Internal auditing is a proven measure for quality management, and this article will explain why ISO 17025 internal audits are crucial to quality certification for testing and calibration laboratories.

Businesses need to deliver products of superior quality to stay competitive in their markets. To help businesses focus on the quality of their products, there are testing and calibration laboratories that evaluate products. However, testing these products in any laboratory may not properly assure that they will meet the standard of quality needed. Laboratories that have been certified for product evaluation and have passed the ISO 17025 internal audit will be able to assure the highest standard of product quality. Testing the products with a competent and certified laboratory will provide a higher level of satisfaction from customers, and other similar advantages.

Certification is regarded as a reliable indicator for quality management in businesses, and ISO 17025 is the key standard used for laboratories. Below we will explain the importance of ISO 17025 internal audits, and how they help laboratories get certified.

Implements Best Measures for Quality Measurement

Auditing emphasizes real quality improvement and ensures that a testing laboratory fulfils all the quality standards specified by regulatory bodies. A team of quality auditors will formulate a document with special criteria or conditions that the laboratory should meet, and confirm whether all the conditions of the quality manual are followed at every level of testing or calibration. Therefore, internal auditing will promote the best measures for testing in the laboratory which will eventually ensure that every product is of premium quality.

Sets Performance Goals

The other benefit of internal audits in laboratory certification is achieving performance goals. The auditing team will evaluate all the testing procedures of the laboratory and set goals to maintain the competency of each procedure. While most labs operate independently, getting a technical evaluation with an audit will help the laboratory know the key performance goals that are met by competitive laboratories in the same industry.

Assists in Attaining Other Quality Assurance Standards

Once a lab becomes highly competent in testing and calibration methods, it should complete the ISO 27001 internal audit. This audit helps to ensure proper IT security of products or software solutions that are processed by IT businesses. Therefore, a lab that has passed the ISO 27001 audit will be preferred by most businesses, including IT and non-IT companies.

These are three benefits that ISO 17025 internal auditing offers.

Here are some of the major advantages that businesses can enjoy when their products are examined by a certified laboratory:

• A systematic approach for quality control and assurance of their products,
• Recognition in the market by supplying premium-tested quality products,
• Greater awareness about quality maintenance among the employees,
• A rise in sales due in increased customer satisfaction,
• Great cost and time savings as there is no longer any need to re-test products.


There are many practical benefits from completing the ISO 17025 internal audit. These benefits include faster identification of issues in the equipment, measures for resolution, and meeting quality requirements for businesses. Businesses that have their products evaluated from a certified laboratory will enjoy higher customer satisfaction, enhanced customer loyalty, and good competitive advantages.
