7、6, Uncontrolled Copy, (c) BSI BS 6829-0:1991 ii BSI 12-1999 Foreword This Part of BS 6829 has been prepared under the direction of the Chemicals Standards Policy Committee. It is a revision of the 1989 edition of BS 6829-0, which is withdrawn. BS 6829 provides a series of analytical methods for surf
8、ace active agents used in their unbuilt form or used as raw materials for formulated products. BS 6829 is published in six Parts, the analytical methods in Parts 1 to 5 being published separately as Sections. In preparing this British Standard, the opportunity was taken, if appropriate, of implement
9、ing, preferably without alteration, International Standards describing test methods for surface active agents. These were prepared, with the active participation of the UK, by Technical Committee 91, Surface active agents, of the International Organization for Standardization (ISO). In this Part of
10、BS 6829, Table 1 lists the Parts and Sections of BS 6829 and the analytical methods included therein and gives, if appropriate, their relationships to the corresponding International Standards. It is intended that work should continue with the object of improving existing test methods and preparing
11、others for publication as further Sections of BS 6829. This standard does not include methods of sampling surface active agents from bulk. Guidance in this respect is given, however, in BS 5309-1, BS 5309-3 and BS 5309-4. A British Standard does not purport to include all the necessary provisions of
12、 a contract. Users of British Standards are responsible for their correct application. 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, pages i and ii, pages 1 and 2, an inside
13、 back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

14、BSI BS 6829-0:1991 BSI 12-19991 1 Scope This Part of BS 6829 outlines, in Table 1, the present structure of BS 6829 and gives guidance on its use. NOTEThe titles of the publications referred to in this Standard are listed on the inside back cover. 2 Sampling For methods of sample division, see BS 37
15、62-1. 3 Reagents During the analysis, unless otherwise stated, use only reagents of recognized analytical grade and water complying with grade 3 of BS 3978. 4 Other methods In addition to the methods given in Table 1, other British Standard methods appropriate for the analysis of surface active agen
16、ts include method 1 of BS 3762-3.25 and BS 3900-A11.
