Comments to LISI
EN3740 ; ASD-Cert 392-1-7
1. EN 9100 is expired since 06.2019.
Qualification performed in November 2017 (QTP and QTR issued in September 2018 )
Are there any explanation between “Tests performed in November 2017 and report issued in September 2018.
2. QTR 010-18 EN 3740-080; page 10; Tensile Test Results
The requirements for the 080 size in line with ISO is 46KN. The report showed 20kN. There is an inconsistency to the Double shear test results which correspond to the-080 size (66KN)
3. Tension Fatigue Test results para 5.4.3 (for all sizes)
There are no load values listed in the report. Only number of cycles are listed without any load values.
Test were performed in May 2016. Can this be accepted regarding the time between tests and report?
4. QTR 010-18 EN 3740-100; page 12; Tensile Test Results
The requirements for the 080 size in line with ISO is 72KN. The report showed 46kN. There is an inconsistency to the Double shear test results which correspond to the-100 size (104KN)
5. Fatigue Test Result for -100, page 13
Explanation why no tested up to 130 000 cycles for all test samples. Are there failure occurred, or did the test facility stopped?
6. QTR 010-18; EN 3740-150 Tensile Test Results page 14
What is the reason to use MPa instead on KN. The Technical Specification requires a load. Reason to provide values in MPa? Are these calculated values?
Explanation is necessary where are the values from. We know that this is a drilled shaft.
7. QTR 010-18; EN 3740-170 Tensile Test Results page 15
What is the reason to use MPa instead on KN. The Technical Specification requires a load. Reason to provide values in MPa? Are these calculated values?
Explanation is necessary where are the values from. We know that this is a drilled shaft.

Can you explain why the “Material MO Date Valid COC in Annex 4” have a later date than all the other dates of the different processes?

Hello Heinrich,
You can find in my new comments additional Document section.
I hope I could help.
