Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB 28234-2011 "Safety and Sanitation Standard for Acidic Oxidation Potential Water Generator", compared with GB 28234-2011
The main technical changes are as follows.
---Modified the scope of application (see Chapter 1, Chapter 1 of the.2011 edition);
---Added "acid electrolyzed water generator", "slightly acidic electrolyzed water generator", "acidic electrolyzed water", "slightly acidic electrolyzed water" and "no diaphragm"
The definition of "type electrolyzer" (see 3.1, 3.3, 3.4, 3.6, 3.8);
---Modified the definition of "acid oxidizing potential water" (see 3.5, 3.2 and 5.1.3 of the.2011 edition);
--- Deleted "Name and Model" (see Chapter 4 of the.2011 edition);
--- Deleted the "basic structure diagram of the acidic oxidation potential water generator" (see 5.1.1 and Figure 1 of the.2011 edition);
--- Deleted the requirement that "the normal service life of the generator should be ≥ 5 years" (see 5.1.4.1 of the.2011 edition);
---Modified the requirements of "Acid Oxidation Potential Water Generation" (see 4.2.1.6, 5.3.1.6 of the.2011 edition);
---Added "simulation test and field test should meet the requirements of WS628 and "Disinfection Technical Specification" (2002 Edition)" (see 4.2.2.3
And 4.3.2.3);
--- Deleted the "Electrical Safety of Acidic Oxidizing Potential Water Generator" requirement (see 5.1.4.4 of the.2011 edition);
--- Added "Slightly acidic electrolyzed water generator technical requirements, application scope and use methods" and other content (see 4.3, 5.2 and Chapter 6);
---Added the "acid electrolyzed water electrolyzer, conveying pipes, storage containers and other main components dissolved in
And protective materials hygiene and safety evaluation specifications" (2001 edition) requirements for testing" (see 9.1).
This standard was proposed and managed by the National Health Commission of the People's Republic of China.
The previous versions of the standard replaced by this standard are as follows.
---GB 28234-2011.
