11、3 Wax emulsion polish for floors and furniture 1 Scope 1.1 This specification covers wax emulsion paste polish and two types of wax emulsion liquid polish suitable for use on furniture and floors other than (in the case of polish containing an organic solvent) those of thermoplastic (asphalt), semi-
12、flexible vinyl (vinyl-asbestos), flexible vinyl, linoleum, and rubber. NOTE a) The titles of standards referred to by number in the specification are given in appendix A. b) Requirements that must be specified by the purchaser are listed in appendix B. 2 Definitions 2.1 For the purposes of this spec
13、ification 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 2 batch the material from a single mix defective wax polish or its container or bulk package that fails in
14、one or more respects to comply with the appropriate requirements of the specification lot that quantity of wax polish in containers that bear the same batch identification, from one manufacturer, submitted at any one time for inspection and testing 3 Requirements 3.1 General The polish shall consist
15、 essentially of a wax or a blend of waxes in water or, when relevant, a mixture of water and organic solvents. It shall not be harmful to, or discolour surfaces of the types to which it is intended to be applied. It shall not be irritating to the normal skin and its vapours shall not be toxic to hum
16、an beings under normal conditions of use. The odour of the polish shall be acceptable. SANS 15:2008 Edition 2.3 4 3.2 Form and type 3.2.1 Form The wax polish shall be either a liquid or a paste, as specified by the purchaser, and shall comply with the following requirements: a) Liquid polish. Liquid
17、 polish shall be a free-flowing homogeneous liquid between 15 and 30 C and free from lumps or solid particles. b) Paste polish. Paste polish shall be a homogeneous smooth paste free from lumps and granulations. 3.2.2 Type Liquid polish shall be of one of the following types, as specified by the purc
18、haser: Type 1. Polish containing organic solvents. Type 2. Polish containing no organic solvent. 3.3 Freedom from grit When approximately 0,1 g of the polish is rubbed between two glass slides, there shall be no evidence of grittiness. 3.4 Colour The colour of the paste polish shall be as specified
19、by the purchaser. 3.5 Heat-cool stability When tested in accordance with 6.3, paste polish shall not show signs of separation, and there shall be not more than 5 mL separation of suspended matter from 100 mL of liquid polish. 3.6 Penetration The penetration of paste polish, determined in accordance
20、with 6.4, shall be 50 95 units (tenths of a millimetre) at 20 C and not more than 90 units (tenths of a millimetre) at 35 C. Amdt 1; amdt 2 3.7 Performance When tested in accordance with 6.5, the polish shall apply easily and shall dry to a thin non-tacky film within 15 min. On rubbing with a soft c
21、loth, the film shall polish smoothly and the gloss of the panel shall not be reduced. 3.8 Non-volatile matter 3.8.1 Content The non-volatile matter content of the polish, determined in accordance with 6.6, shall be as follows: SANS 15:2008 Edition 2.3 5 a) Liquid polish. Not less than 10,0 % (m/m).
22、b) Paste polish. Not less than 18,0 % (m/m). Amdt 1 3.8.2 Properties The non-volatile matter of the polish shall comply with the requirements given in table 1. Table 1 Properties of the non-volatile matter 1 2 3 4 Requirement Property Liquid Paste Test method subsection Softening point, C, min. 70 7
23、0 6.7 Ash content, % (m/m), max. 1,0 1,0 6.8 Amdt 1 3.9 Organic solvent If present, the solvent shall have a flash point, determined in accordance with 6.9, of at least 25 C. 3.10 Storage stability When stored at room temperature for 12 months in its original unopened container, the polish shall com
24、ply 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 be packed in metal containers. It shall be so packed as to prevent leakage and deterioration of the product,
25、 and the containers shall be strong enough to withstand normal handling and transportation. Each container shall contain only polish from the same batch. The containers may be packed in bulk packages, but only containers of the same size and bearing the same batch identification shall be packed toge
26、ther in a bulk package. 4.2 Marking 4.2.1 Container Each container shall bear in prominent, legible, and indelible marking the information required in terms of the relevant national regulations and statutory requirements regarding trade metrology (see foreword), and the following additional informat
27、ion: Amdt 3 a) The name or trade name or trade mark of the manufacturer, or a combination of these; b) the words “Wax emulsion polish“; c) in the case of liquid polish, the type; 1) It is not recommended that polish containing an organic solvent be packed in a container of polyethylene. SANS 15:2008
28、 Edition 2.3 6 d) the colour; e) the net volume of the contents; f) if larger than 1 L, the batch identification. 4.2.2 Bulk packages Each bulk package shall bear, in legible and indelible marking, the following information: a) The information required in terms of 4.2.1(a), (b), (c), and (d); b) the
29、 capacity and number of containers; c) the form of the polish; d) the batch identification. 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
30、 about the implementation of quality control or testing during manufacture is available to help in assessing the quality of the lot. It is also used as the procedure for adjudicating in cases of dispute. 5.1 Sampling The following sampling procedure shall be applied in determining whether a lot comp
31、lies with the appropriate requirements of the specification. The sample so drawn shall be deemed to represent the lot. After inspecting the lot for compliance with the appropriate requirements of section 4, take from it at random at least six containers and mark each container with the date of sampl
32、ing and, when 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
33、methods of test 6.1 Inspection Inspect the containers in the sample taken in accordance with 5.1 for compliance with the appropriate requirements of section 4, and after conditioning (see 6.2), check their contents for compliance with those requirements of the specification compliance with which is
34、not assessed by the tests given in 6.3 6.9 (inclusive). 6.2 Conditioning of samples Condition all samples at room temperature for at least 7 d before testing.
