Scope

Main Technical Content: 1. General Description of Standard Samples: The standard describes the packaging, specifications, and dimensions of the standard samples in this series. There are three types of standard samples in this series, named T/AQB-RM-1, T/AQB-RM-2, and T/AQB-RM-3, which are nonwoven fabrics made by the meltblown method. They are packaged in aluminum foil self-sealing bags, with five pieces per pack, each measuring Φ150mm in diameter. 2. Intended Use: The standard specifies the intended use of these standard samples. These standard samples are used in GB/T 32610 *Technical Specifications for Daily Protective Masks* and GB 2626-2019 *Respiratory Protection - Self-Suction Filter Respirators for Particulate Matter*. During testing, according to different standard methods, by measuring the filtration efficiency of these standard samples, the testing instruments and equipment are calibrated, verified, and adjusted to improve the accuracy and stability of the instruments, meet the standard testing requirements for meltblown fabrics and mask products, enhance the detection quality and level of mask filtration efficiency, and improve the overall quality of related industries and products. 3. Correct Use of Standard Samples: The standard specifies the correct use of these standard samples. According to GB/T 32610 *Technical Specifications for Daily Protective Masks* and GB 2626-2019 *Respiratory Protection - Self-Suction Filter Respirators for Particulate Matter*, under the testing environment of (25±5)°C and relative humidity of (30±10)%, the salt particle filtration efficiency of these standard samples is measured according to the testing methods specified in these standards. No pretreatment is required. 4. Storage and Transportation of Standard Samples: The standard specifies the storage and transportation conditions of these standard samples. These standard samples should be stored and transported at room temperature and in a light-free
