Foreword
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 22053-2008 “Pentane vesicant”. Compared with
GB/T 22053-2008, in addition to editorial modifications, the main changes in
content in this Standard are as follows:
- deleted models of F0, F1, F2, F9, F10 (see Table 1 of this Edition, Table 1 of
Edition 2008);
- changed the adjustment range of the component content of each model
from ±5% to ±2%; changed the total mass fraction of pentane from ≥98%
to ≥99%; changed the mass fraction of heavy components C6 and above
from ≤1% to ≤0.5%; changed the sulfur content from ≤10µg/mL to ≤5mg/kg;
changed the evaporation residue from ≤10mg/100mL to ≤1mg/100mL;
added the mass fraction of light component C4 and below, cyclopentane
mass fraction, 2.2-dimethylpropane mass fraction, moisture index; deleted
indexes of mechanical impurities and moisture, copper corrosion and
water-soluble acid or alkali (see Table 2 of this Edition, Table 2 of Edition
2008);
- modified the test method for component content from SY/T 0542 to SH/T
0714, SH/T 1790; modified the test method for density from GB/T 1884 to
GB/T 2013; added SH/T 0689 to the test method for sulfur content; added
SH/T 0246 to the test method for moisture; modified the test method for
bromine index from GB/T 11136 to SH/T 0630, SH/T 1551 (see Table 2 of
this Edition, Clause 4 of Edition 2008);
- deleted type inspection; modified exit-factory inspection items (see 5.1 of
this Edition, 5.1 of Edition 2008);
- modified sampling from SY/T 0543 to GB/T 4756 (see 5.3 of this Edition,
5.3 of Edition 2008).

5 Inspection rules
5.1 Exit-factory inspection
All items listed in Table 2 are exit-factory inspection items.
5.2 Batching
Under the condition of the same raw materials and process, each can of the
product is a batch.
5.3 Sampling
According to GB/T 4756.
5.4 Determination
