35、deformation appearing on the specimen after exposure to a heat treatment, under 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

36、 a testspecimen is measured beforeand after exposure to a heat treatment, under 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 tes

37、tspecimen after the specified heat treatment. Test specimens are placed in an oven 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 ma

39、ed4 Apparatus 4.1 Oven, thermostaticallycontrolled and ventilated, capable of beingmaintained at a uniformtemperature of 80 2 C. In operation,ensure that radiation from the heating element does not directly reach the test specimens orsupport plates. 4.2Support plates, of solid metal, e.g. aluminiumo

40、rstainless 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. The plates shall be flat and free of convex or conc

41、ave 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 plates and the vertical walls of the oven is W 50 mm

42、; 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 shall have arange of at least 200 mmand a precision

43、 of 0,02mm. For manytypesofoptical benches, take care that the test specimen is properly seated against the base horizontal index guide when a specific measurement is being taken. Test specimens with concave or convex edges can be read incorrectly. 4.3.2 Micrometer (for sheet or tiletestspecimens),
