9、BSI 07-1999 Foreword This Part ofBS1425 has been prepared under the direction of the Textiles and Clothing Standards Policy Committee and, with Part2, forms a revision ofBS1425:1960, which will be withdrawn on a date to be announced. BS1425:1960 is referred to in The Rag Flock and Other Filling Mate

10、rials Regulations1981 and will not be withdrawn until those Regulations are revised. NOTEUpon publication of this revision, BSI Sales Department will respond to purchase orders for BS1425 by supplying copies of the 1991 edition. Copies of the 1960 edition may be obtained by quoting the number “BS142

11、5/60”. The other Part of BS1425 is Part2 “Specification for feather and/or down fillings and stuffings”. Due to the increasing awareness of the risk of fire, the Furniture and Furnishing (Fire Safety) Regulations became law from1March1989. These regulations require filling materials to be included i

12、n furniture and furnishings to comply with certain requirements for flame retardancy. However, the application of fire-retardant (FR) chemicals to those filling materials that are not naturally flame-retardant, may cause them to fail certain of the requirements inBS1425:1960 and thus prevents monito

13、ring of the cleanliness of FR treated materials. Therefore, a programme of work to establish a new testing regime was carried out jointly by the British Textile Technology Group and the Furniture Industry Research Association. In addition to facilitating differentiation between clean and “dirty” FR

14、treated filling materials, the opportunity has been taken to develop a more unified testing regime applicable to the wide range of materials used as fillings and stuffings. The main consideration underlying this revision of this standard is that the standard should serve to establish whether filling

15、s are hygienically clean and dust free. A microbiological cleanliness test has therefore been introduced. The remaining two test methods are for oil and dust measurement by determination of insoluble extract; these remain the same as inBS1425:1960. A significant part of the background to this approa

16、ch, implicit in the1960edition and also implicit in this revision, is the onus placed on the manufacturer or producer of any filling material to satisfy himself that his production is run consistently in a manner which would enable any sample to comply with this standard. This may be achieved either

17、 by a high degree of confidence based on experience or by a reliable means of quality control (based, for example, on sampling of current production, rapid testing and recording of test results on these samples) to ensure that the production line consistently meets considerably stricter limits than

18、those required by this standard. For that purpose, the basic problem of the manufacturer is to take samples from his current product and measure their properties at such intervals as will give adequate and timely warning of any failure to control production at the specified level of cleanliness. The

19、 frequency of sampling necessary for this will depend upon the uniformity of production (and for some fillings, of course, indirectly on the uniformity of the intake of raw materials). The method and frequency of sampling therefore cannot be specified in advance but should be determined by the manuf

20、acturer himself in the light of his own experience. Although the basic definitions of the various types of filling materials used inBS1425:1960 remain, the filling materials have been classified into three groups. These are used materials and materials of animal origin(3.1), new vegetable fibre fill

21、ings(3.2) and new synthetic filling materials(3.3). The processes of manufacture are no longer included.BS1425-1:1991 BSI 07-1999 iii Assessed capability. Users of this British Standard are advised to consider the desirability of assessment and registration of a suppliers quality systems against the

22、 appropriate Part ofBS5750 by a third party certification body. 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 itself confer immunity f

23、rom legal obligations. In particular, attention is drawn to The Rag Flock and Other Filling Materials Regulations 1981 SI No. 1218, to the Textile Products (Indications of Fibre Content) Regulations 1986 SI No.26 and subsequent amendments.

37、NOTEThe filling and stuffing materials listed in3.1, 3.2 and3.3 are examples only; the lists are not exhaustive. If the composition of a material is unknown, or is in question, identification may be carried out using the methods described in “Identification of Textile Materials” 1) , 7thedition publ

38、ished by The Textile Institute. 4 Sampling 4.1 Gross sample 4.1.1 General A gross sample of not lessthan0.5kg shall be taken. If the material is of such a nature that dust or short fibres become separated from the filling or stuffing material, a proportional amount by mass of such particles shall be

39、 included. The gross sample shall then be packed and sealed in a package, e.g.asampling envelope, and protected from adverse conditions, e.g.rain, for transport to the laboratory where the tests are to be carried out. NOTE 1It is recommended that gloves are worn when taking gross samples of material

40、s intended for bioburden testing. NOTE 2Gross samples of layered materials supplied in rolls should be taken in the form of strips cut across the full width of the roll together with any backing or inter-leaving material, which should remain with the filling material until it reaches the analyst. NO

41、TE 3A gross sample may be taken from a bulk stock or consignment of filling material or finished articles or, if necessary, it may be taken from any one bag, bale or other package or finished article. NOTE 4If the sample has been taken from only one bag, bale or other package, out of a considerable

42、number, this should be indicated. 4.1.2 Sampling of loose material For loose material, each gross sample shall be collected by taking at random, from atleast20places in the bulk, or in each bag, bale or other package selected for sampling, a number of separate fractions, each weighing approximately3

43、0g. When duplicate or triplicate samples are required, several samples shall be drawn at the same time and in the same manner, by taking two or three fractions from the same place or from adjacent places, placing each of them in a separate sample bag, and repeating this process until the two or thre

44、e gross samples are completed. NOTEWhen flocculent materials are being sampled, this is best achieved by taking one handful for each fraction and dividing it immediately and carefully between the two or three sample bags. No other procedure, such as taking one large gross sample and then dividing it

45、 into two or three, shall be used. 4.1.3 Sampling of layered material For layered material, each gross sample shall either be taken from a sufficient number of made-up pads or similar articles to make up the required sample mass, or shall be obtained by cutting strips, not less than300mm wide, acros

46、s the full width of the roll of the material. Backing or inter-leaving material shall not be disturbed and shall accompany the sample. When duplicate or triplicate samples are required, adjacent strips of material from a roll shall be used. NOTECareful cutting of the strips into portions is recommen

47、ded so that any variation due to layering can be reflected in each sample. If duplicate or triplicate samples are obtained by cutting two or three adjacent strips across a roll, each strip shall be cut into twice as many pieces as the number of samples required, as shown in Figure 1. The first gross

48、 sample shall comprise all the pieces numbered (1), the second sample shall comprise all the pieces numbered (2), etc. 4.2 Preparation of test specimens Test specimens shall be taken from the gross sample in such a manner as to ensure that each test specimen is representative of the gross sample, as

49、 follows. Carefully open the parcel containing the sample and, after removing from layered materials any backing or inter-leaving material, arrange the whole of the sample on a sampling table. Divide the gross sample, whether it is loose or layered material, into20piles or heaps approximately equal in bulk. Take small quantities of material from each of the20piles or heaps. In the case of any material from which short fibres or dust fall readily, include a proportional amount by mass of any short fibres and dust in each test specimen. 1) Available from The Textile Institu
