20、3:1992 BSI 10-1999 3 1 Scope and field of application This International Standard specifies a method of obtaining a representative sample of empty sacks for testing. This International Standard is applicable when sampling in order to assess the average quality of a consignment of empty sacks. The me
21、thod is not suited to sampling for production control. The method applies to all types of empty sacks. NOTEIt should be noted that the sample is representative only of those sacks available for sampling. Considerable caution should be exercised when extrapolating the results from such sampling to a
22、larger consignment. 2 References ISO 186, Paper and board Sampling for testing. ISO 3951, Sampling procedures and charts for inspection by variables for percent defective. 3 Definitions For the purpose of this International Standard, the following definitions apply. 3.1 lot the aggregate of sacks wh
23、ich are of a single kind with specified characteristics, on which a judgement is desired (usually as to compliance with specification) and which are available for sampling NOTE 1The number of sacks comprising a lot may be indicated on the invoice or agreed upon by the contracting parties. NOTE 2When
24、 the number of sacks available for sampling is less than the lot size agreed or indicated on the invoice, the total number of sacks available may be taken as a lot subject to the caution given in the note toclause1. 3.2 unit the unit may be in the form of a bundle, bale, pallet load, container load,
25、 etc. One or more nominally identical units constitute a lot 3.3 element the element may be in the form of a bundle, bale, pallet load etc., but cannot be a single sack. One or more nominally identical elements constitute a unit 3.4 sample a specified number of sacks selected according to a prescrib
26、ed procedure to represent the lot 3.5 selected at random taken in such a way that each part of the whole has an equal chance of being selected 4 Principle Selection at random of a prescribed number of sacks from the lot following a two-stage procedure as follows: a) Selection of a prescribed number
27、of units from the lot (see5.1). b) Use of one of the following two procedures: 1) Where the unit is not subdivided into elements, selection of a prescribed number of sacks from each of these units (see5.2.1). 2) Where the unit is subdivided into elements, selection of a prescribed number of elements
28、 from each of these units, then selection of a prescribed number of sacks from these elements (see5.2.2). 5 Procedure 5.1 Selection of units Determine and select the number of units to be sampled, according to Table 1. NOTETable 1 has been taken from ISO186. Table 1 The units selected shall be intac
29、t and in good external condition. 5.2 Selection of sacks For each unit selected from the lot, proceed as follows: 5.2.1 When the unit is not subdivided into elements Take at random an equal number of sacks from each unit so that the total number taken from the lot is not less than the number of sack
30、s required for testing and conforms to the requirements ofTable 2. NOTERelevant information forTable 2 has been extracted from the first two columns in both TablesI-A and II-A of ISO3951. Number of units (n) in the lot Number of units selected Method of selection 1 to5 all 6 to99 5 at random 100 to
31、399 a at random 400 or more 20 at random a In deciding the number of units to be selected, any remainder of less than 20 units shall be ignored. n 20 -EN27023:1992 4 BSI 10-1999 Table 2 5.2.2 When the unit is subdivided into elements If there are20or more elements in each unit, assemble all the elem
32、ents in the selected units and, usingTable 1, select the elements in the same way that the units were selected. If there are less than20elements in each unit, select one element at random from each unit. At least one element should be selected from each unit. Finally, take at random an equal number
33、of sacks from each element selected so that the total number taken from the lot is not less than the number of sacks required for testing and conforms to the requirements of Table 2. 6 Additional requirements 6.1 Precautions The sacks selected shall be kept and handled so that there is no permanent
34、change in their properties before testing. 6.2 Marking Each sack that has been selected shall have adequate identification marks to prove its origin. 6.3 Re-sampling 6.3.1 If, as a result of an accident during sampling or testing, re-sampling is necessary, a new sample shall be taken, following the
35、above procedure. Selection may then, however, be made from the same units as before unless agreed otherwise. 6.3.2 If re-sampling is needed for any other reason, the procedure adopted should follow this specification as closely as possible. 7 Test report The report shall indicate the following parti
36、culars: a) a reference to this International Standard; b) the names and addresses of the purchaser and vendor; c) the date and place of sampling; d) the description of the lot; e) the number of units in the lot; f) the number of units selected; g) the number of elements, if any, in a unit; h) the nu
