Field- Adhesion Testing: Field test joint - sealant adhesion to joint substrates as follows: <br />Extent of Testing: Test completed and cured sealant joints as follows: <br />a. Perform 5 tests for the first 500 feet (150 m) of joint length for each kind of sealant <br />and joint substrate. <br />b. Perform 1 test for each 500 feet (150 m) of joint length thereafter. <br />2. Test Method: Test joint sealants according to Method A, Field- Applied Sealant Joint <br />Hand Pull Tab, in Appendix X1 in ASTM C 1193 or Method A, Tail Procedure, in <br />ASTM C 1521. <br />a. For joints with dissimilar substrates, verify adhesion to each substrate separately; <br />extend cut along one side, verifying adhesion to opposite side. Repeat procedure <br />for opposite side. <br />Inspect tested joints and report on the following: <br />a. Whether sealants filled joint cavities and are free of voids. <br />b. Whether sealant dimensions and configurations comply with specified <br />requirements. <br />C. Whether sealants in joints connected to pulled -out portion failed to adhere to joint <br />substrates or tore cohesively. Include data on pull distance used to test each kind <br />of product and joint substrate. Compare these results to determine if adhesion <br />passes sealant manufacturer's field- adhesion hand -pull test criteria. <br />4. Record test results in a field- adhesion -test log. Include dates when sealants were <br />installed, names of persons who installed sealants, test dates, test locations, whether joints <br />were primed, adhesion results and percent elongations, sealant fill, sealant configuration, <br />and sealant dimensions. <br />5. Repair sealants pulled from test area by applying new sealants following same procedures <br />used originally to seal joints. Ensure that original sealant surfaces are clean and that new <br />sealant contacts original sealant. <br />B. Evaluation of Field - Adhesion Test Results: Sealants not evidencing adhesive failure from <br />testing or noncompliance with other indicated requirements will be considered satisfactory. <br />Remove sealants that fail to adhere to joint substrates during testing or to comply with other <br />requirements. Retest failed applications until test results prove sealants comply with indicated <br />requirements. <br />3.5 CLEANING <br />A. Clean off excess sealant or sealant smears adjacent to joints as the Work progresses by methods <br />and with cleaning materials approved in writing by manufacturers of joint sealants and of <br />products in which joints occur. <br />JOINT SEALANTS 079200-8 <br />
