The assumption is that the following dimensions have the necessary and sufficient accuracy: a) component tolerance; c) printed board fabrication tolerance; d) placement tolerance. NOTE Further information on the effect of the above dimensional tolerance on the land pattern can be found in Annex A of IEC 61188-6-1:2021. There are two classes of land pattern relating to the assembly limitations of components and the intended soldering process: • land pattern for wave soldering – For low density product applications, land patterns are designed to accommodate several types of wave soldering applicable to surface mounted components. • land pattern for reflow...

5 Quality assessment procedure 5.1 General Clause 1 0 of IEC 61 1 69-1 :201 3 applies to this sectional specification, except as follows: Subclauses 5.2 to 5.4 provide rating, performance and test conditions to be considered when writing a detail specification. They also provide an appropriate schedule of tests with minimum levels of conformance inspection sampling. 5.2 Rating and characteristics (see Clause 5 of IEC 61 169-1 : 201 3) The values indicated below are required for SMPM series RF coaxial connectors unless otherwise stated and are given for the writer of the detail specification. They are applicable for...

1 Scope This part of IEC 61169, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for RF coaxial connectors with inner diameter of outer conductor 4,13 mm (0,163 in) with threaded coupling with a characteristic impedance of 50 Ω (type SMA). This document specifies mating face dimensions for high performance connectors – grade 1, dimensional details of standard test connectors – grade 0, gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to series SMA RF connectors. This document indicates recommended performance characteristics to be considered...

5 Tests 5.1 Test conditions All type tests shall be carried out on the same new and completely assembled WELDING CURRENT RETURN CLAMP . All type tests shall be carried out at an ambient air temperature between 1 0 °C and 40 °C. 5.2 Measuring instruments As specified in 5.2 of IEC 60974-1 :201 7. 5.3 Test sequence The type tests given below shall be carried out in the following sequence: a) general visual inspection; b) temperature rise, see 8.1 ; c) RETAINING MEANS , see 9.1 ; d) drop withstand, see 9.4; e) voltage drop, see Clause 7; f)...

8 Protection against electric shock Protection against direct contact 8.1 An ELECTRODE HOLDER without an electrode, fitted with a welding supply cable of minimum cross- sectional area as specified by the manufacturer, shall be protected against unintentional contact with live parts. In the case of CATEGORY A ELECTRODE HOLDERS , this requirement is also valid for the part of the electrode inserted into the ELECTRODE HOLDER . Electrodes having the minimum and maximum diameter as specified by the manufacturer shall be tested. Conformity shall be checked by: a) an access probe according to Table 6 of IEC 60529:1989 in the...

7.3 Limits of temperature rise As specified in 7.3 of IEC 60974-1:2017. Additionally, the temperature of surfaces exposed to combustible gases shall be at least 20 % cooler than the ignition temperature of any combustible gas intended to be used in the GAS CONSOLE . Conformity shall be checked by operating the GAS CONSOLE at the maximum specified ambient temperature and system duty cycle, while monitoring the inside of the gas console with an IR camera for temperatures exceeding the 20 % margin of the ignition temperature of any combustible gas intended to be used in the GAS CONSOLE ....

The numerical values shall be given for the length of the body, the width and height of the body or for cylindrical types, the body diameter, and the length and diameter of the terminations. When necessary, for example when a number of items (inductance values/ voltage ranges) are covered by a detail specification, the dimensions and their associated tolerances shall be placed in a table below the drawing. When the configuration is other than that described above, the detail specification shall state such dimensional information to describe the inductor adequately. When the inductor is not designed for use on printed...

1 Scope This part of IEC 60794 specifies a method of verifying that cable metallic elements are electrically continuous throughout the cable. Electrical continuity is important for bonding and grounding, toning for location, and other related system issues, and may represent a “goodness of manufacture” criterion. Typically, the test is one of continuity and carries no resistance or conductivity requirement. The metallic elements can be tested individually or can be tested as a total group. Since this latter criterion is frequently the case, all elements are measured as a group unless specified otherwise. NOTE It is possible detail specifications allow...
