Face mask test standards
In addition to medical protective masks and daily protective masks, our daily contact masks also have disposable protective masks, knitted masks, mask paper and other products. In addition, there is a self-priming filter type anti-particle mask, which was later changed to a self-priming filter type anti-particulate respirator for the purpose of describing more accurate national standards. Today we will give you a detailed introduction to the testing standards and items of these masks.
1. Medical protective mask detection
The detection standard is GB 19083-2010 "Technical Requirements for Medical Protective Masks". Test items include basic requirements test, fit, nose clip test, mask band test, filtration efficiency, air flow resistance test, synthetic blood penetration test, surface moisture resistance test, residual ethylene oxide, flame retardant performance, skin Stimulus performance testing, microbiological testing indicators, etc. Among them, the microbiological testing items mainly include total bacterial colonies, coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococci, and total fungal colonies.
Two, often protective mask detection
The detection standard is GB / T 32610-2016 "Technical Specifications for Daily Protective Masks". The testing items mainly include basic requirements testing, appearance requirements testing, intrinsic quality testing, filtration efficiency, and protection effects. Among them, the internal quality testing items mainly include color fastness to rubbing, formaldehyde content, pH value, content of decomposable carcinogenic aromatic amine dyes, residual ethylene oxide, inhalation resistance, exhalation resistance, mask band and the link with the mask body Breaking strength, expiratory valve cover fastness, microorganisms (coliforms, pathogenic pyogenic bacteria, total fungal colonies, total bacterial colonies)
3. Mask paper detection
The detection standard is GB / T 22927-2008 "mask paper". Test items mainly include tightness, tensile strength, air permeability, longitudinal wet tensile strength, brightness, dustiness, fluorescent substances, delivery moisture, hygiene indicators, raw materials, appearance, etc.
4. Detection of disposable medical masks
The testing standards are YY / T 0969-2013 "Disposable Medical Masks". The testing items mainly include appearance, structure and size, nose clips, mask bands, bacterial filtration efficiency, ventilation resistance, microbial indicators, residual ethylene oxide, biological Academic evaluation. The microbial indicators mainly detect the total bacterial colonies, coliforms, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococci, and fungi. The second biological evaluation items include cytotoxicity, skin irritation, and delayed-type hypersensitivity.
V. Knitted mask detection
The testing standard is FZ / T 73049-2014 "Knitted Masks". The testing items are mainly appearance quality, intrinsic quality, pH value, formaldehyde content, decomposable carcinogenic aromatic amine dye content, fiber content, soaping color fastness, water fastness, saliva resistance fastness, rubbing fastness , Color fastness to perspiration, breathability, odor, etc.
Six, PM2.5 protective mask detection
The testing standards are T / CTCA 1-2015 "PM2.5 protective mask", TAJ 1001-2015 "PM2.5 protective mask". The testing items mainly include apparent testing, formaldehyde, pH value, temperature and humidity pretreatment, decomposable carcinogenic ammonia dyes, microbial indicators, filtration efficiency, total leakage rate, respiratory resistance, connection force between the mask strap and the body, dead space, etc.
Seven, self-suction filter type anti-particle mask detection
The detection standard for self-priming filter anti-particle masks was originally GB / T 6223-1997 "Self-priming filter anti-particle masks" has now been abolished. Now mainly based on GB 2626-2006 "Respiratory protective equipment. Self-priming filter type anti-particulate respirator" for testing, specific testing items include material quality testing, structural design requirements testing, appearance testing, filtration efficiency testing, leakage, disposable Mask TILv, replaceable half mask TI test, full mask TI test, breathing resistance, breathing valve test, breathing valve air tightness, breathing valve cover test, dead space, visual field evaluation, headband, connecting parts and connections Stress test, lens test, air tightness test, flammability test, cleaning and disinfection test, packaging, etc.
