ARAMID - A lightweight strong heat-resistant aromatic polyamide material used in fiber optic strength members.
ARMATURE WIRE - Stranded annealed copper wire, straight lay, soft loose white cotton braid. It is used for low voltage, high current rotor winding motors and generators. Straight lay permits forming in armature slots and compressibility.
ARMOR - An outer braid of metal or spiral steel tapes, primarily for the purpose of mechanical protection. Generally placed over the outer sheath.
AROMATIC - An organic material composed of benzene in a ring structure.
ARTOS STRIPPER - A machine that will automatically measure to a predetermined length, cut, strip, count, and tie wire in bundles.
ASA - Abbreviation for American Standards Association. Former name of the American National Standards Institute (ANSI). See ANSI.
ASESA - Abbreviation for Armed Services Electro Standards Agency.
ASG - Abbreviation for Aeronautical Standards Group.
ASME - Abbreviation for American Society of Mechanical Engineers.
ASTM - Abbreviation for American Society for Testing Materials. An organization that tests materials and attempts to set standards on various materials for industry.
ATTENUATION - The loss of power or signal in a circuit, generally expressed in decibels (dB) per unit length, usually one thousand (1,000) feet. In optical fiber cables, attenuation is the ratio of input power vs. output power, measured in decibels per unit length, usually dB/km. Abbreviated as attn.
ATTN. - Abbreviation for attenuation. See attenuation.
