3 Classification and marking
3.1 Product classification
This standard is divided into 3 varieties, according to the composition and volatility of
LPG: Commercial propane (used when high volatility is required), commercial butane
(used when low volatility is required), commercial propane-butane mixture (used when
medium volatility is required).
Sampling shall be carried out in accordance with SH/T 0233. The sampling amount
shall meet the required quantity for the exit-factory inspection or type inspection items.
5.4 Judgment rules
If the exit-factory inspection results meet the technical requirements in Chapter 4, the
batch of products is judged to be qualified.
5.5 Re-inspection rules
If the exit-factory inspection results do not meet the technical requirements in Table 1,
re-take double amount of sample from the same batch of products, according to SH/T
0233, to carry out re-inspection of the unqualified items. If the re-inspection results still
do not meet the technical requirements of Table 1, the batch of products is judged to be
unqualified.
6 Marking, packaging, transportation, storage
6.1 According to GB 12268, liquefied petroleum gas belongs to the flammable gas of
category 2, item 2.1 of hazardous chemicals; its hazard marking is carried out according
to GB 13690 and GB 190.
6.2 The liquefied petroleum gas storage tank shall be located in the storage tank area.
Liquefied petroleum gas storage sites shall meet the requirements of GB 50016 and GB
50028. It shall be equipped with eye-catching signs, such as "flammable products, no
fire".
6.3 LPG shall be stored in LPG storage tanks or special cylinders for LPG. The design,
manufacture, use, maintenance of liquefied petroleum gas storage tanks shall comply
with the provisions of GB 150, meanwhile meet the requirements of the "Regulations
on Safety Technical Supervision of Stationary Pressure Vessel". The storage of liquefied
petroleum gas shall comply with the requirements of the "Regulations on Safety
Supervision of Gas Cylinder" and the requirements of GB 5842. Fill cylinders
according to the requirements of GB 14193; overfilling is strictly prohibited.
6.4 When liquefied petroleum gas is transported by railway tanker, car tanker or special
ship, in addition to the implementation of the "Regulations on Safety Supervision of
Special Equipment", railway tanker transportation shall comply with the requirements
of the "Regulations on Safety Management for Liquefied Gas Railway Tanker"; car
tanker transportation shall comply with the requirements of the "Regulations on Safety
Supervision of Liquefied Gas Car Tankers"; the transportation of steel cylinders shall
comply with the requirements of the "Regulations on Safety Supervision of Gas
Cylinders". Ship transportation shall comply with the provisions of GB 18180.
7 Handover acceptance
7.1 Handover
7.1.1 The receiving and delivery organizations or transportation department shall ensure
the supply of clean and compliant car tankers, railway tankers or ships; conduct
