▍Kodi WERCSmart REGISTRATION ndi chiyani?

WERCSmart ndiye chidule cha World Environmental Regulatory Compliance Standard.

WERCSmart ndi kampani yolembetsa zolembera zopangidwa ndi kampani yaku US yotchedwa The Wercs. Cholinga chake ndi kupereka nsanja yoyang'anira chitetezo chazinthu m'masitolo akuluakulu ku US ndi Canada, ndikupangitsa kugula zinthu kukhala kosavuta. Pakugulitsa, kunyamula, kusunga ndi kutaya zinthu pakati pa ogulitsa ndi omwe adalembetsa, zinthu zidzakumana ndi zovuta zambiri kuchokera ku federal, mayiko kapena malamulo amderali. Nthawi zambiri, Safety Data Sheets (SDSs) woperekedwa pamodzi ndi zinthuzo sakhala ndi data yokwanira yomwe imawonetsa kutsata malamulo ndi malangizo. Pomwe WERCSmart imasintha zinthu zomwe zimagwirizana ndi malamulo ndi malamulo.

▍Kuchuluka kwazinthu zolembetsa

Ogulitsa amasankha magawo olembetsa kwa aliyense wogulitsa. Magulu otsatirawa adzalembetsedwa kuti agwiritsidwe ntchito. Komabe, mndandanda womwe uli pansipa ndiwosakwanira, chifukwa chake kutsimikizira zolembetsa ndi ogula anu kumaperekedwa.

◆Zinthu Zonse Zokhala ndi Chemical

◆ OTC Product and Nutritional Supplements

◆Zinthu Zosamalira Munthu

◆Zinthu Zoyendetsedwa ndi Battery

◆Zogulitsa zomwe zili ndi Circuit Boards kapena Electronics

◆ Mababu Owala

◆Mafuta Ophikira

◆Chakudya choperekedwa ndi Aerosol kapena Bag-On-Valve

▍ Chifukwa chiyani MCM?

● Thandizo la akatswiri aukadaulo: MCM ili ndi gulu la akatswiri lomwe limaphunzira malamulo ndi malamulo a SDS kwa nthawi yayitali. Iwo ali ndi chidziwitso chakuya za kusintha kwa malamulo ndi malamulo ndipo apereka ntchito zovomerezeka za SDS kwa zaka khumi.

● Utumiki wa mtundu wa loop-loop: MCM ili ndi akatswiri olankhulana ndi ma auditors ochokera ku WERCSmart, kuonetsetsa kuti kalembera ndi kutsimikizira zikuyenda bwino. Pakadali pano, MCM yapereka chithandizo cholembetsa cha WERCSmart kwa makasitomala opitilira 200.

Kusintha Maselo a 7.12 (mabatire ndi electrochemical capacitor): Kwa maselo a Li-ion omwe amatha kuchargeable, kuyesa pansi pa annex E kumafunika, popanda kuganizira za UL 1642. Maselo amafunikanso kufufuzidwa ngati akwaniritsa zofunikira za mapangidwe otetezeka, monga zinthu ndi malo a insulator, kuphimba anode ndi cathode, etc.
Onjezani 18 Pakuchulukira Pansi Pakutha: Yang'anani mphamvu yamakina a batri ndikuchulukira pansi. Pali zikhalidwe ziwiri zoyezetsa: choyamba ndi chodzaza kwambiri pansi pa kutayidwa kumene panopa ndipamwamba kuposa momwe amachitira pakalipano koma otsika kuposa panopa a chitetezo cha BMS overcurrent; yachiwiri ndi yapamwamba kuposa BMS pachitetezo chapano koma chotsika kuposa 1 chitetezo chapano.
