CHEMICAL RESISTANCE CLASSIFICATION TABLES
The chemical resistance of the plastics are shown
on the tables referring TS 11448 Standards.
Plastics Classification:
LDPE: Low
Density Polyethylene
HDPE: High
density Polyethylene
PP: Polypropylene
PVC-U: Unplasticised
Polyvinylchloride
PEX: Cross-linked
Polyethylene
Symbols and Definitions:
D: "
Resistant" . The material is not negatively
affected ;
- If no internal pressure is applied.
- When used with chemicals with pre-described concentrations,
under pre-described temperatures.
- When there is no external mechanical enforcement.
SD: "Limited
Resistance" The material can be corroded
limitedly though;
- If no internal pressure is applied.
- When used with chemicals with pre-described concentrations,
under pre-described temperatures.
- When there is no external mechanical enforcement.
Therefore the pipes marked with SD should only
be used for projects that a little amount of corrosion
can be tolerated.
DZ: "
Irresistant" The material marked with "IR"
should not be used with chemicals neither pressurized
nor non-pressurized applications because of high
effect rate of chemicals.
