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.
