3 Terms and Definitions

ISO 3405 and ISO 4626 to establish the terms and definitions of the following terms and definitions apply to this standard. 3.1 When distillation under standard conditions, when the temperature first drops of condensate from the condenser when the fall (by correcting when necessary). 3.2 Under standard conditions Sample distillation to a maximum temperature of the final stage (by the correction if necessary). 3.3 Distillation under standard conditions, the evaporation temperature of the bottom of the flask when the last drop of liquid (if necessary, by correcting). 3.4 Initial boiling point and dry point temperature range. Principle 4 For testing purposes, the distillation is carried out under narrowly defined circumstances. 4.1 standard temperature and condensate volume corresponding to test products; except between the condensate temperature difference between the two kinds of volume only for the regulation Given the nature of the product in preparation (calibration temperature as a function of volume), otherwise the temperature should be corrected in accordance with the provisions of Chapter 9; or 4.2 When the thermometer shows the temperature of each of distillation, according to the provisions of Chapter 9 is previously adjusted temperature, the present standard for testing products on the condensate Volume Detailed provisions (nominal volume as a function of temperature).
