- 20 °C
Any other information on results incl. tables
Tests were carried out at temperatures 20oC. Clean and dry pycnometer together with stopper and cap was weighed in laboratory scale to the nearest 0.0001 g. Next, the pycnometer was filled with Standard Water of purity 3, thermostated to test temperature (20oC). After measuring the temperature using a thermometer, the pycnometer was dried, cooled and weighted. To determine the weight of Mecoprop-K, the pycnometer was emptied of water, dried, filled with tested material, thermostated and was weighed after drying and cooling. According to the applied norm if the difference of results is less than 0.03 g/ml then two trials are enough.
Applicant's summary and conclusion
- Executive summary:
- Density of tested material at 20oC, as the mean of two trials, rounded to tree decimal places is 1.172 g/ml.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
