What is product quality inspection?

Quality inspection (English: Quality Control) is the process of controlling and evaluating the quality of products or services to ensure they meet established quality requirements and standards. Therefore, the goal of this process is to prevent the production of poor-quality products or services that may affect the health and safety of users. Moreover, product inspection also helps businesses enhance customer trust and satisfaction with the product.

The product quality inspection process includes tasks such as: sample inspection, durability testing, safety testing, performance testing, and accuracy testing. In addition, statistical methods are often applied to determine the accuracy and reliability of inspection results.

Areas where product quality inspection is applied

Currently, product quality inspection is widely applied in various fields from industrial manufacturing, food, pharmaceuticals to services and technology. Accordingly, each field will have its own standards, processes, and quality standards established to ensure that products or services meet the requirements of customers and quality management organizations.

For example:

  • In automobile manufacturing: testing operational capability, safety testing, and emission standards testing.
  • In the food industry: testing food safety, nutritional quality, and flavor.
  • In the service sector: evaluating service quality and customer satisfaction.

Methods used to inspect product quality

There are many different methods used to inspect the quality of products and services. Here are some common methods:

  • Sample inspection: Using a small number of products to represent the entire batch, ensuring that the sample meets quality requirements.
  • Material inspection: Ensuring the quality of materials before use in the production process to ensure the quality of the final product.
  • Regular inspection: Performing regular inspections to ensure that goods or services meet quality requirements throughout the production and sales process.
  • Pre-shipment inspection: Ensuring the quality of products before shipment.
  • Standard-based inspection: Using established standards for comparison to ensure that the quality of goods and services meets requirements.
  • Manual inspection: Using manual techniques and tools to measure, visually evaluate, process samples, test durability, and accuracy of products.
  • Machine inspection: Using equipment and software for measurement and analysis to evaluate technical specifications, features, and product quality.

Product quality inspection process

Therefore, product quality inspection needs to be carried out regularly and according to the correct process to ensure accurate results. Here are the basic steps of conducting product quality evaluation:

Step 1: Determine the purpose of inspection

Firstly, the product quality inspection process needs to determine the purpose correctly to ensure that the process is carried out efficiently and appropriately. This includes determining specific quality standards such as: size, weight, durability, and accuracy established by functional agencies or manufacturing businesses.

Step 2: Choose inspection methods

Based on the nature of the product or service, the inspector can choose from various inspection methods including: sample inspection, measurement, synthetic testing, activity testing, sequential testing, etc. In particular, the selected product sample must represent the entire batch of products. This ensures accurate and reliable inspection results.

Step 3: Prepare inspection tools

Next, the inspector needs to prepare necessary tools to conduct product quality inspection. These tools include: measuring equipment, activity testing kits, and inspection samples. In addition, some products in special categories such as: biochemicals, pharmaceuticals,… may require some specialized tools to ensure the accuracy of inspection results.

Step 7: Implement corrective measures (if any)

Based on the product quality inspection results and inspection report, managers or owners need to implement corrective measures to improve product or service quality (if necessary). Additionally, inspection results should be stored, and reports should be provided to relevant departments to monitor the production process and address quality-related issues.
