It is identical with IEC Publication169-12 “Ra
9、dio-frequency connectors” Part12 “R.F. coaxial connectors with screw coupling, unmatched (Type UHF)” published in1979 by the International Electrotechnical Commission (IEC). This Part is intended to be read in conjunction with BS3041-1 “Specification for general requirements and measuring methods”.
10、Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following.
11、The comma has been used in some places as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. There is no British Standard equivalent for ISO370 which is referred to in clause5 for information purposes only. A related British Stand
12、ard for this ISOstandard is BS2856 “Precise conversion of inch and metric sizes on engineering drawings”. Additional information. For the purposes of this standard clause2 should be read as follows. “2. BS/IEC type designation Connectors conforming to this standard shall be designated by: the refere
13、nce to this standard, BS3041-12169-12 IEC.” Clause6.1.1.2 b) gives the finish of the second steel test pin as0.44m(164in). These values should be understood as the acceptance level for the arithmetic mean deviation (R a ) as specified in BS1134-1. A British Standard does not purport to include all t
14、he necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Cross-references International Standard Corresponding British Standard ISO263:1973 BS1580 Uni
