This test method allows comparing the open time of several hot melt adhesives.

This test method is not intended to provide the open-time observed for a specific adhesive in a specific manufacturing operation. This test method can be used to compare the performance of adhesives which are represented to be identical or to rank the open-time of a group of hot melt adhesives.

1. Scope

1.1 This test method covers the manual determination of the open-time range of hot-melt adhesives under the stated conditions.

1.2 The values stated in SI units are to be regarded as the standard. The inch-pound units in parentheses are provided 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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
