This test method covers the procedure for determining the crazing effect caused by a liquid or semi-liquid on transparent three types of acrylic plastic materials under bending stress. Cast acrylic materials from Types A and B should be annealed according to specifications while the stretched acrylic materials of Type C should not be annealed. All test specimens should be machined from polished acrylic plastic sheets and should have smooth machined surfaces.
