other: Corrected Flash Point

Remarks:

Test 2

Data Evaluation:

The pressure, the uncorrected as well as the corrected flash point is reported. The correction of the flash point to a standard pressure of 101.3 kPa (1013 mbar) is done by the appliance at the following way:

T_C = T₀ + 0.25 × (101.3 – p)

Where:

T_C = flash point corrected to standard pressure of 101.3 kPa (°C)

T₀ = determined flash point at ambient atmospheric pressure (°C)

p = ambient atmospheric pressure during the performance of the test (kPa)

The mean value of corrected flash points T_C of the main tests were calculated and rounded to the nearest 0.5 °C (T_R).  T₀, p, T_C, and T_R are reported.

Results – Preliminary Test:

The approximate flash point of the preliminary test was ~ 100 °C.

Results – Main Test:

Test No.	Pressure (kPa)	flash point measured T0(°C)	flash point corrected TC(°C)	rounded mean flash point^(1)TR(°C)	Maximum allowed deviation from mean^(2)(°C)
1	98.7	101.9	102.6	103.0	± 3.0
2	98.8	103.0	103.6

⁽¹⁾: rounded to the nearest 0.5 °C

Interpretation of results:

GHS criteria not met

Remarks:

Flash point is > 60 °C (the upper temperature limit for flammable liquids Cat according to Regulation (EC) 1272/2008 of 16 December 2008).

Conclusions:

The mean corrected flash point of the test item was determined to be 103.0 °C at 101.3 kPa.

Executive summary:

EU Method A.9. - The flash point of the test item was determined using a non-equilibrium closed cup method.  The procedure employed was designed to be compatible with Method A.9., Flash Point, of Commission Regulation (EC) No 440/2008 of 30 May 2008.

Following a preliminary test to establish an indicative flash point, the flash point apparatus was filled > 50 % and closed.  The test item was stirred at 115 rpm and subject to a programmed temperature increase of 5.5 °C/min.  A first ignition trial was performed 22 °C below the expected flash point.  The ignition source was presented to the test item every 1 °C until a flash point was observed.  This value was corrected to standard pressure and rounded to the nearest 0.5 °C.  This procedure was performed in duplicate.

The flash point of the test item was determined to be 103.0 °C at 1013 hPa.

The test item cannot be categorised in accordance with Commission Regulation (EC) No 1272/2008 (Classification Labelling and Packaging) of 16 December 2008.
