This guide covers the selection and use of procedures for testing exterior wood stains. وهذا يشمل الماء – 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 الدليل القياسي لاختبار بقع الخشب الخارجي والمواد الطاردة للماء

خطوة 1: نِطَاق

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, في بعض الحالات, the relevant test procedures are listed in 2.1 و 2.2.

ملحوظة 1: على المدى “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.

ملحوظة 2: على المدى “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.

ملحوظة 3: على المدى “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 تعتبر القيم بالبوصات إلى الجنيهات بمثابة قيم قياسية. القيم الواردة بين قوسين هي تحويلات رياضية لوحدات النظام الدولي للوحدات وهي للإشارة فقط ولا تعتبر قياسية.

1.3 This standard may address hazardous materials, العمليات والمعدات. لا يهدف هذا المعيار إلى معالجة جميع المخاوف المتعلقة بالسلامة, لو اي, المرتبطة باستخدامه. Users of this standard are responsible for establishing appropriate safety and health practices and for determining the applicability of regulatory requirements prior to use.
