    Important note The composition, procedures and data specified herein are based on general
    application technology checks performed on a laboratory scale in a standard
    climate (23 °C / 50 % r.H.). The suitability of these procedures under modified
    conditions (e. g. increased scale) should therefore be ascertained first. We
    strictly recommend to test the formulation under the conditions of the intended
    use if these conditions vary from the standard climate.
