5.1 In some situations, penetration through asphalt-based roofing or waterproofing materials by fasteners is a required part of the material installation process or occurs during installation of other system components. When fasteners penetrate the material as a purposeful and planned part of the construction process, it is reasonable to expect that materials designed to limit migration of liquid water at the interface between the penetrating fastener and the material will do so. This qualitative test method provides a means to evaluate the ability of a material to limit water migration at fastener penetrations when tested under defined conditions.1.1 This qualitative test method determines the capability of asphalt-based roofing or waterproofing material to seal around a fastener that penetrates the material and prevent transmission of liquid water through the material at the penetration under defined conditions.1.2 This test method is provided for adoption by ASTM or other consensus-based roofing and waterproofing product specifications as a standardized means to evaluate capability to seal around a fastener. Performance of this test method after subjecting the product to conditioning intended to simulate environmental stresses and strains is not prohibited.1.3 The text of this test method references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

The values given in parentheses after SI units are provided for information only and are not considered standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 6.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 The resistance of a species of wood or a wood-based product to withdrawal of nails, staples, or screws is a measure of its ability to hold or be held to an adjoining object by means of such fasteners. Factors that affect this withdrawal resistance include the physical and mechanical properties of the wood; the size, shape, and surface condition of the fasteners; the speed of withdrawal; physical changes to wood or fasteners between time of driving and time of withdrawal; orientation of the fastener relative to the fiber axis; and the occurrence and nature of pre-bored lead holes.5.2 By using consistent sizes and types of nails, staples, and screws, withdrawal resistance of a wood species or wood product can be determined, and such values for two or more wood species or wood products can be compared. Similarly, comparative performances of different sizes or types of nails, staples, or screws can be determined by using a standard procedure with a particular wood or wood-based product, which eliminates the wood or the wood-based product as a variable. Since differences in test methods can have considerable influence on results, it is important that a standard procedure be specified and adhered to if test values are to be related to other test results.1.1 These test methods provide a basic procedure for evaluating the withdrawal and lateral resistance of fasteners installed in wood and wood-based materials. Spikes are included as nails in this standard.1.2 The tests also provide a basis for determining comparable performance of different types and sizes of fasteners installed in wood and wood-based materials.1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This specification covers the basic requirements and associated test methods for water-based corrosion protective zinc/aluminum dispersion inorganic basecoats, and optional sealers and topcoats for fasteners. The basecoat can contain chrome (C) or be non-chrome (NC). These coatings are applied to ferrous parts by conventional dip-spin, dip-drain, or spray methods, which can be handled through a cleaning, coating, and baking operation, and which are not adversely affected by baking temperatures up to 330 °C. The coatings are classified into six grades (Grades 1 to 6) according to the required minimum basecoat thickness, and when tested, shall conform accordingly to appearance, adhesion, corrosion resistance, blister, thread fit, and hydrogen embrittlement requirements. The coating process does not induce the possibility of internal hydrogen embrittlement provided that the fasteners have not been cleaned or pre-treated with an acid or phosphate. Alkaline cleaning or vapor degreasing is required along with shot blasting to remove rust or scale. In this specification, units are presented in the metric scale.1.1 This specification covers the basic requirements for water-based zinc/aluminum dispersion inorganic basecoats and optional sealers and topcoats for fasteners.
