The test shall be conducted using the open spot test method and 100 hours exposure to a 30 per cent sulphuric acid solution (battery acid with a specific gravity of 1,219) and 24 hours exposure to a polyalkalene glycol, e.g. brake fluid.

In the iron and steel, refining, inorganic chemical (sulphuric acid and nitric acid) and paper pulping sectors virtually all plants are large point sources and expected to be for the foreseeable future.

Nevertheless, the Commission analyzed in detail those markets where the merger could have implications from a competition point of view, i.e. certain chemical intermediates such as Chlor-Alkali, Mono Chloro Acetic acid, Ethylene Diamines, polymer chemicals, pulp and paper chemicals and surfactants.

Therefore laboratory glassware coming into contact with aqueous solutions of aflatoxins should be soaked in dilute acid (e.g. sulfuric acid = 2 mol/l) for several hours, then rinsed well with distilled water to remove all traces of acid (e.g. three times, check with pH-paper).
