木地板重金属含量测定标准发布 明年5月1日起实施

  央视新闻客户端10月14日消息,国家标准委昨天发布了“木质地板重金属元素含量测定”等315项国家标准,将于明年陆续实施。

  《木质地板饰面层中重金属元素含量测定》国家标准对木质地板中重金属含量提出了明确的要求,对于保障居室空气安全具有重要意义。

  木材本身并不含有重金属,但经过涂饰、贴面、防腐和阻燃等加工处理后,可能含有铅、镉、汞、铬、砷等重金属。这些重金属可能从表层材料溶出或随着表层材料的脱落被儿童误食,对身体造成危害。

  为了促进木质地板行业健康快速发展,急需制定木质地板饰面层中重金属含量测定标准。《木质地板饰面层中铅、镉、铬、汞重金属元素含量测定》国家标准对于现有的实木地板、实木复合地板、强化地板、PVC饰面地板等地板饰面层中重金属元素总量和可溶性重金属元素含量都提出了指标要求,填补了目前木质地板相关产品理化指标空白,对于提高现有木质地板质量,保障居室空气安全具有重要意义。这一标准预计将于明年5月1日起正式实施。
