8、of all three Parts. This revision includes additional products and is being published in three Parts as follows: Part1: Specification for sheeting, sheets and pillowslips 1) ; Part2: Specification for towels and napkins; Part3: Specification for counterpanes 1) . In this Part, which specifies the re
9、quirements for towels and napkins, the principal changes from the previous edition are: a) the addition of a second range of towels, identified by the reference TC which describes a range of towels of somewhat different construction from the original T series and which is sold in loomstate; b) a sli
10、ght change in T series towel dimensions to permit more efficient use of modern looms and with the object of improving production efficiency to the benefit of both producers and purchaser; c) the addition of a smaller size of babies terry napkin to accord with the growing use of this size in NHS hosp
11、itals. BS5815 covers only the basic description of the products and their construction and performance requirements. Purchasing authorities therefore may need to include additional information. This Part of BS5815 covers the end products quoted but can also be used to specify the fabric from which t
12、hey are manufactured. Many properties cannot be specified objectively and cannot therefore be included in this standard. Examples of such properties include colour, handle, appearance and details of additional design features. Public sector purchasing authorities may be able to supply standard patte
13、rns which cover these properties and serve to resolve any ambiguities of description. 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. Compliance with a British Standard does not of it
14、self confer immunity from legal obligations. In particular, attention is drawn to Statutory Instrument 1986 No.26, the Textile Products (Indications of Fibre Content) Regulations 1986. Summary of pages This document comprises a front cover, an inside front cover, pagesi and ii, pages1 to4, an inside
15、 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 theinside front cover. 1) In preparationBS5815-2:1988 BSI 03-1999 1 1 Scope This Part of BS5815 specifies the requirements for
