Traceability is most often obtained by calibration, establishing the relation between the indication of a measuring instrument and the value of a measurement standard. These standards are usually coordinated by national metrological institutes: National Institute of Standards and Technology, National Physical Laboratory, UK, etc. Traceability is used to extend measurement from a method that works in one regime to a different method that works in a different regime. An example would be the measurement of the spacing of atomic planes in the same crystal specimen using both X-rays and an electron beam. Traceability also refers to the methodology used to calibrate various instruments by relating them back to a primary standard. Traceability, accuracy, precision, systematic bias, evaluation of measurement uncertainty are critical parts of a quality management system. Mistakes can make measurements and counts incorrect. Even if there are no mistakes, nearly all measurements are still inexact. The term «error» is reserved for that inexactness, also called measurement uncertainty. Among the few exact measurements are:

– The absence of the quantity being measured, such as a voltmeter with its leads shorted together: the meter should read zero exactly.

– Measurement of an accepted constant under qualifying conditions, such as the triple point of pure water: the thermometer should read 273.16 Kelvin (0.01 degrees Celsius, 32.018 degrees Fahrenheit) when qualified equipment is used correctly.

– Self-checking ratio metric measurements, such as a potentiometer: the ratio in between steps is independently adjusted and verified to be beyond influential inexactness.

All other measurements either have to be checked to be sufficiently correct or left to chance. Metrology is the science that establishes the correctness of specific measurement situations. This is done by anticipating and allowing for both mistakes and error. The precise distinction between measurement error and mistakes is not settled and varies by country. Calibration is the process where metrology is applied to measurement equipment and processes to ensure conformity with a known standard of measurement, usually traceable to a national standards board.

Grammar and spelling quiz

Find and correct the grammar and spelling mistakes in the following passages a) Scientific metrology

Scientific metrology are an uantity of metrology. It deal of the establishmen of uantity system, unit system. Scientific metrology develop new methods of measurement. S cientific metrology are called also fundamental metrology. It help to implement all of the measurement standards into practice. Scientifc metrology transfer traceability from the standards to in society users. This sub field of metrology play a important role in society life.

b) What is traceability?

Traceability is o btained by calibration often. Calibration establishe t he relation between the indication of an m easuring instrument and an value of a measurement standart. These standards is u sually coordinated with n ational metrological institutes: National Institute of Standards and Technology, National Physical Laboratory, UK, etc. Traceability are use to extended measurement from a method that work in one regime to a different method who work in a diferent regime. An example would be the measurement of the spacing of atomic planes in the same crystal specimen using both x-rays and an beam electron.

Ex. 1. Read and translate the text Applied metrology

Metrology laboratories are places where both metrology and calibration works are performed. Calibration laboratories generally specialize in calibration work only.

Both metrology and calibration laboratories must isolate the work performed from influences that might affect the work. Temperature, humidity, vibration, electrical power supply, radiated energy and other influences are often controlled. Generally, it is the rate of change or instability that can be very detrimental.

Calibration technicians execute calibration work. In large organizations, the work is further divided into three groups:

Alternatively, the technicians can be divided by major discipline areas: physical, dimensional, electrical, microwave and so on. But the principles are the same regardless of the equipment. Metrology technicians perform investigation work in addition to calibrations. They also apply proven principles to known situations and evaluate unexpected or contradictory results. Metrologists are people who perform metrology work at and above the technician levels.

The metrology and calibration work is always accompanied by documentation. The documentation can be divided into two types; one related to the task and the other related the administrative program. Task documentation includes calibration procedures and the data collected. Administrative program documentation includes equipment identification data, calibration certificates, calibration time interval information and 'as-found' or 'out-of-tolerance' notification. Administrative programs provide standardization of the metrology and calibration work and make it possible to independently verify that the work was performed. Generally, the administrative program is specific to the organization performing the work and addresses customer requirements. General administrative program specifications created by industry groups, such as the ANS (ANSI) Z540 series may also be covered in the administrative program. Other specifications created by the US Food and Drug Administration, US Federal Aviation Administration or other agencies would supplement or replace ANS Z540 for work performed in their domains. Often administrative programs can be as complicated and detailed as the measurement work itself.
