ASTM D7733-12(2016)

Standard Specification for Acrylic Dispersion Ground

ABSTRACT
This specification specifies test methods which measure minimum qualities for acrylic dispersion grounds. It indicates the conditions that affect the quality of acrylic dispersion grounds that are not covered in the specification, such as wet ground properties, dry properties, and storage. This specification also mentions several methods that are used to test some of these conditions, including adhesion, oil hold out, and flexibility.
SCOPE
1.1 This standard specifies test methods which measure minimum qualities for acrylic dispersion grounds.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

producers, distributors and users.
4.2 It is not intended that all grounds meeting this requirement be identical nor have uniform excellence in all respects. Variation
in manufacture not covered in this specification may cause some artists to prefer one brand to another, either of which may be

5. Labeling Requirements
5.1 Acrylic dispersion products conforming to this standard will include acrylic, polymer, dispersion polymer, or acrylic
dispersion in their description to differentiate them from traditional gessoes.
