11、ionally left blank SANS 258:2008 Edition 2.4 3 Wax stoep polish 1 Scope 1.1 This specification covers wax polish suitable for use on surfaces of cement, and available in three colours. NOTE a) The standards referred to in the specification are listed in appendix A. b) Requirements that must be speci
12、fied by the purchaser are listed in appendix B. 2 Definitions 2.1 For the purposes of this specification the following definitions shall apply: acceptable acceptable to the authority administering this standard or to the parties concluding the purchase contract, as relevant Amdt 1; amdt 3 batch the
13、material from a single mix defective stoep polish or its container that fails in one or more respects to comply with the appropriate requirements of the specification lot not less than 10 containers of stoep polish that bear the same batch identification, from one manufacturer, submitted at any one
14、time for inspection and testing 3 Requirements 3.1 General The polish shall consist essentially of a wax or a blend of waxes and pigments in a mixture of water and organic solvents. It shall be a homogeneous smooth paste free from lumps and granules. It shall not be harmful to surfaces of the cement
15、 type. Under normal conditions of use it shall not be irritating to the normal skin and its vapours shall not be toxic to human beings. The odour of the polish shall be acceptable. SANS 258:2008 Edition 2.4 4 3.2 Freedom from grit When approximately 0,1 g of the polish is rubbed between two glass sl
16、ides, there shall be no evidence of grit. 3.3 Colour The colour of the polish shall be an acceptable shade of black, green, or red, as specified by the purchaser. 3.4 Heat-cool stability When tested in accordance with 6.3, the polish shall not show any sign of separation. 3.5 Penetration The penetra
17、tion of the polish, determined in accordance with 6.4, shall be in the range 60-110 units (tenths of a millimetre) at 20 C and not more than 90 units (tenths of a millimetre) at 25 C. Amdt 1 3.6 Performance When tested in accordance with 6.5, the polish shall apply easily and shall dry to a thin fil
18、m within 15 min. On rubbing with a soft cloth, the film shall polish smoothly and the gloss of the panel shall not be reduced. Amdt 1 3.7 Non-volatile matter 3.7.1 Content The non-volatile matter content of the polish, determined in accordance with 6.6, shall be not less than 22 % (m/m) in the cases
19、 of red and green polishes and not less than 20 % (m/m) in the case of a black polish. Amdt 1 3.7.2 Properties The non-volatile matter of the polish shall comply with the requirements given in table 1.

21、 When stored at room temperature for 12 months in its original unopened container, the polish shall still comply with all the other relevant requirements of the specification. 4 Packing and marking 4.1 Packing Unless containers of a plastics material1)are specified by the purchaser, the polish shall
22、 be packed in metal containers. It shall be so packed as to prevent leakage and deterioration of the product and the containers shall be strong enough to withstand normal handling and transportation. Each container shall contain only polish from the same batch. These containers may be packed in bulk
23、 packages, but only containers of the same size and bearing the same batch identification shall be packed together in a bulk package. 4.2 Marking Each container shall bear, in prominent, legible and indelible marking, the information required in terms of the relevant national and statutory requireme
24、nts regarding trade metrology (see foreword), and the following additional information (which shall also appear on each bulk package): Amdt 4 a) The name or trade name or trade mark of the manufacturer, or a combination of these; b) in the case of containers, 1) words indicating that the polish is a
25、 wax polish intended for use on cement surfaces; 2) the colour; 3) the net volume of the contents; 4) if larger than 1 L, the batch identification; c) in the case of bulk packages, 1) a description of the contents (that includes the colour); 2) the batch identification; 3) the number of containers.
26、5 Sampling and compliance with the specification NOTE This section applies to the sampling for inspection and testing before acceptance or rejection of single lots (consignments) in cases where no information about the implementation of quality control or testing during manufacture is available to h
27、elp in assessing the quality of the lot. It is also used as the procedure for adjudicating in cases of dispute. 1) It is not recommended that the container be of polyethylene. SANS 258:2008 Edition 2.4 6 5.1 Sampling The following sampling procedure shall be applied in determining whether a lot comp
28、lies with the appropriate requirements of the specification. The sample so drawn shall be deemed to represent the lot. After checking the lot for compliance with the requirements of section 4, take from it at random at least six containers and mark each container with the date of sampling and, when
29、relevant, the batch number. 5.2 Compliance with the specification The lot shall be deemed to comply with the requirements of the specification if, after inspection of the lot and inspection and testing of the sample taken in accordance with 5.1, no defective is found. 6 Inspection and methods of tes
30、t 6.1 Inspection After conditioning (see 6.2) the containers in the sample taken in accordance with 5.1, check their contents for compliance with those requirements of the specification with which compliance is not assessed by the tests given in 6.36.9 (inclusive). 6.2 Conditioning of samples Condit
31、ion all samples at room temperature for at least 7 d before testing. 6.3 Heat-cool stability Use SANS 5976. 6.4 Penetration Use SANS 5977 but modified as follows: a) Condition one of the two test samples at 20,0 0,5 C for 24 h and the other sample at 25,0 0,5 C for 24 h. b) Determine the penetration
32、 of the polish conditioned at 20,0 0,5 C, using the 60/90 cone, and determine the penetration of the sample conditioned at 25,0 0,5 C, using the 90 cone. c) Report the penetration of the polish at 20 C and at 25 C. Amdt 1 6.5 Performance Use the procedure given in section 3 of SANS 5978:2008, but om
33、it the step given in 3.3. Amdt 1 6.6 Non-volatile matter content Use SANS 5981. Amdt 4 6.7 Softening point of the non-volatile matter Use SANS 5980. SANS 258:2008 Edition 2.4 7 6.8 Ash content of the non-volatile matter Use SANS 5981. 6.9 Flash point of solvents Use ASTM D93. SANS 258:2008 Edition 2
