Standard Test Method for Field Pull Testing of an In-Place Wall Assembly with an Exterior Insulation and Finish System (EIFS) or EIFS with Drainage System

Importancia y uso:

4.1 The purpose of this test method is to assess the installation adequacy and the overall effects of service-related deterioration (moisture, etc.) on the wall assembly as opposed to small localized areas of degradation. Resistance to pull testing as determined by this test is used as one of the factors in evaluating the assembly on a specific project. The values obtained by this test method are not purported to be representative of the actual wind load capacity or other structural properties of a specific installation, but may be helpful in assessing such load capacities.

4.2 Since this test is used for field evaluation of existing facilities, load results obtained from this test must be interpreted based on sound engineering practice, applicable building regulations, and codes having jurisdiction. It is the discretion of the test specifier to directly utilize the results derived by this test method, or else to utilize the test results with an appropriate factor of safety to obtain acceptable working loads for each project.

4.3 This method is intended for use on test specimens occurring or installed on existing buildings. The loss of outward wind load resistance of a wall assembly after exposure to moisture and other weather conditions may compromise the ability of the cladding or other wall components to perform adequately in place. This test method does not provide any means by which the test results may be generalized to the larger wall area. Such efforts should be based on experience and engineering judgement.

4.4 The manner in which the test load is applied may affect the load capacity obtained from using this test method. A discussion of various load application techniques and their effects is given in Appendix X1.
