POLYPERINY

Boiling point

Administrative data

Endpoint:

boiling point

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance is a solid which decomposes before boiling

Cross-reference

Reason / purpose for cross-reference:

data waiving: supporting information

Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

1996-04-24 - 1996-08-15 (experimental phase)

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

guideline study

Qualifier:

according to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Version / remarks:

EEC Directive 92/69, Part A, Methods for the determination of physico-chemical properties, A.1 "Melting/Freezing temperature", EEC Publication No. L383, December 1992.

Deviations:

no

GLP compliance:

yes (incl. QA statement)

Type of method:

capillary method

Specific details on test material used for the study:

- Storage condition of test material: at room temperature (at about 20 °C)

Key result

Decomposition:

yes

Decomp. temp.:

>= 274.85 °C

Conclusions:

Polyperin Y has been determined to decompose from 548 ± 0.5 K prior to melting.

Executive summary:

The determination of the melting point / melting range of the test item was performed according to the EEC Directive 92/69, A.1 "Melting/Freezing temperature", December 1992 ; (which constitutes Annex V of Council Directive 67/548/EEC) under GLP. The determination was carried out using the capillary method/melting temperature devices with liquid bath.

Polyperin Y has been determined to decompose from 548 ± 0.5 K (274.85 °C) prior to melting.
