5、prepared as normally used in production consisting of a bonded insert assembly or a portion of a bonded insert assembly. A suitable gripping fixture shall be bonded to the front and rear of the insert assembly. 4 Test procedure 4.1 Setup Using suitable equipment, an axial tensile load shall be appli
6、ed to the test specimen. Unless otherwise specified, the load shall be sufficient to cause a stress of 689 kPa I35 kPa (100 psi f 5 psi) to the insert assembly bond. The actual axial load required is determined by muitiplying the available bond surface area of the test joint by the required stress.
7、Unless otherwise specified, for a bonded connector insert assembly, the load shall be increased at a minimum rate of 0.45 kilogram per second (1 pound per second) until the required load is reached. Unless otherwise specified, the required load shall be maintained for a minimum of 30 seconds. 4.2 Re
8、quirements A failure is identified by visual observation (unless otherwise specified? up to 3x magnification) of separation or cracks at the bond joint while the required max. load is applied. If a failure occurs, indicate cohesive (substrate fails rather than adhesive)? adhesive or indeterminant fa
