This Standard specifies the measuring method of absolute vapour pressure at 37.8 \u00b0C of volatile and non-viscous petroleum products in accordance with the Reid method.<\/p>\n
\nFor petroleum products containing oxygenated hydrocarbons covered by this Standard, the maximum concentration of ethers containing 5 or more carbon atoms is 15 %, and for ethanol, 10 %, and for alcohols containing 3 or more carbon atoms, 7 %.<\/p>\n
\nWhen applying this test method to volatile crude petroleum with a vapour pressure exceeding 10 kPa, the precision in clause 13 can not be applied.<\/p>\n
\nFour procedures are described in this Standard.<\/p>\n
\nProcedures A and B are for crude petroleum and petroleum products, excluding aviation gasolines, with a vapour pressure up to 180 kPa, Procedure C is applied to petroleum products with a vapour pressure above 180 kPa, and Procedure D applies to aviation gasolines with a maximum vapour pressure of 50 kPa.<\/p>\n
\nNOTE 1 For all the test methods contained in JIS K 2258 series, see Annex JA.<\/p>\n
\nNOTE 2 For product samples containing methanol or those containing oxygenated hydrocarbons exceeding the limits given in the above scope, the method described in JIS K 2258-2 can be applied.<\/p>\n
\nFor liquefied petroleum gas, the method described in JIS K 2240 can be applied.<\/p>\n
