Aim:

To decide whether the given design passes the European standards or not.

European Regulation Requirement:

• Measure the distances between the points on the wheel circle and fender curve. All of these should be greater than 10mm to satisfy European regulations.
• Horizontal distances from SA, SB, and SC points to the fender curve should be at least 5mm.

Given design:

Sketch has been made according to the standards:

Measure the distance between the at the 5 section

SA-SA

25.992 mm > 10 mm

SB-SB

43.64 mm > 10 mm

SC-SC

38.36 mm > 10 mm

SD-SD

47.625 mm > 10 mm

SE-SE

60.115 mm > 10 mm

Now to find the horizontal distance between the wheel and the fender. This distance should be at least 5mm from SA point, SB point, and SC point.

Distance between SA point and fender outer curve = 9.949 mm (pass)

Distance between SB point and fender outer curve = 10mm (pass)

Distance between SC point and fender outer curve = 2.434 mm (pass)

Result:

Region	Required clearance	Actual clearance	Result
SA-SA	10	25.992	PASS
SB-SB	10	43.64	PASS
SC-SC	10	38.36	PASS
SD-SD	10	47.625	PASS
SE-SE	10	60.115	PASS

Horizontal result from the outer curve of the fender

From outer curve the fender to	Distance	Result
SA	9.494>5	PASS
SB	5.698>5	PASS
SC	2.434<5	FAIL

Conclusion:

The given design satisfies all European standards but one, i.e. the distance from the SC point to the fender curve (which is just 2.434 mm), which is way below the recommended 5 mm minimum distance. Therefore, this fender cannot pass European standards. The design should be reverted back to the class A designer telling him to modify the design and increase the gap there.
