Test methods for building sealants Part 20. determination of contamination1 ScopeThis part of GB/T 13477 specifies the method for determining the contamination of building sealants. This part applies to the determination of the contamination of the porous substrate (such as marble, limestone, gravel or granite) by the sealing material in the construction joint, Where Test Method A is suitable for the determination of contaminants under compression conditions. Test Method B is applicable to the determination of contaminants under non-compressed conditions test. Note. This test method is based on the sealing material within the material exudation of the porous substrate surface of the possibility of early pollution evaluation, the test results only represent Test sealing materials and test substrates can not be used to infer other formulations of sealing material or other porous substrates. Accelerated test period, if sealed The material does not cause contamination or discoloration of the substrate, does not mean that the test seal material after long-term use, will not make the porous test substrate pollution or discoloration. The experience of multiple countries shows that the use of similar test methods to compress the specimen can further accelerate the generation of pollution.2 normative reference documentsThe following documents are indispensable for the application of this document.

The sealing material is filled between two porous substrates to form a test piece. The test piece is compressed (or not compressed) and subjected to heat and/or low temperature and / Or light radiation accelerated aging treatment, aging test after the evaluation of test pieces. Measure the maximum and minimum contamination by visualizing the changes in the surface of the substrate Dyeing width and pollution depth, recording the outer surface of the substrate and the body of the internal pollution phenomenon.
