1.1 This practice covers photomultiplier properties that are essential to their judicious selection and use in emission and absorption spectrometry. Descriptions of these properties can be found in the following sections:

  Section Structural Features 4  General 4.1  External Structure 4.2  Internal Structure 4.3 Electrical Properties 5  General 5.1  Optical-Electronic Characteristics of the Photocathode 5.2  Current Amplification 5.3  Signal Nature 5.4  Dark Current 5.5  Noise Nature 5.6  Photomultiplier as a Component in an Electrical Circuit 5.7 Precautions and Problems 6  General 6.1  Fatigue and Hysteresis Effects 6.2  Illumination of Photocathode 6.3  Gas Leakage 6.4 Recommendations on Important Selection Criteria 7
1.2 Radiation in the frequency range common to analytical emission and absorption spectrometry is detected by photomultipliers presently to the exclusion of most other transducers. Detection limits, analytical sensitivity, and accuracy depend on the characteristics of these current-amplifying detectors as well as other factors in the system.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
