Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 1914-2007 "chemical analysis of filter paper."
This standard compared with GB/T 1914-2007, the main changes are as follows.
--- Modify the normative references;
--- Qualitative filter paper broken into long-term tensile strength;
--- Increased dry burst resistance, anti-alkaline and D65 fluorescence brightness of three technical indicators;
--- Brightness to D65 brightness, separation performance of the technical requirements to qualified;
--- Improve the water filtration time and wet bursting determination.
