31、sional stability and curling after exposure to heat1 Scope This International Standard specifies a method fordetermining dimensional stabilityand curling of resilientfloor coverings, in the form of sheets and tiles,in linear dimensions after exposureto heat. 2 Terms and definitions Forthe purposes o
32、f this document, the followingterms and definitions apply.2.1 dimensional stabilityabilityofa resilient floorcoveringto retainits original dimensions after exposure to heat, under specified conditions2.2 curling verticaldeformation appearing on the specimen after exposure to a heat treatment, under
33、specified conditions2.3 domedreverse curlwhen centered, area ofspecimen that does not lie flat againstsupport plate 3 Principle 3.1DimensionalstabilityThe relative change in distance between marksora specific location on a testspecimen is measured beforeand after exposure to a heat treatment, under
34、specified conditions.Inthe caseoftiles,measurements may bemade using a blockand dialgauge assembly and marking of the test specimen is not necessarily required. 3.2Curling The verticaldeformations are measured in the testspecimen after the specified heat treatment. Test specimens are placed in an ov
35、en at an elevated temperature, after whichcurland dimensional stability are determined. In the case of domed material, turnthe testspecimen over to measure invertedorwiththe backofthe sample facing up. Measure curland mark appropriately as negative curl.

In operation,ensure that radiation from the heating element does not directly reach the test specimens orsupport plates.
37、4.2Support plates, of solid metal, e.g. aluminiumorstainless steel, of dimensions larger thanthe testspecimen and not lessthan1,5 mmin thickness. Ensurethat the support plates are kept smooth and polishedso thatsurface friction does not interfere with free shrinkage or growth of the testspecimens. T
38、he plates shall be flat and free of convex or concave warp. The shapes and dimensionsofthe apparatus specified in 4.1 and 4.2 shall be such that: a) curling can be measured without removing the testspecimens from the supportplates, except in the caseof domed material; b) the clearance between the pl
39、ates and the vertical walls of the oven is W 50 mm; c) the vertical clearancebetween the support platesand between the platesand theoven is W 100 mm. 4.3 Measuringdevice.4.3.1 Measuringequipment (for sheet or tile testspecimens): preferablyan optical bench, fornon-contactmeasurements.The equipment s

Cut out three (3), nominal 240 mm square testspecimens, at equal distance, from the sample material (see Figure 3). The distancebetween the outer edge of the sample and nearest edge of the
46、 testspecimen shall beat least 100 mm. The testspecimen edges shall be parallel/transverse to the direction of manufacture.
