Foreword
This standard was drafted in accordance with the rules given in GB/T 1:1-2009:
This standard replaces GB/T 22623-2008 "Prochloraz technical", GB/T 22624-2008 "Prochloraz EC" and GB/T 22625-
2008 "Prochloraz Water Emulsion", this standard is mainly compared with GB/T 22623-2008, GB/T 22624-2008, GB/T 22625-2008
The main technical changes are as follows:
---Combine GB/T 22623-2008, GB/T 22624-2008, GB/T 22625-2008 into one standard;
---Revised the quality score index of prochloraz technical from not less than 95:0% to not less than 97:0% (see 3:2, GB/T 22623-2008
3:2);
---The original drug of 2,4,6-trichlorophenol mass fraction index in prochloraz was revised from no more than 0:5% to no more than 0:2% (see 3:2,
3:2 of GB/T 22623-2008); the content of emulsifiable concentrates was revised from not higher than 0:2% and not higher than 0:3% to not higher than 0:1%
(See 3:2, 3:2 of GB/T 22624-2008); In water emulsion, it is revised from not higher than 0:2% and not higher than 0:3% to not higher
Less than 0:1% (see 3:2, 3:2 of GB/T 22625-2008);
---The moisture index in the original prochloraz is revised from no more than 0:5% to no more than 0:3% (see 3:2, GB/T 22623-2008
3:2);
--- Prochloraz EC has been added to the control project indicators for long-lasting foaming control (see 3:2, GB/T 22624-2008, 3:2);
---Modified the liquid chromatography determination method (see 4:4, 4:3 of GB/T 22623-2008, 4:3 of GB/T 22624-2008,
4:3 of GB/T 22625-2008);
---Modified the liquid chromatographic determination method of 2,4,6-trichlorophenol (see 4:5, 4:4 of GB/T 22623-2008, GB/T 22624-
4:4 of:2008, 4:4 of GB/T 22625-2008);
---The acceptance period of prochloraz technical is 1 month changed to 2 years of quality assurance period (see 5:2, GB/T 22623-2008, 5:6):
