Principles of selection of characteristics for the examination of measuring instruments

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.

Principles of assurance of metrological control

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.

The use of certified reference materials in fields covered by metrological control exercised by national services of legal metrology. Basic principles

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.

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.

Guide to portable instruments for assessing airborne pollutants arising from hazardous wastes

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).

Principles for metrological control of equipment used for verification

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.

Total radiation pyrometers

This Recommendation applies to the "metre standard" used by Verification Officers for verifying: line, or end length, rigid measures, for which the maximum permissible error exceeds 300 micrometres per metre (i.e. 0.03 % in relative value).

Vortex meters used in measuring systems for fluids

Glass delivery measures - Automatic pipettes

This Recommendation applies to medical syringes with glass barrels, intended for general use. The Recommendation does not concern syringes for insulin, syringes for tuberculin or syringes with barrels of a substance other than glass, e.g. of plastic.

Guide for the application of ISO/IEC Guide 65 to assessment of measuring instrument certification bodies in legal metrology

This Recommendation applies to capacity measures made of glass (or other authorised materials) known as "serving measures" which are usually filled as required and which are used for the retail sale of drinks, such as: milk, beer, wine, mineral waters, various table waters, spirits, etc. sold in cafes, restaurants, hotels, canteens, etc. for consumption on the premises.

Guide for the application of ISO/IEC 17025 to the assessment of Testing Laboratories involved in legal metrology

This Recommendation applies to "gauge blocks of rectangular section", which are measures of length in the form of rectangular plates or parallelepipedal rectangular blocks comprising two opposing, flat, mutually parallel, faces, called measuring faces, whose surface quality is such that they have the property of wringing to the corresponding faces of other gauges or plane datum surfaces. It lays down the principal technical specifications relating to their intended use, their manufacture, their qualities, their inspection.

General requirements for software-controlled measuring instruments

This Recommendation applies to diaphragm gas meters, that are gas volume meters in which the gas flow is measured by means of measuring chambers with deformable walls, including gas meters with a built-in temperature conversion device.

Guide for the application of ISO/IEC 17065 to assessment of certification bodies in legal metrology

This Recommendation applies to: (1) rotary piston gas meters in which internal walls defining the measuring chambers are set in rotation and the number of revolutions of these walls represents a measurement of the volume of the gas passed; (2) turbine gas meters where the gas flow rotates a turbine wheel and the number of revolutions of this wheel represents the volume of the gas passed.
