Depending on their chemical base and their compositions sealants are available as single or multi-component systems. To make identification easy they shall be designated by the following symbols: Table 1 — Systems of cold applied joint sealants Material System Single component system S Multi components system M

Where a primer is part of the system recommended by the manufacturer, then specimens prepared for the appropriate performance tests shall include a primer. The manufacturer shall always specify whether a primer is required or not. 5 Requirements 5.1 General For testing a cold applied sealant, the uniform method of conditioning (EN 28340:1990, Method B) shall be applied for test procedures where this conditioning method is stipulated by choice. A test specimen shall fail if, after the test extension, the sum of adhesive and cohesive failures exceeds 5 %. Test specimens, which pass the first extension, shall fail in subsequent extensions if the sum of additional adhesive or cohesive failures exceeds 10 %.
