Administrative data

Endpoint:
flash point of flammable liquids
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the flash point is only relevant to liquids and low melting point solids
Cross-reference
Reason / purpose:
data waiving: supporting information
Reference
Endpoint:
appearance / physical state / colour
Type of information:
experimental study
Adequacy of study:
key study
Study period:
11 October 2017 - 14 February 2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Qualifier:
no guideline followed
Principles of method if other than guideline:
The appearance was determined by visual observation (direct and under a microscope). No guideline was followed for the appearance determination but sufficient details were given in the study report.
GLP compliance:
yes (incl. certificate)
Physical state at 20°C and 1013 hPa:
solid
Key result
Form:
solid: particulate/powder
Colour:
Off white
Odour:
other: not determined
Substance type:
organic

A test substance sample was observed to be a fine and medium off-white powder with clusters. Based on observation with a 3.2 objective lens, the particles appeared to be irregular shaped crystals. Based on observation with a 40 objective lens, the sample was observed to be made up of single crystalline particles.

Conclusions:
The substance is an off-white powder at room temperature.
