The foam test is of interest when the glue is to be applied by special machines. Many of the physical tests (e.g. the methods are carefully followed consistent results are obtainable which will provide useful information both to the manufacturer and user. Small samples of glue rapidly change their moisture content in response to changes in atmospheric humidity. It is essential to keep the moisture waterproofstoragecontainersisrecommendedforthispurpose. If a consignment undergoes long delays in transit, the average moisture consumer. To avoid this problem causing unnecessary disputes, it is recommended that, when gel strengths or viscosities are reported, the results of moisture content tests should also be given, if an accurate comparison is required. Although the remaining tests listed in table 1 may are not significant and it is not necessary to report moisture contents for them. ili Copyright International Organization for Standardization Not for Resale
