GB 4943.1-2022标准要求下Ⅲ类打印机的安全防护

Safeguards for Class III Printers Under GB 4943.1-2022 Standard

由于此次GB 4943.1-2022标准的实施,一些打印机产品的设计不能满足现行标准的要求,本文通过解读GB 4943.1-2022标准要求下Ⅲ类打印机的能量源风险和安全防护。同时结合笔者工作中遇到的一些典型案例来分析这些能量源风险,特别是标准中新的和比较容易被忽视的能量源风险,针对这些能量源风险,提出行而有效安全防护方案。

Due to the implementation of the GB 4943.1-2022 standard,the design of some printers can not meet the requirements of the current standard.This paper interprets the energy source risk and Safeguards of Class III printers under the GB 4943.1-2022 standard.At the same time,combining with some typical cases in the author's work to analyze these energy source risks,especially the new or easy to be ignored energy source risks in the standard,aiming at these energy source risks,put forward the feasible and effective Safeguard.
