6、z f x w . c o m BS 5866-4:1991 ii BSI 07-1999 Foreword This Part of BS 5866 has been prepared under the direction of the Textiles and Clothing Standards Policy Committee. BS 5866 specifies requirements for a range of blanket types suitable for use in the public sector and is published in four Parts
7、as follows: Part 1: Specification for wool and wool/polyamide blankets; Part 2: Specification for cotton leno cellular blankets; Part 3: Specification for synthetic fibre cellular blankets; Part 4: Specification for flammability performance. In this Part, the flammability performance is specified, w
8、here required, for the range of blankets covered in Parts 1 to 3 of BS 5866. The requirements are based on the methods of test given in section 3 of BS 7175:1989. The Technical Committee responsible for the publication of BS 7175 has recommended that the assessment of flammability of individual item
9、s of bedcovers be carried out in the orientations that would be used in real-life situations, i.e. in both horizontal and vertical planes. It is important to note that test results relate only to the performance of the blankets under the particular condition of test and are not intended as a means o
10、f assessing the full potential fire hazard of a bed assembly. Attention is also drawn to the labelling requirements of clause 6. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compli
11、ance 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 back cover and a back cover. This standard has been updated (see copyright date) and may hav
12、e had amendments incorporated. This will be indicated in the amendment table on the inside front cover. w w w . b z f x w . c o m BS 5866-4:1991 BSI 07-19991 1 Scope This Part of BS 5866 specifies requirements for the flammability performance of the blankets specified in Parts 1, 2 and 3 of BS 5866,
13、 when tested in both horizontal and vertical positions in accordance with section 3 of BS 7175:1989. NOTEThe titles of the publications referred to in this Part of this British Standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS 5866 the definitions given
14、in BS 7175 and BS 6373 apply. 3 Sampling 3.1 Bulk sample Sampling shall be carried out in such a manner that samples taken are representative of the manufacturing, processing, or finishing batch from which they are drawn. A sampling scheme equivalent to at least two in every 3000 blankets shall be u
15、sed. 3.2 Test specimens 3.2.1 Smouldering cigarette test: ignition source 0 Where the smouldering cigarette test is to be performed, cut two test specimens from one finished blanket, such that the longer edge of each test specimen is the finished edge of the blanket, each test specimen being 1 350 m
16、m 450 mm. NOTEThis procedure ensures that, in the case of a cotton leno cellular blanket, at least one-third of each specimen, over its full length, will be of leno construction as opposed to plain weave. 3.2.2 Flaming ignition test: ignition source 5 Where the flaming ignition test is to be perform
17、ed, cut four specimens each 650 mm 650 mm. In the case of cellular blankets cut one specimen from each of the four corners of the blanket except that in the case of smaller blankets more than one blanket will be required to produce four specimens. Ensure that one finished edge of each specimen is in
18、 cellular weave and an adjacent finished edge is primarily in plain weave and partially in cellular weave. 4 Laundry procedure prior to testing Before conditioning and prior to testing in accordance with BS 7175, blankets shall be laundered using the appropriate procedure given in Table 1. NOTEThe f
19、lammability of a blanket may be affected by washing as a result of shrinkage, removal of finish (flame retardant or other), and by raising or compression of the surface pile. The washing procedures specified are appropriate for the type of blanket. It is assumed that the wool and synthetic blankets
20、will not be adversely affected by repeated washing and the number of wash cycles is therefore limited. Flame retardant cotton blankets are treated with a flame retardant finish and the large number of wash cycles specified ensures that the flammability performance will be retained for the normal was
