Quality assurance is generally applicable to occasions with contracts, and its main purpose is to make users believe that products or services can meet the specified quality requirements. The content of quality assurance is by no means a simple quality assurance. Quality assurance is the task of quality control. Quality assurance is the basic purpose of providing "trust" on the basis of quality assurance. In international trade, an independent inspection agency with credibility, authority and detached position is often entrusted to inspect the damage degree and appraisal of goods. The quality inspection before product sales and the statistics of qualified products of our company are written proof to identify product quality. It is obtained through the quality inspection of products and equipment, and is the standard to ensure the product quality system.
