Notes:

  1. The mass fraction of propane and propylene at the manufacturer's agreement with the consumer is not less than 60% for gas of the grade SPBT.
  2. When the mass fraction of mercaptan sulfur in liquefied gas is not less than 0.002%, it is allowed not to determine the intensity of the odor. If the mass fraction of mercaptan sulfur is less than 0.002%, or the intensity of the odor is less than 3, the liquefied gases must be odorized according to the procedure approved in the established order.
