Comprehensive Guide to OIML R 35 Calibration of Large Weights Laboratory Testing Service
The International Organization for Standardization (ISO) and the International Committee for Weights and Measures (CIPM) have established various standards to ensure the accuracy and reliability of weights and measures. One such standard is OIML R 35, which governs the calibration of large weights.
Relevant Standards
ISO/IEC 17025:2017 - General requirements for the competence of testing and calibration laboratoriesEN 45501:2014 - Non-automatic weighing instruments - Part 1: Requirements for non-automatic weighing instruments to ensure accurate indicationsASTM E177-14: Standard Practice for Use of the International System of Units (SI)TSE ISO/IEC 17025:2017 - General requirements for the competence of testing and calibration laboratoriesLegal and Regulatory Framework
OIML R 35 is a legal requirement for certain industries, such as:
Weights and Measures Acts in various countriesEU Directive 2009/23/EC on the indication by labelling and standard product characteristics supplied to the consumerISO 9001:2015 - Quality management systemsInternational and National Standards
OIML R 35 is an international standard, but its implementation varies across countries. For example:
In Europe, EN 45501:2014 is a national standard for non-automatic weighing instruments.In the United States, ASTM E177-14 is a national standard for the use of the International System of Units (SI).In Turkey, TSE ISO/IEC 17025:2017 is a national standard for testing and calibration laboratories.Standard Development Organizations
International organizations involved in standard development include:
ISO (International Organization for Standardization)CIPM (International Committee for Weights and Measures)BSI (British Standards Institution)ASTM InternationalTSE (Turkish Standards Institution)How Standards Evolve and Get Updated
Standards are regularly reviewed and updated to reflect new technologies, scientific discoveries, or changing regulatory requirements. This ensures that standards remain relevant and effective.
Standard Numbers and Scope
OIML R 35 is a specific standard for the calibration of large weights. Its scope includes:
