Meaning
Systematic verification processes confirm that a specific raw substance or component meets the technical requirements of an industrial application. Successful material qualification allows a supplier to be added to an approved vendor list for a particular project or company. This process ensures that the inputs to a manufacturing system are consistent and reliable.
Technical Approval
Engineers evaluate the physical, chemical and electrical properties of a sample against a set of predetermined specifications. The technical approval of a new substance involves testing its performance under various environmental conditions such as extreme heat or high pressure. These tests confirm that the material will not fail prematurely during the expected life of the finished product.
Compliance Verification
Regulatory bodies often require proof that the materials used in certain products do not contain prohibited substances. Compliance verification involves laboratory analysis and the review of safety data sheets provided by the manufacturer. For industries like aerospace or food packaging, this step is mandatory before any production can begin.
This documentation creates a legal record that the company has met its obligations to protect consumers and the environment.
Supplier Certification
Maintaining a high level of quality depends on the ability of the vendor to produce the same material over a long period. The supplier certification process includes an audit of the production facility and the quality management system of the provider. This ensures that the qualified material will continue to meet the required standards in future shipments.
