ASTM D714-2017 “Determination of Foaming Degree of Color Paint”

Meaning and Purpose
3.1 A phenomenon peculiar to painted surfaces is the formation of blisters relative to certain system weaknesses. This test method provides standard procedures for describing the size and density of blisters so that severity can be compared.

ASTM D714-2017 “Determination of Foaming Degree of Color Paint”

Scope of
1.1 This test method uses photographic reference standards to assess the extent of foaming that may occur when a paint system is subjected to conditions that can cause foaming. Although primarily used on metal and other non-porous surfaces, the test method can be used to assess blisters on porous surfaces, such as wood, if the size of the blister falls within the range of these reference standards. When the reference standard is used as a performance specification, the permissible degree of foaming of the paint system shall be agreed upon by the buyer and the seller.

1.2 This standard is not intended to address all safety issues, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.

1.3 This international Standard has been developed in accordance with the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the Committee on Technical Barriers to Trade of the World Trade Organization.
