This specification lists code word names for bare overhead electrical conductors that are recognized in North America. Code word names are used to describe various conductor constructions used in North America, Europe and elsewhere in the world. The code word name construction can be modified with the use of suffix modifiers that identify additional construction variations. For example, the type of steel core material used in an ACSR (aluminum conductors, steel reinforced) type of conductor may be modified with the letter designation "/GA3" denoting the strength and type of coating for the steel core material. The code word names are grouped into tables of like constructions. The tables provide the applicable ASTM standard for which the conductor construction may be built to. They include code word names that are referenced in Canadian Standards Association (CSA) and European Committee for Electrotechnical Standardization (CENELEC) standards.1.1 This specification lists code word names for bare overhead electrical conductors that are recognized in North America. A procedure has been outlined for adding additional code word names to this standard. Code word names have been in existence for many years describing various conductor constructions used in North America, Europe and elsewhere in the world. Their origin is not clearly understood. The historical basis of this standard originates from code word names developed years ago by member utility companies that participated in the US Aluminum Association, Technical Committee.1.2 The code word names are grouped into tables of like constructions. The code word name construction can be modified with the use of suffix modifiers that identify additional construction variations. For example the type of steel core material used in an ACSR type of conductor may be modified with the letter designation “/GA3” denoting the strength and type of coating for the steel core material.1.3 The tables provide the applicable ASTM standard for which the conductor construction may be built to. For conductors that are unique to use in Canada, the applicable CSA International standard is referenced.1.4 The tables include code word names that are referenced in Canadian CSA and European CENELEC standards. The information is believed to be correct however the user of this document is encouraged to consult the applicable CSA or CENELEC standard for confirmation.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.

5.1 To model the mechanical characteristics of overhead electrical conductor, stress-strain characteristics must be determined. The most accurate method for determination of these characteristics is a laboratory stress-strain test. These mechanical characteristics can then be used to determine the strain response of a conductor to mechanical loads, and thus predict the sag of the conductor. This can then be used to determine the required installation parameters to provide safe clearance and tension for the conductor usage.1.1 This test method covers the measurement of the elastic and short-term creep characteristics of conductors for overhead power lines.1.2 Stress-strain data from tests performed in accordance with IEC 61089 are compliant with this standard.1.3 Stress-strain data from prior Aluminum Association testing procedures are compliant with this 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 non-conformance 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.

4.1 A major concern for administrative officials is the security of barriers used in detention/correctional facilities. These test methods are designed to aid in identifying levels of physical security for horizontal fixed barriers, which serve to enclose or separate secure areas. This does not apply to the passage of contraband or vandalism.4.2 These test methods are not intended to provide a measure of resistance for a ceiling subjected to attack by corrosive agents, by high-powered rifles, explosives, sawing, or other such methods not typically available to inmates. These test methods are intended to evaluate the resistance of a ceiling to violent attacks by sustained manpower using battering devices, such as benches, barbells, bunks, or tables; and by an upward static force such that could be applied by an inmate pushing against the ceiling with his hands, feet, or back (that is, squat position on a top bunk in a cell). Attacks from outside the facility and fire resistance ratings are not addressed in this standard.4.3 The primary purpose or result of these test methods is to approximate the levels of abuse to which horizontal fixed barriers could possibly be subjected in the field. The desired result of its use is to help provide assurance of protection to the public, to facility personnel, and to the inmates themselves.4.4 It is recommended that detention/correctional facility administration provide adequate training, supervision, and preventive maintenance programs to enable horizontal fixed barriers to function as intended throughout the expected service life.1.1 These test methods cover requirements for simulated service tests and testing equipment for determining the performance characteristics of horizontal fixed barriers designed to incarcerate inmates in detention and correctional institutions. The testing equipment provides for the setup and testing of sample barriers and installation systems.1.2 It is the intent of these test methods to help ensure that detention security horizontal fixed barriers perform at or above minimum acceptable levels for control of passage to unauthorized or secure areas, to confine inmates, and to delay and frustrate escape attempts. Provide security grilles, access doors, light fixtures, and similar assemblies compatible with these levels of performance, with test apparatus adjustments as required to suit the particular product.1.3 These test methods apply to horizontal fixed barriers enclosing or separating secure areas of detention/correctional facilities.1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversion to SI units that 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.

This specification covers non-specular surface finishes on overhead aluminum electrical conductors to establish a uniformity of conductor finish that is acceptable to the user. Such a specification will furnish a basis for consistent manufacturing process control. Overhead aluminum electrical conductors, when installed, tend to have a "reflective" or "specular" surface that can make a transmission line more noticeable in appearance against the background landscape. A factory treatment process of the outer surface of the aluminum wires can turn the surface finish into a dull, non-reflective, or "de-glared" matte grey finish that allows the conductor to become less visible when observed from a distance and enables the transmission line to blend in with the skyline or landscape background. This specification addresses ordering information, equipment, test procedure, requirements, and retest.1.1 This specification covers non-specular surface finishes on overhead aluminum electrical conductors. Overhead aluminum electrical conductors, when installed, typically have a shiny surface appearance. This “reflective” or “specular” surface can make a transmission line more noticeable in appearance against the background landscape. A factory treatment process of the outer surface of the aluminum wires can render the surface finish into a dull, non-reflective, matte grey finish. This non-reflective or “de-glared” surface finish allows the conductor to become less visible when observed from a distance and enables the transmission line to blend in with the skyline or landscape background.21.2 This specification is intended, by means of diffuse reflectance measurement, to establish a uniformity of conductor finish which is acceptable to the user. Such a specification will furnish a basis for consistent manufacturing process control.1.3 The values stated in inch-pound units are to be regarded as standard.
