If applicable, name of local government involved (Articles 3.2 and 7.2):           
2. Agency responsible:   Bureau of Product Standards, Department of  Trade and Industry
Name and address (including telephone and fax numbers, e-mail and web-site
addresses, if available) of  agency or authority designated to handle comments
regarding the notification shall be indicated if different from above:           
3. Notified under Article 2.9.2 [ X], 2.10.1 [    ], 5.6.2 [    ], 5.7.1 [    ], other:           
4. Products covered (HS or CCCN where applicable, otherwise national tariff heading.
ICS numbers may be provided in addition, where applicable):   Unplasticized poly
(vinyl chloride) (ICS 140.30; 93.140)
5. Title, number of pages and language(s) of the notified document:   DPNS 1952:2002 –
Plastics piping systems for non-pressure underground drainage and sewerage –
Unplasticized poly(vinyl chloride) (PVC-U) (15 pages, English)
6. Description of content:   This standard specifies the requirements for pipes with
elastomeric sealing joints for outside diam eters from 110 mm to 1000 mm and with solvent
cement type joint for outside diameters from110 mm to 400 mm and the system of
unplasticized poly(vinyl chloride)(PVC-U) pi ping system in the field of non-pressure
underground drainage and sewerage for the transportation of soil and waste discharge of
domestic and industrial origin, and surface water.
It covers buried pipework but does not apply to piping system buried within the building
structure.
In the case of industrial discharges, chemical and temperature resistance have to be taken
into account.
It also specifies the test parameters for the test methods referred to in this standard.  This
standard is applicable to PVC-U pipes withou t a socket as well as pipes with an integral
socket.
7. Objective and rationale, including the na ture of urgent problems where applicable:
