4.1 The coating attached to the substrate will elongate when the substrate size is unstable, or bend during the manufacturing of the item or when the item is abused in use. These test methods can be used to assess the ability of the attached coating to resist cracking when stretched. They can be used to assess the flexibility of coatings on flexible substrates. The elongation of the coating can also be tested using test method D2370. The correlation between the elongation rates determined according to the test methods D522/D522M and D2370 is unknown.

1.2 Values expressed in SI units or ink-pound units shall be considered standards, редом. The values specified in each system are not necessarily exactly equal; Стога, to ensure compliance with the standards, each system should be used independently and the values of the two systems should not be combined.

1.3 Овај стандард није намењен решавању свих безбедносних питања, ако их има, повезана са његовом употребом. Одговорност корисника овог стандарда је да успоставе одговарајућу безбедност, здравствене и еколошке праксе и да се утврди применљивост регулаторних ограничења пре употребе.
