Analysis of KP95 masks on GB2626 standard testing
When we were buying masks and protective products, did you notice the words on the above implementation standards? Of course, these industry standards are indispensable for a safe and qualified product. What production testing standards does our country have for masks? Let’s take a look. See! What are the standards for mask kp95gb2626? At present, the main standards for masks in my country include GB 2626-2006 'Respiratory Protective Equipment Self-priming Filter Type Anti-Particulate RespiratorAt present, the common masks in China are basically four standard systems: national standard, American standard, EU standard and Japanese standard. Note: The beginning of YY represents the pharmaceutical industry standard, and the beginning of GB represents the national standard, that is, the national standard. 1. The labor protection mask standard GB 2626-2006 'Respiratory Protective Equipment Self-priming Filtered Particle Respirator' was promulgated by the former General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee. It is a mandatory standard for the full text and was implemented on December 1, 2006. The protection objects stipulated by the standard include all kinds of particulate matter, including dust, smoke, fog and microorganisms. It also stipulates the production and technical specifications of respiratory protective equipment, and the material, structure, appearance, performance, and filtration efficiency of dust masks ( Dust resistance rate), breathing resistance, testing methods, product identification, packaging, etc. all have strict requirements. The standard divides masks into three levels: 90 (KN90, KP90), 95 (KN95, KP95), and 100 (KN100, KP100) according to their filtering efficiency. GB 2626-2019 Respiratory protection self-priming filter type anti-particle respirator, the revised version of the standard GB 2626-2019 'Respiratory protection self-priming filter type anti-particle respirator' was officially released on December 31, 2019, planned for 2020 It was formally implemented on July 1, 2005. The new standard added requirements for leak detection methods for respirator materials and detachable parts of the product. 2. Standards for medical and health masks There are currently two standards for medical protective masks in China. YY0469-2011 'Medical Surgical Masks' and GB19083-2010 'Technical Requirements for Medical Protective Masks' The testing of medical masks involves three in the existing national standards: YY/T 0969-2013 'Disposable Medical Masks 469-2011 'Medical Surgical MasksYY 0469-2011 'Technical Requirements for Medical Surgical Masks' was issued by the State Drug and Food Supervision Administration as a standard for the pharmaceutical industry and was implemented on January 1, 2005. This standard specifies the technical requirements, test methods, markings and instructions for use, packaging, transportation and storage of medical surgical masks. The standard stipulates that the bacterial filtration efficiency of masks should not be less than 95%. GB 19083-2010 'Technical Requirements for Medical Protective Masks' was promulgated by the former General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee, and was implemented on August 1, 2011. This standard specifies the technical requirements, test methods, signs and instructions for use of medical protective masks, as well as packaging, transportation and storage. It is suitable for use in medical working environments to filter airborne particles and block droplets, blood, body fluids, secretions, etc. Self-priming filter medical protective mask. 4.10 of the standard is recommended, and the rest are mandatory. YY/T 0969-2013 'Disposable Medical Masks/T 0969-2013 also has strict requirements for the filtration efficiency of bacteria. 3. The standard for daily protective masks GB/T 32610-2016 'Technical Specifications for Daily Protective Masks' was issued by the former General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Management Committee. It is my country's first national standard for civilian protective masks. It was published on November 1, 2016. Day implementation. The standard involves mask raw material requirements, structural requirements, label identification requirements, appearance requirements, etc. The main indicators include functional indicators, particle filtration efficiency, expiratory and inspiratory resistance indicators, and adhesion indicators. The standard requires that masks should be able to safely and firmly protect the mouth and nose, and there should be no sharp corners and sharp edges that can be touched. It has detailed regulations on factors that may cause harm to human bodies such as formaldehyde, dyes, and microorganisms to ensure that the public can wear them. Safety when wearing protective masks. T/CNTAC 55-2020, T/CNITA 09104-2020 'Civilian Sanitary Masks' group standard, in March 2020, the 'Civilian Sanitary Masks' group standard led by the China Industrial Textile Industry Association was officially released. The issuance of this standard has filled the gaps in the standard in the field of my country's civil sanitary masks, and changed the current situation of no standards to follow and no standards to check in the market. 13 standard indicators escort the performance of masks.
