Foreword
All the technical contents in this Standard are mandatory.
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB 27953-2011 Hygienic Requirements of Disinfectant for
Infectious Focus. Compared with GB 29753-2011, this Standard has the major
technical changes as follows:
--- Add the normative references (see Clause 2 of this Edition);
--- Add terms and definitions of “concurrent disinfection”, “terminal disinfection” (see
Clause 3 of this Edition);
--- Add requirements of raw materials (see Clause 4 of this Edition);
--- Add the range of killing pathogenic microorganisms (see 7.1.1.1, 7.1.1.3, 7.1.1.4,
7.1.1.5, 7.1.1.6 of this Edition);
--- Add the selection requirements for disinfectants for contaminants of pathogens
of blood-borne infectious disease and special infectious disease (7.1.1.5, 7.1.1.6
of this Edition);
--- Include the label instruction manual requirements and precautions into Clause 8;
modify the precautions (see 8.1, 8.2 of this Edition);
--- Delete Appendix A; modify the dosage of the disinfectant; after adding the
treatment method of the prion contaminant, include it into the text (see 7.2 of this
Edition; Appendix A of 2011 Edition);
--- Delete the disinfection contents of drinking water, fruits and vegetables, hands
and skin (see 5.2.3, 5.2.4, 5.2.6 of 2011 Edition).
This Standard was proposed by and under the jurisdiction of National Health
Commission of PRC.

General Requirements on Disinfectant for
Infectious Focus
1 Scope
This Standard specifies the raw material requirements, technical requirements,
inspection methods, use methods, labels and instruction manual for disinfectants used
for disinfection of epidemic disease of infectious focus.
This Standard applies to disinfectants that disinfect the epidemic source of infectious
diseases or the environment contaminated by infectious pathogens.
