12、sh insoluble in hydrochloric acid” published by the International Organization for Standardization (ISO). In the UK, animal feeding stuffs are controlled by legislation. This Part of BS 5766 is technically equivalent to the method given in The Feeding Stuffs (Sampling and Analysis) Regulations 1982.
13、 Terminology and conventions. The text of the International Standard has been approved as suitable for publication, without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the followin
14、g. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The comma has been used throughout as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Additional info
15、rmation Water. Water complying with the requirements of clause 6 and 10.1.2 is specified in BS 3978 “Water for laboratory use”. NOTE 1With reference to sampling and the preparation of test samples, attention is drawn to The Feeding Stuffs (Sampling and Analysis) Regulations 1982, which provide guida
16、nce and which are to be followed for legislative purposes. NOTE 2In 9.1.2.1, lines 5 and 6, the phrase “previously set at 550 C” means that the temperature is 550 C when the dish is transferred into the furnace. A British Standard does not purport to include all the necessary provisions of a contrac
17、t. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
