Determination of volatile residues of fluorinated olefins for refrigerants
General method
1 Scope
This standard specifies the use of dry reduction method for the determination of volatile residues in fluorinated olefins for the general test method of sampling, the original method
Rationale, test method, allowable difference.
This standard applies to the determination of the evaporation residue in fluorinated olefins for refrigerants. The sensitivity of this test method is 0.0001%.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
General rules for sampling of liquid chemical products GB/T 6680-2003
General rules for sampling of gas chemical products GB/T 6681-2003
GB/T 6682 Analytical laboratory water specifications and test methods
3 Principle of the method
The sample was evaporated and the mass of the residue was weighed and the evaporation residue was calculated.
4 sampling
4.1 Instruments and equipment
4.1.1 Sampling cylinders. 1000mL or 500mL single or double valve small cylinders, the working pressure should be greater than the same product pressure.
4.1.2 Sampling Bottle. 1000 mL or 500 mL Milled Glass Bottle.
4.1.3 sampling catheter. copper or iron joints, copper (medium and high pressure), glass tube (low pressure) and so on.
4.2 Operational requirements
4.2.1 The sampling of fluorinated olefins for medium and high pressure refrigerants shall be carried out in accordance with 7.10 of GB/T 6681-2003. Sampling cylinders and
Sampling ducts should be vacuum dried, the sample should be liquid into the sampling cylinder, the total amount of sampling should ensure that the inspection needs.
4.2.2 Sampling of fluorinated olefins for low pressure refrigerants shall be carried out in accordance with 7.1 of GB/T 6680-2003. With a dry sample bottle
Line sampling, the total amount of sampling should ensure the need for inspection.
4.2.3 affixed with the label and specify. product name, batch number, sampling date and sample name, etc., for inspection purposes.
5 test method
WARNING. Some of the test procedures specified in this standard may result in hazardous conditions and appropriate safety and health precautions should be taken by the user.
