19、Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 07 05:39:47 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 963:1995 BSI 08-19993 0 Introduction Geotextiles and geotextile-related products are producted in many different ways, partly using traditional textile procedures, partly using procedures no
20、t commonly recognized as textile procedures. Geotextiles and geotextile-related products are used in engineering, building, construction, hydraulic works etc. Geotextiles and geotextile-related products are typically supplied in rolls. Whilst sampling should ensure the best possible statistical sign
21、ificance of the average finding and its coefficient of variation, there are practical limits to the possible distribution of samples and specimens over the entire lot and its single units supplied to a construction site. 1 Scope 1.1 This European Standard establishes general principles for sampling
22、of geotextiles and geotextile-related products and preparation of test specimens from the samples. 1.2 The sampling principles are applicable to geotextiles and geotextile-related products supplied in rolls to construction sites. NOTEEN 20186 may be used for products supplied in other forms. 1.3 The
23、 specimen preparation principles are applicable to all geotextiles and geotextile-related products. 2 Normative reference This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text
24、and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incoporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.
25、EN 20186:1995, Paper and board Sampling to determine average quality. (ISO 186:1985) 3 Procedure 3.1 Sampling 3.1.1 Selection of rolls 3.1.1.1 For each product type delivered to a construction site, take samples at frequencies agreed between the parties involved. NOTERecommended frequencies are show
26、n in Table 1. Table 1 Frequencies of sampling 3.1.1.2 With the exception of tests in connection with claims the roll from which the sample is selected shall appear undamaged and the wrapping, if any, shall be intact. 3.1.2 Cutting 3.1.2.1 Information regarding the number of test specimens, their sha
27、pe and any requirements shall be obtained from the relevant test standard(s) for all tests to be made on the sample. 3.1.2.2 The first two turns of the roll shall not be used for sampling. 3.1.2.3 Cut from the roll over its full width perpendicular to the machine direction (production direction roll
28、 length direction) the length of the sample necessary to obtain all specimens required, distributed in accordance with the principles in this European Standard (see 3.2). 3.1.2.4 As the specimens shall not contain dirt, irregular areas, creases, holes or other damaged parts (see 3.2.2), such section
29、s shall be avoided by the sampling (except for 3.1.1.2). 3.1.3 Identification 3.1.3.1 When the two faces of the geotextile or the geotextile-related product are significantly different the sample shall be marked to show which face was inside or outside the turn of the roll. 3.1.3.2 Another mark (e.g
30、. an arrow) shall be used to indicate the machine direction of the sample. 3.1.3.3 The sample shall be marked for identification purposes with the following information: brand/producer/supplier; type description, e.g. quality number or grade; roll number or other identification if more than one roll
31、 of the same type is sampled; date of sampling. 3.1.3.4 If the sample is not to be cut into specimens immediately, it shall be kept in a dry, dark place, free from dust, at ambient temperature and protected against chemical and physical damage. NOTEThe sample may be rolled up but preferably not fold
32、ed. Quantity of product typeMinimum number of samples to be taken Less than 5 000 m2 1 From 5 000 to 20 000 m21 every 5 000 m2 More than 20 000 m24 + 1 every 10 000 m2 Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 07 05:39:47 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 963:1995 4 BSI 08-1999
33、 3.2 Preparation of specimens 3.2.1 For each type of test, the required number of specimens shall be cut from positions evenly distributed over the full width and length of the sample, but not closer than 100 mm to the edge. 3.2.2 Except for specimens for tests, to be made in connection with claims
34、(see 3.1.1.2), specimens shall not contain any dirt, irregular areas, creases, holes or other visible defects of accidental origin produced subsequent to manufacture. 3.2.3 For the same type of test the same longitudinal or transverse position of two or more specimens shall be avoided. If unavoidabl
35、e (e.g. due to narrow roll width) a note to this effect shall be included in the sampling report. 3.2.4 Except when additional tests are required, the specimens shall be cut along the machine and transverse directions. When the test procedure calls for the specimen to be marked with the machine dire
36、ction, the marking indicating the machine direction on the sample shall be transferred to the specimen, or the specimen shall be kept separate in such a way that there can be no risk of a misunderstanding. 3.2.5 The specimens shall be cut to the precision required for the particular test. NOTEIn tes
37、ts where accuracy of dimensions is of special importance, the specimens may be cut to an oversize and then cut or frayed to exact dimensions after conditioning. 3.2.6 The identification markings on the sample shall be carefully transferred to all test specimens for each test. 3.2.7 When cutting test
38、 specimens reference shall be made to the particular test standards for which the specimens are being prepared. 3.2.8 If the cutting causes fragments of the geotextile or geotextile-related products to become loose, or if accidental fraying occurs, all loose fragments shall be kept with the specimen
39、 until the test is carried out. If the loosening of fragments cannot be avoided and this is likely to influence the test result, the fact that loosening has occurred shall be reported in the sampling report as well as in the test report. 3.2.9 The specimens shall be kept in a dry, dark place free fr
40、om dust, at ambient temperature and protected against chemical and physical damage until the test is performed. 4 Sampling report The sampling report shall include the following particulars: a) a statement that the sampling and preparation of specimens was performed in accordance with this European
41、Standard; b) details of any special observations made during the selection, sampling or preparation of specimens, such as; an unusually high number of defects; loosening of fragments from the geotextile or geotextile-related product; the necessity for taking specimens for same test in only one longi
42、tudinal or transverse direction; c) details of any deviation from the specified sampling procedure; d) date of sampling, and reference number(s) of the rolls selected.
