Foreword
In this Standard, Section 4.10 is recommendatory and other Sections are mandatory.
This Standard replaces GB 19083-2003 "Technical Requirements for Protective Face
Mask for Medical Use".
Compared with GB 19083-2003, this Standard has the major changes detailed as follows:
——The applicable “Scope” of the standard was revised;
——The "Normative References” was supplemented and revised;
——The terms and definitions were added and changed;
——The dimensional requirement of mask was deleted;
——The length requirement of nasal splint was deleted;
——The "Fit" requirement and test method were added;
——The technical requirement of "Skin irritation" was revised according to GB/T
16886.10-2005 and the test method was defined;
——The technical requirement of markings and instructions for use was deleted;
——The original test method for oxirane residue specified in GB 15980-1995 was
replaced by the gas chromatography method of GB/T 14233.1-2008;
——The test method of microorganism indexes was revised.
In this Standard, Appendix B is normative and Appendix A is informative.
This Standard was proposed by State Food and Drug Administration.

Technical Requirements for Protective Face Mask
for Medical Use
1 Scope
This Standard specifies the technical requirements, test methods, markings and
instructions for use, packaging, transportation and storage for protective face mask for
medical use (hereinafter referred as mask).
This Standard is applicable to non-powered air-purifying medical protective face mask -
used in medical service environments to filter particulate matters in air and to separate spray,
blood, body fluid, secretion, etc.

3 Terms and Definitions
For the purposes of this Standard, the following terms and definitions apply.
3.1
Filtering efficiency
The percentage number of filtering particulate matters in air under specified conditions
3.2
Fit
The degree of mask periphery fitting to the face of a specific user
3.3
Fit factor
The ratio of the testing agent’s concentration outside the mask to the testing agent’s
concentration leaking into the mask, which is quantitatively measured during the testees
wearing masks for simulating actions, process and operation
4 Technical Requirements
4.1 Basic requirement of mask
The mask shall cover the wearer's nose and mouth and shall be of a good facial fit and
without broken holes, stain or expiratory valve.
4.2 Nasal splint
4.2.1 The mask shall have a nasal splint.
4.2.2 The nasal splint shall be adjustable.

4.3.1 The mask’s harness shall be adjustable conveniently.
4.3.2 The mask’s harness shall be of sufficient strength to fix the mask. The breaking strength
of the junction between each mask harness and the mask body shall not be less than 10N.
4.4 Filtering efficiency
With the gas flow at 85L/min, the filtering efficiency of mask to non-oily particles shall
comply with the requirements specified in Table 1.
