阴极射线管的机械安全SUL 619651范围本国际标准适用于阴极射线管和阴极射线管组件（以下简称CRT），这些阴极射线管和阴极射线管组件拟用作仪器中的部件，并对内爆的影响具有整体保护。这些要求适用于拟用于电气和电子测量和测试设备、信息技术设备、医疗设备、电话设备、电视设备和其他类似电子设备的CRT。本标准仅适用于CRT表面构成设备外壳一部分的CRT。本试验方法不适用于受单独安全屏保护的CRT。 本标准涵盖的阴极射线管拟安装在一个外壳中，该外壳设计用于在正常操作条件下保护阴极射线管后部免受机械或其他损坏，并在发生内爆时保护用户免受从阴极射线管表面向后排出的颗粒物的伤害。本标准包含76 mm及以上对角线CRT的要求，该CRT包含内爆保护系统，可防止颗粒向前喷射到面部以外的危险。没有针对从其他方向排出的颗粒的预期保护。通过将CRT置于本标准第8条（大CRT）、第9条（小CRT）和第10条（带保护膜的CRT）中给出的测试程序和标准中来测试合规性。 第3条给出了大型和小型CRT的定义。注:本组要求取代了IEC 60065（第18条）中所述的阴极射线管（CRT）机械安全的现行要求，并将对其进行相应修改。

Mechanical Safety for Cathode Ray TubesUL 619651 ScopeThis International Standard is applicable to cathode ray tubes and cathode ray tube assemblies (hereinafter referred to as CRTs) which are intended for use as components in apparatus and which have integral protection with respect to the effects of implosion.These requirements apply to CRTs intended for use in apparatus including electrical and electronic measuring and testing equipment, information technology equipment, medical equipment, telephone equipment, television equipment and other similar electronic apparatus.This standard is intended to apply only to those CRTs in which the face of the CRT forms part of the enclosure for the apparatus. The test methods do not apply to CRTs which are protected by separate safety screens.A CRT covered by this standard is intended to be installed in an enclosure designed both to protect the rear of the CRT against mechanical or other damage under normal conditions of operation and to protect the user against particles expelled in a backwards direction from the CRT face in the event of implosion.This standard contains requirements for CRTs of 76 mm diagonal and larger that incorporate implosion protection systems providing protection against the hazards of particles expelled forwards beyond the face. There is no intended protection against particles expelled in other directions.Compliance is tested by subjecting CRTs to the test procedures and criteria which are given in clauses 8 (large CRTs), 9 (small CRTs) and 10 (CRTs with protective film) of this standard. The definitions of large and small CRTs are given in Clause 3.NOTE This set of requirements replaces the current requirements for the mechanical safety of cathode ray tubes (CRTs) as described in IEC 60065 (clause 18), which will be modified accordingly.
