This document describes the requirements for and methods of testing of organic linings which are applied to concrete process engineering equipment that will come in contact with aggressive chemical substances (liquids, solids and gases). The requirements specified here may be used for the purposes of quality control (e.g. as agreed between the contract partners).
The standard applies to linings which serve one or more of the following purposes:
- to protect the component from damaging effects of aggressive substances;
- to protect waters (e.g. ground water) from harmful substances;
- to protect the charge from becoming contaminated by components released from the substrate material;
- to achieve a particular surface quality.
The different lining systems are:
a) bonded linings;
b) mechanically fixed linings;
c) loose linings of sheeting material;
d) loose linings of pre-formed pieces or lining units.
Handling of aggressive or water pollutant materials is understood to include
e) storage;
f) filling;
g) loading and unloading;
h) manufacture;
i) treatment;
j) use.
