I-EN 12520 ibhekisa kwindlela eqhelekileyo yovavanyo lwezihlalo zangaphakathi, ejolise ekuqinisekiseni ukuba umgangatho kunye nokusebenza kokhuseleko kwezihlalo kuyahlangabezana neemfuno eziqhelekileyo.

Lo mgangatho uvavanya ukuqina, uzinzo, imithwalo emileyo kunye neguqukayo, ubomi bolwakhiwo, kunye nokusebenza kwezihlalo ezichasene nencam.

Kuvavanyo lokuhlala ixesha elide, isihlalo kufuneka sijonge amawaka eemvavanyo ezilinganisiweyo zokuhlala kunye nokuma ukuze kuqinisekiswe ukuba akukho sinxibo sibalulekileyo okanye umonakalo esihlalweni ngexesha lokusetyenziswa. Uvavanyo uzinzo ihlola uzinzo kunye anti ukuncamisa isakhono isihlalo.

Isihlalo kufuneka sivavanywe olulinganisa ukuhanjiswa kobunzima ngesiquphe phakathi kwabantwana nabantu abadala ukuqinisekisa ukuba asophuki okanye asophuki ngexesha lokusetyenziswa. Uvavanyo lomthwalo osisigxina kunye noluguquguqukayo luhlola umthamo wokuthwala umthwalo wesihlalo, okufuneka uxhathise amaxesha amaninzi umthwalo oqhelekileyo ukuqinisekisa ukuba isihlalo sinokumelana nobunzima ngexesha lokusetyenziswa. Uvavanyo lobomi lwesakhiwo kukuqinisekisa ukuba isihlalo asiyi kufumana ukusilela kwisakhiwo okanye umonakalo ngaphakathi kobomi baso benkonzo eqhelekileyo.

Ngamafutshane, i-EN12520 ngumgangatho obaluleke kakhulu oqinisekisa uzinzo, ukuqina, kunye nokusebenza ngokukhuselekileyo kwezihlalo zangaphakathi ngexesha lokusetyenziswa.

Xa abathengi bethenga izihlalo zangaphakathi, banokubhekisela kulo mgangatho ukukhetha imveliso efanelekileyo.
