Raw materials are tested using various methods, but there were no consistent standards in 2011. Testing is important to ensure appropriate materials are used for intended functions, as using the wrong materials can have serious consequences. Testing methods vary by industry and include corrosion resistance, environmental exposure, durability, fire, physical property analysis, metallurgy, and performance testing. Chemical analysis is important for pharmaceutical and chemical-based product manufacturers. Forensic analysis is applied to various industries and includes reverse engineering, mechanical testing, trace test procedures, fracture and failure testing, and chemical resistance testing.

There are a variety of methods used to test raw materials; however, there were no consistently applied standards for any industry during the year 2011. The methods used vary by industry and often consist of a variety of analytical test methods to include materials analysis, chemical analysis, failure analysis, composite analysis and forensic analysis. Testing of raw materials is considered important for the manufacturing process and for the performance of the final product. Manufacturers conduct such tests and analyzes in an effort to ensure that the raw materials they use are appropriate for their intended function. Using the wrong materials for a specific function can cause unintended consequences, such as serious side effects in medications or brake failures in cars.

Materials testing and analysis is used in a variety of industries to include aerospace, technology, building product manufacturing, or any industry that relies on physical materials to perform a substantial portion of the product’s intended function. Various methods for testing raw materials in these industries may include corrosion resistance tests, environmental exposure tests, durability tests, and fire tests. Other test methods may include physical property analysis and testing, metallurgy, and performance testing. Failure tests are also a very important part of the test material used in these industries and sometimes chemical analysis is also important in determining the reinforcing properties.

Chemical analysis methods for testing raw materials are important to both pharmaceutical companies and product manufacturers, especially those that produce chemical-based products, such as paints or pesticides. Several methods are usually employed; depending on the chemicals tested, this may include chemical trace analysis, screening tests, impurity tracking and testing, chemical compound analysis, contamination testing, and supporting research methods. With pharmaceutical companies, testing and ensuring drug dosing accuracy is imperative before manufacturing and releasing the drugs to market. Performed by qualified chemical scientists, chemical testing and analysis can help a manufacturer ensure both the safety of its products and their intended performance.

Forensic analysis is another important part of commodity analysis. More purely analytical, forensic analysis is applied to a wide range of industries, including industrial forensics, textile manufacturing, and pharmaceuticals. Methods used may include reverse engineering, mechanical testing, trace test procedures, fracture and failure testing, as well as chemical resistance testing and analysis. Forensic scientists usually conduct this type of test, and the results are often used in legal situations or presented to insurance companies.
