Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part

1.Structure and Drafting Rules of Standardization Documents" drafted. This document replaces GB/T 11132-2008 "Fluorescent Indicator Adsorption Method for Determination of Hydrocarbons in Liquid Petroleum Products", and GB/T 11132- Compared with.2008, except for structural adjustment and editorial changes, the main technical changes are as follows:

--- Deleted the chapter "Meaning and Use" (see Chapter 5 of the.2008 edition);

--- Added an optional adsorption column pressure gas interface connection and schematic diagram (see

5.1.4 and Figure 2);

--- Delete the fixing method of the adsorption column at the end of the ruler (see

10.2 of the.2008 edition);

--- Change the determination of the pH value of silica gel to the footnote of the table (see Table 2,

7.1 of the.2008 edition);

--- Added calculation instructions for samples containing oxygenates (see 10.2);

--- Increased the content of the sample report containing oxygenated compounds (see 11.2);

--- Changed the applicable sample range in Table 3 and Table 4 on the precision (see Note in Table 3, Note 1 in Table 4,

1.4 of the.2008 edition);

--- Changed the applicable content range of hydrocarbons in Table 4 (see Table 4, Table 4 of the.2008 edition). Please note that some content of this document may be patented.

1 Scope

GB/T 11132-2022 is the Chinese national standard on test method for hydrocarbon types in liquid petroleum products - fluorescent indicator adsorption, in the field of petroleum and related technologies. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 12 October 2022 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 12 October 2022. Classification: ICS 75.080, CCS E30. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.
