(OP)
Hi is there anyone who has a copy of the BS 3505, DIN 8062 - ISO 161/1 for uPVC pipes? I would appreciate very much any help and suggestions thanks

Class C - 9 bar
Class D - 12 bar
Class E - 15 bar
There is no Class 10 within BS3505:1986 so I guess that I either have an old copy, it is a class in a different standard, or it is a class given within a particular type of specification.
The current standard I believe is BS EN 1452:2000 which is in 5 parts. Part 1 General, Part 2 Pipes, Part 3 Fittings, Part 4 Valves and Ancillaries, Part 5 Fitness for Purpose. There is a Pipe Series 10 in Part 2 (it specifies pipe based on nominal pressure PN and series S)which is rated to 10 bar for diameters less than 90mm and 12.5 bar for diameters greater than 90mm.
BS3505 was generally replaced by UK water companies with a preference for WIS-31-06 which has two pressure classifications Nominal 8 bar and Nominal 12.5 bar. But I think this has also been superseded.

In EN 1452 the nominal pressure is dependent on the diameter of the pipe and the pipe series. Table A.1 states:
Diameter Nominal Pressure
Nominal Pipe Series
dn S20 S16.7 S16 S12.5 S10 S8 S6.3 S5
<=90 -- (PN6) PN6 PN8 PN10 PN12.5 PN16 PN20
>90 PN6 (PN7.5) PN8 PN10 PN12.5 PN16 PN20 PN25
You should maybe get your company to invest in a copy.

At temperatures below 5C PVC-U has reduced fracture toughness.
