9、odies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental a
10、nd non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are
11、described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives. Attention is drawn t

This International Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the
17、user to consult the relevant safety and health regulations, determine the applicability of regulatory limitations, and establish appropriate safety and health practices prior to use. 1 Scope This International Standard specifies required characteristics and additional information to be supplied to t
18、he purchaser by the vendor of those products commonly referred to as liquefied petroleum gases (see ISO 8216-3) and is intended to apply to international transfers of commercial propane and commercial butane. This International Standard is neither intended nor expected to replace or encroach upon na
19、tional standards of any country, since each country is subject to different regulations, codes, industry practices and market utilization. NOTE National standards and safety codes might be applicable when formulating any characteristics required for specific uses. 2 Normative references The followin

33、Table 1 contain a statement of the precision, i.e. the repeatability and reproducibility, to be expected from them but, in cases of dispute, the procedure described in ISO 4259, which uses precision data in the interpretation of test results, shall be used. 5 Documentation The documentation supplied
34、 to the purchaser by the vendor shall include at least the following: a) a reference to this International Standard; b) the type of liquefied petroleum gas supplied, i.e. commercial propane or commercial butane; c) the brand name of the product; d) the ISO designation code, i.e. ISO-F-LP or ISO-F-LB
35、 (see ISO 8216-3); e) the suppliers production code and the date of production; f) precautionary and safety advice. If a transportable container is supplied with the liquefied petroleum gas, it shall also be clearly marked with this information. 6 Sampling A representative sample of non-refrigerated
36、 commercial butane or commercial propane shall be taken in accordance with the procedure given in ISO 4257. For refrigerated liquefied petroleum gases, a sampling procedure shall be agreed between the parties concerned. NOTE Proper sampling of the liquefied petroleum gases is extremely important if
37、the test results are to be significant. ISO 2013 All rights reserved 3BS ISO 9162:2013ISO 9162:2013(E) Annex A (informative) Evaporation residue of liquefied petroleum gases Liquefied petroleum gases may contain trace amounts of non-volatile residues. These contaminants can include a variety of hydr
38、ocarbons derived from the distillation process, compressor lubricating oils, valve greases, and rubber and elastomer extenders from hoses. In the majority of applications, the liquid is evaporated and the fuel is fed to the appliance in the gaseous phase. In those cases where the natural evaporation
39、 capacity of the storage tank is not sufficient to provide the required quantity of gas, vaporizers are widely used. In this case, excessive non-volatile residues can be very detrimental. A distinction can be made between industrial and automotive vaporizers and a variety of energy sources may be ap
40、plied. Automotive vaporizers use, in the majority of installations, the engine coolant as a heat source. With the engine fully warmed up, the coolant will have a temperature of about 80 C to 100 C. Taking this temperature into account as well as the more complicated construction of the automotive va
41、porizer/pressure regulator relative to the industrial installation, it can be concluded that the automotive equipment is the most sensitive with respect to the content of residual matter.4 ISO 2013 All rights reservedBS ISO 9162:2013BS ISO 9162:2013ISO 9162:2013(E) ISO 2013 All rights reserved ICS 7
