SAMPLE SOLUTION

Time (mins)	Reading (mN/m)	Temperature (°C)
115 125 135 157 169	63.3 63.5 63.8 63.3 63.6	27.0 27.5 27.5 27.5 27.5

 

Mean reading = 63.5 mN/m

Surface tension = reading x calibration factor

                       = 63.5 x 1.003

                       = 63.7 mN/m

Conclusions:

The surface tension of a 1.01 g/l solution of JPR BLUE 100 (Lot Number 303001) was determined to be 63 .7 mN/m at 27.5 ± 0.5 °C.

Executive summary:

A number of general physico-chemical properties of the compound JPR BLUE 100 (Lot Number 303001) have been determined at the request of the sponsor.

 

The surface tension study complied with Method A5 of Commission Directive 92/69/EEC (which constitutes Annex V of Council Directive 67/548/EEC).

 

The determination was carried out using a surface tensiometer (based on the ISO 304 ring method).

 

The surface tension of a 1.01 g/l solution of JPR BLUE 100 (Lot Number 303001) was determined to be 63 .7 mN/m at 27.5 ± 0.5 °C.
