Performances testing

Provision for plant performance testing requires careful liaison between the appropriate personnel of both parties. Broad requirements of such tests will usually have been stipulated in contract documents but it remains for site teams to schedule the test arrangements in detail. These ate likely to include the selection and calibration of measuring devices together with the application of correction factors and tolerances, sampling and analyses, datalogging and effects of interruptions. It is important that procedures are drawn up and agreed upon well in advance of proposed test periods. 

For each acceptance area, after completion of the Cone Penetration Testing, the Contractor shall submit the results of the CPT testing to the Employer 

In the area of the ZLT, 4 CPTs shall be carried out prior to the ZLT being performed (one in each corner of the test zone). The Zone Load Test should generally be carried out and reported in accordance with the ICE Geotechnical Engineering Group Specification for Ground Treatment, 1987 (ISBN0-7277-0388-9). 

For preloading trials the Contractor shall surcharge the reclamation area by placing a 20 m sided square 6 m high trial embankment. If preloading is provided, this would be carried out when the reclamation has reached its final elevation. The trial embankment shall remain undisturbed for a period to be agreed with the Engineer. 

The fill formation shall have a CBR of 30% within the upper 300 mm of fill and shall thus be adequate for pavement design. 

The CBR test is generally used for pavement design. The pavement contractor will usually re-compact the top layer of the fill prior to the installation of the pavement. The influence depth of such a test is very 

These are reasonable questions, but reasonable answers are not so easily arrived at as performance failure can often mean significant costs to industry for repair of failures. In the case of the aerospace industry, severe failme may even mean loss of life. 

Reproducibility from one batch to the next, as well as pass rate within a single batch are also issues for non-chromate conversion coatings including CeCCs. As

The data in Table 7.6 also strongly suggest that the performance of the CeCC must be assessed and optimized on individual end-use alloys, and predicting coating performance of one member of an alloy type based on the performance of other members of the same type must be treated with considerable caution even

This requirement is important to ensuring that the CBMS II alarms for the correct agent. The requirement is for the CBMS II to produce substantially fewer false positive and false negative alarms and misidentilications than the current CWA and BWA detectors. The design of the CBMS II incorporates several features that improve selectivity over that of previous detectors. These include Cl and MS/MS, and for some target agents, MS/MS/MS. 

The ability of a system to meet its requirements and specifications must be demonstrated and documented before it can be accepted and fielded as a military system. Performance tests of a military detector system typically are performed by the contractor (Contractor Tests) and by the government (Government Tests). The former often are witnessed by government personnel who independently report on the methodology and results. Contractor testing is conducted at contractor facilities and at government facilities (but 

Contractor testing of liquid CWA performance was conducted in 2002, followed by Government Tests later that year. The latter test confirmed the good 

Several field tests have been carried out in 2000 and in 2003 to 2004 with the CBMS II and the DWSS installed in both the JSLNBCRS HMMWV and Stryker NBCRV platforms. These tests focused primarily on most aspects of

Testing—includes test specimen preparation, bond durabiHty tests, and stmctural performance tests.

Tables 2—5 Hst some typical properties or ranges of properties for the more common film and sheet products. Although these values are good for comparative purposes, actual performance tests are best to determine suitabiHty for use. Properties of multiple-layer films or sheets in laminar stmctures cannot always be predicted from values for the individual polymer layers. Use conditions of stress, temperature, humidity, and light exposure all strongly influence performance. Film and sheet manufacturers can recommend product combinations or variations that may provide significant performance advantages to the user.

The most effective specification is that which accomplishes the desired result with the fewest requirements. Properties and performance should be emphasized rather than how the objectives ate to be achieved. Excessive demonstration of emdition on the part of the writer or failure to recognize the usually considerable processing expertise held by the vendor results in a lengthy and overly detailed document that generally is counterproductive. Redundancy may lead to technical inconsistency. A requirement that cannot be assessed by a prescribed test method or quantitative inspection technique never should be included in the specifications. Wherever possible, tests should be easy to perform and highly correctable with service performance. Tests that indicate service life are especially useful. Standard test references, eg, ASTM methods, ate the most desirable, and those that ate needed should be selected carefully and the numbers of such references should be minimized. To eliminate unnecessary review activity by the would-be complier, the description of a standard test should not be paraphrased or condensed unless the original test is referenced. 

Wind Resistance. Asphalt shingles are certified to wind performance test standards on a continuous basis through independent third-party testing laboratories. Shingles that have passed the standard wind performance requirements, such as ASTM D3161, Standard Test Method for Wind Resistance for Asphalt Shingles, are identified by labels from the testing laboratory with whom they are in compliance. 

Performance. Consumer acceptance is a criterion on which cosmetic marketers caimot compromise. Whereas the likes and dislikes of consumers are in a state of constant flux, some product features are critical. A deodorant that does not deodorize or a hair coloring that fades in sunlight is unacceptable. Performance is tested by in vitro techniques during formulation, but the ultimate test of a product s performance requires in-use experience with consumers and critical assessment by trained observers. Performance tests can sometimes be combined with in-use safety tests, and protocols for such programs have been developed.

Subsequently, Calvert (R-19, p. 228) has combined mathematical modehng with performance tests on a variety of industrial scrubbers and has obtained a refinement of the power-input/cut-size relationship as shown in Fig. 14-130. He considers these relationships sufficiently reliable to use this data as a tool for selection of scrubber type and performance prediction. The power input for this figure is based solely on gas pressure drop across the device.

Arrester Testing and Standards Regulatory and approval agencies and insurers impose acceptance testing requirements, sometimes as part of certification standards. The user may also request testing to demonstrate specific performance needs, just as the manufacturer can help develop standards. These interrelationships have resulted in several new and updated performance test procedures. Listing of an arrester by a testing laboratoiy refers only to performance under a defined set of test conditions. The flame arrester user should develop specific application requirements based on the service involved and the safety and risk criteria adopted. 

When testing to estabhsh the thermodynamic performance of a steam turbine, the ASME Performance Test Code 6 should be followed as closely as possible. The effec t of deviations from code procedure should be carefully evaluated. The flow measurement is particularly critical, and Performance Test Code 19 gives details of flow nozzles and orifices. The test requirements should be carefully studied when the piping is designed to ensure that a meaningful test can be conducted.
