Meet Standards:

The RT-701B melt flow rate meter is suitable for determining the specified thermoplastic melt mass flow rate in the national standard “Determination of GB/T3682-2000 Thermoplastic Melt Mass Flow Rate and Melt Volume Flow Rate.” This standard is equivalent to using the provisions of ISO 1133:1997, which can also meet the ASTM D1238 test standard.

2 . Standard test load (kg ,8 grades)

1st grade :0.325kg = (piston stem +weight tray +heat insulation sheath +weight # 1) = 3.187N

2nd grade :1.200kg = (0.325+weight # 2  0.875) = 11.77N

3rd grade :2.160kg = (0.325+weight # 3  1.835) = 21.18N

4th grade :3.800kg = ((0.325+weight #4  3.475) =37.26N

5th grade :5.000kg = (0.325+weight #5   4.675) = 49.03N

6th grade :10.000kg = (0.325+weight #5  4.675+weight #6  5.000) =98.07N

7th grade :12.500kg = (0.325+ weight #5  4.675+weight #6  5.000+ weight #7  2.500) =122.58N

8th grade :21.600kg = (0.325+ weight #2  0.875+ weight #3  1.835+ weight #4 3.475+ weight #5  4.675+weight #6  5.000+ weight #7  2.500+weight #8  2.915) =211.82N

The test load relative error shall not be more than ±0.5% .
