This section identifies physical and chemical properties associated with the substance or mixture. The minimum required information consists of:
|Appearance (physical state, color, etc.)||Upper/lower flammability or explosive limits;|
|Odor threshold||Vapor density|
|Melting point/freezing point||Solubility (ies.)|
|Initial boiling point and boiling range||Partition coefficient: n-octanol/water|
|Flash point||Auto-ignition temperature|
|Evaporation rate||Decomposition temperature|
The SDS may not contain every item on the above list because information may not be relevant or is not available. When this occurs, a notation to that effect must be made for that chemical property. Manufacturers may also add other relevant properties, such as the dust deflagration index (Kst) for combustible dust, used to evaluate a dust’s explosive potential.
