17、member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, govern

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenan

24、ductionSteel cord conveyor belts are mainly long belts which are manufactured by joining several delivery lengths on the site. To achieve joints with a high dynamic capability from belts supplied by various manufacturers, it is necessary to standardize some features, e.g. thickness of carcass or cor

31、lue 5 General remarksThe belt types described in this document are a selection out of the unlimited number of possible constructions; belts of the types A and B have been manufactured and installed in large quantities.It is the general conception of these belt types that belts of a certain nominal b

32、reaking strength have equal cords and cord pitches or at least equal thickness of the carcass.The requirements regarding belt design, i.e. cord diameter and cord pitch, depend on the mode of joint that will be applied. In accordance with ISO 15236-4, there are three types of vulcanized joints: inter

33、laced stepped joints; plain stepped joints; finger joints.For high performance stepped joints, it is essential that the belts to be joined have equal cord pitch and cord diameter. For belts to be joined by finger joints, the cord pitch and cord diameter are of less importance; what matters is a simi

34、lar thickness of the carcass. In Tables 2, 3, 4 and 5, therefore, cord diameter, cord pitch and number of cords are specified only for those types which are usually joined by stepped joints, i.e. belt types A1, A2 and B2.The cord numbers given in Tables 2, 3 and 5 are for guidance only. They result

35、from Formula (1):nKBFmin=Nbs1000(1)and from the requirement that the edge width shall be not larger than 40 mm and not smaller than 15 mm, i.e.15 bk 40A higher number of cords as well as a smaller number of cords can be applied provided that the requirements for minimum breaking strength specified i

36、n ISO 15236-1 and ISO 15236-4 are met. The belt breaking strengths are calculated by Formula (2):KFnBNbs=1000(2)For the purposes of this document, the symbols and units given in Table 1 apply.6 Belt types ABelt types A shall be manufactured with steel cords where the individual wires have been zinc

37、coated by a hot dip process. Requirements for belt types A1 and A2 shall be as given in Tables 2 and 3, respectively.NOTE Belt types A are designed for interlaced stepped belt joints with numbers of steps between 1 and 4. The t/d ratio of the A2 belt types is somewhat lower than that of the belt typ

38、es A1 resulting in thinner cords for comparable tensile strengths and in most cases a higher number of steps within the joint.Table 1 (continued)2 ISO 2017 All rights reservedBS EN ISO 15236-2:2017ISO 15236-2:2017(E)Table 2 Requirements for belt types A1Type of beltUnit 500 630 800 1 000 1 250 1 400
