Ghid standard ASTM D6763-16 pentru testarea petelor de lemn pentru exterior și a substanțelor hidrofuge

abstractizare

This guide covers the selection and use of procedures for testing exterior wood stains. Aceasta include apa – 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.

Etapa 1: Domeniul de aplicare

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, in unele cazuri, the relevant test procedures are listed in 2.1 și 2.2.

Notă 1: Termenul “opaque stainis 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.

Notă 2: Termenul “translucencyis 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.

Notă 3: Termenul “transparentis 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 DiscussionWhen applied to wood of different colours, there is a colour difference between the stained substrates.

1.2 Valorile exprimate în inci în lire vor fi considerate valori standard. Valorile date în paranteze sunt transformări matematice ale unităților SI și sunt doar pentru referință și nu sunt considerate standard.

1.3 This standard may address hazardous materials, operations and equipment. Acest standard nu este destinat să abordeze toate preocupările legate de siguranță, dacă există, asociat cu utilizarea acestuia. Users of this standard are responsible for establishing appropriate safety and health practices and for determining the applicability of regulatory requirements prior to use.
