范围
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, 比如木头, 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.
