- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- GLP compliance:

- Type of method:
- pycnometer method
- Dynamic viscosity of test material:
- The relative density was determined by a pyknometer method. The procedure conformed with EC Directive 92/69/EEC Method A3 and OECD Guideline 109. The following steps were performed with the test substance "as received", and following dilution with distilled water to contain nominally 1% of active ingredient.
A clean, dry pyknometer was weighed empty. It was filled with test substance to the top of the stopper capillary and re-weighed, then after emptying, cleaning and drying, this was repeated using distilled water. These steps were performed with the fluids which had been equilibrated to a test temperature of 20°C. The process was repeated a further three times. - Type:

- Conclusions:
- The relative density of 5-chloro-2-methyl-3(2H)-isothiazolone was determined to be 1.60 (at 20.8°C).
- Executive summary:
The relative densitiy of the test substance 5-chloro-2-methyl-3(2H)-isothiazolone was determined according to OECD guideline 109. A sample of the test compound was weighed, filled into a sample cell connected to a reference cell. The cells were separated, the reference cell filled with helium to overpressure, which was read. The cells were coupled, and the pressure read. The relative density was calculated from the resulting pressure and the weight of test substance sample.
