7、y to Standard Field Test Procedure for Determining the Mechanical Uplift Resistance of Insulation Adhesives over Various Substrates This Commentary consists of explanatory and supplementary material designed to help the user understand the requirements of the Standard through brief explanations of t
8、he reasoning employed in arriving at these requirements and is not considered a part of the ANSI standard. This standard is intended primarily for situations when an existing roofing system is being replaced or recovered and the general condition of the substrate is in doubt. This procedure, however
9、, is also applicable to new construction. CIII. Equipment (See Table A) Examples of appropriate pull testers are: COMTEN HYDRAJAWS CIV.A Test Area Tests should also be performed in areas where the roof may have been damaged or where water or other chemicals have infiltrated the roof system. These el
10、ements may have caused the roof deck or other components to deteriorate and cause lower pull values. (See Figure A) CIV.B Sample Size CB. Other sized plates may be used, however the data from tests using other than the 2 x 2 plate may not be consistent with data from the standard test specimen. Spec
11、imen size shall not be smaller than 2 times the on center spacing of the adhesive beads. (See Figure B) CIV.E Temperature of test The insulation adhesive manufacturer should be consulted concerning the application temperature limitations of the adhesive. Certain deck types (gypsum, cementitious wood
12、 fiber, or lightweight insulating concrete) may be affected by free water. Pull values obtained over decks in a frozen state may be elevated and therefore unreliable. CIV.K.c Determination of failure Failure could occur at the substrate/first layer intersection or any other subsequent adhered inters
13、ections. It could also occur within the insulation itself, such as the facer lifting off or the core separating, or failure of the substrate. Separation of the test specimen from the plywood shall not be considered a failure of the adhesive. The value should still be recorded as it may exceed the de
14、sign value for the specific project. CIV.K.e The lowest test value should be used as the design load resistance value, unless it is shown to be an anomaly. On certain projects, it may be necessary to perform additional pull tests beyond the minimum number required. This includes, but is not limited
15、to, occasions when: pull values vary significantly tests are performed in decks that are inherently less consistent such as lightweight insulating concrete, cementitious wood fiber, and gypsum there exist multiple damaged or questionable areas local building codes require additional tests roofs are
16、subject to high wind loading If there are anomalies in pull values, the deck should be inspected by a qualified professional to determine the cause. CIV.O The actual instrument readings reflect the tare weight + the pounds (kN) of force resisted by the tested assembly. Tare weight is the weight of t
17、he plate or plywood and the means used to connect the test sample to the load cell. Actual pressure calculations are made by subtracting the tare weight from the instrument reading and dividing that number by the total area of the sample size tested. For example: On a 24” x 24” (0.6096m x 0.6096m) (
18、4 sq. ft.) sample, if the tare weight is 10 lbs. (0.0445kN) and the instrument reading is 1010 lbs. (4.4927kN), the calculated uplift resistance of the assembly is (1010 lbs 10 lbs) / 4 ft2 = 250 psf (4.4927kN 0.0445kN) / 0.3716 sq. m. = 11.97 KPA) Approved May 16, 2005 ANSI/SPRI IA-1 2005 (4) Copyr
19、ight 2005 by SPRI. All Rights Reserved Personnel A person who has been trained in the pull test procedure should perform the tests. A representative of the building owner should be present to witness the tests and verify the values. A roofing professional should also be present to repair the test ar
20、eas and return the roof area to a watertight condition. Cautions See Commentary CIV.E Deck Loading This test does not indicate the suitability of the existing roof (if being recovered), the deck or the decks ability to withstand the uplift loads calculated by this procedure. A structural engineer or
