6、d This Part of BS3762 has been prepared under the direction of the Chemicals Standards Policy Committee and supersedes BS3762-0:1989, which is withdrawn. BS3762 provides a series of analytical methods for formulated detergents, i.e.products ready for use (possibly after dilution) in solid, paste or

7、liquid form. The revised BS3762 is published in five Parts, the analytical methods in Parts3 and4 being published separately as Sections. The Parts together supersede BS3762:1964, which is withdrawn, and from which they differ in the following ways. a) Methods of analysis of detergent raw materials

8、are not included as they are published in BS6829 “Analysis of surface active agents (raw materials)”. b) Analytical methods applicable to all washing powders (including soap powders) are included. The test methods in BS1715 apply only to soap. c) The schematic examination of active matter has been w

9、ithdrawn. d) Certain physical and performance tests have been omitted. In preparing this revision of BS3762, the opportunity has been taken, if appropriate, to implement, preferably without alteration, International Standards describing test methods for surface active agents. These have been prepare

10、d, with the active participation of the UK, by Technical Committee91, Surface active agents, of the International Organization for Standardization (ISO). In this Part of BS3762, Table 1 gives the Parts and Sections of the standard and the analytical methods included therein and, where appropriate, t

11、heir relationships to the corresponding International Standards. The range of analytical methods, although wide, is not exhaustive and it is intended that work should continue with the object of improving existing test methods and preparing others for publication as further Sections of BS3762. BS376

12、2 does not include methods of sampling detergents from bulk. Guidance in this respect is given, however, in BS5309-1, BS5309-3 and BS5309-4. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct applica

13、tion. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 and2, an inside back cover and a back cover. This standard has been updated (see copyright date) and

14、 may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS3762-0:1991 BSI 10-1999 1 1 Scope This Part of BS3762 outlines, in Table 1, the structure of BS3762 and gives guidance on its use. NOTEThe titles of the publications referred to in this P

15、art are listed on the inside back cover. 2 Reagents During the analyses, unless otherwise stated, use only reagents of recognized analytical grade and water complying with grade3 of BS3978. 3 Other methods In addition to the methods given in Table 1, other British Standards appropriate for the analy

16、sis of formulated detergents include BS1647-1, BS1796 and BS3900-A11.
