- Scope
- This standard specifies the classification and severity classification of corrosive and corrosive environmental conditions that industrial automation instruments are subjected to during operation, during installation but not operation, and during storage and transportation. When certain environmental conditions cannot be classified quantitatively, their characteristics are represented by qualitative descriptions. Corrosion and erosion environmental conditions are classified as: non-solid matter, solid matter, flora and fauna. Non-solid chemically active contaminants mainly produce corrosive effects. Solid contaminants may cause erosion, corrosion, thermal and electromagnetic effects. Plants and animals can also have corrosion and erosion effects. Appendix A (the suggested appendix) lists common contaminants associated with various manufacturing plants. This standard is applicable to instrument product design and standard formulation, and provides a basis for selecting test conditions for formulating product evaluation specifications.
