Determination of flow plastic
1 Scope
This standard specifies two methods, namely Method A and Method B. By measuring the powder or granular plastic funnel outflow time is measured
Its liquidity.
A obtained by the method of processing and performance-related information, and the method B is designed for process control during the production and design.
Note. The method described is not available for all powders and granular plastic.

GB/T 2918-1998 standard plastic sample conditioning and environmental tests (idt ISO 291.1997)
3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Certain quality or volume of a predetermined size sample outflow funnel amount of time, expressed in seconds.
Principle 4
Measuring a weight or volume of the sample size of the outflow funnel predetermined amount of time.
5 Instruments
5.1 funnel, funnel shape and dimensions are shown in Figure 1 and Table 1, you can use an ordinary test funnel or leak test with switchable interface
Bucket, funnel shall be made of metal (such as stainless steel), the inner surface should be careful polishing, assembly should be closing the outlet means (such as a metal sheet), a drain
Ground fighting should be to eliminate static electricity.
5.2 funnel holder for holding the funnel perpendicular to the axis, for example, a vertical carriage mounted on a metal ring.
5.3 stopwatch, accurate to 0.1s, or selection method has the same accuracy of other measurements of time.
5.4 Balance, accurate to 0.1g.
6 Conditioning
Unless otherwise specified, after the receipt of the samples should be tested at room temperature. If the test environment may affect the test results, it should be based on
GB/T 2918-1998 specified in (23 ± 1) ℃, relative humidity (50 ± 5)% condition adjusting 24h, and tested in the same environment.
