8.1 The conductivity of the water extract of electrical grade pulp results from electrolytic impurities in the pulp potentially present as ionizable acids, bases, salts, or a combination of these. The presence of electrolytic impurities in electrical insulation is undesirable as they tend to lower insulation resistance and have corrosion-producing tendencies under conditions of applied potential. When comparing test data, note that the extract conductivity of pulps, especially those of high purity, changes with time after manufacturing in some instances. This test is useful for routine acceptance testing, the comparison of different pulps, and research work.61.1 These test methods cover the sampling and testing of cellulosic pulps for use in the manufacture of electrical insulating papers and boards or in the direct application of pulp fibers as insulation to electrical conductors.NOTE 1: Consider the significance of any one pulp property test method, as set forth herein, with discretion depending on the product made from the pulp.1.2 Sections on Reagents, Sampling, and Report are integral parts of each of the individual test methods that follow.1.3 Each test method is described as being a measure of either a bulk property of the pulp or a property of a handsheet formed from the pulp.1.3.1 Bulk characteristics determinable by these procedures appear in the following sections:Procedure Sections ASTMMethodReference TAPPIMethodReferenceAqueous Extract Conductivity 8 & 9 D202 . . .Aqueous Extract pH 10 & 11 D202 . . .Aqueous Extractable Acidity-     Alkalinity 12 & 13 D202 . . .Analysis of Ash for Cations by     Atomic Absorption Spectrophotometry 70 – 78 D1193 & D2576 . . .Ash Content 79 – 82 D202 T 413Dirt in Pulp 40 & 41 . . .

This specification covers the standard materials composition, physical properties, structural components, manufacturing methods, and testing requirements for articulating concrete block reventment systems for use in erosion protection to underlying soil materials from flowing water forces. Articulating concrete blocks may be produced at a block plant or onsite using either wet-cast or dry-cast production techniques. Reventment cable and fittings shall be designed in such a manner as to provide adequate strength and durability characteristics to facilitate safe lifting and placing of large mattresses. The materials shall consist of aggregates and cementitious materials which shall be Portland, blended, hydrated lime, or pozzolan cements and shall conform to the physical requirements such as compressive strength, water absorption, density or unit weight, and freeze-thaw durability. The system includes a geotextile filter which shall comply to grab strength, sewn seam strength, tear strength, puncture strength, and elongation requirements. Geotextile-subsoil compatibility assessment shall include functional requirements for permeability, particle retention, and resistance to clogging. Physical property requirements for permittivity, aperture size, percent open area, and UV stability shall be based on site-specific soil characteristics, site conditions, and construction techniques.1.1 The purpose of this standard is to provide specifications for articulating concrete block (ACB) revetment system structural components, material composition and physical properties, manufacturing methods and testing requirements.1.2 Units—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. Reporting or use of units other than inch-pound shall not be regarded as non-conformance with this standard.1.2.1 The gravitational system of inch-pound units is used when dealing with inch-pound units. In the system, the pound (lbf) represents a unit of force (weight), while the units for mass is slugs. The slug unit is not given, unless dynamic (F = ma) calculations are involved.1.2.2 The SI units presented for apparatus are substitutions of the inch-pound units, other similar SI units should be acceptable providing they meet the technical requirements established by the inch-pound apparatus.1.2.3 It is common practice in the engineering/construction profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf). This practice implicitly combines two separate systems of units; the absolute and the gravitational systems. It is scientifically undesirable to combine the use of two separate sets of inch-pound units within a single standard. As stated, this standard includes the gravitational system of inch-pound units and does not use/present the slug unit of mass. However, the use of balances and scales recording pounds of mass (lbm) or recording density in lbm/ft3 shall not be regarded as nonconformance with this standard.1.2.4 The terms density and unit weight are often used interchangeably. Density is mass per unit volume, whereas unit weight is force per unit volume. In this standard, density is given only in SI units. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.1.2.5 Calculations are done using only one set of units; either SI or gravitational inch-pound. Other units are permissible provided appropriate conversion factors are used to maintain consistency of units throughout the calculations, and similar significant digits or resolution, or both are maintained.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.
