25、which a judgement is desired (usually as to compliance with specification) and which are available for sampling. NOTES 1 The number of sacks comprising a lot may be indicated on the in- voice or agreed upon by the contracting parties. 2 When the number of sacks available for sampling is less than th
26、e 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 to clause 1. 3.2 unit : The unit may be in the form of a bundle, bale, pallet load, container load, etc. One or more nominally identical units constitute
27、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 accor- ding to a prescribed procedure to represent the lot. 3.5 selected
28、 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 of units from the lot (see 5.1). b) Use of
29、 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 (see 5.2.1). 2) Where the unit is subdivided into elements, selec- tion of a prescribed number of elements from each of these units, then selec
30、tion of a prescribed number of sacks from these elements (see 5.2.2). 5 Procedure 5.1 Selection of units Determine and select the number of units to be sampled, accor- ding to table 1. NOTE - Table 1 has been taken from IS0 186. Table 1 I Number of units In) Number of units I in the lot 1 selected l
31、ess than 20 units shall be ignored. The units selected shall be intact and in good external condi- tion.

For each unit selected from the lot, proceed as follows : 5.2.1 When the unit
33、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 sacks required for testing and conforms to the re- quirements of table 2. NOTE - Relevant information for table 2 has been extracted from
34、the first two columns in both tables I-A and Il-A of IS0 3951. 5.2.2 When the unit is subdivided into elements If there are 20 or more elements in each unit, assemble all the elements in the selected units and, using table 1, select the elements in the same way that the units were selected. If there
35、 are less than 20 elements in each unit, select one ele- ment at random from each unit. At least one element should be selected from each unit. Finally, take at random an equal number of sacks from each ele- ment selected so that the total number taken from the lot is not less than the number of sac
36、ks required for testing and con- forms to the requirements of table 2. 6 Additional requirements 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, follow- ing the above procedure. Selection may then, however, be ma
37、de from the same units as before unless agreed otherwise. 6.3.2 If re-sampling is needed for any other reason, the pro- cedure adopted should follow this specification as closely as possible . 7 Test report The report shall indicate the following particulars : a) a reference to this International St
38、andard: 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 number of elements selected; j) the number of sac
39、ks in the lot: k) the number of sacks selected: m) any circumstances which might influence the results of future tests; n) a reference corresponding to the identification marks on the sacks; 6.1 Precautions p) the signature of the person carrying out the sampling; The sacks selected shall be kept and handled so that there is no permanent change in their properties before testing. q) any deviation from this International Standard.
