European foreword
This document (EN 2004-7:2017) has been prepared by the Aerospace and Defence Industries
Association of Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this European
Standard has received the approval of the National Associations and the Official Services of the member
countries of ASD, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2018, and conflicting national standards shall
be withdrawn at the latest by February 2018.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France,
Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands,
Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and
the United Kingdom.
1 Scope
This European Standard defines different types of electrical conductivity reference blocks, to be used for
the calibration of eddy current conductivity measuring equipment, their method of production and
calibration.
It is to be used in conjunction with EN 2004-1.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
EN 2004-1, Aerospace series - Test methods for aluminium and aluminium alloy products - Part 1:
Determination of electrical conductivity of wrought aluminium alloys
ISO 10012-1, Quality assurance requirements for measuring equipment - Part 1: Metrological confirmation
system for measuring equipment
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
master reference standards
a set of electrical conductivity reference standards, held by a National Standards Laboratory or an
Accredited Laboratory and traceable to electrical reference standards
Note 1 to entry: This set is maintained as the reference standard against which all the corresponding secondary
reference blocks shall be calibrated.
3.2
secondary reference blocks
sets of electrical conductivity reference blocks calibrated by a National Standards Laboratory or an
Accredited Laboratory against its master reference standards using eddy current conductivity measuring
equipment. Individual companies or organisations may hold sets of secondary reference blocks
Note 1 to entry: These blocks are the means by which traceability to the master reference standards is
maintained.
3.3
operating reference blocks
sets of electrical conductivity reference blocks prepared and calibrated by competent personnel against
secondary reference blocks using eddy current conductivity measuring equipment
Note 1 to entry: The operating reference blocks are used for routine instrument calibration.
