JinKeLian QNB ISO outFlow Cup has three types of outflow Viscosity Cups, QNB No. 3, No. 4 and No. 6. This ISO outFlow Cup is developed by integrating the relevant provisions of the national standard and the international standard. It adopts stainless steel material. QNB No. 3/No. 4/No. 6 ISO outFlow Cup is used to test the outflow time of Newtonian or near-Newtonian liquids, and the applicable test outflow time range is 30s~100s.
1. International standard ISO2432-1993 "Determination of outflow time with outFlow Cup for paints and varnishes" (fourth edition)
2. National standard GB/T6753.4-86 "Determination of coating flow time - ISO Flow Cup method"
