German term

Rückführung

German to English Tech/Engineering Metrology calibration of test equipment
It is said that test equipment used for calibrating certain measurement devices is periodically sent to outside laboratories for "Rückführung auf nationale Normale". I am tempted to call this "external recalibration based on national standards".

Discussion

Johannes Gleim Sep 9, 2015:
calibration is what I did for 16 years. I was part of my activities as approval engineer. I had to monitor the calibration records for all instruments used in the laboratories and the factory. Each instrument was calibrated regularly and certified with a calibration certificate stating " Der Kalibrierschein dokumentiert die Rückführung auf nationale Normale.
The calibration certificate documents traceability to the national standards."
or similar.

My subsequent activities as factory inspector (7 years) on behalf of ETL and UL comprised travelling throughout Europe. During verification of QM systems like ISO 9000 and other, I always checked valid calibration of instruments and whether the certificates bears the mention "The calibration certificate documents traceability to the national standards", what is there worldwide standardized term.

Please note that literal translation is therefore not appropriate.
Leo, for ex. translates "traceability" by "Rückverfolgbarkeit, Nachverfolgbarkeit, Rückführbarkeit" and "Rückführung" by "feedback, return". Similar results with other online dictionaries.

traceability to the national standards

In Kalibrierscheinen wird „Rückführung auf nationale Normale“ regelmäßig mit „traceability to the national standards“ übersetzt, obwohl „traceability“ eigentlich „Rückverfolgbarkeit“ bedeutet.

en traceability
property of the result of a measurement or of the value of a standard such that it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated uncertainties
Note 1 – The concept is often expressed by the adjective traceable.
Note 2 – The unbroken chain of comparisons is called a traceability chain.
Note 3 – In French, the way in which the relationship with the standards is determined is called "raccordement aux étalons".

Metrology is a very broad field and may be divided into three basic activities, though there is considerable overlap between the activities:[3][4]
• Definition of internationally accepted units of measurement.
• Realisation of these units of measurement in practice
• Application of chains of traceability linking measurements made in practice to reference standards.
:
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; Physikalisch-Technische Bundesanstalt; etc.
:
Every state maintains its own weights and measures functionality with traceability to the national standards maintained by NIST.
https://en.wikipedia.org/wiki/Metrology

Below a short survey for the term “traceability to the national standards” (12.400 Ghits, and 13.900 Ghits for "traceability to national standards", randomly collected). Most articles are from native speakers.

1.1 Legal requirements for traceability
State laws require State primary standards to maintain traceability to the national standards in the possession of the National Institute of Standards and Technology.
:
7.1 Accreditation systems for legal metrology, calibration and testing laboratories. Traceability to national, regional, international or foreign measurement standards
http://www.mmasa.com/anftp/USA.htm

What is Traceability?
Traceability can be defined as an unbroken record of documentation ("documentation traceability") or an unbroken chain of measurements and associated uncertainties ("metrological traceability"). As used here, the word "traceability" always means "metrological traceability."
http://www.nist.gov/pml/mercury_traceability.cfm
(NIST, USA, 2011)

The most common way to relate industrial calibration measurements to the national standards is to have the local reference standards calibrated in a way that provides traceability to the national standards.
(NIST, USA, 1983)

The term "traceability to NBS" or "traceability to the national standards" is being used more frequently. Several examples include: Federal and state regulations, voluntary standards such as those published by the American National Standards Institute ….
https://books.google.de/books?id=p9naKH-WVZ4C&pg=PA1&lpg=PA1...
(U.S. Department of Commerce/National Bureau of Standards, 1982)

The Food and Drug Administration maintains an X-ray Calibration Facility to calibrate instruments that inspectors use to verify compliance with the Radiation Control Health and Safety Act (RCHSA) and the Mammography Quality Standards Act (MQSA). To maintain a strong traceability to the national standards and to provide creditability to the calibrations, the Calibration Laboratory is accredited by NVLAP.
http://hps.org/meetings/midyear/abstract271.html
(USA)

Metrologists are required to complete the traceability chain by stating the uncertainty of their measurements with respect to a National Metrology Institute (NMI). The NMI is required to show traceability to the International System (SI) of units maintained by the Bureau International des Poids et Mesures (BIPM). Traceability is often a legal or contractual requirement, and its importance to quality control systems cannot be overstated. The International Organization for Standardization (ISO) Guide 25 lists the requirements for competence of calibration and testing laboratories. Section 9.2 of Guide 25 states:
The overall programme of calibration and/or verification and validation of equipment shall be designed and operated so as to ensure that, wherever applicable, measurements made by the laboratory are traceable to national standards of measurement, where available. Calibration certificates shall wherever applicable indicate the traceability to national standards of measurement and shall provide the measurement results and associated uncertainty of measurement and/or a statement of compliance with an identified metrological specification.

(a) Level 1: A calibration carried out by a laboratory accredited by UKAS for the measurements concerned and for which a UKAS calibration certificate is issued.
Certificates from other calibration bodies may be acceptable provided that full traceability to national standards is demonstrated.

Traceability
Metrological traceability means that a measurement result can be linked to the SI units through an unbroken chain of calibrations and that the measurement uncertainty for each step of the chain must be known.
In the area of legal metrology the measurement systems in industry are kept under regular surveillance by Justervesenets verification offices which have traceability of their instruments to the national standards. The companies obtain a verification that their instruments give results within accepted tolerances.
In the voluntary area industry and service-providing companies and authorities must establish traceability to the national standards by calibrating their standards and instruments at Justervesenet´s National Metrology Laboratory or at an accredited calibration laboratory. The calibration is documented by a calibration certificate, giving the calibration value (deviation from correct value) and the associated measurement uncertainty.

There are 4 regional laboratories, ten state level laboratories and 2 high precision calibration centre's at Delhi and Bangaluru. The STQC laboratories are equipped with the state of the art calibrating facilities. These laboratories serve as support hierarchy in establishing traceability to the National Standards through their calibration services to electronic & allied industries for electro technical and non-electrical parameters

Section 10 of the National Measurement Act establishes the requirement for legal traceability to the national standards of measurement. Legal traceability is demonstrated through Regulation 80 Certificates issued by Verifying Authorities. CSIRO and its agents through their calibration services provide metrological traceability to the national standards of measurements. Where legal traceability is required a Regulation 80 Certificate should be issued.

7.2 The certification bodies require the certified factories to have traceability to the national standards. Whenever certification is carried out, the metrology service is called upon for assistance, and the factories make use of instrument regulations developed by CSBTS.

The point is that "traceability" is differently translated by DKD and IEC. Do you have doubts on the term? Nearly all calibration institutes in Germany adopted the DKD wordings. So nothing is bad. Please allow me to propose based on own research!

The operative/relevant part of the above definition is
Rückführung --> ein Vorgang, durch den (etwas) mit einem nationalen Normal verglichen werden kann
Accordingly,
"for Rückführung auf nationale Normale" --> for comparison with national standards

Oh, ok. After looking up http://www.thefreedictionary.com/calibrate calibrate = to check, adjust, or determine by comparison with a standard, I see your point. Thanks.
neutral Kim Metzger : The final measurement will have traceability to NIST standards if the following conditions are met: 1. An unbroken chain of measurements back to NIST standards is maintained.http://www.nist.gov/pml/mercury_traceability.cfm
