Check for undulations and unevenness by using spirit levels. OJOTUN PHOTOGRAPH ADHESION PULL OFF TEST . Unlike the other methods, this method maximizes the tensile stress, therefore results may not be comparable to the others. Pull off Stress (N/mm 2) 0000009050 00000 n 4. Fix button mark on the surface to be plastered keeping the minimum thickness. The Laboratory of Building Physics (LFC-FEUP) has used the pull-off test results in several cases to For each test, 5 spots are to be randomly selected. �yi�Tb��y��|c��� ���>�~�b���,��i����ø�k��'�����?���HpJw 3�]r�Z��DA��A�a�k�lda�i��H�6bs/Z�Ű�E�-�9�MTx�݅V�2���%ys��2)���as��g�2Q�d���]hq���^�p�Da���^���as��I�����.���aw3�;m��(L��? Table 4: Acceptable Solder Criteria for Gull Wing Components. 0000002065 00000 n Mix shall be generally CM 1:4 for ceiling and 1:6 for wall plastering. General Test Procedures. The pull-off force, F, is divided by the cross-sectional area of the partial core to obtain the pull-off strength fp: 2 4 p F f d where d is the diameter of the partial core. Complex: Acceptance criteria is complex, includes jargons and technical details. Variability in one or more of these attributes can reduce the measured pull force. Is this acceptable? Pull-Off Tests. All cut-outs such as fan, junction box, electrical box and skirting line should be finished to perfection. x�b``�d``nb`a`�ug�g@ ~�+s|``�Y�f.���((((���hl��s10=� Acceptance quality level. The aluminum template for openings (sometimes we use sand to cover the electric holes) should be available at the site. I recommended installing the anchors and conducting a pull test, if the pull test is good no other action is necessary. 5. time to the Operator for the test. Help us to share this . Overall view after adhesion pull off test conducted. Write down the date of work in the paint on the element for plastering, concrete & monitor the curing accordingly. The adhesion of a coating or several coated sample of any paint product is measured by assessing the minimum tensile stress needed to detach or rupture the coating perpendicular to the substrate. 0000001291 00000 n With The Gauge Platform, You Can Create, Customize, and Deliver High-Stakes Tests That Meet Your Organization’s Unique Needs . Create work items such as bugs, tasks, and test cases directly from the extension. 3M introduces Firedam Spray for construction joints to meet ASTM 1399 test criteria.

I would like to ask for the acceptance criteria of pull off testing using dolly (Hydraulic Adhesion Tester)? The procedures given in this part of ISO 16276 are based on methods used with different types of pull-off test equipment. The bars are #7 using Hilti RE 500. A test-based strategy is no longer recommended to determine when to discontinue home isolation, except in certain circumstances. trailer <<11aa7eb2fd8f11d9871f0003938c0c30>]>> startxref 0 %%EOF 16 0 obj<>stream IS 1542 (1992): sand for plaster [CED 5: Flooring, Wall Finishing and Roofing] Indian Standard SAND FOR PLASTER - SECIFICATION / Second Revision J Second Reprint FEBRUARY 1999 UDC 691.223:691.55 @ BIS 1992 BUREAU OF INDIAN STANDARDS MANAK BHAVAN, 9 BAHADUR SHAH ZAFAR MARC3 NEW DELHI 110002 J&J 1992 Wcibql . 0000000836 00000 n The test determines the greatest perpendicular force (in tension) that a surface area can bear before a plug of material is detached. impact area and pull off sharply. Calculation of Compressive Strength of Concrete Core. BOND-TEST (a) Failure in substrate (b) Bond failure (c) Failure in overlay The types of failures that can occur in a BOND-TEST are illustrated above: (a) failure in the JOTU PHOTOGRAPH ADHESION PULL OFF TEST . ADMET material testing systems perform accurate and reliable tension tests / tensile tests. Overall view before adhesion pull off test conducted. 14 0 obj<> endobj xref 14 27 0000000016 00000 n By use of a portable pull-off adhesion tester, a load is increasingly applied to the surface until the dolly is pulled off. Users can file a bug to report an issue with the product, or create a task that indicates a new work requirement. Note it gives the allowable deflection based on a fractional span quantity, so a larger denominator will yield less deflection.
