16、orldwide federation of national standards bodies (ISO 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
17、on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafte
18、d in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Stand
19、ard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21183-1 was prepared
20、by Technical Committee ISO/TC 41, Pulleys and belts (including veebelts), Subcommittee SC 3, Conveyor belts. This part of ISO 21183 is based on EN 873:1996, prepared by CEN/TC 188. ISO 21183 consists of the following parts, under the general title Light conveyor belts: Part 1: Principal characterist
21、ics and applications Part 2: List of equivalent terms EN ISO 21183-1:2006blank1Light conveyor belts Part 1: Principal characteristics and applications 1 Scope This part of ISO 21183 describes the principal characteristics and applications of light conveyor belts. This description is necessary either
22、 for limiting the validity of certain standards to light conveyor belts or for excluding light conveyor belts from the validity of certain standards. 2 Description 2.1 Applications 2.1.1 General applications Light conveyor belts are predominantly used for the indoor transport of unit loads (for exam
23、ple, parcels, boxes, cans, containers, luggage, industrial goods of all kinds and foodstuffs). In many cases, light conveyor belts are incorporated into a machine as an integral machine element. They are then called machine belts (also known as machine tapes). In that function, they perform either j
24、ust as a conveying element that additionally participates in a manufacturing action or in a manufacturing process. In such applications, machine belts sometimes get special names. EXAMPLE 1 Machines using machine belts with a pure conveying function: paper processing machinery (printing, cutting, et
25、c.), letter sorting/cancelling machines, ticket vending/defacing automats, packaging machines. EXAMPLE 2 Machines using machine belts participating in a manufacturing action or in a manufacturing process: newspaper folding machines, processing machinery for dough, chocolate and sweets, special proce
26、ssing machines for paper and plastic foil, cigarette manufacturing machines. EXAMPLE 3 Machine belts with special names: folder-gluer belts, tube-winder belts, printing blankets; processing belts in drying, coating, particle board manufacturing and other uses. 2.1.2 Other applications Bulk foods con
27、veying with light conveyor belts can be found in the chemical, pharmaceutical, cosmetic, food, agricultural, wood and tobacco industry. However they are almost always in indoor applications or outdoors under cover. EXAMPLE Granular or powdered materials, corn, rice, fruits, vegetables, wood chips, t
28、obacco. Outdoor applications of light conveyor belts are seldom encountered but are increasing for example, agricultural equipment, particularly some harvesting machines. EN ISO 21183-1:20062 2.2 Construction The tensile strength of light conveyor belts is normally provided by mainly synthetic fabri
29、c plies (polyamide, polyester, etc.) connected with each other either by bonding agents or by means of intermediate layers of different thickness, usually of thermoplastic material. The covers on both sides are function-related in material, thickness and texture. All combinations are possible, from
30、no coating via thin impregnation to thick coating and from ultra smooth to very rough surface. Coating materials may be thermoplasts (PVC, TPU, etc.), cross-linked synthetics (rubbers, PUR, etc.) and many others, all in very different hardness and other varieties of formulation. Highly specialized c
31、onstructions are found with machine belts very elastic belts, monolithic foils, surfaces with very high or low friction characteristics, etc. 2.3 Dimensions Light conveyor belts are almost exclusively manufactured in large widths (up to a few metres) and then are cut to any required dimension. The d
32、imensions of light conveyor belts are not standardized. Standardization would not be suitable as the light conveyor belts are predominantly used on non-standardized installations. The overall thicknesses vary from a few tenths of a millimetre to several millimetres, depending on the specific applica
33、tion (e.g. 10 mm or more in the case of light conveyor belts for the paper processing industry). The widths vary from about 10 mm (machine belts) to a few metres (processing belts). The lengths vary from about 500 mm to about 100 m. 2.4 Properties The ultimate tensile strengths vary from less than 1
34、00 N/mm of belt width to several hundred newtons per millimetre of belt width (e.g. to about 1 000 N/mm of belt width in highly specialized belt constructions with aramid fabrics). The maximum admissible working load is about 1/10 of the ultimate tensile strength. As mentioned in 2.2, the properties
35、 vary within a broad range and are function-related and, in the case of many types, are designed to meet highly specific application demands. EXAMPLE 1 Special light conveyor belts for the electronics industry have highly conductive covers with very small electric surface resistances and produce no
36、measurable electric field strength when running. These light conveyor belts are highly antistatic. EXAMPLE 2 Normal light conveyor belt covers are mostly insulators which usually generate high electric field strengths. Nevertheless, with some belts, no significant electric field strength is produced
37、 when the belt is running because of an electrically conductive layer inside the belt. These belts are antistatic in the sense of light conveyor belt technology.
