- Before testing, each aerosol dispenser shall be conditioned and then primed by discharging for approximately one second.
- Alternatively, the normal batch test may be changed into a semi
- In the case of harness belts, the buckle shall be connected to the testing apparatus by the straps which are attached to the buckle and the tongue or two tongues located in an approximately symmetrical way to the geometric centre of the buckle.
- In testing solids, pastes, and particulate substances, the amount used should have a volume of 0,1 ml, or weigh approximately 0,1 g (the weight must always be recorded).
- continuous test, if no degradation of the test substance has been achieved during approximately 60 days of testing using the batch procedure.
- With asynchronous testing the frequencies of the two force components shall be between approximately 1 % and a maximum of 3 % apart.
- Approximately 24 hours before testing, fur should be removed, by clipping or shaving, from the dorsal area of the trunk of the animal. When clipping or shaving the fur, care should be taken to avoid abrading the skin.
- If the humidified NO span gas sample does not pass through a sample dryer for this verification test, the vessel temperature shall be controlled to generate an H2O level approximately equal to the maximum mole fraction of H2O expected during emission testing.
