ScopeThis recommended practice defines a procedure for the construc
5、tion and testing of a 180 deg peelspecimen for the purpose of determining the bondability of glass to elastomeric material in automotive modularglass. This test method suggests that elastomeric material of less than 172 mpa modulus be used as theencapsulating material. The present practice of encaps
6、ulating automotive glass is described as molded-in-place elastomeric material onto the outer edge of the glass using thermoplastic or thermosetting material thatquickly sets in the mold. The glass is removed from the mold with the cured elastomeric material bonded tothe perimeter of the glass. This
7、encapsulated glass module can now be bonded with a sealant adhesive intothe body opening of a vehicle.2.

Test Specimen4.1 Glass EncapsulationThe samples for testing should be from glass encapsulated using injection moldingequipment and procedures recommended by automoti
11、ve engineers.4.2 Preparation for SpecimenFor ease of test specimen preparation in 3.5, it is recommended that the glassnot be primed where the elastomeric material is to be cut out.4.3 Encapsulation Dimensions and TolerancesThe elastomeric material should be molded onto the glasssuch that the width
12、dimensions shall be at 6.4 mm (0.25 in) with a tolerance of 0.25 mm (0.01 in). Thethickness dimensions shall be at 3.2 mm (0.125 in) with a tolerance of 0.128 mm (0.005 in). The overalllength of the encapsulation shall be at least 203 mm (8 in) and should not have any flaws or nicks that couldresult
13、 in erroneous test results.FIGURE 1ENCAPSULATED TEST SPECIMEN4.4 Test Specimen Conditioning and AgingThe molded glass should be conditioned according to suppliers orautomotive engineers recommendation.4.5 Test Specimen PreparationAt least 102 mm (4 in) should be cut away from the glass as illustrate
