1. Scope
1.1 This guide describes the recommended standard sub- strates and their recommended surface preparation for use in standard tests of building seals and sealants. 1.2 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 appro- priate safety, health, and environmental practices and deter- mine the applicability of regulatory limitations prior to use. 1.3 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
5. Comparison to Other Standards
5.1 The ASTM committee with jurisdiction over this stan- dard is not aware of any comparable standards published by other organizations.
6. Glass Substrate
6.1 The glass used shall be float glass, which conforms to Specification C1036, Type I, Class 1, q3. This corresponds to a glass that is formed on a float line, is transparent, clear, and intended for architectural fenestration applications. 6.2 Float glass has two surfaces, which are not necessarily identical in surface chemistry. There is a tin side, which was in contact with a batch of molten tin, and an air side, which did not have this intimate contact. These two surfaces may or may not have the same adhesion properties with a given sealant. It is best to test both surfaces for control of testing. If only one surface is to be tested, however, it is preferred to use the air side as this is likely a more consistent surface. 6.3 Determination of Air Side Versus Tin Side: 6.3.1 Clean the glass as described in 6.4. 6.3.2 Expose the substrate to the radiation from a short wavelength UV light source of approximately 254 nm. The tin side will fluoresce and display a hazy white reflectance. The air side will not show this effect under the same UV light. (Warning—Protect eyes and skin from exposure to UV light when using a UV light source.) 6.4 Surface Preparation—The substrate should be cleaned thoroughly with a solution of 50 % isopropyl alcohol (IPA) and 50 % deionized or distilled water and wiped with a clean, lint free, soft cloth or paper towel. Prepared specimens must be used within the same working day. Check surfaces for clean- liness by running distilled or deionized water over the glass surface held in a vertical position. Cleaned parts must pass water- break inspection as indicated by maintenance of a continuous film of water on the surface for not less than 30 s. Panels failing the water-break inspection should be recleaned until the surface can maintain the continuous film of water.
7. Aluminum Substrates
7.1 The aluminum shall be one of two materials, depending on the test sample configuration: 7.1.1 For tests requiring a sheet, less than 6 mm thick, the sheet shall be made of aluminum alloy 5005-H34.7.1.2 For tests requiring a thicker plate, 6 mm or greater, the plate shall be made of aluminum alloy 6063-T5. 7.2 The aluminum for either a sheet or plate shall have a clear, Class II anodized finish conforming to AA-M12C22A31 (refer to Aluminum Association Circular 45). The anodized surface shall be sealed using a hot water process. 7.3 Surface Preparation—The substrate should be cleaned thoroughly with a solution of 50 % isopropyl alcohol (IPA) and 50 % dionized or distilled water and wiped with a clean, soft, lint-free cloth or paper towel. At the request of the manufacturer, cleaning with methyl ethyl ketone or similar solvent may precede the isopropyl wash. Panels must pass the water-break free test described in 6.4. Prepared substrates must be used within the same working day.
