22、the implementation of quality control or testing during manufacture is available, the following 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 lo
23、t for the respective properties. The sampling procedure shall also be used for adjudication 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 volume not exceeding 5 L, and b) three containers if the lot is packed
24、 in containers of net volume greater than 5 L. 5.1.3 Sample for 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 volume at least 1 L (take equal quantities of soap from all containers). 5.1.3.2 Before drawing a sam
25、ple, thoroughly mix the contents of the container. SANS 238:2008 Edition 3 6 5.1.3.3 Pour the laboratory sample in clean, dry, air-tight glass or plastics containers clearly marked with the manufacturers name or trade mark, the batch identification, and the date of sampling. 5.2 Compliance with the

28、le taken in accordance with 5.1.3 by vigorously shaking it in the original glass or plastics bottle. 6.2.2 Test 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 de
29、termination of free alkali or free acid content last, and test it immediately. 6.2.2.3 Ensure that any pick-up or loss of moisture is reduced to a minimum by carrying out the weighing and the preparation of the test specimens as rapidly as possible. 6.3 Free alkali content or free acid content Use S

These containers
33、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. 7.2 Marking Each container and bulk package shall bear in prominent, legible and indelible marking the information required in terms of the relevant natio
34、nal regulations and statutory requirements (see foreword) and the following additional information, as relevant: a) the manufacturers name or trade mark or both; b) the words “Liquid Toilet Soap“; c) the batch identification (this may appear on containers only); d) the volume, in litres, of the cont
35、ents; and e) in the case of bulk packages, the number of containers. SANS 238:2008 Edition 3 8 Annex A (normative) Notes to purchasers The following requirement shall be specified in tender invitations and in each order or contract: when relevant, that the soap shall not be perfumed (see 4.2).
