ASTM D2064-16 Standard Test Method para sa Printability ng Architectural Coatings

Kahulugan at paggamit

5.1 The ability of the coating to resist printing is important because if the smoothness of the coating is changed through contact with another surface, especially a textured surface, its appearance will be adversely affected. Interior paint systems, especially gloss and semi-gloss on windowsills and other horizontal surfaces, often have objects such as flower POTS placed on them, which may tend to leave a lasting impression. This tendency of paint film “paglilimbag” is a function of coating hardness, pressure, temperatura, kahalumigmigan, and the duration of the object’s contact with the painted surface.

ASTM D2064-16 Standard Test Method para sa Printability ng Architectural Coatings

Hakbang 1: Saklaw

1.1 The test method includes an accelerated procedure for evaluating printability of architectural coatings. It differs from the printed resistance test method D2091 in that the latter relates to finishes under packaging, transportation, and storage conditions, while this test method relates to decorative coatings that experience random field pressure contact.

Tala 1: Printing should not be confused with blocking, which is measured in test method D4946. The former involves the indentation of a surface, while the latter involves the bonding of two surfaces.

1.2 Values in inch-pounds shall be considered standard. Ang mga halaga na ibinigay sa mga panaklong ay para sa sanggunian lamang.

1.3 Ang pamantayang ito ay hindi nilayon upang matugunan ang lahat ng mga alalahanin sa kaligtasan, kung meron man, na nauugnay sa paggamit nito. Responsibilidad ng mga gumagamit ng pamantayang ito na magtatag ng angkop na mga kasanayan sa kaligtasan at kalusugan at upang matukoy ang pagiging angkop ng mga paghihigpit sa regulasyon bago gamitin.
