ASTM F1362-13

Standard Test Method for Shear Strength and Shear Modulus of Aerospace Glazing Interlayer Materials

SIGNIFICANCE AND USE
5.1 The basic material properties obtained from this test method can be used in the control of the quality of interlayers, in the theoretical equations for designing laminated transparencies, and in the evaluation of new interlayers.
SCOPE
1.1 This test method covers the determination of the shear strength and shear modulus of interlayer materials that are restrained by relatively high modulus plies in laminated transparencies. This test method can be used with single or multiple plies of the same interlayer materials.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
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 document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Terminology
3.1 Definitions:
3.1.1 adherend—relatively higher modulus plies that restrain interlayer materials.
3.1.2 shear modulus—the ratio of the shear stress to the corresponding shear strain for the initial straight-line portion of the
curve.
3.1.3 shear strength—the maximum shear stress existing in the interlayer prior to failure. Represents the shear strength of the
system either as a cohesive or adhesive failure mode.
4. Summary of Test Method
4.1 Torsional shear forces are applied to the interlayer through a circular section that produces a peripherally uniform stress
distribution. The maximum stress in the interlayer at failure represents the apparent shear strength of the interlayer. By measuring
the interlayer strain as a function of load, a stress-strain curve can be established. The test specimen should be made from the same
materials that are to be used in production, and production processes should be used when applicable. It is also possible to fabricate
specimens from the finished/formed transparency.
5. Significance and Use
5.1 The basic material properties obtained from this test method can be used in the control of the quality of interlayers, in the
theoretical equations for designing laminated transparencies, and in the evaluation of new interlayers.

6.1 Testing Machines—Machines used for shear testing shall conform with the requirements of Practices E4. The loads used in
determining shear strength shall be within the loading range of the testing machine as defined in Practices E4.
6.2 Torsional Shear Apparatus—The torsional shear jig should apply a torsional shear load to the specimen without inducing
bending, peeling, or transverse shear stresses in the test section. Loading can be accomplished with torsion-test equipment or by
means of a jig that can be used in a universal testing machine. A jig is shown in Fig. 1 (see Practice F734) and Figs. 2 and 3 show
the adaptations required for the various specimens.
