ISO (International Organisation for Standardization) isangano repasirese repasi rose reStandation (ISO nhengo yesangano). Kunyorwa kwezviyero zvepasi rose kunowanzoitwa neISO technical committees. Mushure mekupedza, chiyero chechirongwa chinofanirwa kutenderedzwa pakati penhengo dzeTechnical Committee yekuvhota, uye inokwana 75% yemavhoti inofanirwa kuwanikwa isati yaziviswa zviri pamutemo seyepasi rose. Iyo yepasi rose mwero ISO8124 yakanyorwa ne ISO/TC181, iyo Tekinoroji Committee yeToy Chengetedzo.
ISO8124 inosanganisira zvinotevera zvikamu, iro zita rakawanda kuchengetedzwa kwetoyi:
Chikamu 1: Mechanical uye Muviri Performance Safety Standard
ISO8124 Shanduro yemazuva ano yechikamu ichi chechiyero ndeye ISO 8124-1:2009, yakagadziridzwa muna 2009. Zvinodiwa muchikamu chino zvinoshanda kune zvese matoyi, kureva, chero chigadzirwa kana chinhu chakagadzirwa kana kuratidzwa zvakajeka kana kuitirwa kutamba nevana. pasi pemakore gumi nemana.
Ichi chikamu chinotsanangudza maitiro anogamuchirwa ezvimiro zvematoyi, sekupinza, saizi, chimiro, kucheneswa (semuenzaniso, ruzha, zvidimbu zvidiki, zvakapinza uye zvakapinza mipendero, hinge clearance), pamwe nemaitiro anogamuchirwa ezvimwe zvakasiyana-siyana zvematoyi. (semuenzaniso, yakanyanya kinetic simba repurojekiti ine inelastic magumo, shoma Angle yemamwe matoyi ekutasva).
Ichi chikamu chinotsanangura zvinodiwa zvematoyi uye nzira dzekuyedza dzemazera ese evana kubva pakuzvarwa kusvika pamakore gumi nemana ekuzvarwa.
Ichi chikamu chinodawo yambiro yakakodzera uye mirairo pane mamwe matoyi kana kurongedza kwavo. Zvinyorwa zveyambiro idzi nemirayiridzo hazvina kutaurwa nekuda kwekusiyana kwemitauro pakati penyika, asi zvinodikanwa zvakajairika zvinopihwa muAppendikisi C.
Hapana chinhu chiri muchikamu chino chinoratidzwa kuvhara kana kubatanidza kukuvadza kunogona kuitika kwezvimwe matoyi kana marudzi ematoyi akatariswa. Muenzaniso wekutanga: Muenzaniso wekukuvadzwa kwakapinza ndeye bonde remuromo wetsono. Kukuvadzwa kwetsono kwave kucherechedzwa nevatengi vekiti yekusonesa ematoyi, uye kushanda kwakapinza kukuvara kunoziviswa kune vashandisi kuburikidza neyakajairwa nzira dzekudzidzisa, nepo zviratidzo zveyambiro zvinomakwa pakurongedzerwa kwechigadzirwa.
Muenzaniso 2: Majekiseni ematoyi anewo kushandiswa kwekukuvara kwakabatana uye kunozivikanwa (senge: kusagadzikana panguva yekushandiswa, kunyanya kune vanotanga) vane hunhu hwekukuvadza kunogona kuitika (kupinza mupendero, kukuvadza kukuvadza, nezvimwewo), zvinoenderana neiyo ISO8124 chiyero chikamu ichi. zvezvinodiwa zvinofanirwa kuderedzwa kusvika padiki dhigirii.
Chikamu 2: Kupisa moto
Iyo yazvino vhezheni yechikamu ichi che ISO8124 ndeye ISO 8124-2: 2007, yakagadziridzwa muna 2007, iyo inodonongodza mhando dzezvinhu zvinopisa zvinorambidzwa kushandiswa mumatoyi uye zvinodikanwa zvekupokana nemurazvo wematoyi chaiwo kana akafumurwa kune zvidiki zvinopisa. Regulation 5 yechikamu ichi inoburitsa nzira dzekuyedza.
Chikamu 3: Kutama kwezvimwe zvinhu
Iyo yazvino vhezheni yechikamu ichi cheISO8124 ndeye ISO 8124-3: 2010, yakagadziridzwa muna Chivabvu 27, 2010. Ichi chikamu chinonyanya kudzora inorema simbi yezvinhu zvinosvikika muzvigadzirwa zvematoyi. Iyo yekuvandudza haishandure zvakatemwa zvinodikanwa zveiyo chiyero, asi inoita zvinotevera gadziriso pane mamwe asiri etekinoroji mazinga:
1) Chiyero chitsva chinotsanangura zvakadzama huwandu hwematoyi emidziyo inoda kuongororwa, uye inowedzera huwandu hwemachira epamusoro akaedzwa pahwaro hwekutanga edition,
2) Chiyero chitsva chinowedzera tsananguro ye "bepa nebhodhi",
3) Chiyero chitsva chachinja test reagent yekubvisa mafuta uye wakisi, uye iyo yakashandurwa reagent inopindirana neshanduro yazvino ye EN71-3,
4) Muyero mutsva unowedzera kuti kusavimbika kunofanirwa kutariswa kana uchitonga kana kuongororwa kwehuwandu kunosangana nezvinodiwa,
5) Muyero mutsva wakagadzirisa huwandu hwepamusoro hunofemeswa hweantimony kubva pa1.4 µg/zuva kuenda pa0.2 µg/zuva.
Izvo zvinodikanwa zvekugumira zvechikamu ichi ndeizvi:
Munguva pfupi iri kutevera, ISO 8124 ichawedzerwa zvikamu zvakati wandei, zvichiteerana: huwandu hwese hwezvinhu zvakanangana muzvinhu zvetoyi; Kutsunga kwephthalic acid plasticizers mune zvepurasitiki zvinhu, senge
polyvinyl chloride (PVC).
