Administrative data

Endpoint:
appearance / physical state / colour
Type of information:
other: The colour and physical state of the substance has been documented in multiple laboratory reports when assessing other physico-chemical properties of the substance. While no specific colour or physical form testing was carried out, but appearance/physical
Adequacy of study:
key study
Study period:
04 June 2003 - 04 july 2003
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
other: Expected to be fully reliable as this was documented in the independent Laboratory reports. Observation used to assess physical form and colour.
