英文名:Household and similar electrical appliances - Safety - Part 2-24: Particular requirements for refrigerating appliances, ice-cream appliances and ice makers
IEC 60335-2-24:2020涉及以下家用和類似用途的電器、制冷設備的安全;制冰機包括電機壓縮機和制冰機,用于冷凍食品儲存室;用于露營的制冷設備和制冰機,休閑旅行隊和船只,單相電器額定電壓不超過250V,其他電器額定電壓不超過480 V,電池操作時為24 V直流。這些電器可以從電源、獨立電池或從電源或獨立電池操作。本標準還涉及家用冰淇淋電器的安全性,單相電器額定電壓不超過250V,其他電器480V。它還涉及家用和類似用途的壓縮式電器,這些設備使用易燃制冷劑。
與上一版本相比,本版的主要變化如下:
-將文本與IEC 60335-1及其修正案對齊;
-明確“家庭和類似用途”一詞;
-更新電池操作電器供電端子的標記要求;
-介紹了使用跨臨界制冷劑系統(tǒng)的設備要求;
-介紹了一種增強的彎曲試驗;
-介紹了可接近玻璃面板的要求;
-澄清使用易燃制冷劑的電器的試驗。
提請各國委員會注意,在公布新的、經修訂或修訂的IEC出版物后,設備制造商和測試組織可能需要過渡期,以根據新要求生產產品,并為進行新的或修訂的測試配備設備。
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.
美國Q-LAB新款紫外線老化測試箱QUV/uvc滿足IEC 60335標準要求。UV紫外線在紫外線殺菌照射(UVGI)中被廣泛應用,UVGI是一種用于消除有害病毒和細菌的技術。這種短波高能量UVC紫外線也能降解它消毒的材料及外表。QUV/uvc紫外老化試驗機使用uvc燈管產生254nm的短波紫外線,以測試材料的耐久性,防止因暴露在uvc紫外線下產生的光降解效應。QUV/uvc紫外老化試驗機有多種安全功能,可防止雜散的uvc光線逸出;它不配備冷凝或噴淋功能。
UVC LAMPS 燈管
紫外線燈管產生254nm的超強短波紫外線,這遠遠低于太陽光的極限。這代表了用于表面消毒的最常見的UVC紫外線輻射。雖然紫外線能有效地殺死這些病原體,但紫外線也能引起塑料、涂料和織物的降解。UVC紫外燈管再現這種破壞性的輻照度,以評估材料暴露在UVC紫外線下的耐久性。
