芬兰M1认证
芬兰M1认证即M1 mission Classification of Building Materials。
芬兰被誉为纯净的千湖之国,同时,芬兰也是世界上森林覆盖率最高的几个国家之一(96%),其拥有完善的环境保护体系,环境标准的制定也处于欧洲领先水平。芬兰M1认证把所有的建筑材料按照有害物质释放量的大小被依次划分为M1、M2、M3三个级别,每级都选取不同的天然材料为标准同被检测物相比较。
Product Testing 产品测试
1 Product testing before classification 分级之前进行产品测试
Classification requires the product to be tested before sending in an application by an approved testing laboratory in accordance with the required methods.产品依照所需的测试方法在一个认可的实验室测试后,再提交认证申请进而进行分级。
2 Selection of testing laboratory 测试实验室的选择
Sample selection, analysis and measurements of material emissions must be performed at a competent and impartial laboratory approved by the classification working group. A list of approved laboratories can be found on the Internet. The applicant shall be responsible for documentation. 样本选择、分析、放射物质测试必须在一个能胜任的、公正的、经过分级工作组认可的实验室里进行。上有测试实验室的清单。
3.3 Testing methods 测试方法
Sampling, analysis and measurements of material emissions are to be conducted as stipulated in the following document:
Emission Classification of Building Materials: Protocol for Chemical and Sensory Testing of Building Materials
Following information shall be given :需要提供的资料
production date 生产日期
product delivery day 产品交割日期
以涂料为例,需测试产品以下几方面的特性:
The products are to be tested with regard to the following characteristics: ? total volatile organic compounds TVOC 挥发性有机化合物
fformaldehyde HCOH 甲醛
ammonia NH3 氨
carcinogens 一类致癌化合物
odours. 气味

备注:
1.M1、M2、M3标准均按释放量计算,蓝天使与国标按含量计算;
2.VOC:Volatile organic compound,即挥发性有机化合物含量;
3.气味标准即通过随机选取的方式,通过人的嗅觉感受壁纸表面的气味,闻到气味的人数应低于总人数的15%;
4.一类致癌物即对人类有确认的致癌性的化合物。
