GB/T 1731-2020 《Determination of flexibility of coating and putty films》 Related products

"GB/T 1731-2020 Method for determination of flexibility of paint film and putty film" is a standard issued by the National Standardization Technical Committee of China, which replaces the relevant content of GB/T 1731-1993 and GB/T 1748-1979. This standard specifies the method for measuring the flexibility of paint film and putty film by using a flexibility tester. The flexibility of paint film and putty film is evaluated by measuring the minimum shaft rod diameter that does not cause damage, including instrument and material requirements, sample handling and painting, test procedures and methods for expressing results. This standard is suitable for applications in the Coating industry where the flexibility of paint film and putty film is accurately assessed. This standard is proposed by the China Petroleum and Chemical Industry Federation and jointly drafted by a number of units in the field of Coating and chemical industry, aiming to improve the scientific and standardized level of mass evaluation of Coating products.
