Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. The distance from the end of the lap to the end of the jaws should be 63 mm 21? ASTM D determines the shear strength of adhesives for bonding metals when tested on a single-lap-joint specimen. A range may be prescribed for any variable by the manufacturer of the adhesive if it can be assumed by the test operator that any arbitrarily chosen value within such a range, or any combination of such values for several variables will be acceptable to both the manufacturer and the purchaser of the adhesive. Single-lap tests may be used for comparing and selecting adhesives or bonding processes for susceptibility to fatigue and environmental changes, but such comparisons must be made with great caution since different adhesives may respond differently in different joints.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D

Cut sheets astm d1002 the metals prescribed in 6. Perform the cutting operation so as to avoid overheating or mechanical damage to the joints Note 2. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to astm d1002 wide range of industries around the world. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell or shrink.

The maximum permissible length may be computed from the following relationship: Validating the specifications, value and safety of your raw materials, products and assets. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes. It shall be provided with a suitable pair of self-aligning grips to hold the specimen. The distance from the end of the lap to the end of the jaws should be 63 mm 21? The specimen failure should occur in the adhesive, and not in the substrate — thus the metal thickness and the length of the overlap may be adjusted as necessary.

Current edition approved Astm d1002. The astm d1002 and adhesive are likely to have different thermal and moisture coefficients of expansion. All edges of the metal panels and specimens which will be within or which will bound the lap joints shall be machined true without burrs or bevels and at right angles to faces and smooth rms max before the panels are surface-treated and bonded.

This rate of loading will be approximated by a free crosshead speed of 1. The test specimens are placed in the grips of a universal testing machine and pulled at astm d1002. Adhesive is applied based on manufacturer recommendations. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters. See Guide D for further discussion of the concepts relative to interpretation of adhesive-bonded single-lap-joints. The method of obtaining the thickness of the adhesive layer shall be described including procedure, location of measurements, and range of measurements.

It is recommended that the jaws of these grips shall engage the outer 25 mm 1 in. It should be stated whether this temperature is that of the astm d1002 or of the atmosphere at which the assembly is to be maintained.

The recommended metal thickness is 1.

The apparent shear strength measured with a single-lap specimen is not suitable for determining design-allowable stresses for designing structural joints that differ in any manner from the joints tested without thorough analysis and understanding of the joint and adhesive behaviors.

Lap Shear Strength of Adhesively Bonded Metal Specimens ASTM D1002

Last previous edition D — If you feel that your comments have not received a fair hearing astm d1002 should astmm your views known to the ASTM Committee on Standards, d100 the astm d1002 shown below.

These shall be cut from test panels prepared as prescribed in Section 7. However, individual specimens may be prepared if agreeable to the supplier or the purchaser of the adhesive. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.

Preparation of Test Joints 7. Assemble the sheets so that they will be held rigidly so that the length of the overlap astm d1002 be controlled, as indicated in Section 6, within 0. The misuse of strength values obtained from this test method as design-allowable stress values for structural joints could lead to product failure, property damage, and human injury. Apply the adhesive to a sufficient length in the area across 6.
