4. Products covered (HS or CCCN where applic able, otherwise national tariff heading. 
ICS numbers may be provided in addition, where applicable):    
Unplasticized poly (vinyl chloride) pipes  (ICS:  23.040.20) 
5. Title, number of pages and language(s) of the notified document:   Draft Philippine 
National Standards 1952:2005 – Pipes for Non-Pressure Underground Drainage and 
Sewerage -Unplasticized Poly (vinyl chlo ride) (PVC-U) (17 pages, in English) 
6. Description of content:   This notification specifies the requirements for unplasticized poly 
(vinyl chloride) (PVC-U) pipes and piping systems intended for solid wall single layer for 
use for non-pressure underground drainage and sewerage for the conveyance of soil and 
waste discharge of domestic and industr ial origin, as well as surface water. 
It covers buried pipework but does not apply to piping systems buried within the building 
structure. 
In the case of industrial discharge, the chemical and temperature resistance have to be taken  
into account but this will have  to be done separately. 
This standard is applicable to PVC-U pi pes with or without an integral socket. 
This standard also specifies the test paramete rs for the test methods referred to herein.  
It does not cover requirements for the K-value of the raw material. 
7. Objective and rationale, including the na ture of urgent problems where applicable:
