GB/T 25993-2010 in English

《GB/T 25993-2010透水路面砖和透水路面板》由TC285（全国墙体屋面及道路用建筑材料标准化技术委员会）归口，主管部门为中国建筑材料联合会。

1 Scope

This standard specifies the terms and definitions, format, classification and marking, general requirements, technical requirements, test method, inspection rules, product conformity certificate, stacking and delivery for permeable paving bricks and permeable paving flags.
This standard is applicable to permeable paving bricks and permeable paving flags (hereinafter referred to as "permeable blocks") with satisfactory permeability for uses such as municipal pedestrian, garden footpath and non-heavy loaded pavements.
Permeable blocks may be made from non-reinforced cement concrete by forming processes such as vibration and compression or mainly from inorganic nonmetallic materials such as coal gangue, ceramic and pottery waste, and clay by sintering process.
