Other substrates may betested; however, c
16、onsideration needs to be given to maintaining adequate rigidity of the substrates during testing.5.5 SpacerOne piece spacer made from polytetrafluorethylene (PTFE) or a suitable rigid material shall be used to which thetest sealant will not bond.5.6 Substrate Cleaning Materials.5.7 Primer (if needed
17、).6. Test Specimen6.1 Assembly:6.1.1 Prior to assembly, wipe the substrates with a clean, dry, lint-free cloth, then thoroughly clean with a solution appropriatefor the substrate material. Prior to evaporation of the cleaning solution, wipe the substrates dry with a clean, lint-free cloth.NOTE 3The
18、precision and bias statement is based on glass substrates with a recommended cleaning solution of a 50 to 50 ratio isopropanol and water.6.1.2 Apply recommended primer, if required. Then, construct the test specimen assemblies by forming a sealant cavity 12.7by 12.7 by 50.8 mm (0.50 by 0.50 by 2.0 i
19、n.) between two substrate panels (see Fig. 1) with the aid of appropriate spacers.6.2 Preparation of Test Assemblies:6.2.1 Prepare a set of five test specimen assemblies for each sealant and substrate combination being tested (see Fig. 1).NOTE 4Five test specimen assemblies should be prepared for ea

If an analogchart recording device is being used, the chart speed should be a minimum of 127 mm (5.0 in.) per minute (508 mm (20.0 in.)per minute is preferred) to allow for a more accurate reading of force at specific elongations.8.1.2 Measure a
