Is the ISO No. 4 cup the same as the painted 4 cup _ what is the difference?
Abstract:
这篇文章对比了ISO四号杯和涂4杯的不同标准。ISO四号杯依据ISO 2431标准，设计用于测量粘度范围为34-135 cSt的油漆和涂料，其滤嘴直径为4毫米，流动时间为30-100秒。而涂4杯依据GB/T 1723-93标准，适用于测量流出时间不超过150秒的涂料，滤嘴直径为4±0.02毫米。虽然两者的滤嘴直径相同，但在流动时间和粘度范围上有所不同。
What is involved here are two different standards. The ISO No. 4 cup is based on the standard ISO 2431. It is designed for paints and other related products with a viscosity range of 34-135cSt. The diameter of the filter tip is 4mm. Viscosity cups with a flow time of 30-100 seconds.
The Tu 4 Cup is designed according to the standard GB/T 1723-93, and is suitable for measuring the conditional viscosity of paint and other related products (the outflow time is not more than 150 seconds, and the diameter of the filter tip is 4mm). Under certain temperature conditions, measure the time for the quantitative sample to completely flow out from the hole of the specified diameter.
