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).
