Laboratories: Testing

Testing the performance and effectiveness of products are usually conducted through laboratories testing services. Some critical product must be tested such as food to ensure that it is safe for human consumption. The food items that are tested in labs include manufactured and processed food, crops and those served at food establishments. They will check the nutritional value of food; make sure it does not contain allergens, monitor the radiation level in food and make certain that it would not bring foodborne illnesses when consumed.


Processed and manufactured food such as canned goods, beverages, cereal and others need to be labeled with the amount of calories, sodium, fat, carbohydrates and other nutrients on their packaging. Laboratories testing services will determine if the food contains the required nutrients and each of their amounts to put on the label. Food may also contain ingredients that may cause allergies to people. Some common allergens are widely consumed food such as egg, bread, pasta, peanuts and shellfish. In order to prevent people to get allergies because of consuming a certain food product, allergen testing is conducted. Whether radiation in food is helpful or harmful to people depends on the level the food contains. Low radiation levels can actually kill potential harmful bacteria. However, high levels of it in food may result to serious danger to health. Monitoring radiation levels applies both to raw and manufactured foods as the radiation may come from the water or soil that contaminates the crop. Besides radiation, other factors that can contaminate food are chemicals, disease-carrying pathogens and other harmful substances. Examples of foodborne illnesses and diseases are salmonella and campylobacter which results when raw or undercooked poultry is consumed.


In various fields, material testing, also referred as destructive testing, is done to make sure that a product and its parts will act upon its intended use and would not wear easily from constant use. The report the laboratory testing services creates serves as a guide to quickly pin point the root cause of material failure. Material testing encompasses various types of tests such as chemical analysis, metallurgical testing, mechanical testing, corrosion testing and RoHS testing. A field that requires this type of testing is the construction. Construction materials are needed to be tested for various reasons such as durability and its ability to withstand stress to name a few. Getting laboratories testing service has several advantages. Some laboratories made their testing area fully equipped with all the testing tools. This means all the necessary testing a company needs can be conducted in one facility. This brings efficiency and faster turnaround time. Some laboratories testing services can also help in verifying and selecting materials.


In contrast to material testing, non-destructive testing is also offered by laboratories testing services. Non-destructive testing is the process of detecting defects in surface and sub-surface without harming the materials or products. It will also check the adequacy of materials such as welders, pipe, castings, fasteners and other metal products as well as ceramic items including their parts. They will also determine the proper procedure to execute.


Part of laboratories testing services is calibration. Calibration services will set the instrument to perform according to the measurement standard. Well-calibrated equipment will ensure that an equipment produce results that are in par or above the standard.
