when it has been submerged for at least 18 h.
9.4 Floatation material
Floatation materials shall meet the requirements in 9.4.1 to 9.4.7 as listed in table 6 when used in the enginecompartment
bilge, and engine compartment or bilge, unless located in a sealed compartment.
9.4.1 Vapour test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed in a fully saturated
petrol vapour atmosphere for 30 days at a minimum temperature of 38 °C.
9.4.2 24-hour petrol test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 24 h at
23 °C ± 2 °C in reference fuel B of ASTM D 471:1996 or equivalent fuel.
9.4.3 30-day petrol test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 30 days at
23 °C ± 2 °C in reference fuel B of ASTM D 471:1996 or equivalent fuel.
9.4.4 24-hour oil test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 24 h at
23 °C ± 2 °C in reference oil No. 2 of ASTM D 471:1996 or equivalent lubricant.
9.4.5 30-day oil test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 30 days at
23 °C ± 2 °C in reference oil No. 2 of ASTM D 471:1996 or equivalent lubricant.

9.4.6 24-hour bilge cleaner test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 24 h at
23 °C ± 2 °C in a 5 % solution of trisodium phosphate in water.
9.4.7 30-day bilge cleaner test
The floatation material shall not reduce in buoyant force by more than 5 % after being immersed for 30 days at
23 °C ± 2 °C in a 5 % solution of trisodium phosphate in water.
NOTE The buoyant force reduction in items 9.4.1 to 9.4.7 may be measured in accordance with ASTM D 2842.

10 Steering system test
Component test are intended to establish minimum acceptable design criteria for components of steering systems.
Each steering system, including helm, cable, and attachment components, shall withstand an axial cable load of
630 N in tension and compression, applied at the connection to the jet drive, throughout its travel range, without
severance of components.
10.1 Axial force test
A 540 N push-pull force shall be cycled for 10 tension-to-compression cycles at a duration of 5 s, applied as
appropriate:
— distributed over not more than 100 mm of a hand grip of handle bar, applied axially to the pivot shaft.
10.2 Tangential force test
A 360 N force in either direction shall be cycled from zero-to 360-to-zero for 10 cycles at a duration of 5 s, applied
