GOST 12820 Blind
Some of the materials listed in Table 1A undergo a decrease in toughness when used at low temperatures, to the extent that Codes referencing the Standard may require impact tests for application even at temperatures higher than −7°C (+20°F). It is the responsibility of the user to ensure that such testing is performed.
