Isigaba somthetho 1(Ububanzi) Ukuhunyushwa kwesigaba sokuqala

Isigaba sokuqala sobubanzi singezansi:
IEC 60335-1:2020 okuqukethwe:
Leli Zinga Lamazwe Ngamazwe liphathelene nokuphepha kwezinto zikagesi zasendlini nezinye izinjongo ezifanayo, amandla ogesi azo alinganiselwe angabi ngaphezu kuka-250 V ezintweni zikagesi zesigaba esisodwa kanye nama-480 V kwezinye izinto ezihlanganisa izinto zamanje eziqondile (DC) ezihlinzekwa ngebhethri kanye nezinto ezisebenza ngebhethri. .
IEC 60335-1:2010+A1:2013+A2:2016 Inguqulo 5.2 kuhlanganise nenguqulo 5.1:
Leli Zinga Lamazwe Ngamazwe liphathelene nokuphepha kwezinto zikagesi zasendlini nezinye izinjongo ezifanayo, ugesi wazo olinganiselwe ungekho ngaphezu kuka-250 V ezintweni zikagesi zesigaba esisodwa kanye no-480 V kwezinye izinto zikagesi.
Iphuzu elingukhiye 2: Leli zinga liphathelene nokuphepha komkhiqizo, futhi ukuphepha akuhlobene, njengokusebenza kahle kwamandla, i-EMC, ukusebenza, njll. akukho kububanzi baleli zinga.

Inhloso efanayo, ngicabanga ukuthi umbandela oyinhloko iqembu labantu abasebenzisa umshini. Abantu abasebenzisa umshini ngokuvamile kungabantu abangenalwazi okungenzeka bengenalo ulwazi oluyisisekelo lokuvimbela ukushaqeka kukagesi. Isibonelo, imishini yokuthengisa esetshenziswa ezitolo ezinkulu. Ngakolunye uhlangothi, imishini yezentengiselwano ka-ayisikhilimu esetshenziswa ezindaweni zokudlela ezisheshayo iyisimo sokusetshenziswa kwezentengiso. Singathola ulwazi mayelana nemikhiqizo esebenzayo ngokusekelwe egameni lengxenye 2.

Ezinguqulo zangaphambilini zezinga, bekunokugxila okuncane nokukhulunywa ngakho ngemikhiqizo enamandla e-DC, naleyo esebenzisa amandla ebhethri. Njengoba sesishilo, izindinganiso zivame ukusala ngemuva kwemikhiqizo nobuchwepheshe. Ezinguqulweni zangaphambilini zezinga, izidingo bezigxile kakhulu emikhiqizweni esebenza ngamandla e-AC; njengoba ubuchwepheshe buye bashintsha futhi imikhiqizo eminingi esebenza ngebhethri kanye nemikhiqizo esebenza ngamandla e-DC yakhiwe futhi yethulwa emakethe, izinga libuyekeziwe ukuze kucatshangelwe lezi zidingo. Isibonelo esijwayelekile isigatshana 12 – Ukushajwa kwamabhethri e-metal-ion.

Key point 3: This standard is concerned with “household and similar purpose” appliances. Household means domestic, and similar purpose could mean using in farm, light industry, hotel, office, shopping malls, convenience stores.
Similar purpose, I think the main criterion is the group of people who use the appliance. People who use the appliance are usually inexperienced people who may not have the most basic awareness of preventing electric shock. For example, vending machines used in shopping malls. On the other hand, commercial ice cream machines used in fast food restaurants is a commercial use condition . We can obtain information about applicable products based on the name of part 2.

If a new product cannot find a corresponding part 2 based on the name and the requirement in part 2, and we determine that it is a similar purpose or household appliance, only part 1 can be used for evaluation. For example, Air Oxygen Concentrator for domestic not for medical use.

In previous versions of the standard, there was relatively little focus and mention of DC-powered products, and those using battery power. As we mentioned, standards often lag behind products and technologies. In previous versions of the standard, the requirements were more focused on AC-powered products; as technology has evolved and more battery-powered products and DC-powered products have been designed and introduced to the market, the standard has been updated to take these requirements into account. A typical example is clause 12 – Charging of metal-ion batteries.
