14、tablet form; b) be homogeneous and of firm consistency; and c) when coloured, be uniform in shade. 4.1.2 Filled bar soap shall not be irritating to normal skin and it shall not contain ingredients in quantities that are toxic to human beings. It shall possess good lathering properties in water, at a
15、mbient temperature, that has a hardness (expressed as calcium carbonate) of 200 10-6. 4.2 Odour Filled bar soap, both as received and when dissolved in hot water, shall posses a pleasant odour and shall not develop an objectionable one during storage at ambient temperature. 4.3 Chemical requirements

20、e 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 adjudication in cases of dispute. 5.1.2 Sam
21、ple 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 exceeding 5 kg. SANS 236:2008 Edition 3 6 5.1.3 Sample for testing 5.1.3.1 From the containers t
22、aken in accordance with 5.1.2, take at random enough soap to provide a sample of total mass at least 2 kg (take equal quantities of soap from all containers). 5.1.3.2 Place the sample in clean, dry, air-tight glass or plastics containers clearly marked with the manufacturers name or trademark, the b
23、atch identification, and the date of sampling. 5.2 Compliance with the specification Deem the lot to comply with the requirements 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
24、 standard. 6 Inspection and methods of test 6.1 Inspection 6.1.1 Inspect the containers (and when relevant the wrappers) taken in accordance with 5.1.3 for compliance with the requirements of clause 7. 6.1.2 Visually examine the samples taken in accordance with 5.1.3 for compliance with the requirem
25、ents given in 4.1 and 4.2. 6.2 Preparation of test specimens 6.2.1 Composite specimen 6.2.1.1 Determine and record the mass 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
26、.2.1.2 Divide each unit into eight equal parts by cutting the unit through three times (through the middle of the unit), the three cuts all being at right angles to each other. 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 gr
27、atings in a clean, dry, air-tight glass or plastics container (identified as in 5.1.3.2), and mix thoroughly. 6.2.2 Test specimen 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 fo
28、r the determination 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.
