This guide covers the selection and use of procedures for testing exterior wood stains. To zahrnuje vodu – and solvent-based translucent and opaque stains. The different conditions affecting the coating are introduced in detail. A balance of performance needs to be considered when determining requirements and selecting tests. Different test methods for determining the properties of liquid coatings are listed and discussed. Different methods for determining coating application and film formation are proposed and discussed in detail. Different test methods for determining the appearance of dry film are given. Different test methods for determining dry coating properties are described in detail. Different test methods and practices for chemical analysis of external wood are described in detail. While many suggested test methods attempt to simulate the coating and the conditions under which the coating is used, it is not possible to accurately replicate all possible conditions. It is recommended to use the test material under field conditions, including appropriate controls, for final assessment of its suitability.

ASTM D6763-16 Standardní příručka pro testování venkovních mořidel na dřevo a vodoodpudivých látek

Krok 1: Rozsah

1.1 This guide covers the selection and use of procedures for testing exterior wood stains and water repellents. This includes water-based and solvent-based translucent and opaque stains and clear water repellents. The attributes that can be checked or, v některých případech, the relevant test procedures are listed in 2.1 a 2.2.

Poznámka 1: The term “opaque stain” is defined as a tinted composition applied to a wood surface to produce an even finish that obscures the grain and color of the wood rather than the surface grain; Also known as solid color or solid skin.

Poznámka 2: The term “translucency” is defined as a tinted composition used on a wood surface to produce an even finish that does not completely obscure the grain or grain of the wood.

Poznámka 3: The term “transparent” is defined as a transparent composition used on a wood surface to produce an even finish that does not obscure the grain or grain of the wood.

1.1.1 Discussion – When applied to wood of different colours, there is a colour difference between the stained substrates.

1.2 Hodnoty v palcích až librách se považují za standardní hodnoty. Hodnoty uvedené v závorkách jsou matematické transformace jednotek SI a jsou pouze orientační a nejsou považovány za standardní.

1.3 Tato norma se může zabývat nebezpečnými materiály, operace a zařízení. Tato norma není určena k řešení všech bezpečnostních problémů, jestli nějaký, spojené s jeho užíváním. Users of this standard are responsible for establishing appropriate safety and health practices and for determining the applicability of regulatory requirements prior to use.
