type tests but the sampling scheme for type tests will usually be specified in the product standards. These rules form a uniform method for determining whether consignments of fibre-reinforced cement products can be considered as conforming to relevant product standards.

This International standard also gives guidelines for internal sampling and inspection of finished products from a continuous production process, allowing the relaxation of the rules concerning acceptance or rejection of inspection lots providing that the appropriate conditions have been fulfilled.

The quality system of the factory is outside of the scope of this International standard.

  1. The sampling schemes are based on ISO 2859-1, ISO 3951, ISO 8422 and ISO 8423 with an AQL of 4 % and inspection level S3.
  2. According to the results obtained on previous batches, either a reduced or a tightened control is applied in accordance with these standards.

The methods of switching rules (normal, tightened or reduced inspection) are given in extracts of those standards reproduced in annexes A and B.
