5.1 Occasions exist where static charges on the vehicle must be dissipated by way of the tires. Electrical resistance inversely measures the tire's ability to dissipate static charge from the vehicle.1.1 This test method covers the measurement of the electrical resistance between the wheel of a mounted and inflated tire-wheel assembly and a flat conducting surface in loaded contact with the tire.1.2 This test method specifies procedures and equipment such that electrical resistance can be accurately determined for tires with values up to 1012 Ω (ohms).1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.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 deals with the standards for unused round timber piles to be used either treated or untreated. This specification, however, does not cover preused piles unless the piles have the quality and design stresses equal to or greater than those prescribed herein. The piles shall be made of sound wood, free of decay, insect attacks, marine borer attack, and Limnoria damage. The piles shall also be cut above the ground swell and have a tapered tip.1.1 This specification covers the physical characteristics of unused round timber piles to be used either treated or untreated.1.2 This specification is not intended for preused piles unless the piles have the quality specified by this specification and design stresses equal to or greater than those derived from Method D2899.1.3 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.

3.1 The methods contained in this standard are intended primarily for referee use, for laboratory measuring, and for certifying size of standard samples used for checking other measuring equipment that may be agreed upon between the supplier and the purchaser.AbstractThese test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) used in electronic devices and lamps. Anvils shall be used in determining the thickness. The flatness and parallelism of the wire shall be checked using a monochromatic light source, a small optical parallel, and a cylindrical master standard wire gage.1.1 These test methods cover procedures for measuring the diameter or thickness of round and flat wire (ribbon) 0.060 in. (1.52 mm) maximum used in electronic devices and lamps.1.2 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.1.3 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.1.4 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.
