IEC 60335-2-24 ED. 8.0 B:2020适用范围

IEC 60335-2-24:2020涉及以下家用和类似用途的电器、制冷设备的安全；制冰机包括电机压缩机和制冰机，用于冷冻食品储存室；用于露营的制冷设备和制冰机，休闲旅行队和船只，单相电器额定电压不超过250V，其他电器额定电压不超过480 V，电池操作时为24 V直流。这些电器可以从电源、独立电池或从电源或独立电池操作。本标准还涉及家用冰淇淋电器的安全性，单相电器额定电压不超过250V，其他电器480V。它还涉及家用和类似用途的压缩式电器，这些设备使用易燃制冷剂。

与上一版本相比，本版的主要变化如下：

-将文本与IEC 60335-1及其修正案对齐；

-明确“家庭和类似用途”一词；

-更新电池操作电器供电端子的标记要求；

-介绍了使用跨临界制冷剂系统的设备要求；

-介绍了一种增强的弯曲试验；

-介绍了可接近玻璃面板的要求；

-澄清使用易燃制冷剂的电器的试验。

提请各国委员会注意，在公布新的、经修订或修订的IEC出版物后，设备制造商和测试组织可能需要过渡期，以根据新要求生产产品，并为进行新的或修订的测试配备设备。

IEC 60335-2-24:2020 deals with the safety of the following appliances, refrigerating appliances for household and similar use; ice-makers incorporating a motor-compressor and ice-makers intended to be used in frozen food storage compartments; refrigerating appliances and ice-makers for use in camping, touring caravans and boats for leisure purposes, their rated voltage being not more than 250 V for single-phase appliances and 480 V for other appliances and 24 V d.c for appliances when battery operated. These appliances may be operated from the mains, from a separate battery or operated either from the mains or from a separate battery. This standard also deals with the safety of ice-cream appliances intended for household use, their rated voltage being not more than 250 V for single phase appliances and 480 V for other appliances. It also deals with with compression-type appliances for household and similar use, which use flammable refrigerants.

The principal changes in this edition as compared with the previous edition are as follows:

- aligns the text with IEC 60335-1, and its amendments;

- clarifies the term "household and similar use";

- updates marking requirements for supply terminals of battery operated appliances;

- introduces requirements for appliances using transcritical refrigerant systems;

- introduces an enhanced flexing test;

- introduces requirements for accessible glass panels;

- clarifies tests for appliances using flammable refrigerants.

he attention of national Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselfs for conducting new or revised tests.

满足IEC 60335标准的测试仪器——QUV/uvc紫外老化测试箱

美国Q-LAB新款紫外线老化测试箱QUV/uvc满足IEC 60335标准要求。UV紫外线在紫外线杀菌照射（UVGI）中被广泛应用，UVGI是一种用于消除有害病毒和细菌的技术。这种短波高能量UVC紫外线也能降解它消毒的材料及外表。QUV/uvc紫外老化试验机使用uvc灯管产生254nm的短波紫外线，以测试材料的耐久性，防止因暴露在uvc紫外线下产生的光降解效应。QUV/uvc紫外老化试验机有多种安全功能，可防止杂散的uvc光线逸出；它不配备冷凝或喷淋功能。

UVC LAMPS 灯管

紫外线灯管产生254nm的超强短波紫外线，这远远低于太阳光的极限。这代表了用于表面消毒的最常见的UVC紫外线辐射。虽然紫外线能有效地杀死这些病原体，但紫外线也能引起塑料、涂料和织物的降解。UVC紫外灯管再现这种破坏性的辐照度，以评估材料暴露在UVC紫外线下的耐久性。
