Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. This standard uses redrafted law revision adopted CIPACMT10 "water insoluble." This standard and CIPACMT10 "water insoluble" The main technical differences and the reasons are. --- Modify using only CIPACMT10 10.1 and 10.2 in cold water, hot water insolubles two methods. CIPACMT10 in 10.3 The method is mainly used 150μm aperture sieve Determination of water insoluble matter, taking into account not yet using this method for the determination of pesticides Water insoluble, are suspended for the drafting; CIPACMT10 10.4 Determination method of water insoluble pesticide agent, the present standard Determination of cold water insolubles can be replaced. --- Glass sand core crucible unified specifications for domestic generic G3 models. CIPACMT10 used G4 glass frit crucible deposit In the filter for a long time, easy to plug the shortcomings difficult to clean. --- CIPACMT10 10.2 Method 200mL stoppered glass cylinder used in the non-domestic glassware stereotypes, this standard The method set forth in stoppered glass cylinder using 250mL sample was dissolved. --- Increased pre-filter glass sand core crucible drying process requires an oven dried 1h 105 ℃, so as to achieve a constant weight. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee on Pesticides (SAC/TC133) centralized. This standard was drafted. Jiangxi Province Chemical Industry Institute. The main drafters of this standard. Ding teach, Yan Xiaoping, Xiao Weiwei, Gongbai Mei.
