  • The oxidizing agent is air with an oxygen content of 20.95 % by volume. In the data base it is usually not specified as mixture component. Exceptions are highlighted.
  • Pressure values are absolute, not gauge pressures.
  • Impurities can strongly influence characteristic safety data, particulary if the properties of the impurity considerably deviate from the respective properties of the pure substance.
  • Safety characteristics are only displayed if evaluated data are available.
  • Values can be cited by using the UTI number of the table (Uniform Table Identifier).
  • Color Codes:         recommended value             no recommendation               do not use value
