4 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
4.1
primary standard
set of reference cards established by Physikalisch-Technische Bundesanstalt (PTB) and maintained by PTB, Q-Card, and WGI secretariat that represent the values of UR and Ig designated RM 7811-2
4.2
secondary standard
reference card designated RM 7811-2 that is related to the primary standard as stated in the calibration certificate supplied with each card
Note ito entry: Secondary standards can be ordered from Q-Card, 301 Reagan St., Sunbury, PA 17801, USA. The source of secondary standards will be maintained at least until 2018,
4.3
unused unencoded savingsbook
savingsbook possessing all the components required for its intended purpose, which has not been subjected to any personalization or testing operation, and which has been stored in a clean environment with no more than a 48 h exposure to daylight at temperatures between 5 °C and 30 °C and a humidity between 10 % and 90 % without experiencing thermal shock
4.4
unused encoded savingsbook
unused unencodedsavingsbook (4.3) that has only been encoded with all the data required for its intended purpose (e.g. magnetic encoding, electronic encoding)
4.5
returned savingsbook
unused encoded savingsbook (4A) after it has been issued to the savingsbook holder and returned for the purpose of testing
4.6
flux transition
location of the greatest rate of change with distance of the magnetisation
4.7
reference current
minimum recorded current amplitude under the given test conditions that causes, on the reference card, a readback signal amplitude equal to 80 % of the reference signal amplitude, UR, at a density of 8 flux transitions per millimetre (200 flux transitions per inch) as shown in Figurc4
4.8
reference flux level
FR
flux level in the test head that corresponds to the reference current, IR.BS ISO/IEC 8484 pdf download.
