The need for check the quality and safety of the products marketed, and their components, through laboratory tests it is a necessity - and an obligation - well present at different levels of the marketing process. Whether they are highly structured companies operating on the global market, or small-medium enterprises aimed only at national trade, we tend to make use of services of pretesting of products, so as to prevent and identify any critical issues, to save in economic terms and streamline production processes.
The PRETESTING As partial testing
In the field of product certification, the term "pretesting" indicates a test carried out before final testing. This is an extremely important phase that allows you to know in advance if there are specific non-conformities. Very often pretesting takes the form of a partial test in which only some of the tests foreseen for the final test are performed. This trend is motivated by the interest in time and cost reduction, but also from the need to focus only on the aspects of the product considered critical. Often, Moreover, pretesting involves prototypes that will be subsequently integrated and completed; prototypes which, however, need to be evaluated in certain aspects.
THE ADVANTAGES OF PRETESTING
The resolution of problems at the origin allows you to significantly reduce the costs associated with changes and additions to the product. The increase in these costs, as is evident, it is exponential over time; think for example of all’economic impact of the need to replace a component at different times of the production process. Certainly a replacement made during design will have less weight than a change made after purchasing for production, or after assembly, after distribution, the sale.
In addition to the economic aspect, a great advantage connected to pretesting is the rapid access to markets, with the guarantee of a timely distribution of the products. Well present, Moreover, are the advantages linked to the need for safeguard the image of the company, reducing risks and responsibilities thanks to articulated and safe processes, avoiding the withdrawal of products from the market or any legal disputes.
To benefit from pretesting services, Moreover, is the whole design and manufacturing process. It is evident that providing for intermediate tests will allow simpler design and production processes, linear, easily amended and perfected.
In particular, pretesting is useful when a company adopts new technologies and solutions, perhaps in innovative or hitherto unexplored fields. It is less useful on consolidated products, for which the company has already acquired the solutions to achieve compliance.
the TIMES for the PRETESTING
As mentioned, it is very useful to carry out the activities of pretesting of the product at an early stage, since if a non-conformity is discovered it will be less expensive to remedy it. In some cases, But, pretesting is also used on finished products. This setting is useful if an already consolidated product is undergoing new certifications or if it is believed that there may be specific criticalities, linked to individual aspects.
In cases like this, this is done by performing subsets of tests, evaluating their outcome, before proceeding - if the pretesting has not brought to light the problems - to the tests in their entirety. Dividing the test campaign into two separate sessions - albeit involving some additional cost - results in a considerable savings in time and costs, where the pretesting reveals that there are changes to be implemented.
When pretesting is done on a finished product, of course, some of the tests may be held valid for the final test, without any need to repeat them. Otherwise, in case you test a intermediate prototype, you will need to repeat all the necessary tests.
