INTRODUCTION
This document establishes standard test methods and objects for evaluating the capabilities
of Raman systems used for the spectral identification of liquids and liquids mixtures. The main
focus is made on testing the functionality of the equipment (Raman analyzer); the reliability of
identification result for liquids in containers with different light transmittance properties and
stability of the equipment performance under various environmental conditions. The design of
the optical scheme of the Raman analyzer, geometric and mass characteristics are not
discussed and left to the discretion of the manufacturer. This document does not specify the
circumstances and purposes of the inspection of liquids, the methods of detection of the
container, and also the safety techniques for handling unknown liquids. Hence, the imposed
requirements for the functionality of the Raman analyzer are equally suitable for its use in the
fields of security, analysis of pharmaceutical solutions and other liquid chemicals. Annex A
provides Raman scattering spectra of test samples, referred to in the test methods.

RADIATION PROTECTION INSTRUMENTATION –
SYSTEM OF SPECTRAL IDENTIFICATION OF LIQUIDS IN TRANSPARENT
AND SEMITRANSPARENT CONTAINERS (RAMAN SYSTEMS)

1 Scope
This document provides technical performance requirements, testing methods, requirements
for operational performance and accompanying documents, packaging, transportation and
storage conditions for the system of spectral identification of liquids in transparent and
semitransparent containers (hereinafter referred to as “system”), based on the method of
inelastic (Raman) light scattering by molecules.
This document applies both to stationary and hand-held systems; geometric and mass
parameters are not concerned in the tests. This document is applicable to substance
identification testing criteria as well as verification, approval and operating criteria of the
system. Since this document considers only the functionality of Raman analyzers and their
ability to identify single- or multicomponent fluids, it is equally suitable for verifying the Raman
analyzers assigned to security screening of threats, inspection of medical solutions, liquid
chemicals, etc.

4.3.8 Selectivity of substance identification
4.3.8.1 General
This tests the ability of a system to identify chemical substances, including mixed liquid
solutions.
4.3.8.2 Requirements
When analyzing chemical compounds, the identification data shall contain common names of
the compounds and/or synonyms and chemically related compounds. In the case of analysis
of binary solutions (see e.g. Figure A.4 and Figure A.5 of Annex A), identification of both
components shall be achieved. In the case of the ternary solution (see e.g. Figure A.5 of
Annex A), it is only required that any, all, or no components identified are so reported. The
spectra of binary or ternary solutions should not be stored in the spectral library of the system
prior to the test.
4.3.8.3 Test method
Analyze test sample 4. Both components – water and ethanol – shall be successfully
identified by the system under test; inspection time is subject to the requirements of 4.3.2.1.
Analyze test sample 5. The two components – methanol and ethanol – shall be successfully
identified by the system under test; inspection time is subject to the requirements of 4.3.2.1.
Analyze test sample 6. For the ternary compound, the requirement is that the three
components – methanol, ethanol and isopropanol – shall each be reported as identified by the
system under test or not; inspection time is subject to the requirements of 4.3.2.1. The
requirement is to report only.
4.4 Laser safety
4.4.1 General
Predetermined security measures are required for the Raman analyzer, depending on the
laser class to which it is assigned by the manufacturer. This applies to the visual and audible
indication of the status of the emitter, the presence of radiation blocking, protective casing
and other devices that protect the operator and bystanders from harmful exposure to laser

radiation.
4.4.2 Depending on its declared class of laser, the Raman analyzer shall meet the safety
requirements prescribed in IEC 60825-4:2006.
4.5 Electrical safety
4.5.1 Main power connection
4.5.1.1 Requirements
If operated using AC mains supply, the input voltage and frequency shall correspond to the
input parameters of the low-voltage power supply unit of the Raman analyzer. The input
parameters of the low-voltage power supply of the Raman analyzer shall be compatible with
the parameters of the available ac mains supply (subject to the requirements of
IEC 60038:2009).
4.5.1.2 Test method
Check that the permissible voltage and frequency range indicated on the low-voltage power
supply unit corresponds to the parameters of the available ac mains supply. Plug the Raman
analyzer into an outlet using a low-voltage power supply. Perform 4.3.2.2 and ensure normal
system operation.
– 16 – IEC 63085:2021 © IEC 2021
4.5.2 Stability at mains power supply
4.5.2.1 Requirements
If operated using AC mains supply, the Raman analyzer shall operate normally when the
supply voltage is between 85 % and 110 % of voltage rating and in the range of ± 3 Hz of
nominal frequency.
4.5.2.2 Test method
The Raman analyzer shall operate normally while being tested for 15 min at each of three
voltage levels, namely, AC voltage of 85 % of nominal value, the nominal value, and 110 % of
nominal value, respectively. A single test procedure mentioned in 4.3.2.2 shall be successfully
completed after 15 min of powering the instrument at each voltage level.
4.5.3 Battery connection
4.5.3.1 General
This subclause applies to systems that are battery powered.
4.5.3.2 Requirements
The Raman analyzer shall be suitably protected against the incorrect connection of the
battery.
4.5.3.3 Test method
The compliance to this requirement can be verified by observation or by test disconnection
and reconnection of the battery.
4.5.4 Stability to battery charge level
4.5.4.1 General
This subclause applies to the systems that are battery powered.
4.5.4.2 Requirements
In the case of battery power, the Raman analyzer should have a low-battery indication,
notifying that correct operation is no longer guaranteed. When a low-battery indication is
absent, the device should ensure normal operation.
4.5.4.3 Test method
By visual inspection of the Raman analyzer ensure that the low battery indication is present
on the device exterior. Check the performance of the system, powered from the battery, at the
charge level higher than the point of low battery indication. The system shall perform correct
identification of 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). Perform several tests more than once
every 10 min and confirm that the Raman analyzer gives correct identifications (in terms of
the substance ID) until the point at which a low battery indication is given.
4.6 Mechanical stability
4.6.1 General
This subclause applies to the systems that are free standing.

4.6.2 Requirements
The Raman analyzer should be physically stable when it is tilted up to 10° from its normal
position.
4.6.3 Test method
Place the Raman analyzer on a slope at 10° to the horizontal. The Raman analyzer should not
be overturned. Repeat for rotations of the system about a vertical axis by 90°.
4.7 Environmental requirements
4.7.1 Environmental suitability test
The system functionality shall be demonstrated before, during, and after applying standard
ambient testing. See Table 4 for environmental suitability tests and requirements.
