3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Mass per unit volume of dust in the air, in units of milligrams per cubic meter (mg/m3).
4 General requirements
4.1 measuring machine dust concentration, dust is generated around the other machine should be stopped.
Measuring 4.2 machine dust concentration should be under normal operating conditions specified in the design prone to dust under cutting conditions of work or larger
30min after. There suction device machine, vacuum devices should be in working condition.
4.3 before and after sampling, weighing filters should use the same analytical balance.
4.4 measuring dust filters usually with a static, it affects the accuracy of weighing and, therefore, should be removed before each weighing static electricity.
5 measuring principle
Machine tools with dust collection filter of known mass, the incremental mining and gas membrane machine dust concentration is calculated.
6 Measuring Tools
Dust concentration measuring tool, mainly in the following measuring instruments and apparatus.
--- With a diameter of 40mm of vinyl chloride or other measuring dust filter membrane;
--- Dust sampler. Includes sampling and sample clip in two parts, the performance and technical specifications should be consistent with the provisions of GB/T 17061; and
--- Analytical balance. a sense of the amount of 0.1mg;
--- Stopwatch or other timer;
--- Dryers. built-in color gel;
---tweezers;
--- In addition to static.
7 Measurement
7.1 Membrane preparations
7.1.1 Drying. pre-weighing, the filter was placed in the dryer for more than 2h.
