TCVN 10671-2015 《Paints and varnishes - Cupping test》 Related products

TCVN 10671-2015 is a Vietnamese national standard, equivalent to the international standard ISO 1520:2006, which specifies the cupping test method for Paints and varnish. The standard aims to evaluate the cracking resistance and disbonding resistance of coatings under standard conditions, especially when the coating is subjected to gradually applied pressure. The test observes whether the coating appears crazing or disbonding from the metal substrate by applying pressure to the coating using a spherical punch. The standard is applicable to single-layer and multi-layer coating systems and can provide important reference data for the performance of coatings, ensuring the Reliability and durability of coatings in practical applications. By implementing this standard, the mass of coatings can be effectively monitored and the healthy development of the coatings industry can be promoted.
