    Abstract - (Show below) - (Hide below)

    This standard deals with the means to be used to prevent the pollution of potable water inside premises and the general requirements of protection devices to avoid pollution by backflow. The hygiene protection specifications ofthis standard are applicable to all the standards for systems or appliances connected to the private supply system for water intended for human consumption.This standard specifies the minimum requirements for product standards of protection units. The product standards are used to detail product specifications.
