How should different levels of reinforcement be addressed in the testing of glazed products?
The approach is to determine the largest level of reinforcement, which typically corresponds to the highest pressure for the system. Arrange the units in decreasing level of reinforcement and projected/applicable design pressure. If non-impact resistant, the following applies: Test three units of the highest level of reinforcement to the highest design pressure for the system as required in TAS202. These units are to undergo all of the requirements of TAS202. Then test one additional sample for each decreased level of reinforcement and to the corresponding determined design pressure. Each of these additional specimens is to be tested to the structural requirements of TAS202, and depending if other parts of the system are decreased (such as sill heights or glass thickness) the water test will also apply. If impact resistant, the following applies: Test one unit of the highest level of reinforcement to the highest design pressure for the system as outlined in TAS202. This unit is to unde
