"Pydraul A-200" Spraying test on a flame A sample of the hydraulic fluid trade marked "Pydraul A-200" was submitted to the test mine by Firma W. Ktihnk, Hamburg. This hydraulic fluid Is essentially a chlorinated phosphate ester. The technological properties of the fluid were established by Technlschen Uberwachungsverein Essen e.V. through chemical-physical analyses. The report was conducted on September 27, 1963* In accordance with the "Second Report of the European Association for Coal and Steel, of March 8, 1963". Illustration 1 shows the test equipment. The fluid to be tested, which had a temperature of 65 + 5C* was compressed by means of nitrogen, with a pressure oT 70 + 3 kp/cm2, through a nozzle with a bore diameter of 0.4 mm. The spray jet thus produced was directed on a metal screen at a distance of 1.75 m. In the spray stream, there was a flame from an oxyethylene torch (tip of the torch 750 l/h) whose inner white, blue rimmed cone was 10 cm long, horizontal, wa3 directed at right angles to the spray jet, so that the nozzle moved along from the nozzle to a distance of 120 cm from the latter to the shaft of the spray cone, at the rate of 4 cm/s. The flame remained for 5 s at the point of the greatest distance from the nozzle. Illustrations 2, 3 and 4 show the effects of the hydraulic fluid on the flame at distances of 0.4 m, 0.8 m and 1.2 m. The spray jet ignited, without the flame reaching the screen. Therewith, the requirements set forth in the above mentioned "Second Report1) (page 27) were fulfilled. Dortmund, January 29, 1964.

G/Z Test Report On combustion experiments on the Hydraulic Fluid "Pydraul 625" - Spraying test on a flame. A sample of Hydraulic Fluid was submitted to the test mine by Firma W. Ktihnk, Hamburg. This hydraulic fluid is essentially a chlorinated phosphate ester. The technological properties of the fluid were determined by means of a chemical-physical analyses, made by Technischen Nberwachungsvereln Essen e.V. The test was conducted on November 23, 1963, according to the "Second Report of the European Association for Coal and Steel of March 8, 1963". The test equipment is shown in illustration 1. The fluid to be tested, which had a tem perature of 65 + 5C, was compressed by means of nitrogen with a pressure of 70 + 3 kp/cm2 through a nozzle with a bore diameter of 0.4 mm. The spray jet thus produced was directed on a metal screen placed at a distance of 1.75 m from the nozzle. In the spray jet there was the flame from an oxyacetylene-torch (mouthpiece 750 l/h) whose inner white, blue bordered blowing pin was 10 cm long, horizontal, was guided at right angles to the spray jet In such manner, that the cone tip moved along from the nozzle to a distance of 120 cm from it on the shaft of the spray cone, at the rate of 4 cm/s. The flame remained 5 s on the point of the greatest distance from the nozzle. Illustrations 2, 3 and 4 show the effect of the hydraulic fluid on the flame at distances of 0.4 m, 0.8 m and 1.2 m. The spray jet Ignited, without the flame reaching the screen. Therewith, the requirements set forth in the above mentioned "Second Report" (page 27) were fulfilled.
