To maintain their curre
4、ncy, all Standards are periodically reviewed, and new editions are published. Between editions, amendments may be issued. Standards may also be withdrawn. It is important that readers assure themselves they are using a current Standard, which should include any amendments which may have been publish

Detailed information about Standards can be found by visiting the Standards Australia web site at .au and looking up the relevant Standard in the on-line catalogue. Alternatively, the printed Catalogue provides information current at 1 January each year, and the
6、monthly magazine, The Australian Standard, has a full listing of revisions and amendments published each month.

10、eyor beltingTextile reinforced. This Standard was first published as part of the B-Mechanical Engineering series, being AS B3 published in 1929, with a second edition in 1944. AS B6 was first published in 1933 and revised in 1936 (both Standards being British Standards BS 490 of 1933, endorsed with
11、Australian amendments). It was revised in 1966 and redesignated as AS B6.1. AS B3 of 1944 and AS B6.1 of 1966 were amalgamated to become AS 1331 of 1974. This Standard was amalgamated with AS 1332 of 1974 (first published as AS B6.2 of 1969) and published as AS 1332 of 1982. The third edition was pu
12、blished in 1984, and the fourth edition in 1991. The objective of this revision is to separate the fire resistant and antistatic requirements of Grade S belting from this Standard. These requirements are specified in AS 4606, Fire resistant and antistatic requirements for conveyor belting used in un
13、derground coal mines with a view to meeting the requirements of the N.S.W. Government relating to the administration of the Coal Mines Regulation Act. Requirements such as those for impact resistance, resistance to gouging, tensile fatigue, flexing and coefficient of friction are yet to be considere
14、d, pending development of suitable test methods. The main difference between this Standard and the 1991 edition is that requirements for fire-resistant and antistatic properties are no longer included, and Table 7 has been altered. The term informative has been used in this Standard to define the ap
15、plication of the appendix to which it applies. An informative appendix is only for information and guidance.

29、our A, E, M, N Blue F, S White Z Other than blue or white Where the use of a belt requires certification, any splicing materials used shall also be certified. NOTE: Certification may be required by certain regulatory bodies. 3.3 Belt fabric/cord Belt fabric/cord is classified according to the follow
30、ing code letters depending on fibres used in the warp and weft direction: Fabric/cord Code letter Corresponding DIN 22102.1 code letter* Cotton Nylon (Polyamide) Polyester Glass Aramid (Polyaramide) Vinylon Rayon C N P G A V R B P E G D Z or R * For reference purposes only, and does not form part of
31、 the Standard. Commonly known as Kuralon in the industry. NOTE: In woven fabric, the warp material represents the first letter or group of letters and the weft the second letter or group of letters, e.g. PN would have a polyester warp and a nylon weft. In the case of mixed material in either warp or
32、 weft (or both), the greater strength fibre would have an upper-case letter and the lower strength fibre would have a lower- case letter, e.g. PcN would be polyester/cotton warp and nylon weft. In case of ambiguity, a space or should be used between the warp and weft letters or groups of letters. 3.
33、4 Designation The designation of the belting shall be by the number of this Australian Standard followed by the belt carcass designation and cover grade. (See Clause 7.) 4 CONSTRUCTION 4.1 Belting Belting shall consist of a textile carcass impregnated with one or more elastomeric or other (e.g. poly
34、vinyl chloride) compounds. Covers, where present, shall be applied to the carcass and meet the requirements of Clause 4.3. The Standard is downloaded from Standard Sharing AS 13322000 .au Standards Australia 7 4.2 Textile carcass 4.2.1 General The textile carcass shall consist of one or more essent
35、ially parallel plies (the number designated n in Table 5) of fabric or cord reinforcement. The reinforcement shall consist of natural or synthetic fibres (or both). It shall be evenly and firmly laid or woven and be free from foreign matter and defects such as knots, lumps and irregularities of twis
36、t. The construction of plied belting shall be either full width ply or stepped ply. NOTES: 1 The defects described cannot be completely quantified. Where the presence, size or frequency of any of these are considered to be of concern, arrangements should be made between the purchaser/regulatory auth
37、ority/certifying body (as appropriate) and the manufacturer. This may be achieved by the provision of acceptable type samples or methods of test. Where defects are present and the product is submitted for acceptance, the manufacturer should be able to demonstrate fitness for purpose. 2 Ply joints ar
38、e not recommended in one-ply and two-ply belts. 4.2.2 Transverse ply joints Transverse ply joints shall be not less than 15 m from the ends of the belt, and at an angle between 40 degrees and 50 degrees from the longitudinal axis. The gap between ply ends in such joints shall be not greater than 10
39、mm, nor shall plies be overlapped. The distance between transverse joints shall be as follows: (a) The joints in adjacent plies shall be not less than 3 m apart. (b) The joints in non-adjacent plies shall be not closer than the width of the belting. (c) Where two plies or one ply and a portion of an
40、other ply are formed by folding the fabric at the edges, the joints in the fabric used shall be not less than 3 m apart. (d) In outer plies, the joints in the same ply shall be not less than 100 m apart. (e) In inner plies, the joints in the same ply shall be not less than 15 m apart and not more th
41、an two such joints shall be in any ply in each 100 m of belting. 4.2.3 Longitudinal ply joints 4.2.3.1 Spacing of joints The spacing of longitudinal ply joints shall comply with the following requirements: (a) Joints shall be not less than 100 mm from the edge of the carcass. (b) A joint shall not l
42、ess than 100 mm from any longitudinal joint in other plies. (c) The joints in one ply shall be separated by not less than 300 mm where the width of the belting permits two joints in the same ply. (d) Multiple joints in a belt shall be balanced about the centre-line. (e) There shall be no open gaps b
43、etween the edges of plies greater than 10 mm wide even if filled with impregnating material, nor shall the plies overlap. NOTE: Where the configuration of idlers is known, longitudinal joints should be arranged so as to avoid coinciding with the zone at which the troughing angle changes. 4.2.3.2 Num
44、ber of joints Where the reinforcement consists of three or more plies, the maximum permissible number of longitudinal joints in any one ply shall be as specified in Table 1. NOTE: In belting required to be slit, there should be no longitudinal joints up to and including 1600 mm in width. AS 13322000

46、cass protection Covers shall consist of flexible elastomeric or other (e.g. polyvinyl chloride) compounds. When required for the purpose of secondary carcass protection, a layer of open mesh- breaker or breaker-fabric may be incorporated in the cover. Where incorporated, the open mesh breaker or bre
47、aker-fabric shall be included in the cover thickness, provided, however, that such a layer shall not be included in the cover thickness for the purposes of determining tensile strength of covers (see Clause 6.3) nor shall it be counted as one of the fabric plies. NOTE: The purchaser should specify i
48、f secondary carcass protection is required (see Appendix B, Paragraph B2(i). 4.4 Freedom from defects The belting shall be free from visual defects known to impair its serviceability. 5 DIMENSIONS AND TOLERANCES 5.1 Length The length of belting and the tolerances thereon shall be in accordance with
49、the following requirements: (a) The length of belting shall be free from factory-made splices. NOTE: This requirement may be waived by the purchaser so that a single splice is permitted (see Appendix B, Paragraph B2(j). (b) When measured in accordance with AS 1334.1, the length of belting required by the purchaser in the endless form
