ASTM E2359-13 (R2018) pdf free download.Standard Test Method for Field Pull Testing of an In-Place Exterior Insulation and Finish System Clad Wall Assembly.
1.1 This test method covers a procedure to determine the resistance of a section of the exterior insulation and finish system (EIFS) to outward loads imposed on an existing exterior wall assembly that has been in place on the building for an unspecified period of time. It is destructive in nature within the localited areas tested and requires appropriate repair of the EIFS cladding and sheathing OflCC the test procedure has been completed. This test procedure utilizes mechanical methods to obtain information, which may be helpful in evaluating the natural application of negative wind loads on the EIFS assembly. Some variability of results should be anticipated within the wall assembly tested due to differences in installation procedures. exposure. or abuse subsequent to application.
1.2 This test method is suitable for use on cladding assemblies that have been in place a short time (new construction), as well as for longer periods in order to evaluate detrimental effects on the EIFS lamina. insulation attachment, substrate integrity, and auachments after exposure to weather and other environmental conditions. It is not intended to evaluate the performance of structural framing. Test results on any particular building may he highly variable depending on specimen location and condition, and are subject to interpretation by the test specifIer.
1.3 The values stated in either SI units or inch-pound units are to he regarded separately as standard. The values stated in each system may not he exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
4. Significance and Use
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 EIFS 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 EIFS 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 ot a specific EIFS clad wall installation. hut 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 appropr ate 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 an EIFS wall assembly after exposure to moisture and other weather conditions may coin- promise 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 he generalized to the larger wall area. Such etlorts should he based on experience and engineering judgement.ASTM E2359 pdf download.
