3、 permitted without license from IHS -,-,- IS0 1163-1:1995(E) Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical commi
4、ttees 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, governmental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the In
5、ternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member
6、 bodies casting a vote. lnternational Standard IS0 1163-l was prepared by Technical Committee lSO/rC 61, Plastics, Subcommittee SC 9, Thermoplastic materials. This third edition cancels and replaces the second edition (IS0 1163-1.1985), which has been technically revised The main changes concern the

11、 1 Scope 1.1 This part of IS0 1163 establishes a system of designation for unplasticized PVC thermoplastic material which may be used as the basis for specifications. 1.2 The types of PVC-U plastics are differentiated from each other by a classification system based on appro- priate levels of the de
12、signatory properties a) Vicat softening temperature b) impact strength (Charpy notched) c) modulus of elasticity and on information about basic polymer parameters, intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials. 1.3 Thi
13、s part of IS0 1163 is applicable to all unplasticized compositions of homopolymers and copolymers that contain at least 50 % (m/m) of vinyl chloride. It is also applicable to compositions containing chlorinated poly(vinyl chloride) and to compositions containing blends of one or more of the above-me
14、ntioned polymers, provided that the total amount of these polymers represents at least 50 % (m/m) of the polymer content of the composition It applies to materials ready for normal use in the form of powder, granules or pellets and to materials unmodified or modified by colorants, additives, fillers
15、, etc. This part of IS0 1163 does not apply to cellular plastics. 1.4 It is not intended to imply that materials having the same designation give necessarily the same perform- ance. This part of IS0 1163 does not provide engineering data, performance data or data on processing conditions which may b
16、e required to specify a material for a particular application and/or method or processing. If such additional properties are required, they may be determined in accordance with the test methods specified in part 2 of this International Standard, if suitable. 1.5 In order to specify a thermoplastic m
17、aterial for a particular application or to ensure reproducible processing, additional requirements may be given in data block 5 (see clause 3, introductory paragraph).

For unambiguous coding, the individual-item block is sub
23、divided into 5 data blocks comprising the following information: Data block 1: Data block 2: Identification of the plastic by its symbol PVC-U in accordance with IS0 1043-I (see 3.1) Position 1: Intended application or method of processing (see 3.2) Positions 2 to 8: Important properties, additives
