Prototype test

Discuss the relative merits of the prototype testing of automotive vehicles for certification and of certification based on production line testing of each vehicle produced. 

Because of the foregoing requirements, a sophisticated organization is needed to do an effective job of new installation control. Prototype testing is best handled at the national level installation testing and plan examinations at the state, provincial, or regional level. Location of owners is a local operation with respect to residential and commercial structures but may be a state or provincial operahon for industrial sources. 

Discuss the application of the prototype testing-replicate approval approach to stationary air pollution sources. 

The example demonstrates that operating the compressor off the built-in pressure ratio means operating at a lower efficiency. This could be anticipated from Figure 4-3. The optimum port configuration for the various types of screw compressors was determined from a series of prototype tests. The change in volumetric efficiency is not a result of the built-in volume ratio, but is due to the increased slip (internal leak " n... 

Pre-launch occurs after prototype testing and prior to full production. Additional inspections and tests may be needed until the production processes have been validated and process capability assured. The additional checks serve to contain nonconformities until variation has been brought within acceptable limits for production.

FEA does not replace prototype testing rather, the two are complementary in nature. Testing supplies only one basic answer about a design that either passed or failed. It does not quantify results, because it is not possible to know from testing alone how close to the point of passing or failing a design actually exists. FEA does, however, provide information with which to quantify performance. 

There are of course products whose shapes do not approximate a simple standard form or where more detailed analysis is required, such as a hole, boss, or attachment point in a section of a product. With such shapes the component s geometry complicates the design analysis for plastics, glass, metal, or other material and may make it necessary to carry out a direct analysis, possibly using finite element analysis (FEA) followed with prototype testing. Examples of design concepts are presented. 

After obtaining the prototypes, tests must be made to determine the utility. Generally these include a short time destructive test to determine the strength and to check out the basic design. Another test that is done is to use the product in the projected environment with stress levels increased in a rational manner to make for an accelerated life test. Other tests may include consumer acceptance tests to determine what instructions in proper use are required, tests for potential safety hazards, electrical tests, self-extinguishing tests, and any others that the product requires. In the case of high risk products, the test program is continued even after the product enters service. 

Redesign the product if necessary based on the prototype testing. 

DV refers to the series of procedures used by the product development group to ensure that a product design output meets its design input. It focuses primarily on the end of the product development cycle. It is routinely understood to mean a thorough prototype testing of the final product to ensure that it is acceptable for shipment to the customers. 

Determination of the hazard potential and designing to eliminate the hazard is one element of the solution. The use of carefully designed accelerated and continuous prototype testing is another element. The instruction in use and proper maintenance procedure is the third element. By exercising judgment as to the appropriate combination of these elements consistent with the economic factors involved, the designer can have a product that will perform for its projected design life with... 

Operating parameters of the prototype equipment are used for running the prototype tests. These parameters are also used in running the basic study tests, but in a wider range to prove the validity of the basic correlations under broader conditions. 

The prototype test results are correlated by using the operating parameters directly, while the basic study test results (including photographic records and experimental measurements) are used in microscopic analysis based on the local flow characteristics and their constitutive correlations.

Because of the sensitivity of friction to so many variables, it is often desirable, if not essential, to test the actual product in a prototype test rig. Certain of the slip resistance tests have headed in that direction by using complete shoes as the slider. Similarly, instrumented systems are used to investigate the grip of tyres under real road conditions. Generally, a product test rig will be the best approach for items such as bottle closures and bearings. 

In contrast to the technology described in item 2.2 the present one has yet no experience of commercial usage, but only prototype tests at realistic flow rates ( 500 MMscm/y) for solving problems A), B) from the list above. 

In the modified baseline process for Pueblo, frozen munitions will be conveyed to six agent accessing machines operating in parallel and sized to handle 27 munitions per hour each (Tomanek, 2000a, 2000b). These will not be baseline system MDMs but new machines that would have to be developed and tested. Prototype testing would take place at the Chemical Demilitarization Training Facility in Aberdeen, Maryland.

A comparison of experimentally determined failure times for different stress levels and those predicted by the above equation for epoxy-aluminum lap shear joints aged at 60°C and 95 percent RH is presented in Table 15.3. These results indicate that the reaction rate method is satisfactory for predicting the effects of temperature and stress on the lifetime of adhesive bonds, provided that failure is cohesive within the adhesive. This, of course, should be validated by prototype testing. 

Substitution is a difficult task because the specific ingredients will control the application and end-use properties of the epoxy adhesive. Any substitution of material generally requires that the complete product be reverified with production and prototype testing. Of course, the health and safety issues of any alternative material must also be carefully considered to ensure that it is actually safer. 

Unlike many laboratory and prototype testing facilities, which are hampered by major problems when commercially installed, these engines were developed and tested in a "working environment. These operating conditions are typically encountered at site installations.
