⚙️ Testing and Compliance
The properties specified must be determined using the referenced ASTM test methods. Sampling should be performed per Practice E300. The distillation range at 760 mmHg ensures purity, with an initial boiling point of at least 85°C and a dry point not exceeding 90°C. Water content is limited to 0.2% by weight to guarantee heptane miscibility without turbidity.
⚠️ Important: For hazard information, refer to the supplier’s Material Safety Data Sheet (MSDS). Conformance to specification limits requires rounding off observed values to the nearest unit in the last digit of the specification limit, in accordance with Practice E29.
This standard references Guide D268 for sampling and testing of volatile solvents. Although some listed standards have been withdrawn, they remain applicable for this specification. For the latest versions, consult the ASTM website.
