21、ollowing sampling procedure shall be applied to determine whether a lot submitted for inspection and testing complies with the requirements of the standard. The samples so taken shall be deemed to represent the lot for the respective properties. The sampling procedure shall also be used for adjudica
22、tion in cases of dispute. 5.1.2 Sample for inspection Draw at random from the lot a) five containers if the lot is packed in containers of net mass not exceeding 5 kg, and b) three containers if the lot is packed in containers of net mass greater than 5 kg. SANS 240:2008 Edition 3 6 5.1.3 Sample for
23、 testing 5.1.3.1 From the containers taken in accordance with 5.1.2, take at random enough soap to provide a laboratory sample of total mass at least 2 kg (take equal quantities of soap from all containers). 5.1.3.2 Place the laboratory sample in clean, dry, air-tight glass or plastics containers cl
24、early marked with the manufacturers name or trade mark, the batch identification, and the date of sampling. 5.1.3.3 In the case of unwrapped soap, take the sample bars or tablets (as relevant) from the centre of the container. 5.2 Compliance with the standard Deem the lot to comply with the requirem
25、ents of the standard if, after inspection and testing of the samples taken in accordance with 5.1.2 and 5.1.3, the samples are found to comply with all the requirements of the standard. 6 Inspection and methods of test 6.1 Inspection 6.1.1 Inspect the containers (and when relevant the wrappers) take
26、n in accordance with 5.1.2, for compliance with the requirements of clause 7. 6.1.2 Visually examine the samples taken in accordance with 5.1.2 for compliance with the requirements given in 4.1.1 and 4.2. 6.2 Preparation of test specimens 6.2.1 Composite specimen 6.2.1.1 Determine and record the mas
27、s of each unit taken in accordance with 5.1.3 (including any material that may have adhered to the wrapper or to the sample container, as relevant). Calculate the average mass. 6.2.1.2 Divide each unit into eight equal parts by cutting it through three times (through the middle of the unit). Ensure
28、that all the three cuts are at right angles to one another. 6.2.1.3 Completely slice or grate finely two diagonally opposite eighths of each unit. 6.2.1.4 Combine all the slices or gratings in a clean, dry, air-tight glass or plastics container (identified as in 5.1.3), and mix thoroughly. 6.2.2 Tes
29、t specimens 6.2.2.1 Immediately after preparing the composite specimen, take at one time all the test specimens required for analysis. 6.2.2.2 Weigh out the test specimen required for the determination of free alkali or free acid content last, and test it immediately. SANS 240:2008 Edition 3 7 6.2.2

Check for compliance with table 1. 7 Packing and marking 7.1 Packing 7.1.1 Unless otherwise required (see annex A), the carbolic
33、 soap shall, when visually examined, be so wrapped as to prevent excessive drying out, contamination of the product, and staining of the wrapper. The flaps of the wrapper shall be properly secured. 7.1.2 The carbolic soap shall be packed in containers that are strong enough to withstand normal usage
34、 and transportation. These containers may then be packed in bulk packages. Only soap from the same batch shall be packed together in a container and, when relevant, in a bulk package. SANS 240:2008 Edition 3 8 7.2 Marking Each container, bulk package and when relevant each wrapper shall bear in prom

36、entification (this may appear on containers only); d the mass, in grams, of the contents; e) in the case of containers, the number of bars or tablets; and f) in the case of bulk packages, the number of containers, or of bars or tablets. SANS 240:2008 Edition 3 9 Annex A (normative) Notes to purchasers The following requirements shall be specified in tender invitations and in each order or contract: a) the colour of the soap (see 4.1.1(c); and b) when relevant, that the soap shall not be wrapped (see 7.1.1).
