Summary: This standard specifies the requirements funnel outflow from loose material (powder or pellets) performance measurement method density. When this standard is applied fairly thick material, the upper part of the cylinder due ruler Calibrating error will be introduced when the extra samples, so the test results may generate errors. If the density molded plastic molding under similar conditions, the performance of the relative density relative volume molding loose or evaluate a certain value.

Foreword

This standard is amended to adopt ISO 60. 1977 (confirmed on September 20,.2005) "Plastic --- apparent material can flow out from the specified funnel Determination of degree "(in English). This standard was drafted in accordance with ISO 60. 1977. The main differences between this standard and ISO 60. 1977 are. --- Added "Normative references" chapter (Chapter 2); --- Added B type funnel (3.4) also available when testing powder; --- Increasing the test sample twice the test shall not be repeated requirements (4.3); --- Increasing the test results to retain the two significant figures (Chapter 5); --- Added "Precision" chapter (Chapter 6). This standard replaces GB/T 1636-1979 "Apparent density of molding materials test methods." The main differences between this standard and GB/T 1636-1979 are. --- This standard uses the ISO 60. 1977 standard name; --- Removed the 1979 version of the national standard B, the scope of the application has been adjusted (Chapter 1); --- Added "Normative references" chapter (Chapter 2); --- Each batch of material was measured three times modified to conduct two measurements (4.3); --- Added "Precision" chapter (Chapter 6). This standard is proposed by China Petroleum and Chemical Industry Association. This standard by the National Plastics Standardization Technical Committee (SAC/TC15) centralized. This standard was drafted. Sinopec Beijing Yanshan Branch Institute of resin applications. The main drafters of this standard. Wang Ling Xiao, Xu Yuezheng, Xu Guiqin, Wang Xiaoli, Shi Yingqiu, Zhang Ruhai. This standard replaces the standards previously issued as follows. --- GB/T 1636-1979. Plastic can flow out of the specified funnel material Determination of apparent density

1 Scope

This standard specifies the method of determining the apparent density of loose material (powder or granule) that can flow from the specified funnel. NOTE The method of determining the apparent density of loose molding compounds that do not flow from a given funnel can be found in ISO 61. 1977. This standard applies to thicker materials, as the ruler scrape the upper cylinder excess sample will introduce errors, so the test results can be Can produce errors. If the molding material in the molding conditions under the density, the apparent density for the evaluation of molding material relative looseness or relative volume of a certain value.
