GB/T 30117.4-2023Photobiological safety of lamps and lamp systems - Part 4: Measuring methods (English PDF)

Foreword

This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives

for Standardization - Part 1.Rules for the Structure and Drafting of Standardizing Documents.

This document is Part 4 of GB/T 30117 Photobiological Safety of Lamps and Lamp Systems.

GB/T 30117 has issued the following parts.

---Part 2.Guidance on Manufacturing Requirements Relating to Non-laser Optical

Radiation Safety;

---Part 3.Guidelines for the Safe Use of Intense Pulsed Light Source Equipment on

Humans;

---Part 4.Measuring Methods;

---Part 5.Image Projectors.

This document modifies and adopts IEC TR 62471-4.2022 Photobiological Safety of Lamps

and Lamp Systems - Part 4.Measuring Methods. The document type is adjusted from ISO's

technical report to the national standard of China.

In comparison with IEC TR 62471-4.2022, this document makes the following structural

adjustments.

---Appendix C corresponds to Appendix F in IEC TR 62471-4.2022;

---Appendix D corresponds to Appendix I in IEC TR 62471-4.2022;

---Appendix E corresponds to Appendix D in IEC TR 62471-4.2022;

---Appendix F corresponds to Appendix E in IEC TR 62471-4.2022;

---Appendix G corresponds to Appendix H in IEC TR 62471-4.2022;

---Appendix H corresponds to Appendix G in IEC TR 62471-4.2022;

---Appendix I corresponds to Appendix C in IEC TR 62471-4.2022.

The technical differences between this document and IEC TR 62471-4.2022 and the causes for

these differences are as follows.

---The normative reference GB/T 30117 (all parts) is used to replace IEC 62471 to facilitate

the application of this document;

---"for retinal thermal hazards, measure the radiance dose and / or peak radiance of the

pulse" is added to E.1, and "for retinal thermal hazards, measure the pulse width (1 µs

~ 0.25 s)" is added to E.2.The supplemented content is based on the requirements of

the International Commission on Non-Ionizing Radiation Protection (ICNIRP 2013)

for the assessment of retinal thermal hazards of pulsed light sources.

This document makes the following editorial modifications.

---A NOTE is added to Chapter 1;

---The abbreviation "HID" is deleted from 3.2, because this term does not appear in the

text;

---The NOTE below Table 1 is deleted;

---NOTE 2 is deleted from 4.7.4.3;

---A NOTE is added below Formula (3);

---Index numbers are used instead of text descriptions in all figures, and the description of

index numbers is supplemented;

---Symbol descriptions are added for some letter symbols in the figures;

---"Le" in Formula (D.2) is modified into "L", and "Phie" is modified into "Phi".

1 Scope

This document describes the radiometric and spectral radiometric measurement methods

required to determine the accessible optical radiation levels of lamps and lamp systems in

accordance with GB/T 30117 (all parts).

This document is intended for practical measurement by manufacturers, testing organizations,

safety personnel, and other relevant personnel, etc.

NOTE. this document involves both Level A and Level B assessments. Level A assessment is an

accurate measurement method that uses sophisticated spectral radiometric equipment to

measure accessible optical radiation and can be used in all situations. Level B assessment

uses common and simple instruments for measurement, which is only used for preliminary

screening and is not suitable for use in rigorous judgment and data reporting.
