GB/T 13477.7-2002 "Test Methods for Building Sealants - Part 7: Determination of Low-Temperature Flexibility" specifies the test method for determining the low-temperature flexibility of building sealants. This method involves bending a standard specimen at a specified low temperature and observing whether cracks occur or if the specimen detaches from the substrate, in order to evaluate the flexibility and deformation capability of the sealant under low-temperature conditions.
