11、ulating materials. It supersedes the 1969 edition which is withdrawn. The four classification groups of materials, similar to those specified in the 1969 edition, have been retained although in this revision the basis of the classification is that of thermal conductivity, not of density. Thermal con
12、ductivity values have been reviewed and generally improved. The format and presentation of this revision has also been aligned with other recently published Parts of this standard. Other Parts of BS 3958 are: Part 1: Magnesia preformed insulation; Part 2: Calcium silicate preformed insulation; Part
13、3: Metal mesh faced man-made mineral fibre mattresses; Part 4: Bonded preformed man-made mineral fibre pipe sections; Part 6: Finishing materials; hard setting composition, self-setting cement and gypsum plaster. A British Standard does not purport to include all the necessary provisions of a contra
14、ct. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This will be indicated in the amendment table on theinside front cover.BS3958-5:1986 BSI 07-1999 1 1 Scope This Part of BS 3958 specifies composition, moisture content, physical and chemica
16、l requirements, and sizes for bonded man-made mineral fibre slabs for thermal insulating purposes. The material is classified into four groups according to its thermal conductivity and temperature range. Information to be supplied when ordering is given in Appendix A. This standard is not intended t
17、o cover materials used to insulate the fabric of buildings. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this Part of BS 3958, the definitions given in BS874, BS 2972 and BS 3533 apply. 3 Sampling and testing S
18、ampling and testing shall be in accordance with the appropriate clause in BS 2972. Slabs shall be tested without an applied finish. 4 Composition The insulation material shall be of man-made mineral fibre made from rock, slag or glass, processed from a molten state into a fibrous form, and shall be
19、bonded together with a suitable thermosetting binder to form slabs. Slabs shall not contain non-fibrous pieces of these materials that have any dimension exceeding10mm. 5 Moisture content When conditioned at high humidity in accordance with 40.4 of BS 2972:1975, the moisture content of the material
20、shall not exceed 5% by mass. 6 Physical requirements 6.1 Thermal conductivity When tested in accordance with the appropriate method of test for thermal conductivity given in BS874 with a cold face not exceeding 50 C, the measured thermal conductivity shall not exceed the values given in Table 1, for
21、 the appropriate group. Table 1 Thermal conductivity values Some products in a given thermal conductivity group may not, therefore, be capable of being used over the full temperature range indicated in Table 1 and the limiting temperature declared by the manufacturer shall be observed (see 6.4). Som
22、e products may be capable of exceeding the temperature range indicated in Table 1. In this case the manufacturer shall declare values of thermal conductivity at these higher temperatures. NOTEThe groups given in Table 1 are based on thermal conductivity values only. They are not density groups. Howe
23、ver, for general guidance the density ranges associated with these thermal conductivity groups are usually as follows: a) group 1: 15 kg/m 3to 50 kg/m 3 ; b) group 2: 30 kg/m 3to 80 kg/m 3 ; c) group 3: 50 kg/m 3to 160 kg/m 3 ; d) group 4: 140 kg/m 3to 300 kg/m 3 . 6.2 Bulk density For any particula
24、r product, the variation from the manufacturers declared value for bulk density, calculated at the nominal thickness and determined on full-size slabs shall not exceed 15 %. NOTEThe bulk density of the material will normally lie within the range 15 kg/m 3to 300 kg/m 3 . Materials of each group are m
