GB/T 13477.16-2002 Focusing on the determination of compression characteristics of building sealing materials. This standard specifies the technical requirements of test equipment, such as Pressure Tester. Detailed specification of specimen preparation, pressure on the sealing material specimen under specific pressure conditions, and record its compression deformation, rebound and other data. Evaluate the performance of sealing materials under compression with these data, including compressire strength, compression permanent deformation and other indicators. This provides a key test basis for the sealing Reliability of building sealing materials under extrusion in practical applications, and helps to ensure the effectiveness of sealing engineering under pressure environment.
