1 Scope This part of GB/T 8570 specifies two methods for the determination of the oil content not volatile at about 105 ℃, of liquefied anhydrous ammonia, namely gravimetric method and infra-red method. When the oil content determined via gravimetric method is less than 5 mg/kg, “less than 5 mg/kg” shall be reported as the determination result, or it shall be determined via infra-red method. 2 Normative References The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of GB/T 8570.
