3 Definitions
3.1
end fittings for swaging onto control cables
defined by standards EN 2357. EN 2358. EN 2359, EN 2360. EN 2361 and EN 2362
3.2
cable turnbarrel components
defined by standards EN 2353. EN 2354. EN 2355. EN 2356. EN 2363 and EN 2609
3.3
cable turnbarrel assembly
deflned as the assembly of the following components:
— turnbarrel:
— locking dip;
— threaded junction parts (2) which can be fork.ends. eye.ends or stud.ends swaged on type. these various assemblies arc not the subject of product standards
3.4
surface discontinuities
crack
rupture in the material which may extend in all directions and which may be intercrystalline or transcryscalline in character
score
open surface defect which is the result from a metallic tearing lap
surface defect caused by folding over metal particles or sharp edges which are then rolled or forged into the surface
seam
unwelded lap which appears as an open defect in the material
3.5
production batch
a production batch comprises parts having the same identity block, manufactured in the same production sequence, produced from the same material hatch and having undergone together the heat treatments
3.6
delivery hat(h
two cases may arise:
Homogeneous batch made up of one and the same production batch:
The sampling plan is applicable to the whole of the delivery batch.
— Heterogenous batch made up of different production batches:
The sampling plan is applicable to each production hatch.
4 Required characteristics, inspection and test methods
See Table 1.
5 Quality assurance
5.1 Manufacturer approval
See EN 2000.
5.2 Qualification
5.2.1 End-fittings or turnbarrel components
According to Table 5 and Table 6.
The order of the inspections or tests is left to the initiative of the qualification authority.
5.2.2 Turnbarrel assembly
Even though they are not the subject of product standards, the turnbarrel assemblies shall be submitted to the tests given in Table 7 and Table 8 in order to qualify their individual components on the basis of their behaviour in service.
The order of the inspection or tests is left to the initiative of the qualification authority.EN 2569-1991 pdf download.
