These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard, only when incorporated in it by amendment or revision.

The light source shall have a correlated colour temperature of (6500 ± 50) K and an Ra greater than 92, by using a colour matching booth in accordance with EN ISO 3668. 6.1.2.2Direct light source, 60 W frosted bulb so screened that light reaches the test area only from the bulb and that the bulb is not in direct view of the tester. The angle between the horizontal and a line between the bulb and the area under examination shall be 30° to 60° . NOTEThese conditions are fulfilled when the direct source is placed in a viewing cabinet as shown in Figure 2. 6.2 Test equipment 6.2.1 Pieces of cellulose filter paper to apply each of the test agents, free of dyes and of chemicals, with a grammage of 400 g/m2 to 500 g/m2. They shall have an area of (500 ± 50) mm2. Their shape shall be chosen to suit the surface of a small element or a small single parquet strip without overlapping the edges of the element or parquet strip to be tested.

The house keeping detergent shall be stored in a glass bottle in a cool dark place and should be used within 1 year of the day of preparation. 6.3.2.3Cleansing solution containing 15 ml/l of the house keeping detergent (see 6.3.2.2) in water (see 6.3.2.1). This solution shall be freshly prepared on each occasion. 7 Procedure 7.1 Test pieces and test specimen If the test piece or test specimen is coated, carry out the test after full curing of the coating. Relevant information shall be provided by the manufacturer. Wipe the test surface carefully with a dry cloth (see 6.2.5) before testing. 7.2 Chemical test Immediately after the conditioning, if any, carry out the test in an atmosphere of (20 ± 5) °C. Place the test surface horizontally. Test it with the test agents specified in 6.3.1 at test areas, their centre being not more and not less than 60 mm apart, centre to centre and not less than 40 mm from any edge of the test surface. Immerse a piece of filter paper (see 6.2.1) into a test agent (see 6.3.1) for 30 s, lift with the pair of tweezers (see 6.2.3) and wipe off against the edge of the vessel (see 6.2.6). Quickly place the filter paper on the test area and immediately cover with an inverted glass Petri dish (see 6.2.2). The filter paper shall not touch the edge of the glass Petri dish. Record the position of each impregnated paper on each test area for each test agent. After the stated duration for each test agent used (see 6.3.1), remove the glass Petri dish and lift off the filter paper with the pair of tweezers. Do not remove fibres of paper adhering to the test area. Soak up any remaining test agent with the absorbent paper (see 6.2.4) without rubbing and leave the test surface undisturbed for 16 h to 24 h in the test atmosphere without covering it. The test area shall be sufficiently protected against dust without limiting in any way the free access of air. After the expiry of the 16 h to 24 h, wash the test surface by lightly rubbing it with th
