G275 Dry Flotting Tester is used to test the shedding and shedding performance of medical clothing such as surgical gowns and clean clothing,as well as non-woven fabrics under dry conditions.
Applicable standards:
YY/T0506.4,ISO9073.10,INDAIST160.1,DIN EN13795-2
Main parameters:
1.Twisting speed:60 times/minute;
2.Twisting angle/stroke:180°/120mm;
3.Sample fixture:82.8mm;
4.Laser particle counter testing range:Collect samples ranging from 0.3 to 25.0um;
5.Laser particle counter flow rate:28.3L/min,±5%;
6.Sample testing data storage:3000;
7.Timer:1-9999 times.
Operation:
1.Firstly,prepare the accessories and test samples;
2.Open the transparent test box cover and allow clean air to flow into the empty box;
3.Turn on the instrument power and enter the LCD screen operation interface;
4.Before the experiment,confirm that there are less than 100 particles greater than or equal to 0.5 microns in the test box within 30 seconds;
5.If this requirement is not met,the step should be repeated;
6.After everything is ready,fix the sample on the rollers on both sides of the test box;
7.Reinstall the transparent test box cover;
8.On the LCD screen interface,set the number and running speed parameters;
9.Start running;
10.The sample is subjected to continuous twisting and compression movements inside the testing box;
11.When the set parameters are reached,the instrument automatically stops;
12.Open the test box cover and take out the sample;
13.After the experiment is completed,turn off the instrument;
14.When the sample is twisted during the test,air is extracted from the test box,and the particles in the air are counted and classified using a laser dust particle counter to evaluate the test results.
