Safe use, storage, transport and commercial supply of refrigerant gases call for different technical documents. This section explains what SDS/MSDS, TDS, CoA and common quality parameters mean.
Types of technical documents
- SDS / MSDS
- The Safety Data Sheet covering hazards, first aid, fire-fighting, safe use, storage, exposure and transport.
- TDS
- The technical data sheet summarising the product’s main physical and chemical properties and application notes.
- CoA
- The document showing measured analysis results for a given production or filling batch.
- Product specification
- Defines the quality criteria and acceptance limits the product is expected to meet.
- Batch / lot traceability
- Lets a cylinder or pack be linked to the related production or filling batch.
Quality parameters often checked on refrigerant gases
Depending on the product and specification, refrigerant gases may be checked for purity, moisture, acidity, non-condensable gases and residue.
- Purity — the share of the target refrigerant in the product
- Moisture — water that can affect system and oil performance
- Acidity — acidic components that can react with materials and oils
- Non-condensable gases — air and similar gases that can harm system pressure and efficiency
- Residue — non-volatile matter left after the refrigerant evaporates
Safety and transport frameworks
Classification, labelling and transport rules for refrigerant gases can vary by product. Storage and shipping should therefore follow both the SDS and the transport rules in force.
