8.8 SUPPORT STANDS CODES 7520.350 AND 7520.351 FOR
PLATES OF FIBER REINFORCED POLYMERS
8.8.2 COMPONENTS IDENTIFICATION
The Support Stands code 7520.350 and 7520.351are used for impact tests on plates of
fiber reinforced polymers according to the following standards:
- ASTM D 7136M, AIRBUS AITM 1.0010 (for code 7520.350).
- ASTM D 7136, BOEING BBS 7260, SACMA SRM2R-94 (for code 7520.351).
8.8.1 INTRODUCTION
Notes:
• The range of temperature endured by the clamps during the impact tests is -20 to 80 °C.
• For
non-instrumented tests (test controlled directly from the control box of the instru-
ment): the stands must be configured as “Adjustable height stand”;
• For
instrumented tests (test controlled through the software on PC): the stands must
be configured on the “Visual Impact” program as “Fixed height stand” and with CAI/
Rebound method.
