Remove the test specimens from the water and dab with wet but wrung out chamois leather. Secondarily examine the parts of the cut edges that were immersed. Use in a concentration of 1 g dry substance per litre. NOTE — The soap can be prepared from concentrated sodium hydroxide solution and oleic acid in the proportion of 2.

The bottom edge of the cylinder shall be ground flat and perpendicular to the vertical axis of the cylinder. Variations from the experimental 18 IS Part 8: Place an approximately 30 mm diameter convex watch glass on the applied drop in order to spread it to an approximately circular area.

Allow to remain for 24 h and then rinse the surface with running water and wipe with a damp cloth. If a stain remains, thoroughly clean with a solution of the standard cleaning agent. Turn the cylinder upside down onto a fresh part of the glazed surface as shown in Fig. Remove the cylinder and clean the glazed surface with a grease solvent. Replace the test solution after 4 days.

After 3 more days, remove the cylinder and clean the glazed surface with a grease solvent. In order to assess whether the pencil test is applicable, draw several lines with an HB pencil on the untreated parts of the glazed surfaces and attempt to remove the marks with a dry cloth. If the pencil marks cannot be removed, the test specimens can only be assessed visually and the classification scheme of Fig. For all other test specimens, the assessment shall be carried out according to 7.

If there is a visible effect, perform the reflection test see 7. If removed, the surface corresponds to Class AA. If not removed, attempt to remove the pencil lines by means of a soft damp cloth which has been dampened by dipping in distilled or de-ionized water and then wringing out.

If removed surface corresponds to Class A, if not removed to Class B. Position the tile so that the image fall simultaneously on both treated and untreated part and determine whether it is any less clear in the treated part.

If the lines are removed the surface corresponds to Class A; if not removed to Class B. Record the result for each test specimen with each stain solution. Record the result for each test specimen with each test solution 8.
