The cleaning agent shall be stored in a glass bottle in a coo

33、l dark place and should be used within 1 year of the day of preparation. 5.11 Hand spray pump for applying the cleaning solution. 5.12 Staining agents the set of staining agents to be used for the test is defined in Annex A. 6 Preparation of specimens 6.1 Sampling The method of sampling shall be sta

34、ted in the test report and shall be chosen so that the samples are representative of the batch to be tested. DIN EN 16301:2013-05 EN 16301:2013 (E) 7 6.2 Test specimens 6.2.1 Surface finish For identification test and comparison, the specimens shall have a “matt finished surface”. NOTE Schist and sl

35、ate are exceptions to this rule. They can be tested on natural cleft surface. For “technological testing”, surfaces with a roughness 0,5 mm are not suitable for testing due to the risk of damaging the apparatus. 6.2.2 Dimensions One sample set consists of three test specimens sized, minimum 300 mm b

36、y 100 mm, and thickness as in use (maximum 30 mm). Alternative dimensions can be used if different cleaning equipment is used. 6.2.3 Testing environment The test specimens shall be placed in (23 5) C and (50 5) % relative humidity during the entire stain exposure. Daylight or artificial light D65 is

37、 used during the photography and the evaluation. 6.2.4 Pre-conditioning and treatment of the specimens Marble and limestone shall be dried in (40 5) C for one week before the test. Other stone types shall be dried in (70 5) C for at least 24 h. Commercially used stone products are sometimes impregna

38、ted in some way to make them easier to clean. The traditional treatment of carbonaceous stones is soft soap, which partially seals the pores and makes the surface a bit more hydrophobic. For standard test the stones shall be non-treated as a reference. If a carbonaceous stone type is tested, one set

39、 should also be treated with soft soap 2,5 vol. % solution in water, or similar which is recommended by the Stone Industry federations. The soap treatment is not mandatory, but highly recommended. Instruction for the treatment with soft soap: the solution is sprayed on with a hand-pumped spray; afte

40、r 3 h: The next layer is applied; after another 21 h: The excess shall be rinsed off under running water. The test specimens are kept in (23 5) C and (50 5) % relative humidity for a minimum 16 h before applying the staining agents. If a surface treatment/coating chemical or impregnation chemical sh

41、all be tested, the procedure of applying this shall be documented and follow the manufacturers instruction. 7 Procedure 7.1 Documentation of the test specimens Document the test specimens by digital photography before the stains are applied. Use daylight or artificial light D65. The photographs shou

42、ld be scaled. DIN EN 16301:2013-05 EN 16301:2013 (E) 8 7.2 Staining agents to be used in the standard test The set of staining agents to be used for the test is defined in Annex A. NOTE For specific uses, it may be required to use also urine and blueberry soup (Annex A). Other products can be used a

43、nd prepared according to instructions by the manufacturer or commissioner. 7.3 Staining procedure All samples have to be stained in the same way. The stains shall have the same size and shape. All staining shall be performed at (23 5) C and (50 5) % relative humidity. The samples shall remain in thi

44、s atmosphere during the whole exposure time, usually 15 min and (48 1) hours as a default value. Other time schedules may be used provided that the commissioner asks for it. The diameter of the stains shall be (35 5) mm. NOTE Most water based stains, like Cola, wine and coffee has the same surface p

45、roperties and a suitable stain volume is 0,70 ml. This volume is also sufficient for ketchup which shall be spread out to the same size. A stain like oil has completely different surface properties and immediately floats out on most stone materials. To get a stain in the same size as for the water b

46、ased products a volume of 0,15 ml is suitable. Surface treated samples may need the staining agent to be spread out to reach the optimal 35 mm . Dimensions in millimetres Figure 3 Optimal sample size and stain pattern 7.4 Cleaning procedure Gently remove possible liquid residues of the stains with a

47、bsorb and dry paper. Apply the correct load to the cleaning arm, (350 10) g (arm, cloth and cloth holder). Prepare cleaning solution with 15 ml of the cleaning agent (ref. 5.10) in 1000 ml deionized or distilled water. Spray cleaning solution on the stains 4 min before the cleaning. Soak the cleanin

48、g cloth in cleaning solution. DIN EN 16301:2013-05 EN 16301:2013 (E) 9 Mount the cleaning cloth and the holder to the scrubbing arm. The stained surfaces are then washed with a “Wet Abrasion Scrub Tester”. Ten cleaning cycles (10 strokes back and forth) shall be used in all tests. Rinse the surfaces

49、 with 150 ml water to remove residues of the cleaning solution. Condition the test specimens for 24 h in (23 5) C and (50 5) % relative humidity before they are photographed and evaluated. Photograph the test specimens in using the same scaling and light conditions used to photograph the test specimen before staining. 8 Evaluation of staining and expression of the result A visual observation of the residual staining shall be made according to the followin
