1. Scope
1.1 This test method describes the requirements for sample preparation and tensile testing of overlap splices formed with fiber-reinforced polymer (FRP) composite materials commonly used for strengthening of structures made of materials such as metals, timber, masonry, and reinforced concrete. The objective of this test method is to determine the apparent shear strength of an overlap splice joint through direct tension. This test method is often used to determine the length of the overlap splice needed to induce stock-break failures. This test method applies to wet lay-up and preimpregnated FRP material systems fabricated on site or in a laboratory setting. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
This test method will accompany the infrastructure laminate tension method and is commonly used to determine required splice lengths in FRP composite repair laminates.
