Road Test.Part

These laboratory tests may be followed by engine dynamometer tests (BS5117 Section 2.4 1985(1989)) and finally by road tests in working vehicles (BS 5117 Part 2 Section 2.5 1985 (1989)), thus completing the sequence of laboratory, field, service testing. 

Fuel cells have moved remarkably quickly from laboratory to road testing. The City of Los Angeles, California, USA, recently leased the first of five Honda FCX models as part of a demonstration program designed to generate real road data. And, DaimlerChrysler is currently testing 60 Mercedes-Benz "F-Cell" A-Class fuel cell vehicles with demonstration partners under everyday conditions.

The road test shouldn t be viewed as simply a required part of the driver qualification process. 

There is more to be gained from a road test than simply determining whether an applicant can drive a truck. The road test is not only a part of your qualification process — it is also part of your retention effort by helping you determine long-term fit. 

You ll note that, except for the road test, this section does not cover your regulatory requirements regarding driver qualifications. These issues have already been covered in detail in Part 391 as found in the Safety Compliance major tab.

The main value of salt-spray tests is in the evaluation of the effectiveness of phosphate coatings in restricting the spread of rust from scratches or other points of damage in a paint film. This feature is of particular interest to the motorcar industry, as vehicles are often exposed to marine atmospheres and to moisture and salt when the latter is used to disperse ice and frost from road surfaces. Great care is needed in the interpretation of a salt-spray test, as it has been found to favour thin iron phosphate coatings more than is justified by experience with natural weathering. In the motorcar industry the present custom is to use zinc phosphate coatings on the car bodies and all other parts exposed to the outside atmosphere.

We have applied this protocol to the evaluation of the measurement uncertainty for a method for the determination of three markers (Cl solvent red 24, Cl solvent yellow 124 and quinizarin (1,4-dihydroxyanthra-quinone)) in road fuel. The method requires the extraction of the markers from the sample matrix by solid phase extraction, followed by quantification by HPLC with diode array detection. The uncertainty evaluation involved four experimental studies which were also required as part of the method validation. The studies were precision, trueness (evaluated via the analysis of spiked samples) and ruggedness tests of the extraction and HPLC stages. The experiments and uncertainty calculations are described in detail in Part 2. A summary of the uncertainty budget for the method is presented in Fig. 3. 

In Part 1 [1] we described a protocol for the evaluation of measurement uncertainty from validation studies such as precision, trueness and ruggedness testing. In this paper we illustrate the application of the protocol to a method developed for the determination of the dyes Cl solvent red 24 and Cl solvent yellow 124, and the chemical marker quinizarin (1,4-dihydroxyanthra-quinone) in road fuel. The analysis of road fuel samples suspected of containing rebated kerosene or rebated gas oil is required as the use of rebated fuels as road fuels or extenders to road fuels is illegal. To prevent illegal use of rebated fuels, HM Customs and Excise require them to be marked. This is achieved by adding solvent red 24, solvent yellow 124 and quinizarin to the fuel. A method for the quantitation of the markers was developed in this laboratory [2]. Over a period of time the method had been adapted to improve its performance and now required re-validation and an uncertainty estimate. This paper describes the experiments under-...
