Foreword

GB/T 3146 "Industrial Aromatic Hydrocarbons and Related Materials distillation range of measurement" is divided into two parts. --- Part 1. distillation; --- Part 2. Chromatography. This section GB/T 3146 Part 1. This section uses redrafted law revision by the United States Society for Testing and Materials standard ASTMD850-03 (2008) ε1 "Aromatic and Industrial Related materials Determination of distillation range. " This portion ASTMD850-03 (2008) ε1 have more adjustments in the structure, listed in Appendix A of this section and ASTMD850-03 (2008) reg number of control list ε1. This portion ASTMD850-03 (2008) ε1 technical differences and their reasons are as follows. --- For Chapter 2, "Normative references" in this section have been adjusted technical differences, in order to adapt to China's technical conditions, with Body adjusted as follows. 1) with the GB/T 4756 instead of ASTMD3437; 2) with GB/T 6536-1997 instead of ASTME133; 3) with GB/T 8170 instead of ASTME29; 4) Remove the ASTMD4790; 5) Remove the ASTME691; 6) increase the GB/T 16483; --- For more standardized definitions of terms to facilitate understanding of the method of this section to increase the initial boiling point (3.1) In Chapter 3, the decomposition point (3.2), dry point (3.3) and end point (3.4) of the terms and definitions, and ASTMD850-03 (2008) ε1 12.2 and 12.3 Scale is defined in relation to an increase in distillate content in this chapter as a distillation range (3.5) terms and definitions; --- In order to meet our standards, this section will ASTMD850-03 (2008) ε1 in Chapter 5, "meaning and purpose" for content For the "Introduction"; --- This section in accordance with China's national conditions, deleted ASTMD850-03 (2008) ε1 in 6.6.1 use gaslights heating distillation the way; --- Because our current product standards xylene report final boiling point, increased this section 9.1.4 regarding the "9.1 Manual Distillation Procedure" Observe the final boiling point of content; --- This section increases the precision of the xylene in the final boiling point of 12.2, due to our existing product standards xylene report final boiling point; --- In order to meet our standards, this section deleted ASTMD850-03 (2008) ε1 in Chapter 15 Categories of content; --- In order to facilitate check, this part of the increase in Appendix B, given the changes in atmospheric pressure thermometer calibration values. This section also made the following editorial changes. --- Removed ASTMD850-03 (2008) ε1 about 1.2 units instructions to meet our standards. This Part replaces GB/T 3146-1982 "Determination of distillation range benzene products" in the distillation. This section compared with GB/T 3146-1982 The main changes are as follows. --- In order to maintain consistency with the ASTMD850-03 (2008) ε1 name, and in accordance with sub-section of the standard name of the rules for preparation, This part of the name from "benzene products Determination of distillation range" to "Industrial Aromatic Hydrocarbons and Related Materials Determination of distillation range - Part 1. Steam Distillate Law "; --- This section in Chapter 2, supplemented with the appropriate normative references; --- This part of the increase in Chapter 3, "Terms and Definitions", Chapter 6, "hazard", Chapter 13, "quality control" of the content; --- This part of the GB/T 3146-1982 3.1 in the sampling process has been modified in this section in Chapter 7 requires the removal of the free Water is not allowed to remove dissolved water, no longer predetermined sample temperature; --- This part of the increase in Chapter 5 of the automatic distillation unit, the distillation can be automatically measured, precision automatic methods benzene is not given; --- Remove the GB/T 3146-1982 Chapter 1 Content "instrument" in this part of GB/T 6536-1997 distillation apparatus, temperature Meter using indexing is 0.2 ℃ industrial aromatics distillation thermometer or equivalent ASTM thermometer, a receiver to Normal Cylinder; --- Revised GB/T 3146-1982 of 4.6 Thermometer calibration method, eliminating exposed thermometers, in this part of Chapter 10 Thermometers were calibrated itself and atmospheric pressure on the thermometer calibration, and increased joint optional thermometer with atmospheric pressure calibration; --- In this section 9.1.3 in the test procedure end point of observation methods were modified by the addition of dry observation point and the decomposition point And content of the report, by deleting the GB/T 3146-1982 4.4 The end point is defined; --- In order to maintain and ASTMD850-03 (2008) Consistency ε1 precision, accuracy This section has been modified, deleted GB/T 3146-1982 repetitive content in 12.1.1 and 12.2.1 introduced intermediate precision; --- Since the GB/T 3146-1982 distillation and chromatography is divided into two parts, this section deleted GB/T 3146-1982 in color Spectroscopy content; --- In order to facilitate comparison and calculation Now, this part of the increase of Appendices A and B, are informative appendices. This part is proposed by the China Petroleum and Chemical Corporation. This part of the National Standardization Technical Committee on Petroleum Products Lubricants oil and lubricants and fuels Technical Committee (SAC / TC280/SC1) centralized. This section drafted by. China Petroleum and Chemical Corporation Jinling Branch. The main drafters of this section. Fang Hong, Chen Guanrong, Li line, Jin Wu, Cai Mei, Zhou Ying. This part of the standard replaces the previous editions are. --- GB/T 3146-1982.

Introduction

This section applies to the development of product specifications, can also be used as internal quality control tool, but can also be used to open aromatics industry and related materials Hair or development work.
