Comprehensive Guide to OIML R 35 Calibration of Heavy Weights Laboratory Testing Service by Eurolab
OIML R 35 is a international standard published by the International Organization for Legal Metrology (OIML) that outlines the requirements for the calibration of heavy weights. The standard ensures that the weights used in trade and commerce are accurate and reliable, which is essential for maintaining fair trade practices and preventing economic losses.
The OIML R 35 standard is based on ISO/IEC 17025:2017 (General Requirements for the Competence of Testing and Calibration Laboratories), which sets out the requirements for testing and calibration laboratories to ensure that they operate in accordance with a quality management system. The standard also references other international standards, such as ISO 9001:2015 (Quality Management System) and EN ISO 376:2010 (Verification by comparison).
In addition to OIML R 35, there are several national standards that govern the calibration of heavy weights in different countries. For example:
Industry-Specific Standards
The standard requirements for the calibration of heavy weights vary depending on the industry. For example:
Evolution of Standards
Standards evolve over time to reflect advances in technology, changes in regulatory requirements, and improvements in testing methods. The OIML R 35 standard has undergone several revisions since its initial publication in 1984.
The latest version of the standard, OIML R 35:2019 (Calibration of Heavy Weights), was published in 2019 and includes updates to the measurement uncertainty requirements and the verification procedures.
Standard Compliance Requirements
Industry and regulatory compliance with standards is crucial for maintaining fair trade practices, preventing economic losses, and ensuring public safety. Companies that fail to comply with standard requirements may face serious consequences, including fines, penalties, and reputational damage.
The following are some of the key standard compliance requirements:
The OIML R 35 standard is essential for ensuring that heavy weights are accurate and reliable. The standard provides a framework for laboratories to follow when calibrating heavy weights, which helps to ensure that the weights used in trade and commerce are trustworthy.

Recommendations
To ensure compliance with the OIML R 35 standard, we recommend that laboratories:
Test Methodologies and Equipment
We recommend using certified reference standards, measurement uncertainty calculations, and verification procedures to ensure compliance with the OIML R 35 standard.
Interpretation and Evaluation of Results
We recommend that laboratories interpret and evaluate results from calibration testing in accordance with the OIML R 35 standard.
Quality Management System (QMS)
We recommend developing a QMS that meets the requirements of ISO 9001:2015 to ensure compliance with the OIML R 35 standard.
Calibration Certificate
We recommend issuing a calibration certificate by a laboratory that has been accredited or certified by a recognized accreditation body. The certificate must include all relevant information, including the weight range, measurement uncertainty, and verification data.
By following these recommendations, laboratories can ensure compliance with the OIML R 35 standard and maintain accurate and reliable weights for trade and commerce.
