Factors influencing hardness measurement (P 11)

Hardness test blocks and indenters (P 12)

The Recommendation applies to glass "volumetric flasks", where the nominal capacity is marked by a single gauge mark on the neck.

Hardness standard equipment (P 13)

The unification of hardness measurement (P 14)

This Recommendation prescribes the general requirements which all gas volume meters to which it applies shall meet. Additional requirements are prescribed in the OIML Recommendations particular to the type of gas volume meter concerned.

Guide to calibration (P 15)

The provisions of this Recommendation apply to those thermometers called "clinical thermometers", of the mercury-in-glass type, with a maximum device, intended for measurement of the internal human body temperature.

Density measurement

This Recommendation applies to polarimetric saccharimeters that are graduated in sugar degrees (°Z) in accordance with the ICUMSA International Sugar Scale and that belong to the visual or photo-electric type.

Guidelines for the establishment of simplified metrology regulations (P 9)

This Recommendation defines: 1) The property of cereals known as the "Hectolitre Mass"; 2) the measuring instrument used for determining this property and adopted as the standard instrument by the Member-States of the International Organization of Legal Metrology; 3) The industrial and commercial instruments of the type accepted by the International Organization of Legal Metrology and meant for day-to-day measurement of this mass.

Guide on the categories of OIML Publications and their adoption procedures

This Recommendation specifies general, performance, efficiency and mechanical and electrical safety requirements, including test methods for type approval, for non-invasive mechanical sphygmomanometers and their accessories which, by means of an inflatable cuff, are used for the non-invasive measurement of arterial blood pressure.

Guide for CIML Members

Alphabetical list of terms defined in OIML Recommendations and Documents

This Recommendation applies to visual pyrometers and micropyrometers for measuring the radiance temperature of bodies in the visible and infrared parts of the spectrum, using the principle of the disappearing filament. Temperatures in the infrared part of the spectrum are measured using pyrometers having an eyepiece incorporating an image converter.

The role of measurement uncertainty in conformity assessment decisions in legal metrology

Surveillance of utility meters in service on the basis of sampling inspections

Guidance for defining the requirements for a certification system for prepackages

This International Recommendation specifies the metrological and technical requirements and test procedures for taximeters that are subject to national metrological control. It is intended to provide standardized requirements and testing procedures to evaluate the metrological and technical characteristics in a uniform and traceable way.

Electric Vehicle Supply Equipment (EVSE)

The purpose of this Recommendation and of these Tables is to harmonize at international level the basic data relating to the density and to the alcoholic strengths by mass and by volume of mixtures of water and ethanol, used in all countries by the Institutions and Administrations concerned (customs, finances, alcohol monopolies, etc).

Guide to the use of online technology for conducting CEEMS activities in a post-COVID world

This Recommendation lays down the principal metrological characteristics to which pressure gauges intended for the measurement of the inflation pressures in motor-vehicle tyres must conform.
