11.4 Tests and qualifications
11.4.1 Raw material and material reception
All materials used undergo receiving control
by the quality management department. The
materials used are qualified, corresponding
to requirements by material tests according
to ASME and DIN EN 10204.
11.4.2 Monitoring of manufacture
Manufacture is monitored via accompanying
quality control according to the QM manual.
In particular, for nuclear applications the
quality-assuring requirements according to
ASME III NF and KTA are fulfilled.
11.4.3 Final inspection
Before shipment, constant and spring hangers
as well as shock absorbers undergo a function
test on test benches by quality management
personnel. The tests are carried out
using computer-assisted equipment. The
values measured can be recorded by means
of a diagram. In addition, for constant and
spring hangers the digital values can be
printed out over the whole travel range.
The specific test benches employed undergo
regular inspections by an independent supervisory
body.
11.4.4 Documentation on shipment
If so ordered, the materials used are documented
by certification from material tests according
to ASME and DIN EN 10204. In addition,
the results of the function tests can be
confirmed by issuing an acceptance test
certificate, also from a supervisory body if
desired.
Stress reports according to particular specifications
and quality-assuring documents can
be agreed between customer, manufacturer
and supervisory body.
11.5 Suitability test according to KTA 3205.3
and type test according to VGB R 510 L
For the use of series-made standard supports
in conventional power plants, a type test by a
supervisory body (according to § 14 of the
appliance safety law GSG) is foreseen in the
VGB code R 510 L.
For use in nuclear installations a corresponding
suitability test, according to directive 35
of the TÜV’s nuclear technology supervisory
body at the Vd TÜV, is prescribed by nuclear
code KTA 3205.3.
The test program prescribed comprises in
essence the following components:
➜ inspection of the quality management
program
➜ inspection of material used
➜ inspection of the design documentation
➜ inspection of design report summaries
➜ experimental function tests
➜ experimental overload tests
➜ experimental testing of continuous
load capacity
For the broad range of LISEGA products, type
and suitability tests have been conducted
by the German TÜV and VGB and the corresponding
permits granted. Qualifications can
be supplied on request
