The document specifies a method for evaluating the adhesion of sealants with a minimum elongation at break of 25 % (according to ISO 8339, Method A or B) on various substrates. This test method can be used for one-component and multi component sealants. This method is typically used for elastic sealants but can be also used for plastic sealants. For plastic sealants, the test can be more difficult and needs to be carried out by experienced technicians. This test is used to judge the adhesion of construction sealants in combination with cleaners, activators and/or primers on various substrates when exposed to a peeling force and also after different aging conditions. An adhesion test according to this document can also be conducted for process monitoring and quality assurance accompanying production. The test method described in this document is not intended to replace any adhesion cohesion test methods specified in ISO 11600.

This document specifies a method for determining the staining of porous substrates (e.g. marble, limestone, sandstone or granite) by sealants used in building construction. The method evaluates the likelihood of a sealant causing an early stain on a porous substrate due to exudation of materials from the sealant. The outcome of the test is specific to the tested sealant and tested substrate and cannot be extrapolated to other sealant formulations or other porous substrates. During this accelerated test, if the sealant does not stain or discolour the substrates, it does not mean that the tested sealant will not stain or discolour the tested porous substrate over a longer time period.

This International Standard specifies the types and classes of elastic sealants used in building construction pedestrian walkways according to their performance characteristics. Sealant may be either non-sag or self-leveling as declared by the manufacturer. Areas of application are floor joints which have been designed. Chemical containment, cold applied joint sealants for concrete pavements to be used in roads, airfields, and sewage treatment plants are excluded. Local regulations may be required in addition to this International Standard based on local laws and codes.

Amends the last sentence of clause 4 (Principle) and deletes the last two lines of clause 9 (Test report) and replaces them by new text.

The sealants are also exposed to water or humidity, and to elevated temperature. The principle of the method specified is preparing test specimens and reference specimens in which the sealant to be tested adheres to two parallel contact surfaces, submitting the test specimens to the simultaneous influence of artificial light, water or humidity and elevated temperature under defined conditions, extending test specimens and reference specimens to a defined width and, after maintenance of the extension for a defined time, recording any breaks in adhesion or cohesion.
