Application errors

Application of the test substance to the test system is without doubt the most critical step of the residue field trial. Under-application may be corrected, if possible and if approved by the Study Director, by making a follow-up application if the error becomes known shortly after the application has been made. Over-application errors can usually only be corrected by starting the trial again. The Study Director must be contacted as soon as an error of this nature is detected. Immediate communication allows for the most feasible options to be considered in resolving the error. If application errors are not detected at the time of the application, the samples from such a trial can easily become the source of undesirable variability when the final analysis results are known. Because the application is critical, the PI must calculate and verify the data that will constitute the application information for the trial. If the test substance weight, the spray volume, the delivery rate, the size of the plot, and the travel speed for the application are carefully determined and then validated prior to the application, problems will seldom arise. With the advent of new tools such as computers and hand-held calculators, the errors traditionally associated with applications to small plot trials should be minimized in the future. The following paragraphs outline some of the important considerations for each of the phases of the application. 

Improvement of durability in thin films making application errors less damaging [5.55]. 

To start Event Viewer, log in as an administrator (or equivalent) and go to Start > Programs > Administrative Tools > Event Viewer. Erom here you can view the System, Application, and Security log files. The System log file displays alerts that pertain to the general operation of Windows. The Application log file logs server application errors. The Security log file logs security events such as login successes and failures. These log files can give a general indication of a Windows computer s health. 

User interfaces designed that tap into users mental models is a strategy that generally increases intuitive processes and reduces application errors (Johnson et al. 2005). Moreover, efforts made to attune a user interface to the users mental models often reduces the time needed for training. Together these benefits help to improve user productivity and reduce costs (Preece et al. 1994). 

Single operator and maintenance training requirements However, in such cases there is every possibility that there may be some compromise with safety system/SlS. These integrated solutions may offer some cost benefit but may be at a cost protection sacrifice against common cause and systematic design and application errors. 

An overview is presented of the reasons for construction sealants failing in the real world . These reasons are categorised by design errors, such as improper joints sizing, application errors, such as lack of surface preparation, and lastly material failures. 1 ref. 

The major components affecting the life of paints is the application error and one controlling factor is the inappropriate design or the complexity of the equipment which prevents the proper application of paint.
