GB/T 22868-2008"Ibhola yomnyazi" ichaza ukuba ibhola yomnyazi yahlulwe yaba yibhola yomnyazi yabantu abadala (iNombolo yesi-7), ibhola yomnyazi yabantu abadala yabasetyhini (iNombolo yesi-6), ibhola yomnyazi yolutsha (iNombolo yesi-5), nebhola yomnyazi yabantwana (iNombolo yesi-3) ngokwenani labantu abayisebenzisayo kunye nebhola yomnyazi. Umjikelo webhola. Isikhumba sebhasikithi kunye nesikhumba esisetyenzisiweyo sinokubola iidayi zeamine ezinevumba elimnandi ≤ 30mg/kg, kunye neformaldehyde yasimahla ≤ 75mg/kg. Umphezulu wesikhumba sokwenziwa, ufele olwenziweyo, kunye nesikhumba esiphinde sasetyenziswa ukwenza imisebenzi yemihla ngemihla yebhasikithi akufunekanga ibe neziphene ezinje ngamaqamza okanye i-delamination, kunye nokuqhekeka okuncinci kuvumelekile. Kukho iziphene ezi-5 ezincinci kunye nendawo ye-≤ 5mm2 evunyelwe; Ubunzulu be-creases kwi-rubber spherical surfaces ingaba ngu-≤ 0.5mm, kwaye iziphene eziqokelelweyo ze-spherical zivumelekile ukuba zibe ≤ 7cm2; Ububanzi be-spherical seam okanye i-groove yi-≤ 7.5mm. Ukwahlukana kwe-Basketball circumference ≤ 5mm, ukuphambuka okuvumelekileyo koxinzelelo lomoya ukuhla emva kweeyure ze-24 zokunyuka kwamaxabiso kunye nokubekwa kwe-static ≤ 15%; Emva kweempembelelo ze-1000, izinga lokwandiswa ngu-≤ 1.03, ixabiso le-deformation ≤ 3mm, kwaye izinga loxinzelelo lokunciphisa ngaphakathi kwebhola ngu-≤ 12%.
GB 23796-2008"I-Basketball Stand" imisela ukuba i-backboard kufuneka ibexande, kwaye imiphetho yayo emeleneyo kufuneka ibe perpendicular enye kwenye. Umahluko phakathi kwee-diagonals ezimbini akufanele udlule i-6mm. Ukuba i-backboard ikhuselwe ngumda wensimbi, umgca womda wangaphandle we-backboard kufuneka ube ubuncinane ubuncinane be-20mm ububanzi kwaye ungathintelwa ngumda wesinyithi. I-backboard kufuneka iprintwe ngemigca yemida engaphakathi nangaphandle, kunye neebhodi ezingemuva ezikhanyayo ezinemida emhlophe yangaphakathi nangaphandle kunye neebhodi ezingemuva ezingacacanga ezinemida emnyama. Umphetho wenziwa ngentsimbi eqinileyo, unomcu wediamitha oyi-16mm ukuya kuma-20mm kunye nobubanzi obungaphakathi obuyi-450mm ukuya kuma-459mm. Umnatha webhasikithi wenziwa ngentambo emhlophe enemingxuma eyi-12, kwaye ubude bomnatha bungama-400mm ukuya kuma-450mm.
