NOTE: The nominal measurements in b) and c) of 50 mm and 180 mm shail be made between a point on the outside of the shorter Me 25 mm to 35 mm from its end, and the neorest point on
24、 the outside of the longer handle oints P1 and Pz in figun 1). 4.4 Clearance in order to aiiow 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 2: - a 20 mm square centred on the large die cavity
25、shall be able to approach within 0,4 mm of the die face; - a 40 mm diameter centred on the large die cavity shail 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 of an RF connector during the crimping oper

The dies shall be closed and a force shall be applied to the handles a
27、t 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 testcd as specified in 6.7 of part 1. The appropriate test piece selected from table 2 s
28、hall 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 subsequently, the crimping cycl
29、e shall be taken only to the point where the full closure mechanism allows re lea se 4.8 Overload force The crimping tool shall be designed such that it will pass the overload force test (6.8 of Part 1) when a force of 700 N is applied to the handles between points P1 and P2 (see 4.3 and figure 1).
30、4.9 Crimping die cavities The crimping dies shall have die cavities in accordance with table 1 and figuq 2. 4.10 Die alignment With the dies closed but empty, misalignment of the dies SU not exceed 0,25 mm in any axis, and the A/F dimensions of table 1 shall be maintained. 4.11 Dynamictest Tool perf
31、ormance shall be assessed using the procedure of 6.4. This provides a dynamic test comparable to normal operation.

EXAMPLE: Tool style reference EN 50109-2-1/WD denotes crimping dies having two hexagon cavities, 1,69 mm and 5,41 mm across flats respectively (see table 1). 5.2 Marking 5.2.1 The tools shall be marked With
34、 the tool style reference (see 5. i) in accordance with the requirements of 5.1 of Part 1. 5.2.2 In addition the crimping dies or the tool frame adjacent to the dies shall be marked with the size code letters, i.e. the third element of the tool style reference in accordance with 5.lc and table 1. 6
35、Test and acceptance requirements 6.1 Generp1 The requirements of clauses 6 and 7 of Part 1 apply using the values specified in clause 4 of this Part 2-1. 6.2 Mechaiuca leadurance The mechanical endurance shall be tested as specified in 6.9 of Par - surface texture shall be measured in accordance wit
