兩種方法，即方法A和方法B。是通過測量粉末或粒狀塑料流出漏斗的時間來測定其流動性。由方法A可獲得與加工性能相關的信息，而方法B則是專為生產期間過程控制而設計的，PVC樹脂
this standard specifies two methods: method A and method B.It is measured by measuring the flow time of powder or granular plastic out of the funnel.Method A can obtains information related to processing performance, while method B is designed for process control during production, PVC resin
二.參照標準standard：
GB∕T 21060-2007《塑料 流動性的測定》，；ISO 6186-1998《塑料 流動性的測定》
三.測量原理principle：以已知質量或體積的試樣流出規(guī)定尺寸的漏斗所用的時間來表示.
Indicate by the needed time which a certain mass or volume of sample outflow the prescribed dimensions funnel.
四.參數資料
漏斗：漏斗帶有可轉換接口，不銹鋼材質，內壁拋光處理；漏斗出口帶控制閥門，漏斗配置接地線.
Funnel: funnel with convertible interface, stainless steel, inner wall with polishing treatment. Funnel outlet with control valve, Funnel has grounding wire to eliminate the impact of static electricity on the test results.
漏斗上口徑為：110mm；出口孔徑分別為：10±0.05mm,高度為：140mm；15±0.05mm, 高度為：133mm；25±0.05mm，高度為：120mm三種規(guī)格，角度40度；
參照標準要求如果測試的試料流動性比較差，不流動或根本流不動時，因而更換口徑的漏斗試驗，并在試驗報告中注明。
The upper opening diameter of the funnel: 110mm. The outlet diameter respectively: 10±0.05mm,height: 140mm. 15±0.05mm,height: 133mm. 25±0.05mm，height：120mm in three specifications. Angle is 40 degrees. According to the standard requirements if the liquidity of the test sample is poor, unable to flow compley or not at all, therefore the diameter of funnel is changed in test, and indicated in the test report.
五.本儀器配置：試驗支架用于支持漏斗的穩(wěn)定性
This instrument is equipped with bracket which use for support the stability of funnel.
4..主要組成部分：底座、支架、出口控制閥門、漏斗、秒表、鋼尺，毛刷、說明書、合格證、保修卡
Main components: base, bracket, outlet control valves, funnel, stopwatch, steel ruler, brush, manual, certificate, warranty card.
