Principles of method if other than guideline:
The physical state and the odor tests we carried out by subjective assessment.
The physical test has been performed as follows:
A small quantity of atrazine technical was evenly distributed onto a watch glass and the physical state observed at 20°C.
The odour test has been performed as follows:
Atrazine (technical) contained in a glass jar exposed to the atmosphere at 20°C. A current of air was created across the open neck of the jar by light waving of the hand. this air was carefully smelt.
GLP compliance:
yes

solid
Form / colour / odour
Form:
powder
Colour:
Atrtazine (technical) was seen to be bright white with a 90% reflectance equivalent to a N 9.5/white on the neutral scale of the Munsell Book of Color. the appaerance of the test compound was compared to the Munsell neutral value scale.
Odour:
