28、 requirements specified in 4.2 to 4.11 of this Part 2-2. 4.2 Frame design The frame of the tools shall be of the open throat design. 4.3 Outline dimensions and mass Tools shall comply with following dimensions and mass, which are maxima unless otherwise stated: a) total length of crimping tool: 260
29、mm; b) handle span when crimping tool is closed and no load applied: 50 mm 10 mm; c) handle span when tool is fully open: 180 mm; d) mass of tool: 0,85 kg. NOTE The nominal measurements in b) and c) of 50 mm and 180 mm shall be made between a point on the outside of the shorter handle 25 mm to 35 mm
30、 from its end, and the nearest point on the outside of the longer handle, (points P1 and P2 in Figure 1). 4.4 Clearance In order to allow crimping close to the body of large bodied connectors, the tool shall provide clearance in relation to the dies as follows, and as illustrated in Figure 1: a 20 m
31、m square centred on the large die cavity shall be able to approach within 0,4 mm max of the die face; a 40 mm diameter centred on the large die cavity shall be able to approach within 2 mm of the die face. 4.5 Locator The provision of a locator is permitted as a means of locating the centre contact
32、of an RF connector during the crimping operation. BS EN 50109-2-2:1995 EN 50109-2-2:1995 (E)4 BSI 03-2000 4.6 Operating force (full closure mechanism) The operating force for the full closure mechanism shall be tested as specified in 6.6 of Part 1. The dies shall be closed and a force shall be appli
33、ed to the handles at a point 30 mm to 35 mm from their ends. The force required to operate the release mechanism shall be not less than 20 N. 4.7 Operating force (crimping cycle) The operating force for the crimping cycle shall be tested as specified in 6.7 o f P a r t 1. The largest appropriate tes
34、t piece selected from Table 2 shall be used and shall be crimped at the end of the test piece sleeve. The compression force required to perform a crimping cycle, applied to the handles between points P1 and P2 (see 4.3 and Figure 1) shall not be greater than 425 N. If the test piece is to be gauged
35、subsequently, the crimping cycle shall be taken only to the point where the full closure mechanism allows release. 4.8 Overload force The crimping tool shall be designed such that it will pass the overload force test (6.8 of Part 1 of this Standard) when a force of 700 N is applied to the handles be
36、tween points P1 and P2 (see 4.3 and Figure 1). 4.9 Crimping dies The crimping dies shall always be supplied in pairs, and shall be replaceable by hand. They shall have hexagonal die cavities and outline dimensions in accordance with Table 1 and Figure 2. 4.10 Die alignment With the dies closed but e
37、mpty, misalignment of the dies shall not exceed 0,25 mm in any axis, and the A/F dimensions of Table 1 shall be maintained. Die alignment on closure may be achieved by the tool frame, or the dies themselves may incorporate alignment features. 4.11 Dynamic test Tool performance shall be assessed usin
38、g the procedure of 6.4. This provides a dynamic test comparable to normal operation. 5 Classification and designation 5.1 Tool and die style references 5.1.1 Tool style reference The tool shall be designated by an individual style reference which shall be EN 50109-2-2/T, where EN 50109 is the number
39、 of this European Standard, 2-2 the number of this Part, and the letter T denotes “tool”. 5.1.2 Die style references Dies shall be designated by individual style references which shall consist of three elements as follows: a) the number of this European Standard followed by a hyphen, i.e. EN 50109-;
40、 b) the number of this Part followed by a solidus, i.e. 2-2/; c) the die size code which consists of two letters, the first being the die size for the centre contact and the second being the die size for the outer ferrule (crimp sleeve), e.g. VC. EXAMPLE: Die style reference EN 50109-2-2/VC denotes
41、crimping dies having two hexagon cavities 1,46 mm and 4,52 mm across flats respectively (see Table 1). 5.2 Marking The tools shall be marked with the tool style reference (see 5.1) in accordance with 5.2 of Part 1. In addition the crimping dies shall each be marked with the size code, i.e. the third
42、 element of the die style reference in accordance with 5.1.2 and Table 1. NOTE The crimping dies may also have a distinctive mark identifying paired sets. Where die sets are not reversible the upper and lower dies shall be marked with the letters U and L, respectively (see Figure 2). 6 Test and acce
43、ptance requirements 6.1 General The requirements of clauses 6 and 7 of Part 1 apply using the values specified in clause 4 of this Part 2-2. 6.2 Mechanical endurance The mechanical endurance shall be tested as specified in 6.9 of Part 1. The crimping tool shall be tested without a test piece in the
44、dies and shall be subjected to 10 000 cycles of operation conducted at a rate of 5 to 10 cycles per minute. An appropriate closing force shall be applied to the handles between points P1 and P2 to ensure operation of the full closure release mechanism throughout the test. On the completion of each 1
45、 000 cycles, the dynamic test procedure of 6.4 of this Part shall be applied using six test pieces. No adjustment, repairs, cleaning or lubrication is permitted. 6.3 GO and NOT GO gauges The use of cylindrical GO and NOT GO gauges for checking die cavity sizes is recommended as a routine method of t
46、est.
