ISO 2878:2017规定了一种测试方法,用于确定全部或部分由橡胶制造的抗静电和导电产品的电阻,该橡胶在新的情况下在限定点之间测量的电阻不超过3 × 108 Ω,并且其导电性来自于向材料主体中添加炭黑和/或其他适当的物质。
注意,高导电性混合物不能以这种方式制备。
ISO 2878:2017规定了基本几何形状的电极配置,但特定产品的要求应参考相关产品规范。
它不适用于:
a)相关表面由绝缘和导电区域的混合物组成的产品;
b)具有大量绝缘材料表面积的产品,鞋类除外(其通常不具有导电或抗静电鞋面)。
ISO 2878:2017 specifies a method of test to determine the electrical resistance of antistatic and conductive products manufactured wholly or in part from rubber whose electrical resistance measured between defined points, when new, does not exceed 3 × 108 Ω and whose conductivity is derived from the addition of carbon black and/or other appropriate substances to the bulk of the material.
NOTE Highly conductive mixes cannot be made in this way.
ISO 2878:2017 specifies the electrode configuration for basic geometries, but it is intended that reference be made to relevant product specifications for requirements for specific products.
It does not apply to:
a) products the relevant surfaces of which are composed of mixtures of insulating and conductive areas;
b) products with a substantial surface area of insulating material, except for footwear (which does not normally have a conductive or antistatic upper).
