目前,鉴于石棉对人体有害的议论,日本石棉瓦等建材业界开始正式推行“非石棉化”的政策。“石棉瓦协会”制定出具体目标为:(1)硅酸钙板至1991年末完全“非石棉化”;(2)挠性板至1991年末石棉含有量限制在5%以下:(3)波形石棉板至1993年末石棉含有量限制在5%以下。
At present, given the argument that asbestos is harmful to the human body, the building materials industry in Japan, including asbestos and tile, has officially adopted the “non-asbestos” policy. The specific objectives of the “Asbestos Tile Association” are as follows: (1) The calcium silicate board is completely “non-asbestos” by the end of 1991; (2) The amount of asbestos contained in the flexible board until the end of 1991 is limited to 5% or less: (3) Waveforms The asbestos board limits the asbestos content to less than 5% by the end of 1993.
