DIN EN ISO 20753:2014-07 EN ISO 20753:2014 (E) 3 Introduction Up to now, information on plastics test specimens has been specified in several different loca
39、tions: in test method standards (e.g. ISO 527-2), in ISO 3167 (for multipurpose test specimens) and in ISO 294-1, ISO 294-2, ISO 294-3 and ISO 294-5 (for moulding conditions). The aim of this International Standard is to give the designations and dimensions of test specimens used for the acquisition
40、 of comparable data, and also other frequently used specimens, in one document for ease of reference. This will be followed by a revision of the ISO 294 series, which will define only the injection-moulding conditions and will refer to this International Standard for the dimensions of the specimens.
41、 Other International Standards that have hitherto used different designations for the same specimen type will also be revised to bring the designations into line with those in this International Standard. DIN EN ISO 20753:2014-07 EN ISO 20753:2014 (E) 4 1 Scope 1.1 This International Standard specif
42、ies dimensional requirements relating to test specimens prepared from plastics materials intended for processing by moulding, as well as to test specimens prepared by machining from sheets or shaped articles. It gives, in one document, the designations and dimensions of test specimens used for the a
43、cquisition of comparable data and also other frequently used specimens. The following types of test specimen are specified: a) Type A1 and type A2 specimens (1 = injection moulded, 2 = machined from a sheet or shaped article) These are tensile test specimens from which, with simple machining, specim
44、ens for a variety of other tests can be taken (see Annex A). The type A1 specimen corresponds to the ISO 3167:2002 type A multipurpose test specimen. The principal advantage of a multipurpose test specimen is that it allows all the test methods mentioned in Annex A to be carried out by all test labo
45、ratories on the basis of comparable mouldings. Consequently, the properties measured are coherent as all are measured using similar specimens prepared in the same way. In other words, it can be expected that test results for a given set of specimens will not vary appreciably due to unintentionally d
46、ifferent 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 properties measured. Also described are reduced-scale test specimens designated type Axy, where x is the number
47、 indicating the method of specimen preparation (1 = injection moulded, 2 = machined from a sheet or shaped article) and y is a number indicating the scale factor (1:y). These can be used e.g. when full-sized test specimens are not convenient or when sample material exists in small quantities only. b
48、) Type B specimens These are bar specimens which can be directly moulded or can be machined from the central section of type A1 specimens or from sheets or shaped articles. c) Type C specimens These are small tensile test specimens which can be directly moulded or machined, e.g. from plates (Type D
49、specimens), from the central section of type A1 specimens or from sheets or shaped articles. d) Type D1 and type D2 specimens These are square plates of thickness 1 mm and 2 mm, respectively. If a particular type of test specimen is not mentioned in this International Standard, this does not mean that there is any intention to exclude the use of the specimen. Additi
