ASTM D899-00(2013)
(Practice)Standard Practice for Applied Weight Per Unit Area of Liquid Adhesive
Standard Practice for Applied Weight Per Unit Area of Liquid Adhesive
SIGNIFICANCE AND USE
4.1 For the bonding of adherends, the amount of adhesive present is critical and it is important to understand that this practice does not ensure sufficient adhesive is present on the adherend surface.
4.2 This practice can be used to supplement industry uses such as that of visually checking the spread or the use of mil-thickness gages.
4.3 In laboratory and industrial operations, hand or mechanical application of adhesives can be duplicated for cost savings using this practice.
SCOPE
1.1 This practice provides a procedure for the estimation of the quantity of liquid adhesive applied in a spreading or coating operation.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are 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.
