What Are the Requirements of DIN EN ISO/IEC 17025:2018-03?
The requirements of DIN EN ISO/IEC 17025:2018-03 are divided into two categories:
- Requirements for the management system of the laboratory
- Requirements for the technical competence of the laboratory
Requirements for the Management System of the Laboratory
The management system requirements include the need to implement and maintain a quality management system that ensures continuous improvement of the laboratory's work. This includes, among other things, document management, process control, planning and implementation of internal audits, and good resource planning.
Requirements for the Technical Competence of the Laboratory
The requirements for the technical competence of the laboratory include, among others, the validation of test methods, ensuring the traceability of measurement results to national or international standards, performing calibrations and monitoring environmental conditions. The technical competence of the laboratory is also determined by the qualifications and skills of the personnel and by the equipment of the laboratory.
Compliance with these requirements ensures that the laboratory performs reliable and accurate work when performing tests and calibrations. Only by fully implementing these requirements can the laboratory achieve accreditation according to DIN EN ISO/IEC 17025:2018-03.
How Is Accreditation According to DIN EN ISO/IEC 17025:2018-03 Achieved?
Accreditation according to DIN EN ISO/IEC 17025:2018-03 is awarded by an independent accreditation body. To obtain accreditation, the laboratory must apply for accreditation and demonstrate during the accreditation process that it meets all the requirements of DIN EN ISO/IEC 17025:2018-03.
The accreditation procedure includes the following essential steps:
- First, the laboratory must submit an accreditation application form informing the accreditation body about the type of tests and calibrations performed by the laboratory. The laboratory must provide information on its competencies and experience.
- The accreditation body shall subsequently examine the documents submitted by the laboratory. The laboratory shall provide meaningful documentation for all requirements according to DIN EN ISO/IEC 17025:2018-03.
- In the following, an audit of the laboratory is carried out on behalf of the accreditation body to ensure that all requirements of DIN EN ISO/IEC 17025:2018-03 are met. The assessment is carried out by experienced professionals who evaluate the laboratory's compliance with the management system requirements and technical competence.
- If the laboratory meets all the requirements of DIN EN ISO/IEC 17025:2018-03, the accreditation body will issue an accreditation which is normally valid for a period of several years. The laboratory must periodically demonstrate that it continues to meet all requirements of DIN EN ISO/IEC 17025:2018-03 to maintain accreditation.
Accreditation to DIN EN ISO/IEC 17025:2018-03 is an important demonstration of laboratory competence and quality assurance and helps to increase the confidence of customers and partners in the laboratory's work.
What Are the Benefits of DIN EN ISO/IEC 17025:2018-03 Accreditation for a Laboratory?
DIN EN ISO/IEC 17025:2018-03 accreditation offers laboratories various advantages. First of all, accreditation is proof of the laboratory's competence and quality assurance. This can help to strengthen the confidence of customers and partners in the work of the laboratory.
In addition, DIN EN ISO/IEC 17025:2018-03 accreditation can help to improve the efficiency and effectiveness of the laboratory.
