a.TCO’99 随着TCO 的认证的升级,1998年底开始提供认证的TCO’99提出了更为严格的标准,于显示器而言提出了画面质量的相关要求,并列显示性能做了一些规范性的工作,如最大亮度,均习性等指标等。由于该认证在TCO’95的严格的生态标准基础之上提出了更高的要求,如产品原料及制造过程中不能含有对人体神经系统及胚胎组织有害的重金属元素(如汞、镉等)以及化合物(如有氯,溴的阻燃材料等),产品必须利于回收,制造厂商也必须提出一套环保计划来配合执行。从TCO’95开始, 环保及对人体无害方面就已经成为TCO 认证的长项,开始受到如欧盟等重视环保的国家青睐的标准,甚至成为产品的市场准入标准之一。
