GB/Z 142-2025Germicidal UV-C irradiation products safety guidelines (English PDF)

Foreword

This document is a report-type guidance technical document.

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document modifies and adopts IEC PAS 63313:2021 "Position Statement on UV-C Irradiation for Germicidal Purification - Guidelines for UV-C Safety", document type.

The standard has been changed from a publicly available IEC specification to a national standardization guiding technical document of my country.

This document has undergone the following structural adjustments compared to IEC PAS63313:2021.

---Chapter 1 of IEC PAS63313:2021 has been deleted;

---Chapter 1 corresponds to Chapter 2 of IEC PAS 63313:2021;

---Added Chapter 2, Normative References;

---Chapter 3 corresponds to Chapter 7 of IEC PAS 63313:2021;

---Chapter 4 corresponds to Chapter 3 of IEC PAS 63313:2021;

---Chapter 5 corresponds to Chapter 4 of IEC PAS 63313:2021;

---Chapter 6 corresponds to Chapter 5 of IEC PAS 63313:2021;

---Chapter 6 of IEC PAS63313:2021 has been deleted;

---Appendix A corresponds to Appendix B of IEC PAS 63313:2021;

---Appendix A of IEC PAS63313:2021 has been deleted.

The technical differences between this document and IEC PAS63313:2021, and the reasons therefor, are as follows.

---The scope has been expanded with a statement of usage limits (see Chapter 1) to suit my country's national conditions;

---The normative reference GB/T 21092 [see 6.1a)] has been added to adapt to my country's national conditions;

---Table 3, "Other alternative ozone exposure level limits" (see Chapter 4 of IEC PAS 63313:2021), has been deleted to accommodate...

my country's national conditions;

The terms "enclosed enclosure," "controlled area," "irradiance (at a point on the surface)," "partially open enclosure," and "personal protective equipment" have been removed.

"Human presence detection system" and "time protection" (see Chapter 7 of IEC PAS 63313:2021) are needed to adapt to my country's national conditions.

The following editorial changes have been made to this document.

---To align with existing standards, the standard's name has been changed to "Safety Guidelines for UV-C Radiation Products for Sterilization";

---The pending sections in Chapters 3 and 4 have been deleted;

---Adjust the wording of the suspended section in Chapter 5 and move it to the end of section 6.2;

---References have been added.
