Foreword
This document was drafted in accordance with the rules provided in GB/T 1.1-2020 Directives
for Standardization - Part 1.Rules for the Structure and Drafting of Standardizing Documents.
This document serves as a replacement for GB/T 26127-2010 Compressed Coalbed Methane
as Vehicle Fuel. In comparison with GB/T 26127-2010, apart from structural adjustments and
editorial modifications, the main technical changes are as follows.
a) The scope of application of compressed coalbed methane as vehicle fuel is modified
(see Chapter 1; Chapter 1 of Version 2010);
b) The terms and definitions are modified (see Chapter 3; Chapter 3 of Version 2010);
c) The representation of methane is modified (see Table 1; Table 1 of Version 2010);
d) The quality indicator requirements for high calorific value, total sulfur and water dew
point are modified (see Table 1; Table 1 of Version 2010);
e) The quality requirements for carbon dioxide and particulate matter are added (see
Table 1);
f) The classification indicators for compressed coalbed methane as vehicle fuel are
added (see Table 2);
g) The test method for total sulfur is modified (see 5.4; 5.3 of Version 2010);
h) The test method for hydrogen sulfide is modified (see 5.5; 5.4 of Version 2010);
i) The test method for carbon dioxide is added (see 5.6);
j) The test method for water dew point is modified (see 5.7; 5.5 of Version 2010);
k) The test method for particulate matter is added (see 5.8);
l) The provisions for labeling are deleted (see 7.1 of Version 2010);
m) The provisions for filter element pore size are added (see 7.2);
n) The provisions for storage containers are modified (see 7.3; 7.3 of Version 2010).
