Page 2, Subclause 2.5 Insert the following paragraph after the first paragraph of Subclause 2.5. "The colour appearance of samples can be affected by the colour of the surround against which they are viewed and the colour of any material that is used to mask them. In order to obtain reliable test results using IsO 105-A02, the samples shall be masked with a material that is identical in colour to the sleeve that is used to mask the test strip being used. Chromatically neutral surrounds and sleeves should be used but, with proper use, grey or black sleeves are acceptable. Proper use entails that, for example, if the test strip is used with a black sleeve then the samples shall be masked using an identical black material or, if a single mask which shall be neutral in color is used, then it shall completely surround both the test strip and the samples."
