27、ernational Standard includes the determination of physical properties of both “low grammage” sheets and “high grammage” sheets, prepared in accordance with ISO 5269-1, ISO 5269-2 or ISO 5269-3. The oven-dry grammage of the “low grammage” sheets is (60 2) g/m2using the conventional sheet former, as d
28、escribed in ISO 5269-1 and ISO 5269-3, or (75 2) g/m2using the Rapid-Kthen sheet former, as described in ISO 5269-2 and ISO 5269-3. The oven-dry grammage of the “high grammage” sheets is 140 g/m2, with a tolerance of 3 % using the conventional and the Rapid Kthen sheet formers, except for the z-dire
29、ctional tensile strength where the grammage is 90 g/m2.For determination of physical properties, ISO 5270 refers to the relevant International Standards for paper and board for the description and calibration of the required equipment, and for the calculation and reporting of results. This Internati
30、onal Standard, however, specifies the procedures for testing laboratory sheets where the amount of material is limited, compared to testing of paper and board to which the relevant International Standards referred to are applicable, and for that reason there may be a discrepancy.4DIN EN ISO 5270:201
31、3-02 EN ISO 5270:2012 (E) 1 ScopeThis International Standard specifies the relevant International Standards to be used for the determination of physical properties of laboratory sheets made of all kind of pulps. It is applicable to laboratory sheets prepared in accordance with ISO 5269-1, ISO 5269-2
32、 or ISO 5269-3.In this International Standard, it is left to the pulp producer and the pulp user to agree upon which properties are relevant to be tested. The results are, if applicable, reported in index form.2 Normative referencesThe following referenced documents are indispensable for the applica

40、l Standard, ISO 153611, has been published for pulps describing the determination of zero-span tensile strength, wet or dry.3 PrincipleDetermination of physical properties of laboratory sheets using the procedure and equipment described in the relevant International Standards given in Tables 1 and 2
41、. The results are, if applicable, reported in index form.NOTE The properties to be measured are jointly determined by the pulp producer and the pulp user.4 ApparatusThe equipment is specified in the respective International Standards given in Tables 1 and 2 to which this International Standard refer
42、s. The equipment shall be calibrated in accordance with the instructions in the relevant International Standards given in Tables 1 and 2.5 Trimmed laboratory sheets5.1 Selection of laboratory sheetsDepending on the properties to be tested, determine the number of laboratory sheets required (see Tabl
43、e 1 and/or Table 2). The specification of the number of test pieces needed for each property defines the area required for testing and thus the number of sheets.Each sheet shall be free of visible defects.5.2 Conditioning of laboratory sheetsCondition the laboratory sheets in the standard atmosphere
44、 (23 1) C and (50 2) % relative humidity, or in the atmosphere allowed in tropical countries, according to ISO 187.ISO 187 states in its Introduction that “Unless otherwise specified, the equilibrium condition should be attained by the sorptive process”. For tests in which the hysterisis of the equi
45、librium moisture content may lead to important errors, the sample shall be pre-conditioned before conditioning (see ISO 187:1990, 6.1). If it is known that conditioning will result in an equilibrium moisture content equivalent to that achieved by sorption, the pre-conditioning may be omitted.If the
46、laboratory sheets have been prepared using the conventional sheet former, according to ISO 5269-1 or ISO 5269-3, the sheets may reach equilibrium by desorption. If the laboratory sheets have been prepared using the Rapid-Kthen sheet former, according to ISO 5269-2 or ISO 5269-3, the sheets may reach
47、 equilibrium by sorption of moisture.Whenever the test atmosphere is known to have been outside the limits and there is any chance that the moisture content of the sheets has been changed by such excursions, all sheets must be reconditioned before any further testing (see ISO 187).Keep the laborator
48、y sheets in the conditioning atmosphere until testing is completed.NOTE 1 Pre-conditioning using heat may change the optical properties and is, for that reason, not recommended for the sheets to be used for measuring optical properties.NOTE 2 It is not recommended to use the Rapid-Kthen sheet former
49、, described in ISO 5269-2 and ISO 5269-3, for preparation of laboratory sheets intended for determination of optical properties, since the high temperature used when drying the sheets may change the optical properties.6DIN EN ISO 5270:2013-02 EN ISO 5270:2012 (E) NOTE 3 The moisture content and thus physical properties of laboratory sheets at a given relative humidity (e.g. a
