25、lectroformed sheet Nominal sizes of openings ISO 1957, Machine-made textile floor coverings Selection and cutting of specimens for physical tests 3 Principle In both tests a fixed quantity of standard artificial soil is scattered over the surface of the specimens which is also subjected to the rolli
26、ng action of castors or of tetrapod feet for a specified time. After vacuum cleaning, the degree of colour change is assessed by comparing the contrast between treated and untreated test specimens with the contrast of the grey scale. Depending on the type of apparatus available, either method A or m
27、ethod B can be used. 4 Apparatus 4.1 Method A 4.1.1 Castor chair apparatus, As described in EN 985, with a total load of 60 daN. 4.1.2 Soil distributor The soil distributor uses two sieves, one inside and resting on the other to distribute the soil evenly on the part of the circular specimen that is
28、 subjected to the wear action of the castors. The whole distributor is placed vertically above the specimen with the sieves in the horizontal position. The soil is placed in the inner sieve which is vibrated relative to the larger outer sieve thereby achieving even distribution of the soil on the sp
29、ecimen below the two sieves. The mesh size of both sieves is 0,5 mm (module 31 of ISO 565). The base of each sieve (each of which has walls) is in the shape of a regular trapezium in order to correspond to a sector of the treated area of the test specimen. The outer (lower) sieve has following base
30、dimensions: DIN EN 10303:2016-02 EN 1269:2015 (E) 5 distance between the parallel sides: 220 mm; length of the parallel sides: 100 mm, 45 mm. Its underside is 40 mm above the specimen. The dimensions of the inner (upper) sieve are not specified but shall be smaller than the base sieve to permit move
31、ment relative to the lower sieve. 4.2 Method B 4.2.1 Drum A rigid cylindrical drum with bottom and lid shall be used. The inner diameter is (205 5) mm and the inner height of the drum is (200 10) mm. The drum is made of polyvinylchloride (PVC), with a thickness of at least 6 mm. The bottom and lid a
32、re attached to the wall by appropriate means. The lid of the drum is preferably made of transparent material, e.g. Polymethylmethacrylate (PMMA.). 4.2.2 Tetrapod A tumbler consisting of a central metal sphere with four outer feet arranged in the shape of a regular tetrahedron. Each foot is covered w
33、ith a spherical polyurethane cap. In operation the tetrapod tumbles inside the rotating drum so that the feet impact on the test specimen lining the drum. Tetrapod specifications: total mass: (1 000 25) g; angle between any two legs: 109,5; length of the foot: (62 2) mm; diameter of the foot: (47 2)
34、 mm; length of the metal leg: 32 mm; diameter of the metal leg: 25 mm; socket depth of the foot: 20 mm; free standing height tetrapod: (124 2) mm; material of the feet: polyurethane elastomer; hardness of the foot top: (75 5) shore. 4.2.3 Driving system The drum lies loose on rollers mounted on a su
35、pport and drive shaft. The drum is prevented from moving in its axial direction by smooth running wheels fixed between the shafts or by a suitable profile on the rollers. It is important that the axis of the drum rotation is horizontal, which should be checked by placing a spirit level along the upp
36、er surface of the drum when in position. The rotational frequency of the drum shall be (50 2) cycles per minute. A counter is incorporated in the system, so that the number of rotations of the drum can be recorded. The counter may be pre-set to stop the apparatus after a given number of revolutions.
37、 DIN EN 10303:2016-02 EN 1269:2015 (E) 6 NOTE Longer driving rollers can be used to rotate a number of drums at the same time provided that all the requirements of this standard are met. 4.3 Equipment common to both methods 4.3.1 Standard soil The soil shall have the following composition (% by mass
38、): Quartz silica: 88,30 %; Kaolin: 9,35 %; Yellow ferrous oxide: 0,20 %; Black ferrous oxide: 0,60 %; Paraffin oil: 1,55 %. The soil shall have following colourimetric characteristics: L: 46,5 1,5; a: 4,2 0,3; b: 11,5 0,5. Since the colourimetric characteristics of the soil change with time and expo
39、sure to light, the soil shall be kept in the dark and its colourimetric characteristics (L, a, b) shall be checked every 6 months against the specified tolerances. 4.3.2 Vacuum cleaner A household type apparatus shall be used, equipped with a smooth, approximately 2 500 mm2section nozzle having the
40、following characteristics: partial vacuum = (1 900 190) mm water column; air flow rate = (30 3) dm3/s 4.3.3 Large dimension grey scales A set of large dimension grey scales including half degrees according to ISO 105-A02. 4.3.4 Apparatus An observation device according to Clause 5 in EN 1471:1996. 5
41、 Sampling and preparation of the specimens 5.1 Sampling and selection of the specimens Take a representative sample of four different coloured samples from the commercial range of the floor covering in accordance with the methods given in ISO 1957. DIN EN 10303:2016-02 EN 1269:2015 (E) 7 5.2 Prepara
42、tion of the specimen 5.2.1 Method A From each sample to be examined, cut two test specimens in the shape of a quadrant having a radius of 350 mm. The edges of the quadrant are cut parallel with and at right angles to the direction of manufacture. One of the two specimens is kept as a reference speci
43、men for the evaluation. Mark the two specimens with an arrow on the back (e.g. the direction of production) to permit alignment in the same direction for assessment. The quadrants are fixed onto the support (dimensionally stable flat plastic disk) using two strips of double-sided adhesive tape laid
44、overlapping the joints. In the case of self-adhesive tiles place them on the support without any additional adhesive. 5.2.2 Method B From each sample to be examined, cut two test specimens of (640 190) mm. The length is taken in the direction of production. One of the two specimens is kept as a refe
45、rence specimen for assessment, the other one is used for the soiling test in the tetrapod-drum. Cover the long sides of this specimen with a 20 mm wide tape. 6 Conditioning Condition the test specimens in the standard atmosphere specified in EN ISO 139, for at least 24 h. 7 Procedure 7.1 Method A a)
46、 Clean the specimens using the vacuum cleaner (4.3.2) before placing them onto the castor chair apparatus. Place the soil distributor above the specimen. b) Weigh out 10 g of standard soil (4.3.1); rotate the support plate of the apparatus without lowering the castor device; carefully put the standa
47、rd soil into the inner sieve by means of a spatula, so that it is evenly distributed over the whole surface of the sieve. c) Vibrate the sieve so as to spread out the soil evenly over the whole surface of the specimen. d) Lower the castor apparatus with a total loading of 60 daN until it rests on th
48、e support and then rotate the plate 100 cycles without reversal so as to spread out the soil and make it penetrate. e) Raise the castors and remove the specimen support from the apparatus. f) Clean the specimen with the vacuum cleaner (4.3.2) using a forwards and backwards motion for 5 s in each dir
49、ection. Repeat this 10 times. Examine the treated specimen and if the soil is not distributed evenly on the specimen repeat the test with a new specimen. g) On the same specimens a second soil treatment shall be applied. Repeat all of the operation b) to f) by using the opposite direction of rotation in d). h) Remove the specimens from the support and assess the colour change g
