guideline study without detailed documentation
Qualifier:
according to guideline
Guideline:
EU Method A.3 (Relative Density)

Specific details on test material used for the study:
A sample of the test substance was received from Fratelli Lamberti SpA on 11 January 1988, and assigned the Brixham code number R024.
The test substance was a brown vitreous solid. It is made up of a mixture of homologues of the same basic composition, (CI3H1602)n,n<5.

Temp.:
20 °C
Conclusions:
The relative density of Article A has been determined at a temperature of 20°C (D20/4) as 1.12 using a capillary stoppered density bottle method and complies with the test requirements as described in the Official Journal, Test A3. The density was measured by displacement, using an immersion liquid in which Article A is insoluble ((1%) . As Article A is soluble at a much lower level than this in water, (data from Sponsor), water, with 1% surfactant present to ensure adequate wetting of the particles of Article A was used.
