5. Akalangidwa ndi mayiko a EU, bungwe la certification lidzakhala limodzi ndi zoopsa ndi bizinesi, motero kuchepetsa chiopsezo cha bizinesi.

▍Chifukwa chiyani MCM?

● MCM ili ndi gulu laukadaulo lomwe lili ndi akatswiri opitilira 20 omwe amagwira ntchito yotsimikizira satifiketi ya CE ya batri, yomwe imapatsa makasitomala chidziwitso cha CE chachangu komanso cholondola komanso chaposachedwa;

● MCM imapereka mayankho osiyanasiyana a CE kuphatikizapo LVD, EMC, malangizo a batri, etc. kwa makasitomala;

● MCM yapereka mayeso opitilira 4000 batire CE padziko lonse lapansi mpaka lero.

Pa November 27, 2023, "Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) linatulutsidwa mwalamulo pa webusaiti ya United States."Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) likuvomereza zosinthidwa zomwe zinapangidwa ndi gawo la 11 la United Nations TDG ndi GHS Expert Committee pa "UN Manual of Tests and Criteria" (Chiv. 7) ndi Kusintha kwake 1 . Monga kuyesa kofunikira kwa kayendedwe ka chitetezo cha batri, "Buku la UN la Mayesero ndi Zofunikira" (Chiv. 8) yawonjezera gawo latsopano la 38.3.3.2 "Kuyesedwa kwa maselo a sodium ion ndi mabatire", ndipo panthawi imodzimodziyo anawonjezera zolemba zokhazokha zokhudzana ndi . mabatire a sodium-ion mu UN "Recommendation on Transport of Dangerous Goods" (TDG) Rev. 23: UN 3551 ndi UN 3522.
T.1: Kuyerekeza kokwera (selo ndi batri)
Maselo oyesera ndi mabatire adzasungidwa pa mphamvu ya 11.6 kPa kapena kuchepera kwa maola asanu ndi limodzi pa kutentha kozungulira (20±5℃) Maselo oyesera ndi mabatire ayenera kusungidwa kwa maola osachepera asanu ndi limodzi pa kutentha kwa mayeso ofanana ndi 72 ℃ ndi -40 ℃.Njirayi iyenera kubwerezedwa mpaka magawo 10 athunthu atha.
Maselo ndi mabatire amatetezedwa mwamphamvu ku nsanja ya makina ogwedezeka, ndi kugwedezeka kwake kukhala mawonekedwe a sinusoidal ndi kusesa kwa logarithmic pakati pa 7 Hz ndi 200 Hz, ndi matalikidwe a 0.8mm, kwa selo ndi batire yaying'ono imanyamula mathamangitsidwe apamwamba kwambiri. 8 gn, ndi batire lalikulu amanyamula mathamangitsidwe pazipita 2 gn. Selo yaing'ono: pazipita mathamangitsidwe 150 gn, pulse nthawi ya 6 milliseconds. Selo lalikulu: pazipita mathamangitsidwe 50 gn, pulse nthawi 11 milliseconds.
