Isibini esitshatileyo

IIMFUNO ZOKULUNGISELELA ISIQINISEKISO SESITHILI SESITHILI:

1. Akufuneki kubekho rocks kuyo nayiphi na inxenye yesibini esitshatileyo;

2. Umgama wokuvula phakathi kwekhava kwaye isihlalo masingaphantsi kwe-49 okanye i-52mm.

3. Isibini esitshatileyo asivumelekanga ukuba sikhulule emakhuluni;

4. Akufuneki kubekho ngaphezulu kwe-3 ye-sand hones enkulu kune-10mm2 kumphezulu wesibini. Ukongeza, indawo ekhulayo ayinakuba mkhulu kune-50mm2;

I-5. Indawo eqokelelweyo phezu kwe-zipper ayiyi kudlula kwi-150mm2;

I-6. Ukuphakama (okanye ubunzulu) bokuqonda (okanye uxinzelelo) kumphezulu wesibini kufuneka ungadluli kwi-1mm.

7. Akukho lulusu lwe-oxide kwinxalenye yoqhakamshelwano phakathi kwesibini kunye nombhobho wentsimbi, kunye nendawo ekhulayo ye-oxidation yamanye amalungu ayidluli kwi-150mm2;

8. Iirivets ezisetyenziselwa isibini esitshatileyo kufuneka sithobele izibonelelo ze-GB867. Ngamalungu aqengqelekayo, intloko eqengqelekayo kufuneka ibe li-1mm enkulu kune-Deameter yomngxunya we-rivet kwaye kufuneka ibe mhle kwaye ikhululekile.
