5. Title, number of pages and langua ge(s) of the notified document:  Draft Philippine 
National Standard (DPNS) 1950:  2010 – Plastics piping systems for soil and waste discharge (low and high temperature) inside buildings – Unplasticized poly (vinyl chloride) (PVC-U)     
6. Description of content:  This notification specifies the requirements for pipes and the 
system of unplasticized poly(vinyl chloride) (P VC-U) solid wall piping systems in the field 
of soil and waste discharge (low and high temperature) inside buildings.  
It also specifies the test paramete rs for the test methods referred to in this standard.  This is 
applicable to PVC-U pipes, th eir joints intended to be used for soil and waste discharge 
pipework for the conveyance of domestic wast e waters (low and high temperature); for 
ventilation pipework associated with and for rainwater pipework inside the building. 
7. Objective and rationale, including the natu re of urgent problems where applicable:
