Foreword

GB/T 1479 "loose powder metal powder density determination" is divided into three parts. --- Part 1. Funnel method; --- Part 2. Scott capacity meter method; --- Part 3. Vibration funnel method. This section GB/T 1479 Part 3. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part Replaces GB/T 5061-1998 "Determination of Bulk Density of Metallic Powders - Part 3. Vibration Funnel Method". This section compared with GB/T 5061-1998 main changes are as follows. --- Added Chapter 2 Normative references; --- Added Chapter 4 symbols and definitions; --- revised the description of the vibrator; --- Revised measuring cup size and description; --- Increased support and base, positioning block requirements. This part is proposed by China Nonferrous Metal Industry Association. This part of the National Non-ferrous Metal Standardization Technical Committee (SAC/TC243) centralized. This part of the drafting unit. Iron and Steel Research Institute, Xi'an Ceylon Metal Materials Co., Ltd., Zigong Cemented Carbide Co., Ltd., West Department of Tak Tak Technology Co., Ltd. The main drafters of this section. Zhu Li Ran, Zhu Ji Lei, Li Hongyun, Li Juan, Li Siyuan, sinus micro-British. This part replaces the standards previously issued as. --- GB/T 5061-1985, GB/T 5061-1998. Determination of bulk density of metal powders Part 3. Vibration funnel method

1 Scope

GB/T 1479 provisions of this part of the vibrating funnel method loose metal powder density measurement method. This section applies to the funnel can not flow freely through the funnel method (see GB/T 1479.1) 5.0mm diameter metal funnel funnel. This section does not apply to vibration easily broken metal powder (GB/T 1479.2 specifies the bulk density of this powder test methods).

2 Normative references

The following documents for the application of this document is essential. For dated references, only the dated version applies to this article Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 1479.1 Determination of bulk density of metal powders - Part 1. Funnel method GB/T 1479.2 Determination of bulk density of metal powders - Part 2. Scott volumetric method

3 principle

The powder is charged into a funnel with a vibrating device and vibrated under certain conditions. The powder is vibrated by a certain height from the hopper Free fall, fully loaded in the loose state of the known volume measuring cup. The mass per unit volume of loose powder indicates the bulk density of the powder.

4 symbols and definitions

The symbols and definitions involved in this section are shown in Table 1. Table 1 Symbols and definitions Symbol definition unit ρao vibration funnel method loose density g/cm3 m powder quality g V cup volume cm3

5 instruments

5.1 funnel Funnel shape and size requirements shown in Figure 1. 5.2 Vibrator The power frequency of the vibrator is 50Hz ~ 60Hz, the funnel vibrates at the frequency of 100Hz ~ 120Hz, the amplitude is 50μm ~
