《GB/T 1741-2007漆膜耐霉菌性测定法》由TC5(全国涂料和颜料标准化技术委员会)归口,主管部门为中国石油和化学工业联合会。
本标准代替GB/T 1741-1979(1989)《漆膜耐霉菌测定法》。
本标准规定了建筑涂料中的内、外墙漆膜耐霉菌性能测试方法及结果评定。
其他漆膜耐霉性能的测定也可参照本标准执行。
本测试应该由具有一定微生物知识的人员操作。
本标准适用于内墙和外墙漆膜耐霉菌性能的测定,其他类型的漆膜耐霉菌性可参照本标准测定。
本标准与GB/T 1741-1979(1989)相比,主要技术差异为:
―――形式更加严谨。本标准划分为范围、规范性引用文件、术语和定义、试验原理、试验条件、霉菌菌种及混合霉菌孢子(种子)悬浮液的制备、检验程序、结果观察共8章。
―――修改了试验方法与试验时间。前版根据不同试样选择试验方法,即甲法和乙法,这两种方法实际上为同一试验方法,即培养皿法,其试验时间为14d。本标准的试验方法分为培养皿检测法与湿室悬挂法两种,试验时间为28d。
―――对仪器设备要求更高。本标准增加了恒温恒湿培养箱、湿度计、霉菌孢子液喷雾箱、生物安全柜、冰箱等试验设备。
―――对漆膜制备作了要求。
―――试验菌种的选择更具科学性,更符合实际使用环境。
―――增加了阳性对照试验与阴性对照试验,以判断试验的可靠性。
―――对孢子悬浮液孢子浓度作出规定。
―――增加持久性防霉试验内容。
―――修改了评级方法。
Scope
This standard specifies the test method and result evaluation of the mold resistance performance of interior and exterior wall paint films in architectural coatings. Determination of mold resistance of other paint films can also refer to this standard. This test should be performed by personnel with some microbiological knowledge. This standard is applicable to the determination of the mold resistance of interior and exterior wall paint films. The mold resistance of other types of paint films can be measured with reference to this standard.
