Control & testing

Inspection and testing are crucial steps in the manufacturing process to ensure that products meet specifications, quality standards and customer requirements. These processes are necessary to identify any defects or deviations before the products reach the end user.

Control

Control involves monitoring and reviewing products and processes throughout the manufacturing cycle. It covers the following aspects:

Incoming control:

This is the first level of control where materials and components received from suppliers are reviewed to ensure they meet specified requirements and standards.

Process control:

During the manufacturing process, products are monitored and controlled to ensure they are manufactured to specifications. This may include monitoring of machine parameters, measurements of dimensions and inspection of visual quality criteria.

Final check:

Before products are released for delivery, they undergo a final check to ensure that all quality requirements have been met. It may include functional tests, aesthetic inspections and verification of documentation.

Testing

Testing involves specific procedures and protocols to verify that products function according to their intended purpose and specifications. This includes:

Function test:

Test to ensure that the product performs the functions it is designed for. It may include electrical tests, mechanical tests or performance tests depending on the product.

Durability test:

Testing to assess how the product copes with different conditions and usage scenarios over time. This may include load tests, vibration and shock wave tests.

Environmental test:

Testing to assess the performance of products under various environmental conditions, such as temperature variations, humidity, corrosion resistance, etc.

Safety test:

Testing to ensure that the product meets safety requirements and regulations applicable to the specific market or industry.

Verification and validation

Verification and validation are two important aspects in control and testing:

Verification:

Confirmation through objective evidence that requirements have been met. It is about ensuring that the product is built correctly according to the specifications.

Validation:

Confirmation by objective evidence that the requirements for a specific use or application have been met. It is about ensuring that the product functions correctly in the environment or context of use for which it is intended.
