### 1,1,3,3•TETRAMETHYLBUTYL PEROXYPIVALATE NOTOX Projec(

SUMMARY The determination of the flash-point of 1,1,3,3-T£TRAMETHYLBUTYL PEROXYPIVALATE was performed using a Pensky-Martens closed cup flash-point apparatas, in accordance with EEC-Directive 92/69 EEC, A.9 'Flash-point"(1992) and DIN £N 22719: "Bestimmung des Fiammpunktes Verfahren nach PenskyMartens im geschlossenen Tiegel'; August 1985. The flash-point of 1,1,3,3-TETRAMETHYLBUTYL PEROXYPIVALATE is <1°C when using a Pensky-Martens closed cup flash-point apparatus.

# n GUIDELINES

The study procedures described in this report are based on the following 

### guidelines: European Economic Community (EEC), EEC-Directive 92169 EEC, Part A,Methods for the determination of physico-chemical properties, A.9 °Flashpoint', EEC Publication No. L383, December 1992. DIN EN 22719: "Bestimmung des Flammpunktes Verfahren nach Pensky-Martens im geschlossenen Tiegel'; August 1985. ARCHIVING NOTOX B.V. wi11 archive the following data for at ieast 10 years: protocol, report, test substance reference sample and raw data. TEST SYSTEM AND RATIONALE ® Test system A Pensky-Martens closed flash-point tester (according to DIN EN 22719). Conditions The apparatus was placed in a fume-cupboard. The window of the cupboard was left open to reduce the draft to a 

### 0 minimum.

Rationale Recognized by the international guidelines as



### recommended test system (EEC, DIN). VALIDATION OF THE TEST PROCEDURE The test procedure as outlined in this report is validated periodically, using p-xylene (zur synthese; Merck, FRG). The results are in accordance with the NOTOX criteria for validation. ~

### 4 i PERFORMANCE OF THE TEST

Preparations The cup of the flash-point apparatus was filled with the sample to be 

## 4 tested to the level indicated by the filling mark. The lid, with a

thermocouple for detection of the flash point and a resistance thermometer for measuring the sample temperature, was placed on the cup. Thereafter, the cup was placed in the heating block. Performance of the test The test substance was heated in the apparatus with a temperature rise of approximately 5-6 0 C/m9n. The samp1e was stirred while being heated. The test flame was applied so that the flame was lowered into the vapour space of the cup in 0.5 s, left in its lowered position for 1 s, and quickly raised to its high position. The sample was not stirred while the test flame was applied. 

### Preliminary test The test substance temperature was 15°C at the start of the test. Starting at 18°C, a test flame was applied at each 2°C temperature rise.
~ 

### Main study

The test substance temperature was 10°C, 3°C and 0°C at the start of test one, two and three, respectively. Starting at 12°C, 4°C and 1°C a test flame was applied at each 1°C

n lJ DATA HANDLING

The flash-point is the lowest temperature at 101.3 kPa, at which the test liquid in a closed test vessel evolves vapours, under the conditions definetl in the test method, in such amount that a flammable vapour(air mixture will be produced in the test vesseT. The (lowest) flash-point temperature was corrected'for the atmospheric pressure. Corrected flash-point = C+ 0.25 (101.3 - p) where: C = (iowest) observed flash-point [°C]

p = ambient barometric pressure [kPa] The corrected flash-point is reported in °C and rounded off to 1°G. RESULTS Preliminary test: Flash-point: i8°C 

### Main study: Table 1: Determined flash-points during the main study. Test number Flash-point

[°C] 

### Lowest Flash-point

[°C] 1 12 1 2 4 3 1 The atmospheric pressure on the day of the test, was 102.0 kPa. The lowest flash-point was corrected for the atmospheric pressure. 

# 11 Corrected flash-point = <1 + 0.25(101.3-102.0)°C

In conclusion, the flash-point of 1,1,3,3-TETRAMETHYLBUTYL PEROXYPIVALATE is <1°C under the conditions of the test. n ..
