This guide covers the selection and use of procedures for testing exterior wood stains. Це включає воду – 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.

Крок 1: Область застосування

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 some cases, the relevant test procedures are listed in 2.1 і 2.2.

Примітка 1: Термін “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.

Примітка 2: Термін “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.

Примітка 3: Термін “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 Values in inches to pounds shall be considered as standard values. Значення, наведені в дужках, є математичними перетвореннями одиниць СІ та наведені лише для довідки та не вважаються стандартними.

1.3 This standard may address hazardous materials, operations and equipment. Цей стандарт не призначений для вирішення всіх питань безпеки, якщо хто-небудь, пов'язані з його використанням. Users of this standard are responsible for establishing appropriate safety and health practices and for determining the applicability of regulatory requirements prior to use.
