Foreword

This standard is drafted in accordance with regulations provided in GB/T 1.1-2009. The standard was proposed by China Building Materials Federation. The standard shall be under the jurisdiction of National Standardization Technical Committee of lightweight construction and decoration materials (SAC/TC 195). Drafting organizations of this standard. China Building Materials Academy, Shenzhen Grandland Decoration Group Co., Ltd., Taiyuan Lunjia Biological Engineering Co., Ltd., Foshan Shunde Gaoyi New Plastic Co., Ltd., Shenzhen Eli Environmental Protection Technology Co., Ltd., Fo Shan Shi Shun De Wen Bao Technology Co., Ltd., Inner Mongolia Wuhua Tianbao Mineral Resources Co., Ltd., Sichuan shengda forestry industry Co., Ltd., Shanghai Zhenao biological technology Co., Ltd., Fujian Yuhe Haoyue Biological Engineering Materials Co., Ltd., Beijing days of Rock Health Technology Co., Ltd., Hua Xia Beineng (Beijing) Ecological Technology Co., Ltd., and Zhongke Weiyikang (Beijing) ecology technology Co., Ltd. Main drafters of this standard. Ji Zhijiang, Wang Jimei, Li Shaoqiang, Wang Jing, Zhang Chaolun, Zeng Bin, Wu Shaoyong, Yang Shunxin, Wang Zixiang, Yu Gang, Feng Lian, Zhu Wenming, Chen Rongkun, Zhu Shengmei, Wang Zhixia, and Wang Zhongyong. From the date of implementation of this standard, JC/T 1016 2006 Testing on negative ion concentration of materials shall be abolished. Test method for air ion concentration of materials 1 Scope This standard specifies the terms and definitions, principles, test systems, test conditions, sample preparation, test procedure, calculation results, and test reports of test method for air concentration of materials. This standard applies to materials which can concentrate air ion, such as paint, panel, wallpaper, and putty. 2 Normative references The articles contained in the following documents have become part of this document when they are quoted herein. For the dated documents so quoted, all the modifications (Including all corrections) or revisions made thereafter shall be applicable to this document. JC/T 412.1-2006 Fiber cement flat sheets Part 1. Non-Asbestos Fiber cement flat sheets 3 Terms and definitions The following terms and definitions apply to this document. 3.1 Air ion Ions in air with negative or positive charge. 3.2 Air ion concentration of materials The measured increment of air ion in unit-time and in unit-area on material surface. The unit is [ions / (s·m2)]. 4 Principles Apply certain voltage to ion collector, so as to form an electric field to capture air ion. Leak the captured charge into a capacitor though leakage circuit. Then measure the air ion concentration of materials by continuously detecting the voltage change caused by air ion concentration of materials which is captured by capacitor. 5 Test system 5.1 Collector Collector is consisted of a group of equidistant high-voltage grilling, collecting grilling and Where. N - Air negative (positive) ion concentration of materials, the unit is ions / (s·m2). 10 Test reports The test report shall at least provide the following contents. — Number of this standard; — Test samples, including sample name, sample volume, sample preparation and sample type; — Test environmental conditions, including temperature, relative humidity and the test date; — Testing personnel; — Test results, including measured value of air negative (positive) ion of samples, measured value of blank air negative (positive) ion and Air negative (positive) ion concentration of materials. — Any factors that may affect the test result. ......
