Methods of checking product quality

Quality is a decisive factor in determining the true value of a product or service. To ensure that every product/service offered reaches its optimum level of quality, multiple testing methods need to be applied. Each method provides a quality look. Below are the necessary and commonly used quality control methods today.

Check production materials

The quality of the final product depends largely on the quality of the input materials. It can be said that this is one of the most important factors to create product quality. Therefore, it is necessary to establish a process for checking the quality of input materials in enterprises, especially manufacturing enterprises.

 

Methods of testing raw materials for production

Testing raw materials before use in the production process helps eliminate the risk of producing poor quality products. You can check the ingredients by:

• Supplier reviews

• Review material specifications
• Evaluate the physical condition of the material: shape, color, taste,...
• Check records and documents on production processes

Record and maintain detailed records of inspections, tests and corrective actions performed to maintain traceability and accountability where necessary.

Statistical Process Control (SPC)
Use statistical techniques to monitor and control manufacturing processes, ensuring that they remain within acceptable quality limits.

Check product samples

Sample testing is a method of using a small number of product samples to represent the entire batch. This helps minimize time and resources, while still ensuring the quality of all products in the shipment. To do so, the sample being tested must:

Represents the characteristics of an item.

Must have stable properties throughout the sample storage and preservation period.
Sampling must comply with proper specifications, tools, method of sampling and quantity of each specific type of product according to regulations.

Check according to standards

Standards are developed and issued based on experience and highly specialized knowledge. Quality testing according to standards helps determine the level at which the desired quality is achieved. To check, it is necessary to determine what regulations and standards exist for the product. Determining the correct standards helps inspections not to miss important criteria.
