9、BS 2782 Methods of testing plastics: Part 3: Mechanical properties, as Method 326E:1996. EN 527-3:1995 was produced as a result of international discussions in which the United Kingdom took an active part.

10、It has been implemented to enable experience of the method to be gained and for use for other fresh applications. It is also for use for the revision or amendment of other national standards as practicable, but it should not be presumed to apply to any existing standard or specification which contai

This British Standard, which is identical with EN ISO 527-3:1995, does not necessarily detail all the precautions necessary to meet the requirements of the Health and Safety at Work etc. Act 1974.

This European Standard shall be given the status of a national standard, either by public

23、ation of an identical text or by endorsement, at the latest by February 1996, and conflicting national standards shall be withdrawn at the latest by February 1996. In accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard: Austria,

24、 Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.EN ISO 527-3:1995 BSI 16 March 2004 3 1 Scope 1.1 This part of ISO 527 specifies the conditions for determining the tensile prope

25、rties of plastic films or sheets less than 1 mm thick, based upon the general principles given in part 1. NOTE For sheets greater than 1 mm thick, the user is referred to part 2 of this International Standard. 1.2 See ISO 527-1, subclause 1.2. 1.3 This part of ISO 527 is not normally suitable for de

26、termining the tensile properties of: a) cellular materials; b) plastics reinforced by textile fibres. 1.4 See ISO 527-1, subclause 1.5. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 527. At the time

27、of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO 527 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain regis

28、ters of currently valid International Standards. ISO 527-1:1993, Plastics Determination of tensile properties Part 1: General principles. ISO 4591:1992, Plastics Film and sheeting Determination of average thickness of a sample, and average thickness and yield of a roll by gravimetric techniques (gra

29、vimetric thickness). ISO 4593:1993, Plastics Film and sheeting Determination of thickness by mechanical scanning. 3 Principle See ISO 527-1, Clause 3. 4 Definitions See ISO 527-1, Clause 4. 5 Apparatus See ISO 527-1, Clause 5, subject to the following additional requirements: In 5.1.2, the tensile-t

30、esting machine shall be capable of maintaining the speeds of testing as specified in Table 1 of ISO 527-1. It is normal for films and sheets to be tested at a speed of 5 mm/min, 50 mm/min, 100 mm/min, 200 mm/min, 300 mm/min or 500 mm/min. The information contained in ISO 527-1, subclause 9.6, also a

31、pplies. In 5.1.5, when testing thin sheets or film material, the specimen shall not carry the weight of the extensometer. In 5.2, devices complying with the requirements in ISO 4593 shall be used for measuring the thickness, except in the case of very thin film (less than 0,01 mm thick) or embossed

32、film. In those cases, the thickness shall be determined by the method specified in ISO 4591. When ISO 4591 is used, the average thickness of the film sample shall be taken as the thickness of the test specimen.EN ISO 527-3:1995 4 BSI 16 March 2004 6 Test specimens 6.1 Shape and dimensions 6.1.1 The

33、preferred form of test specimen for the determination of tensile properties by this method is a strip 10 mm to 25 mm wide and not less than 150 mm long (specimen type 2 see Figure 1), having two parallel gauge marks, 50 mm apart, on the central portion of the specimen. Some film materials have a ver

34、y high elongation at break which may result in them being outside the stretching capacity of the testing machine. In such cases, it is permissible to reduce the initial distance between the grips to 50 mm. 6.1.2 When required by the specification for the material under test or for routine quality-co

35、ntrol tests, dumb-bell specimen types 5, 1B and 4 of the shape and dimensions shown in Figure 2, Figure 3 and Figure 4 may be used. These specimens are convenient to produce and permit rapid quality-control testing. Specimen type 5 (Figure 2) is recommended for film and sheet with a very high strain

36、 at break. Specimen type 4 is recommended for other types of flexible thermoplastic sheet. Specimen type 1B (Figure 3) is recommended for rigid sheets.

39、fier is recommended to check the absence of notches. Razor blades, suitable paper cutters, scalpels or other devices capable of cutting the specimens to the proper width and producing straight, clean, parallel edges with no visible imperfections shall be used. Punch dies shall be kept sharp by regul

40、ar honing, and a suitable backing material shall be used with punch dies to ensure a clean-cut edge. 98 mm 6.2.2 The test specimens described in 6.1.2 shall be obtained by the use of punch dies, using suitable backing material to ensure a clean-cut edge. Dies shall be kept sharp by regular honing, a

41、nd the edges of the specimen shall be examined with a low-power magnifier to ensure the absence of notches. Discard any specimen with obvious imperfections on the cut edges. 6.3 Gauge marks See ISO 527-1, subclause 6.3. The marking device used to produce the gauge marks shall have two parallel edges

42、 which are ground smooth and true, 0,05 mm to 0,10 mm wide at the edge and bevelled at an angle of not more than 15 . An ink stamp may also be used to apply ink to the area of the gauge marks, before or after producing them with the marking device, using an ink of a suitable contrasting colour that

43、has no deleterious effect on the film being tested. 6.4 Checking the specimens Discard any test specimen with obvious imperfections on the cut edges. 6.5 Anisotropy The properties of certain types of film material may vary with direction in the plane of the film (anisotropy). In such cases, it is es

44、sential to prepare two groups of test specimens with their major axes respectively parallel and perpendicular to the direction of orientation of the film.
