drafting.

This document replaces GB/T 23661-2009 "Structural Rubber Gaskets for Construction". Compared with GB/T 23661-2009, except for structural adjustment

In addition to rectification and editorial changes, the main technical changes are as follows.

a) The classification has been changed (see Chapter 4, 3.1 of the.2009 edition);

b) Increased the ozone resistance performance requirements under the ozone concentration of (50+/-5)x10-8, and will

The ozone resistance performance requirements below are changed to optional requirements (see Table 1, Table 1 of the.2009 edition);

c) Delete the requirements and tests of "lip seal pressure" (see 3.6.5 of the.2009 edition);

d) The requirements and test methods for "clamping force" have been added (see 5.4, 6.4);

e) The requirements and test methods for "water resistance" have been added (see 5.5, 6.5);

d) Replace ISO 3302-1 (see 5.3) with the Chinese document GB/T 3672.1.2002 to adapt to the technical conditions of our country;

e) Deleted 6.1 of ISO 5892.2013 to eliminate meaningless description;

f) Deleted Table 3 of ISO 5892.2013, because its content has been adjusted to 5.4, 5.5, 5.6, 5.7 and Table 1;

g) Replace ISO 7619 (see 6.1.2) with GB/T 531.1 to adapt to the technical conditions of our country;

h) Replace ISO 37 (see 6.1.3) with GB/T 528-2009 to adapt to the technical conditions of our country;

i) Replace ISO 815-1 (see 6.1.4) with GB/T 7759.1-2015 to adapt to the technical conditions of our country;

j) Replace ISO 815-2 (see 6.1.4) with GB/T 7759.2-2014 to adapt to the technical conditions of our country;

k) Replace ISO 188 (see 6.1.5) with GB/T 3512 to adapt to the technical conditions of our country;

l) Replace ISO 1431-1 (see 6.1.6) with GB/T 7762-2014 to adapt to the technical conditions of our country;

m) Replace ISO 812 (see 6.1.7) with GB/T 15256-2014 to adapt to the technical conditions of our country;

n) The test method for dimension measurement has been added---measuring according to GB/T 2941 (see 6.3) to improve operability;

o) The flame retardant performance test method and GB/T 10707-2008 (see 6.6) are added to improve operability;

p) Replace ISO 3865 (see 6.7) with GB/T 19243 to adapt to the technical conditions of our country.

q) The chapter "Inspection Rules" (see Chapter 7) has been added to adapt to the technical conditions of our country;

r) The chapter "Signs, packaging, transportation and storage" (see Chapter 8) has been added to adapt to the technical conditions of our country.

The following editorial changes have been made to this document.

--- Changed the chapter title of the type from "operating temperature range" to "classification" (see Chapter 4) to express it more accurately;
