This is adapted for crack injection products ulated with polymer thermosetting binder. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. EN IS0 281 1-2, Paints and varnishes - Determination of density - Part 2 Immersed body plummet IS0 28 1 1 -2 1 997. 3 Test principle The total volumetric shrinkage is calculated as the percentage change in density when the polymer system at 21 2 O C cures to the final product also at 21 2 “C. The density after polymerisation curing is measured at 21 0,5 “C by measuring the buoyancy of the specimen immersed in silicone oil. 4 General requirements for testing - Apparatus 4.1 balance accurate to 0,001 g, a density measuring device, and suitable wire for suspending the specimen in silicone oil; 4.2 thermometer accurate to 0,2 “C and graduated at intervals of 0,2 “C or finer; 4.3 silicone oil bath of density Qsi at 21 k 0,5 “C; 4.4 test tube diameter 20 mm, length 180 mm in polyethylene or glass treated with a silicone release agent; 4.5 stopwatch; 4.6 desiccator; 4.7 temperature - controlled room or enclosure, capable of maintaining the sample at the recommended constant temperature. 4 Copyrght British Standards lnsttuton Reproduced by IHS under license with BSI - Uncontrolled Copy No reproduction or networking permtted without license from IHS Not for Resale 标准分享网 w w w .b z f x w .c o m 免费下载 w w w . b z f x w . c o m EN 12617-22OO4 E 5 Test procedure 5.1 Determination of the density of the material before polymerisation Since it is difficult to determine the density of resin systems that react at ambient temperature owing to their high reactivity and the exothermic heat evolved, determine separately the densities of the components of the resin, at 21 QB is the density of component B, in gram per millilitre; n is the mass of component A used for preparation of a specimen, in gram; nl, is the mass of component B used for preparation of a specimen, in gram. 5.2 Determination of the density of polymerized cured material Pour 25 A 5 g of the resin system as specified in 5.1 into the test tube. After allowing the correct time for polymerisation curing at 21 2 “C, leave to cool in a desiccator. When cool remove the polymerized specimen from the test tube. Weigh the specimen immediately in air MFSL then measure the apparent mass in silicone oil at 21 A 0,5 “C .LfFs .,,,. and weigh the suspension wire used for weighing ,IDL in air. Then remove as much as possible of the silicone oil adhering to the specimen, using filter paper, washing with petroleum ether1. Dry the specimen, for one hour, at 1 10 . I S L is the mass of the polymerized cured resin in air, in gram; .\/,F;D, is the apparent mass of specimen and suspension wire in silicone oil, in gram; .\11. is the mass of the suspension wire in air, in gram. 1 Take appropriate precautions by using organic solvents.
