IEC 63085-2021 pdf free download – Radiation protection instrumentation – System of spectral identification of liquids in transparent and semitransparent containers (Raman systems).
4 Requirements
4.1Structure and appearance
The connection ports of the Raman analyzer should be designed for easy installation andremoval of the test sample, the condition specified in 3.1.
4.2 Functions
4.2.1Alarm
The Raman analyzer should automatically provide warning in the form of acoustic and/orvisual signals when hazardous liquids are identified.
4.2.2Displayed data
a) The Raman analyzer shall display the identification result in a text or graphical form
including optional fields subject to 3.6.
b) The Raman analyzer shall provide an interface for recording an identification data
protocol.
4.2.3Recording and storage of identification data
a) Inspected substance identification data and alarm activation marks should be
automatically stored as a time-ordered sequence of data，including identification dataprotocol subject to 3.7. Users may have the option to disable automatic data logging.
b) Software shall be provided for search and retrieval of identification data.
c) ldentification data protocol subject to 3.7 shall be reliably protected in a secure, read-only mode with authorized access to stored data and spectra.
d) The system shall be capable of exporting protocol data (or protocol fragments) and identification results in commonly used non-proprietary text or graphical formats.
e) lt should be possible to access and transfer recorded spectral data to external data carriers in digital form.
4.2.4 Error diagnostics and self-verification
The system should have the functionality of error diagnostics and self-verification. Self-verification can be automatic or manual and should cover issues of the device calibration andapparatus functionality.This can be realized via internal calibrated light sources or based onan external etalon sample.
4.2.5Access control software
The Raman analyzer should have an option to verify the operator’s lD.Any unique digital orbiometric ID parameters can be used for verification of authorized operators.
4.3Performance
4.3.1 Testing conditions
4.3.1.1Environmental conditions
Except where otherwise specified，tests shall be carried out under the standard testconditions shown in the third column of Table 1.For tests performed outside the standard testconditions，the values of temperature，pressure and relative humidity shall be stated andappropriate corrections，if any，made to ensure the expected response under referenceconditions (column 2).All the tests mentioned in 4.3 shall be performed with the same systemoperating parameters. The values of any deviations should be reported. The referenceconditions are given in the second column of Table 1.
The values in Table 1 are intended for tests performed in temperate climates. In otherclimates actual test values shall be stated. Atmospheric pressure lower than 70 kPa isallowed at higher altitudes and shall be similarly recorded.
4.3.1 .2 Test apparatus
The key apparatus for substance identification tests is shown in Table 2.
4.3.2Time for single inspection4.3.2.1Requirements
Maximum permitted inspection time shall not exceed 10 s.
4.3.2.2Test method
The system shall successfully identify test sample 1 subject to ASTM E1840 – 96:2014;inspection time is subject to the requirements of 4.3.2.1(Figure A.1 of Annex A).
4.3.3 Requirements for minimum volume of liquid to be inspected
4.3.3.1Requirements
The Raman analyzer shall be capable of analyzing a liquid object with minimum volume of10 ml.
4.3.3.2Test method
Use test sample 2 for the minimum volume test. The test shall successfully identifycyclohexane by comparison to the reference spectrum given in ASTM E1840 -96;2014,inspection time is subject to the requirements of 4.3.2.1.
4.3.4Requirements for container wall thickness4.3.4.1Requirements
The Raman analyzer shall be capable of checking a liquid with a container wall thickness upto 10 mm.IEC 63085 pdf download.
