1、Designation: C 1375 00 (Reapproved 2009)Standard Guide forSubstrates Used in Testing Building Seals and Sealants1This standard is issued under the fixed designation C 1375; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year o
2、f last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide describes the recommended standard sub-strates and their recommended surface preparation for use instanda
3、rd tests of building seals and sealants.1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory

Comparison to Other Standards5.1 The ASTM committee with jurisdiction over this stan-dard1is not aware of any comparable standards published byother organizations.6. Glass Substrate6.1 The glass used shall be float glas
7、s, which conforms toSpecification C 1036, Type I, Class 1, q3. This corresponds toa glass that is formed on a float line, is transparent, clear, andintended for architectural fenestration applications.6.2 Float glass has two surfaces, which are not necessarilyidentical in surface chemistry. There is
8、 a tin side, which was incontact with a batch of molten tin, and an air side, which didnot have this intimate contact. These two surfaces may or maynot have the same adhesion properties with a given sealant. Itis best to test both surfaces for control of testing. If only onesurface is to be tested,
9、however, it is preferred to use the airside 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 shortwavelength UV light source of approximately 254 nm. The tinside will
10、 fluoresce and display a hazy white reflectance. The airside will not show this effect under the same UV light.(WarningProtect eyes and skin from exposure to UV lightwhen using a UV light source.)6.4 Surface PreparationThe substrate should be cleanedthoroughly with a solution of 50 % isopropyl alcoh
11、ol (IPA) and50 % deionized or distilled water and wiped with a clean, lintfree, soft cloth or paper towel. Prepared specimens must beused within the same working day. Check surfaces for clean-liness by running distilled or deionized water over the glasssurface held in a vertical position. Cleaned pa
12、rts must passwater-break inspection as indicated by maintenance of acontinuous film of water on the surface for not less than 30 s.Panels failing the water-break inspection should be recleaneduntil the surface can maintain the continuous film of water.7. Aluminum Substrates7.1 The aluminum shall be
13、one of two materials, dependingon the test sample configuration:7.1.1 For tests requiring a sheet, less than 6 mm thick, thesheet shall be made of aluminum alloy 5005-H34.7.1.2 For tests requiring a thicker plate, 6 mm or greater, theplate shall be made of aluminum alloy 6063-T5.1This guide is under
