Preface
This standard is a revision of GB9052.1--88. Non-equivalent uses ASTMD1835-91&Liquefied Petroleum Gas". This revision mainly has the following changes:
1. The citations have been cleaned up and supplemented, and the latest version has been cited; 2. The product classification of propylene and butane mixtures has been canceled for winter use and summer use: 3. Density has been added to the technical requirements item; oil spill observation has been added to the residue requirements: the allowed calculation methods for density and vapor pressure have been supplemented.
This standard will replace GB9052.188 from the effective date. This standard was proposed by China National Petroleum Corporation. This standard is under the jurisdiction of the Planning and Design Institute of China National Petroleum Corporation. This standard was drafted by: North China Petroleum Exploration and Design Institute of China National Petroleum Corporation. The main drafter of this standard: Li Hengmi.
This standard was first published on April 21, 1988. 17

This standard adopts the following definitions. www.bzxz.net
3.1 Liquefied petroleum gas (LPG) is a liquid petroleum product with propane and butane as the main components. Generally, there are commercial propane, commercial butane and commercial propane and butane mixtures. 3.2 Commercial propane is mainly commercial propane. It is composed of propylene and a small amount of butane and trace ethane, and is suitable for products that require high volatility during use. 3.3 Commercial butane commercial butane is mainly composed of butane, a small amount of propane and a trace amount of pentane. Suitable for products requiring low volatility during use. 3.4 Commercial propane and butane mixtures commercial PBmixtures are mainly composed of propane, butane and a small amount of ethane and pentane, and are suitable for products that require medium volatility during use. Approved by the State Administration of Quality and Technical Supervision on 1998-06-17 1

Visual inspection
4.2 In order to ensure the safe use of liquefied petroleum gas, when the liquefied petroleum gas does not contain detectable odor, mercaptans with obvious odor should be added. Odorants formulated with thioethers or sulfur-containing compounds. 5 Sampling
Liquefied petroleum gas sampling shall be carried out in accordance with SH0233. 6 Testing Rules
6.1 Production Inspection
When one of the following situations occurs, the product shall be comprehensively inspected according to the technical requirements specified in Table 1:) New equipment is put into production or the main process flow, equipment and gas source are changed and When production is resumed after shutdown for maintenance: b) During normal production, regularly or when a certain base (such as a full tank) is accumulated;) When there is a big difference between the factory inspection and the last comprehensive inspection results. 6.2 Factory inspection
The factory inspection of LPG is an inspection carried out when the product is sold and handed over. The following provisions shall be followed: a) When shipping, the supplier shall take samples from the storage tank of the shipped product or the transfer point agreed between the supplier and the buyer, conduct inspections according to components, vapor pressure, density or items specified in the contract, and submit the ex-factory qualification to the buyer. certificate. b) When receiving the goods, the purchaser has the right to randomly inspect the quality of the products received. If it is found that the product does not meet the specified quality standards or contract requirements, it can request re-inspection, retain the samples and analysis results, and ask the arbitration unit for a ruling. 7 Marking, packaging, storage, transportation
