QA, QC & Testing

Requirements In Action

In the UK, vehicles that are over three years old are required by law to undergo a compulsory test to ensure that they are road worthy. (Interesting to note that there is no test in the USA where any vehicle irrespective of condition can be driven on the roads).

How are vehicles checked for road worthiness?

Are they driven to see if they drive ok?

Are brakes slammed on to see if the car stops?

MOT

To ensure that that vehicle is road worthy, the Ministry of Transport, a government body has developed a series of checks where vehicles over three years old must meet to be classed as roadworthy. By meeting these checks the vehicles can be insured and taxed to be used on the roads.

The number of checks, the type of checks and the detail of the checks conducted form the MOT test. (MOT is an abbreviation of Ministry Of Transport).

These checks are the requirements of the MOT and the vehicle must be checked against these MOT requirements.

Vehicles that meet the checks, pass the MOT requirement and are allowed to be driven on the UK's roads. Vehicles that fail to meet the requirements set in the MOT are not allowed to be used unless any faults found are rectified. There are heavy penalties for using defective vehicles on UK roads including fines and driving license endorsements.

As an example, the MOT requirement for the safe level of tyre tread is 1.6mm. If the vehicle being tested has a tyre with less than this level of tread, the vehicle has failed to meet the minimum requirement level set for tyre tread and will subsequently fail the MOT test.

FMVSS

In the USA the National Highway Traffic Safety Administration issues Federal Motor Vehicle Safety Standards (FMVSS) and Regulations to which manufacturers of motor vehicle and equipment items must conform and certify compliance.

The FMVSS safety standards and regulations are requirements set by the National Highway Traffic Safety Administration. Vehicle manufacturers have to ensure that their motor vehicles and equipment meet these requirements.

"Each hydraulic brake hose assembly shall have permanently attached brake hose end fittings which are attached by deformation of the fitting about the hose by crimping or swaging." (Sec. 571.106 Standard No. 106; Brake hoses. S5.1 Construction. section [a])

The above excerpt defines a requirement for the vehicle brake hosing by the FMVSS. Failure to comply with this requirement could lead to prosecution and the imposition of restrictions on vehicle sale in the USA.

Both the MOT and the FMVSS provide a set of requirements which need to be adhered to.
