ASTM G198-17

Standard Test Method for Determining the Relative Corrosion Performance of Driven Fasteners in Contact with Treated Wood

SIGNIFICANCE AND USE
5.1 This test method provides controlled environments which are utilized to produce corrosion of metal, metal-coated, or nonmetallic-coated smooth or deformed shank driven fasteners in contact with treated wood exposed to the given test environments. The test method provides information that can be used to evaluate the corrosion resistance of metal, metal-coated, or nonmetallic-coated smooth or deformed shank driven fasteners in contact with different chemical wood treatments.  
5.2 The results shall be used for comparative purposes only and they shall not be correlated to exposure time in natural environments.  
5.3 The reproducibility of results in these types of tests is highly dependent on the type of samples tested and the evaluation criteria selected, as well as the control of the operating variables.
SCOPE
1.1 This test method covers and focuses on the corrosion resistance of metal, metal-coated, and nonmetallic-coated smooth and deformed shank driven fasteners in contact with treated wood in exterior or high moisture exposure applications using comparative tests with control fastener specimens of standardized benchmarks. This test method may be used for preservative-treated wood.  
1.2 This test method describes the apparatus, procedure, and conditions required to maintain test environments for the Cyclic Fog Test and the Steady State Moisture Test.  
1.3 This test method describes the types of test samples, lists exposure periods, and gives guidance on interpretation of results.  
1.4 Until experience is gained comparing laboratory-to-laboratory results with this test method, comparisons of fasteners, coatings, materials, or preservatives shall be made only within the results of the same test.  
1.5 The values stated in SI units are to be regarded as standard. The values in parentheses are for information only.  
1.6 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 and health practices and determine the applicability of regulatory limitations prior to use.  
1.7 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.
