Management Centre or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other language made by translation
under the responsibility of a CENELEC member into its own language and notified to the CEN-CENELEC Management Centre has the
same status as the official versions.

Endorsement notice
The text of the International Standard IEC 60846-1:2009 was approved by CENELEC as a European
Standard with agreed common modifications.
In the official version, for Bibliography, the following notes have to be added for the standards
indicated:
IEC 60325:2002 NOTE  Harmonized as EN 60325:2004 (modified).
IEC 61005:2003 NOTE  Harmonized as EN 61005:2004 (modified).
COMMON MODIFICATIONS
All over the document
Replace “1,5 MeV” with “1,33 MeV”.
3 Terms and definitions
In the note of 3.19, replace “Tables 5 to 8” with “Tables 5 to 9”.
4 Units and list of symbols
In Table 2, delete the row starting with t .
min
5 General characteristics of ambient and directional dose equivalent (rate)
meters
In 5.7, replace “Tables 4 to 8” with “Tables 5 to 9”.
8 Radiation performance requirements and tests
In 8.9.2.2, replace the second paragraph by the following:
The initial and final dose equivalent rates shall differ by a factor of 10 or more up to the factor for the
change from background dose rate to the maximum dose rate of the rated range. The measurements
shall be carried out for both an increase and a decrease in the dose equivalent rate by this factor. The
initial or the final dose equivalent rate shall be the background dose rate.
10 Mechanical characteristics of directional and ambient dose equivalent (rate)
meters
Add the following new subclause.
10.Z1 Drop test during operation
10.Z1.1 Requirements
Portable dose equivalent (rate) meters shall be able to withstand without damage, a drop from a
height of 0,3 m onto a hard steel or concrete surface.

10.Z1.2 Test method
The dose equivalent (rate) meter shall withstand at least one single drop from 0,3 m to each surface of
dose equivalent (rate) meter so that the unit is still operable after the drop. The test may be performed
either with one or more test units in such a way that one drop onto each surface of the dose equivalent
(rate) meter is tested. The instrument passes the test if the instrument response does not deviate after
the 6 drop tests from the original response by more than - 17 % to + 25 %. The drop can make the
instrument switch off but the user shall be able to switch the unit back on. The physical condition of the
instrument shall not be affected by these drops (for example solder joints shall hold, nuts and bolts
shall not come loose).
11 Environmental characteristics, performance requirements and tests
In 11.4.2, replace the last sentence by “The differences shall be within - 9 % to + 11 %”.
Table 9 – Mechanical performance under test conditions
Add the following at the end of Table 9.
Drop during operation 0,3 m 6 drops from a given height onto 10.Z1
steel or concrete surface
Annexes
Add the following new annex.
