For many tests, the performance characteristics of the test samples are also measured at intervals during the exposure. The data obtained from product testing is pass or fail.

Test samples pass if they satisfy the product performance requirements after test exposure. For some products, information about changes in product performance as a function of amount of exposure to the test conditions can be obtained. If the test samples pass, the design team infers the materials are suitable for the application.

If the test samples fail, then the design team must determine the cause of the failure and correct it. With product testing as an approach to assessing the suitability of materials, the advantages are.

For materials testing, test samples can be individual components, individual joints between components, sub-assemblies, or just the materials being considered for components or joints. Many times, materials testing is performed without using the exact components that will be used in the final product.

The properties and characteristics of the materials and the test samples are evaluated before and after exposure, and often at intervals. The data is then used to guide component and joint design decisions, improving the likelihood of passing product testing.

The overarching benefit is the information will help design teams design components and joints that pass product testing, and possibly helping to reduce product development time. The only disadvantage of materials testing is the extra engineering resources required to perform the tests.

However, the reduced design times, increased certainty of passing product verification tests, and increased number of materials options are all benefits that justify the investment of time and money.

Design teams should focus on critical components and joints. Failure Modes and Effects Analysis FMEA can be used to identify the components and joints that pose the greatest risk to the reliability of a product and focus on those.

Materials reliability testing is a powerful approach for assessing material options for components and joints and gathering information that can be used to guide product design decisions. It takes time and effort to set up the testing, but the benefits of improved engineering decisions, optimized designs, and passing product reliability testing the first time are worth the expense.

Most engineers think of metallurgists only for failure analysis of component failures. While I do that, I also help design teams with component design. I help select alloys and coatings that have the corrosion, fatigue, wear, and creep properties needed to meet reliability requirements.

For example, this may be its warranty period or a reasonable lifetime that customers would expect. You can see evidence of this in some luxury cars, as they are good quality but are not always as well-known for reliability as, say a Toyota.

This could be down to their engineering being exact, so as soon as something goes slightly out of tolerance, the car will start to suffer from problems and may break down or at least show a warning. A mobile phone can be expected to survive drops from hand height, around 1 Meter, without the screen breaking, therefore a drop test will be needed.

But by testing the product under too extreme an environment, for example, you may be guaranteeing reliability at too high a level to be realistic which also costs too much.

For instance, testing a bottle at C is a very high temperature, double the boiling temperature for water. In fact, your bottle may only need to be tested to, say, 85C because it is not intended to hold boiling liquids at all, let alone liquid up to degrees! A reliability engineer will consult with you, understand your needs, and may suggest where testing needs to be less stringent which will also probably save time and money.

To get an idea of what kinds of testing requirements will be required for common consumer electronics, a typical niche for many importers and ourselves, here are some examples:.
