Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces HY/T 107-2008 "Test Method for Rolled Reverse Osmosis Membrane Modules". Compared with HY/T 107-2008, except for editing
The main technical changes outside of the sexual modification are as follows.
---Revised the standard name "Test method for roll-type reverse osmosis membrane modules" and changed to "Test method for roll-type reverse osmosis membrane elements", standard text
Modify accordingly;
--- Deleted "GB 17323 Bottled Purified Drinking Water" in the normative references (see.2008 edition 2);
--- Modify the terms and definitions "rolled reverse osmosis membrane", changed to "rolled reverse osmosis membrane element" and redefined (see 3.1,.2008
Version 3);
--- Added the definition of "completeness" in terms and definitions (see 3.2);
---Added the definition of "air tightness" in terms and definitions (see 3.3);
--- Added the definition of "permeability of membrane element" in terms and definitions (see 3.4);
--- Deleted the type of roll-type reverse osmosis membrane element (see.2008 edition 4);
---Added the requirement of "distilled water or deionized water" in test reagents (see 4.1);
---Modified the penetration performance test conditions (see 4.3,.2008 version 5.2, 5.3);
---Modified the membrane element sealing leakage point test as the membrane element integrity test (see 5.1,.2008 edition 6.2);
---Modified the schematic diagram of the structure of the membrane element air tightness test device (see 5.2.1,.2008 edition 6.1.1);
---Modified the air tightness test method of membrane elements (see 5.2.2,.2008 edition 6.1.2);
--- Modified the requirements for the preparation of membrane element permeability test (see 5.3.2,.2008 edition 6.3.2);
---Modified the calculation formula of water flux in membrane element permeability test (see 5.3.4.3,.2008 edition 6.3.4.3);
---Modified the calculation formula of salt removal (de) salt rate in membrane element permeability test (see 5.3.4.5,.2008 edition 6.3.4.5).
