14、d in the other parts of ISO 3597. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 3597. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties
15、 to agreements based on this part of ISO 3597 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards. ISO 291:1977, Plastics Standard atmospheres for con
16、ditioning and testing. ISO 7822:1990, Textile glass reinforced plastics Determination of void content Loss on ignition, mechanical disintegration and statistical counting methods. 3 Principles The testing methods briefly described hereafter are generally performed on as-made rods. They may however,
17、also be carried out on rods which have been submitted to a boiling water pretreatment for a specified time. The preparation of rods as detailed in clause 5 includes the manufacture and division of rods into specimens of given length and their treatment in boiling water, if such treatment is required
18、. In order to obtain consistent results, conditions for the preparation of the rods (resin mixture, impregnation system and pulling speed, cure conditions, etc.) shall be as uniform as possible. Furthermore, if the roving specification requires that the void content of rods to be tested shall be wit
19、hin given limits, this characteristic shall be determined in accordance with ISO 7822. 3.1 Determination of flexural strength The specimen is laid horizontally on two supports and deformed at constant speed by applying a stress at midspan, until the specimen breaks or until the strain has reached a
20、predetermined level. The flexural strength of the specimen, expressed in megapascals, is the stress measured at that moment. 3.2 Determination of compressive strength The specimen is axially compressed by applying a stress on the flanges at constant speed until the specimen breaks or until the defor
21、mation has reached a predetermined level. The compressive strength of the specimen, expressed in megapascals, is the stress measured at that moment. 3.3 Determination of apparent interlaminar shear strength A simple flexural test is carried out as described in 3.1 on a specimen, using however a span
22、 shorter than that used for the standard flexural test. The apparent interlaminar shear strength of the specimen, expressed in megapascals, is the stress measured at failure or the maximum stress that is reached in the test. 4 Conditioning and testing atmospheres The atmosphere required for conditio
23、ning and for testing the specimens is specified in ISO 291. 5 Preparation of the test specimens 5.1 Apparatus and material 5.1.1 Mould, in the form of a rigid cylinder having a minimum length of 300 mm and a standard internal diameter of 4 mm 0,1 mm (for flexural and interlaminar shear strength test
24、s) or 6 mm 0,1 mm (for compression test). If other diameters are chosen, these shall be selected by agreement between the interested parties from the range of 3 mm to 10 mm (with tolerances of 0,1 mm). It is highly recommended however that the standard diameter be chosen, since the use of different
