防静电塑料周转筐是电子、电气元器件和设备的生产厂家用于生产、周转、贮存、包装所必备的，是有效地保护静电敏感免受静电损伤的必不可少的器具。防静电周转筐随着静电敏感器件的广泛应用，它的质量和防静电性能受到用户的极大关注。
同一个容器材料电阻的均匀性是参照GJB/105-98电荷泄放的要求而提出的，导电性是ESD防护材料重要性能，能让电荷泄放到地，在同一个容器上电阻率的均匀性能让电荷均匀地分布在整个材料上。静电全衰期的时间测量是参照GJB/Z 105-98 H3.2.4执行。
静电衰减性能测试对于均匀材料(体积表面导电性的范围之内时)都呈现出复杂的测量问题；非均匀的体积、表面两种导电材料系统呈现极端复杂的测量问题。对于复合结构的材料而言，材料的电阻率(体积电阻率或表面电阻率)对静电衰减时间的相关性可能是前后矛盾，为了使静电分别规定为小于10秒和2秒。
规定对耐热性能试验温度为80℃，比国标规定的60℃有所提高。物理机械性能抗冲击强度，由于电子行业的周转筐结构形式多样性，对于一次性注塑成型周转筐和元件盒可以采用跌落试验，但是对于组装成型的周转架和车难以实行整体跌落试验，为此暂定为对塑件做缺口冲击试验，保证周转筐的可靠性。

Anti static plastic basket turnover is electronic, electrical components and equipment manufacturers for the production, storage, packaging, turnover is necessary, effective protection of electrostatic sensitive from electrostatic damage essential apparatus. Anti-static turnover basket with electrostatic sensitive devices are widely used, its quality and antistatic performance by the user's attention.
The same container material resistance uniformity is the reference GJB/105-98 charge discharge requirement, conductivity is ESD protective material performance, can make the charge discharge to the earth, in the same container homogeneous resistivity properties allow charges to be uniformly distributed throughout the material. Static full decay time measurements are made with reference to GJB/Z 105-98 H3.2.4 implementation.
Electrostatic charge decay test for homogeneous material(volume surface conductivity range)presents a complex measurement; non uniform volume, the surface of two kinds of conductive material system presents complicated measurement. For composite structure of material, the material resistivity(volume resistivity or surface resistivity)of electrostatic charge decay time correlations may be contradictory, in order to make electrostatic separate provisions are made for less than 10 seconds and 2 seconds.
The provisions of the thermal performance test temperature is 80 ℃, 60℃than standard improvement. Physical and mechanical properties of impact strength, due to the electronic industry turnover basket structure diversity, for a one-time injection molding turnover basket and the component box can adopt the drop test, but for assembling turnover frame and the vehicle to execute overall drop test, this is tentatively scheduled for the plastic parts do notch impact test, ensure the reliability of turnover basket.
