A. Field -Adhesion Testing: Field test joint -sealant adhesion to joint substrates as <br />follows: <br />1. Extent of Testing: Test completed elastomeric sealant joints as follows: <br />a. Perform 10 tests for the first 1000 feet (300 m) of joint length for each type of <br />clastomeric sealant and joint substrate. <br />b. Perform 1 test for each 1000 feet of joint length thereafter or 1 test per each <br />floor per elevation. <br />2. Test Method: Test joint sealants according to Method A, Field -Applied Sealant <br />Joint Hand Pull Tab in Appendix X1 in ASTM C 1193, as appropriate for type of joint - <br />sealant application indicated. <br />a. For joints with dissimilar substrates, verify adhesion to each substrate <br />separately; do this by extending cut along one side, verifying adhesion to <br />opposite side. Repeat procedure for opposite side. <br />3. Inspect joints for complete fill, for absence of voids, and for joint configuration <br />complying with specified requirements. Record results in a field -adhesion -test <br />log. <br />4. Inspect tested joints and report on the following: <br />a. Whether sealants in joints connected to pulled -out portion failed to adhere <br />to joint substrates or tore cohesively. Include data on pull distance used to <br />test each type of product and joint substrate. Compare these results to <br />determine if adhesion passes sealant manufacturer's field -adhesion hand - <br />pull test criteria. <br />b. Whether sealants filled joint cavities and are free of voids. <br />C. Whether sealant dimensions and configurations comply with specified <br />requirements. <br />5. 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, <br />whether joints were primed, adhesion results and percent elongations, sealant fill, <br />sealant configuration, and sealant dimensions. <br />6. Repair sealants pulled from test area by applying new sealants following same <br />procedures used originally to seal joints. Ensure that original sealant surfaces are <br />clean and that new sealant contacts original sealant. <br />B. Evaluation of Field Test Results: Sealants not evidencing adhesive failure from <br />testing or noncompliance with other indicated requirements will be considered <br />satisfactory. Remove sealants that fail to adhere to joint substrates during testing or to <br />comply with other requirements. Retest failed applications until test results prove <br />sealants comply with indicated requirements. <br />07900-10 <br />
