5、Commission (CITEL). ATIS is accredited by the American National Standards Institute (ANSI). For more information, please visit . AMERICAN NATIONAL STANDARD Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other criteria for appro

6、val have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessarily

7、unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made towards their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the standards or n

36、nned (lead free), soft or annealed copper wire meeting the electrical and mechanical requirements of ASTM B3 or ASTM B 33. ATIS-0600028.2011 8 5.2 Conductor Stranding Type 5 cables shall be constructed of conductors having concentric (reverse concentric, unilay, or combination) lay members per ASTM

37、B8, Class B. Type 6 cables shall be constructed of concentric (reverse concentric, unilay, or combination) rope-lay stranded copper conductors having bunch stranded members per ASTM B172, Class I. 5.3 Conductor Size & Dimensions The conductor diameters shall be within -2%+5% of the nominal value and

38、 shall not be less than the minimum values in Tables 4 and 5. The DC resistance shall not exceed the maximum value for tinned copper in Tables 4 and 5. The bare wire conductor diameter shall be determined by: 1. Removing approximately one inch of insulation from a cable sample at least 6 inches from

39、 the end so that there is at least 6 inches of cable insulation on each side of the exposed conductor where the insulation has been removed. 2. Take four individual diameter measurements (with a calibrated digital machinists micrometer-caliper) made 45 degrees apart around the exposed bare wire cond

40、uctor of the cable sample. 3. Average the four measurements to determine the bare wire conductor diameter. Cross-sectional Area shall be determined using the weight method defined in UL 1581, section 210. The number of strands and diameter of each strand are provided for reference. The more importan

41、t parameters are: finished stranded conductor diameter, cross sectional area, and electrical resistance.
