BS IEC 63085:2021 pdf download – Radiation protection instrumentation – System of spectral identification of liquids in transparent and semitransparent containers (Raman systems).
3.6 identification result data including the common name of the inspected and identified liquid substance, CAS Register number (optional), molecular formula (optional), structural formula (optional) and the recognition reliability factor (optional) Note 1 to entry: In the event of the identification of several substances, the identification result should include the aforementioned records for every identified substance. 3.7 identification data protocol data including time and date, Raman analyzer Identification Number (Raman analyzer ID), Operator ID (optional), the identification result, and digital representation of measured and corresponding reference Raman spectra 3.8 test liquid liquid used for testing system performance 3.9 test sample combination of a test container subject to 3.1 and a test liquid subject to 3.8 4 Requirements 4.1 Structure and appearance The connection ports of the Raman analyzer should be designed for easy installation and removal of the test sample, the condition specified in 3.1 . 4.2 Functions 4.2.1 Alarm The Raman analyzer should automatically provide warning in the form of acoustic and/or visual signals when hazardous liquids are identified. 4.2.2 Displayed 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. 4.2.3 Recording 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 data protocol 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) Identification data protocol subject to 3.7 shall be reliably protected in a secure, read-only mode with authorized access to stored data and spectra.
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 and apparatus functionality. This can be realized via internal calibrated light sources or based on an external etalon sample. 4.2.5 Access control software The Raman analyzer should have an option to verify the operator’s ID. Any unique digital or biometric ID parameters can be used for verification of authorized operators. 4.3 Performance 4.3.1 Testing conditions 4.3.1 .1 Environmental conditions Except where otherwise specified, tests shall be carried out under the standard test conditions shown in the third column of Table 1 . For tests performed outside the standard test conditions, the values of temperature, pressure and relative humidity shall be stated and appropriate corrections, if any, made to ensure the expected response under reference conditions (column 2). All the tests mentioned in 4.3 shall be performed with the same system operating parameters. The values of any deviations should be reported. The reference conditions are given in the second column of Table 1 . The values in Table 1 are intended for tests performed in temperate climates. In other climates actual test values shall be stated. Atmospheric pressure lower than 70 kPa is allowed at higher altitudes and shall be similarly recorded.
4.3.2 Time for single inspection Requirements Maximum permitted inspection time shall not exceed 1 0 s. Test method The system shall successfully identify test sample 1 subject to ASTM E1 840 – 96:201 4; inspection time is subject to the requirements of (Figure A.1 of Annex A). 4.3.3 Requirements for minimum volume of liquid to be inspected Requirements The Raman analyzer shall be capable of analyzing a liquid object with minimum volume of 1 0 ml. Test method Use test sample 2 for the minimum volume test. The test shall successfully identify cyclohexane by comparison to the reference spectrum given in ASTM E1 840 – 96:201 4, inspection time is subject to the requirements of . 4.3.4 Requirements for container wall thickness Requirements The Raman analyzer shall be capable of checking a liquid with a container wall thickness up to 1 0 mm.
