A more quantitative test for adhesion is the pull-off test where a loading fixture, commonly called a dolly or stub, is affixed by an adhesive to a coating. This International Standard describes methods for determining the adhesion by carrying out a pull-off test on a single coating or a multi-coat system of paint, varnish or related product. I recommended installing the anchors and conducting a pull test, if the pull test is good no other action is necessary. ASTM D4541 Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers . 12mm plaster is the desired thickness. 0000006083 00000 n Figure11shows the batched back test area and the good adhesion between plaster and panel support. The first layer applied should be cured for a day before applying the subsequent coats. Get the plastering specifications like lime finish, trowel finish, sponge finish, rough plaster and zone of application clarified from architects. SIGN ME UP. :k��6�Pti��q�������%�����駩cs� ��1��A�ͩAg� Pull-Off Tests. By use of a portable pull-off adhesion tester, a load is increasingly applied to the surface until the dolly is pulled off. Grooves and mortar bands should be given while the plaster is wet. This part of ISO 16276 also specifies suitable equipment and defines inspection areas, sampling plans and acceptance/rejection criteria. A more quantitative test for adhesion is the pull-off test where a loading fixture, commonly called a dolly or stub, is affixed by an adhesive to a coating. 4. 0000001291 00000 n Curing of Plaster. Good acceptance criteria as discussed above should establish boundary so that the developers know how much to code and where to stop. Test the specimen within 7 days after coring. ADMET material testing systems perform accurate and reliable tension tests / tensile tests. By use of a portable pull-off adhesion tester, a load is increasingly applied to the surface until the dolly is pulled off. These test methods have been found useful in comparing the adhesion behaviour of different coatings. The bond strength between the UHPC substrate and the UHPC top layer was evaluated by shear tests and pull-off tests with promising results. 0000007267 00000 n Surface. Ensure all plastered surfaces are cured for the entire recommended period. Test area to be patched back. Acceptance criteria could establish a boundary that helps team members to understand what’s included and what’s excluded from the scope of the user story. )���a��#� 5��h endstream endobj 23 0 obj<> endobj 24 0 obj<> endobj 25 0 obj<> endobj 26 0 obj<> endobj 27 0 obj<> endobj 28 0 obj<> endobj 29 0 obj<> endobj 30 0 obj<> endobj 31 0 obj<>stream The information provided should not be used as a substitute for professional services.

FORE W 0 R D 0.1 This Indian Standard ( Part I ) was adopted by the Indian Standards Institution on 20 November 1967, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Civil Engi­ neering Division Council. The shear tests are oftentimes more definitive because they better replicate the way in which coatings fail. The Laboratory of Building Physics (LFC-FEUP) has used the pull-off test results in several cases to Rig Manager to discuss procedures with pressure testers. If more, the tests of the sample are invalid. The concrete shall be acceptable with the strength requirements when both the following condition are met for all grades of COATING ADHESION TESTING. Overall view after adhesion pull off test conducted. Measure the ceiling from this level – it should be even at all points. All mortar waste stuck to walls, floor, and MS sheet shall be cleared after the day’s work. taken up with a view to updating the methods of test in line with the current knowledge on the subject. Figure 11. 0000003400 00000 n Review JSA for Pressure Testing BOP. 0000001494 00000 n After plastering check the surface for undulations using halogen lamps. Mix mortar on MS sheet using Measuring Box (Farma) for volumetric batching. Grooves and mortar bands should be given while the plaster is wet. Generally speaking, for drywall, a safe moisture content (%MC) would be less than 1% MC. Several standards frame the application of this test and its results interpretation. The result of the pull off test is 5 MPA. However, future activities need to include more systematic investigations, in particular with regard to the surface properties of the UHPC substrate. 3.5 Film adhesion test The coating film adhesion shall be tested in ac-cordance with method “B” of ASTM D3359-02, “Standard Test Method for Measuring Adhe-sion by the Tape Test.” A total of (11) parallel cuts are made with a sharp instrument, 0.039" (1 mm) apart in both a vertical and horizontal direction forming a grid. A test-based strategy is no longer recommended to determine when to discontinue home isolation, except in certain circumstances. No more than 50% of the lead width or 0.50 mm (.020") whichever is less. Apart from revising the methods of test already covered in the first version of this standard, the revision incorporates methods of test for fibrous gypsum plaster boards covered by IS : 8273-1976-. We have applied primer, intermediate and top coat after we conduct pull off test after 2 weeks. Download Method Statement For Plastering Works Res., 1992, 44, No. 3.2.9.10 three-coat work—application of plaster in three successive coats with time between coats for setting or drying, or both. 0000008419 00000 n Figure 12. Specimens breakdown. Once the plaster is hard and set, curing must be started and continued till 7 days. This strip has to be plastered and cured for a minimum of 3 days before the entire wall is plastered. Looking For An Enterprise Test Authoring Platform? Check for smooth finish using spirit levels for undulations, cracks and evenness/straightness in vertical and horizontal directions. Note it gives the allowable deflection based on a fractional span quantity, so a larger denominator will yield less deflection. 0000001036 00000 n Do not plaster for a thickness of more than 15mm. Several standards frame the application of this test and interpretation of its results. The aluminum template for openings (sometimes we use sand to cover the electric holes) should be available at the site. Scrum is a technique that enables the software development team to work with the agile approach and user stories to solve the most sophisticated development process. All cut-outs such as fan, junction box, electrical box and skirting line should be finished to perfection. Ensure plastered surface is cured for the entire recommended period. The test determines the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached. Fit for Duty check on all hands. JOTU PHOTOGRAPH ADHESION PULL OFF TEST . J.H. Unlike the other methods, this method maximizes the tensile stress, therefore results may not be comparable to the others. Pull-Off Tests. The criterion of user story acceptance not only informs the product behavior in happy path scenarios, it also guides the user experience when things don’t work as intended. All surfaces in concrete should be hacked (80 hacks per SQ. Yellow light is thrown on the plastered wall from one side shows undulations, if any, rectify immediately while the plaster is still fresh.
