1. Product

Sérac Aero SA-1, a carbon fibre ski roof box, 2100 × 960 × 395 mm, 19 kg, rated load 75 kg, rear-opening lid with two gas springs, 5 latch points and a key lock. It mounts on standard aero or square crossbars with four clamps (2 × M8 each, 10 N·m), crossbar spacing 605 to 755 mm.

The box will be sold in the EU under the General Product Safety Regulation (EU) 2023/988. We want a type test to ISO 11154:2023 (roof load carriers) as the basis of the technical file, with a test report we can quote in the manual and on the label.

2. Tests requested

Please quote each item and the complete package:

No.	Test	Reference	Notes
T1	Static load: rated load 75 kg × safety factor, deflection and residual deformation of floor, clamps and crossbars	ISO 11154:2023	box mounted on a representative crossbar set supplied by us
T2	Clamp retention: longitudinal, lateral and vertical pull on the mounted box	ISO 11154:2023	report slip force and failure mode
T3	City Crash: 30 km/h and 50 km/h deceleration sled test with the box loaded to 75 kg, forward and lateral	ISO 11154:2023 "city crash" / DIN 75302	pass criterion: box and load stay on the vehicle, no part of the box or load leaves the roof area
T4	Lid: pressure or lift test representing 200 km/h airflow, lock and latches engaged	ISO 11154:2023	we expect ~600 N lift resultant, latch reaction max 130 N (our FEA)
T5	Vibration and fatigue: road simulation, closed lid, rated load	ISO 11154:2023	state the profile and duration you use
T6	Environmental: cold (−30 °C) latch and gas-spring function, UV weathering of the clear coat (optional)	ISO 4892-2 for UV	optional, quote separately
T7	Lock: key removable only when locked, lid cannot open with the key removed, after T5	internal spec
T8	Wind noise and aerodynamic lift at 130 km/h (wind tunnel)	optional	quote separately if available

Two first-article boxes (one for destructive tests), each with clamps and straps.
Crossbars: Thule WingBar Evo or equivalent on a test roof, or a rig of your choice; please state what you prefer.
Ballast: we can supply ski-shaped ballast; otherwise sandbags to 75 kg.
Technical file extract: drawings, FEA report, laminate plan, user manual draft.

4. Deliverables

Test report in English with pass/fail per test and measured values, photos and video of the City Crash sled runs.
Statement whether the product meets ISO 11154:2023 for use with the rated load.
Optional: certification mark / listing (TÜV, GS or equivalent) and the terms for using it.

5. Questions

Which standard editions and sled profiles do you test to (ISO 11154:2023, DIN 75302, your own)?
Lead time from receipt of samples to report.
Cost per test and for the full package, and whether a retest after a design change is priced lower.
Do you need the box mounted by us, or will your technicians mount it per our manual (preferred, as a usability check)?
