The work of preparing International Standards is normally

18、 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, governmental and non-governmental, in liaison with ISO, also take part in the w

19、ork. 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 maintenance are described in the ISO/IEC Directives, Part 1. In particular the dif

20、ferent approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document m

24、) which was withdrawn in 2013.ISO 3167 is intended to be gradually replaced by ISO 20753 which specifies the designations and dimensions of test specimens used for the acquisition of comparable data, and also other frequently used specimens, in one document for ease of reference.iv ISO 2014 All righ

25、ts reservedBS EN ISO 3167:2014INTERNATIONAL STANDARD ISO 3167:2014(E)Plastics Multipurpose test specimens1 ScopeThis International Standard specifies requirements relating to multipurpose test specimens for plastic moulding materials intended for processing by injection or direct compression mouldin

26、g.Specimens of types A and B are tensile test specimens from which, with simple machining, specimens for a variety of other tests can be taken (see Annex A). Because they have such wide utility, these tensile specimens are referred to in this International Standard as multipurpose test specimens.The

27、 principal advantage of a multipurpose test specimen is that it allows all the test methods mentioned in Annex A to be carried out on the basis of comparable mouldings. Consequently, the properties measured are coherent as all are measured with specimens in the same state. In other words, it can be

28、expected that test results for a given set of specimens will not vary appreciably due to unintentionally different moulding conditions. On the other hand, if desired, the influence of moulding conditions and/or different states of the specimens can be assessed without difficulty for all of the prope

29、rties measured.For quality-control purposes, the multipurpose test specimen can serve as a convenient source of further specimens not readily available. Furthermore, the fact that only one mould is required may be advantageous.The use of multipurpose test specimens is to be agreed upon by the intere

30、sted parties, because there may be significant differences between properties of the multipurpose test specimens and those specified in the relevant test methods.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for

For some materials, the length of the tabs may need to be extended (e.g. to give an overall length of 200 mm) to prevent breakage or slippage in the jaws of the test machine.bThe recommended

37、 values and ranges may become mandatory on occasion of the next revision of the standard. The lower tolerances on the radius reduce the ranges of the stress concentrations that are found at the transitions between the narrow parallel-sided and the rounded portions. Together with the smaller toleranc

38、e on the distance between the broad parallel-sided portions for type B, a common value of the initial distance between jaws can be used for tensile testing (see ISO 527-2).crll bbbb=()+()()212212214dResulting from l1, r, b1and b2, but within the indicated tolerance.Figure 1 Type A and B multipurpose

39、 test specimens4 Preparation of test specimen4.1 GeneralTest specimens shall be prepared in accordance with the relevant material specification. When none exists, specimens shall be either directly compression or injection moulded from the material in accordance with ISO 293, ISO 294-1, ISO 295 or I

40、SO 10724-1, as appropriate, or machined in accordance with ISO 2818 from plates that have been compression or injection moulded from the compound.Strict control of all conditions of the specimen preparation is essential to ensure that all test specimens in a set are actually in the same state.2 ISO

41、2014 All rights reservedBS EN ISO 3167:2014ISO 3167:2014(E)All surfaces of the test specimens shall be free from visible flaws, scratches or other imperfections. With moulded specimens all flash, if present, shall be removed, taking care not to damage the moulded surface.The broad sides of each spec

42、imen shall be suitably marked (see the note), for injection-moulded specimens to distinguish between the sides formed by the cavity plate and the fixed plate of the mould (see ISO 294-1 or ISO 10724-1), for compression-moulded and machined specimens to identify any asymmetry resulting from the under

43、lying moulding process.NOTE Asymmetry with respect to thickness can influence the flexural properties, including the temperature of deflection under load (see Annex A).For injection-moulded specimens, the sides can be identified by the impressions of the ejection pins and by the draft angle. Compres

44、sion-moulded and machined specimens shall be marked at their shoulders. ISO bars taken from the central part of multipurpose test specimens shall be marked outside their central 40 mm section, which is loaded by flexural testing.4.2 Injection moulding of multipurpose test specimensType A test specim

45、ens shall be injection moulded as specified in ISO 294-1 or ISO 10724-1, as appropriate, and under conditions defined in the relevant International Standard for the material under examination.4.3 Compression moulding of multipurpose test specimensType B test specimens shall be compression moulded di

46、rectly to their final dimensions as specified in ISO 293 or ISO 295, as appropriate, and under conditions defined in the relevant International Standard for the material under examination.4.4 Machining of multipurpose test specimens4.4.1 Machining of test specimens shall be performed either as speci

47、fied in ISO 2818 or as agreed upon by the interested parties.4.4.2 Test specimens having a width of 10 mm shall be cut symmetrically from the central parallel-sided portion of the multipurpose test specimen.The surface of the central parallel-sided portion of the test specimen shall remain as moulde

48、d: The width of the machined portions of the specimen shall be not less than that of the central parallel-sided portion, but may exceed the width of the latter by not more than 0,2 mm. During the machining operation, care shall be taken to avoid any damage to the moulded surfaces of the central port

49、ion.For test specimens longer than 80 mm, the broad ends of the type A multipurpose test specimen (or type B for test specimens longer than 60 mm) shall be machined to the width of the central parallel-sided portion.4.4.3 Type B multipurpose test specimens shall be machined from suitably processed compression-moulded plates (see 4.3).5 Report on preparation of test specimensThe report shall contain the following information:a) a reference to this International Standard;b) an indication of the specimen type (A or B); ISO
