EN 71 Amathoyizi Testing Izinsiza kusebenza Liquid Ukuvuza Testing Needle

Umkhiqizo ukwethulwa  Liquid Ukuvuza Testing Needle

Isetshenziselwa ukuhlola leakiness amathoyizi ketshezi egcwele.

Umkhiqizo kwemigomo Liquid Ukuvuza Testing Needle

Umkhiqizo Isici futhi Ukusebenza Liquid Ukuvuza Testing Needle

Sebenzisa

1. Beka ithoyizi imvelo (37 ± 1) ° C okungenani 4 amahora;

2. Sebenzisa 5 + 0.50N amandla noma iyiphi ingxenye ebusweni elingaphandle ithoyizi ngensimbi yenaliti ngemva kokukhipha ithoyizi kusuka imvelo pretreatment;

3. kancane kancane ukwandisa amandla ngaphakathi 5s futhi uyigcine 5s;

yi 4. Isahlulelo: Emva kokuphothulwa, isheke ngabe ithoyizi ukuvuza (ukubeka ayibe chloride iphepha endaweni lapho amandla sisetshenziswa);

5. Phinda test on ithoyizi at (5 ± 1) ° C okungenani 4H. (Qaphela: Emva 5 ° C test, awukwazi ukusebenzisa ayibe chloride iphepha ngoba kuyabanda.

Ukufingqa kungaholela emiphumeleni eyiphutha. )

Umkhiqizo Imininingwane Liquid Ukuvuza Testing Needle

Ukuhlola Amazinga                                         

ISO 8124-1 ASTM F963 EN-71

inqubo                                                      

Phakathi 30 s yokususa ithoyizi kusuka conditioning, sisebenzise amandla ka (5 + 0.50) N kwamanzi sangaphandle ithoyizi ngokusebenzisa steel inaliti nge ububanzi 1 mm 0.1 mm kanye engaba ichopho 0,5 mm 0.05 mm.
