| Nosaukums | This European Standard specifies a quick method for determining, by evaporation, the water content of cationic bituminous road emulsions, with or without polymer added. For bituminous emulsions without flux oil, bituminous emulsions containing vegetal flux oil, and bituminous emulsions containing up to 1,5 % mass of mineral flux oil in the emulsion, this European Standard, according to the selected operating conditions, is considered as an alternative method to the reference method EN 1428 [1]. Above a mineral flux oil content of 1,5 % by mass, depending on the volatility of the flux oil : - the present method can be used up to a flux oil content above 1,5 % by mass if the user can prove its reliability in comparison to EN 1428. - the present method can only be used by correcting the result by means of a previously established correlation with the reference method EN 1428. Polymer modified emulsions may behave differently in the test than unmodified emulsions and the method should be checked against EN 1428 in case of doubt. In case of dispute, determine the water content according to EN 1428. WARNING - The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For environmental reasons and to reduce emissions to air, water and soil, it is recommended that the use of products, solvents and energy should be limited to the minimum required for a valid test result. |
