BSI STANDARDS - Summary

It should be noted that a number of BSI standards have been adopted as EN and ISO standards and have a dual numbering system (i.e. BS EN ISO). These standards have been included on the ISO Standards List.

Mechanical

Cleavage Tests

BS 5350-C1 (1986): Methods of Test for Adhesives. Adhesively Bonded Joints: Mechanical Tests. Determination of Cleavage Strength of Adhesive Bonds

This Part of BS 5350 describes a method for the assessment of the cleavage strength of adhesive bonds between rigid materials under specified conditions.

Peel Tests

BS 5131–1.2 (1991): Methods of Test for Footwear and Footwear Materials. Adhesives. Resistance of Adhesive Joints to Peeling

This part of BS 5131 describes a method for measuring the strength, in terms of resistance to peeling, of a bond between two sheet materials that have been bonded together. The method is applicable to a great variety of combinations of upper materials, soling materials and adhesives, where at least one adherend is flexible.

Note:    The purpose of the method is to test joints rather than to compare adhesives. As a consequence, unlike BS 5131–1.1, no recommendations are given concerning appropriate adherends. The two adherends are pulled apart at a constant rate; the test specimen will invariably fail, and it is the forces causing test specimens to fail and the nature of the failure that are under investigation.

BS 5131–1.3 (1991): Methods of Test for Footwear and Footwear Materials. Adhesives. Preparation of Test Assemblies Using Adhesives (Other than Hot Melt Adhesives) for Heat Resistance (Creep) and Peel Tests

This section of BS 5131 describes methods for preparation of the test assemblies required by BS 5131–1.1 and BS 5131–1.2 for determination, respectively, of the resistance of bonded joints to heat (creep tests) and to peeling. BS 5131–1.3 includes methods for preparation of the adhesive and of the adherends. It covers most types of bonding used in the footwear industry except hot melt adhesive bonds, which are covered in BS 5131–1.7.

The types of bonds include stuck on bonds made by the use of applied adhesives (both solvent-based and water-based), injected-on bonds using thermoplastic sole materials, e.g. polyvinylchloride (PVC), thermoplastic rubber and moulded-on direct vulcanised rubber sole bonds. The methods of preparation are applicable to a wide variety of combinations of materials, but the peel and creep tests of BS 5131–1.1 and BS 5131–1.2 require at least one adherend to be flexible.

BS 5131–1.6 (1979): Methods of Test for Footwear and Footwear Materials. Adhesives. Recommended Environmental Storage Conditions for Adhesive Joints Prior to Heat Resistance or Peeling Tests

The performance of adhesive bonds in footwear may deteriorate in storage or in wear because of the adverse effect of environmental conditions, such as natural ageing or wetting. This part of BS 5131 describes a number of environmental storage conditions which may be used in the laboratory for the treatment of prepared adhesive joints in order to simulate the deterioration, which may occur in practice.

BS 5131–1.7 (1991): Methods of Test for Footwear and Footwear Materials. Adhesives. Preparation of Test Assemblies Using Hot Melt Adhesives for Heat Resistance (Creep) and Peel Tests

This part of BS 5131 describes methods for the preparation of test assemblies with various forms of hot melt adhesive by methods which simulate their use in shoe manufacturing for sole attaching, adhesive lasting and the laminating upper components.

Where the test assemblies are prepared by indirect bonding, they are intended for use in either the resistance to heat (creep test) described in BS 5131–1.1 or the resistance to peeling test described in BS 5131–1.2. However, where the test assemblies are prepared by direct bonding, they are intended for use in BS 5131–1.2 only, since the temperature given in BS 5131–1.1 is not sufficient to soften the adhesive.

The methods of preparation are applicable to a wide variety of combinations of adhesives and materials, but the peel and creep tests of BS 5131–1.1 and BS 5131–1.2 require at least one adherend to be flexible.

BS EN 28510–1 (1993) or ISO 8510 Part 1 (1990): Adhesives—Peel Test for a Flexible-Bonded-to-Rigid Test Specimen Assembly—Part 1: 90 Degree Peel

This international standard is particularly suitable for use with less flexible adherends for which a 180° peel test is not suitable because the adherends crack, break or delaminate. A bonded assembly of two adherends is prepared using the adhesive under test. The adherends are then pulled apart at a steady rate, starting at the open end of the bond in such a way that separation occurs progressively along the length of the bonded adherends. The force is applied approximately normal to the plane of the bond, through the separated part of the flexible adherend.

BS EN 28510–2 (1993) or ISO 8510–2 (1990): Adhesives—Peel Test for a Flexible-Bonded-to-Rigid Test Specimen Assembly—Part 2: 180 Degree Peel

This international standard is suitable for use with less flexible adherends. The principle consists in preparing a bonded assembly of two adherends, using the adhesive under test. The adherends are then pulled apart at a steady rate, starting at the open end of the bond in such a way that separation occurs progressively along the length of the bonded adherends. The force is applied substantially parallel to the plane of the bond, through the separated part of the flexible adherend.

Shear Tests

BS 5350 Part C5 (2002): Methods of Test for Adhesives. Determination of Bond Strength in Longitudinal Shear for Rigid Adherends

This part of BS 5350 describes the method for testing adhesives using rigid adherends that can be produced to the required dimensional tolerances and that will withstand the forces applied to them. It is not normally applicable to the testing of joints between identical pieces of wood for which there are other, specific, standards, but may be used where wood is one adherend of an asymmetric assembly or where particular adhesives are not catered for by the specific standards. The method described in this part of BS5350 is applicable to all types of adhesives. Although primarily intended for use in normal ambient conditions, the basic method is also applicable to testing under a wide range of temperatures and other environmental conditions.

Note 1: No account is taken of other mechanical properties of the adhesives or adherends that can affect the validity or usefulness of the test.

Note 2 The use of a particular adherend to test an adhesive does not necessarily imply that adhesives is the one most suitable for the adherend.

Note 3: This method of test is intended for ranking and quality control of adhesives and not for obtaining data for design purposes.

BS 5350-C15 (1990): Methods of Test for Adhesives. Adhesively Bonded Joints: Mechanical Tests. Determination of Bond Strength in Compressive Shear

This Part of BS 5350 describes a procedure for determining the bond strength of a double lap joint by subjecting the test piece to a compressive force. The method is applicable to all types of adhesive. Although primarily intended for use under ambient conditions, the basic method is also applicable to testing under a wide range of temperatures and other environmental conditions. The method requires rigid adherends produced to specified dimensional tolerances. This test is intended for ranking and quality control of adhesives and not for obtaining data for design purposes.

Note:    The test may still be useful for research or control purposes even if the strength of the bond exceeds the strength of the adherend.
