12、 the direction of the Dairying Standards Committee. It is identical with ISO 5538:1987 “Milk and milk products Sampling Inspection by attributes”, published by the International Organization for Standardization (ISO). The sampling plans specified in the International Standard have been developed joi
13、ntly with the International Dairy Federation and the Association of Official Analytical Chemists, and will also be published by those organizations. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviati
14、on. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Whe
15、re the words “International Standard” appear, referring to this standard, they should be read as “Part of BS 7037”. Additional information. It is intended that BS 7037-2 will implement, when available, ISO 8197 “Milk and milk products Sampling Inspection by variables” which is in preparation. A Brit
16、ish Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

21、ying a unit as “good” or “defective”. A “good” unit is one which meets the requirements of a specification, while a “defective” unit is one which does not. It is essential that the sample is taken at random. If it is not, the sampling plans will not give the stated protection. See Annex A. 1 Scope a
22、nd field of application 1.1 This International Standard specifies sampling plans for the inspection by attributes of milk and milk products. It is intended to be used to choose a sample size for any situation where it is required to measure the conformity to a specification of a lot of a dairy produ
23、ct by examination of a representative sample. Methods of sampling for milk and milk products are given in ISO 707. 1.2 This International Standard is applicable to the sampling of all milk products submitted in discrete lots, irrespective of whether the lots are from the same production. The accepta
24、nce or otherwise of any lot is a matter for the parties to a contract and is outside the scope of this International Standard. 1.3 This International Standard is intended to be used in all cases where attribute sampling plans are required for a dairy product, except that if specific compositional st
