6、 back coverBS6829-0:1991 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 It is a revision of the1989 edition of BS6829-0, which is withdrawn. BS6829 provides a series of analytical methods for surface active agents used
7、in their unbuilt form or used as raw materials for formulated products. BS 6829 is published in six Parts, the analytical methods in Parts1 to5 being published separately as Sections. In preparing this British Standard, the opportunity was taken, if appropriate, of implementing, preferably without a
8、lteration, International Standards describing test methods for surface active agents. These were prepared, with the active participation of the UK, by Technical Committee91, Surface active agents, of the International Organization for Standardization (ISO). In this Part of BS6829,Table 1 lists the P
9、arts and Sections of BS6829 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 others for publication as fur
10、ther Sections of BS6829. This standard does not include methods of sampling surface active agents from bulk. Guidance in this respect is given, however, in BS5309-1, BS 5309-3 and BS5309-4. A British Standard does not purport to include all the necessary provisions of a contract. Users of British St
11、andards 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, pagesi andii, pages1 and2, an inside back cover and a back cover. This s
12、tandard 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.BS6829-0:1991 BSI 12-1999 1 1 Scope This Part of BS6829 outlines, inTable 1, the present structure of BS6829 and gives guidance on its use.
13、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 BS3762-1. 3 Reagents During the analysis, unless otherwise stated, use only reagents of recognized analytical grade and water complying with grade3 of B
14、S3978. 4 Other methods In addition to the methods given inTable 1, other British Standard methods appropriate for the analysis of surface active agents include method1 of BS3762-3.25 and BS3900-A11.
