applicable to this document.
3.1 Peel strength
It refers to the force required to peel a unit width of adhesive tape from a specific
adhesive surface at a specified angle and speed, in unit of N/cm.

(suitable when toxicity or flammability restrictions apply).
Solvents shall be of general purpose chemical grade and held in a suitable
vessel.
5.3 Apparatus
5.3.1 Test piece cutter
An appropriate test piece cutter shall hold two single edge razor blades in
parallel planes a precise distance apart, to form a cutter of exact specimen
width; two cutters, 12mm and 24mm cutting widths, shall be available or
appropriate alternatives which will not cause edge damage. The precision of
the razor blade separation shall be the nominal width ± 0.1mm.
5.3.2 Testing machine
A constant rate of extension (CRE) tension tester shall be used. It is proposed
to use an automatic recorder taking at least one reading per mm of the adhesive
tape peeled. The tester shall have two clamps calibrated to the same centerline,
parallel with the direction of the motion on the same plane and so aligned that
they will clamp the specimen wholly. MOVE at a uniform rate of (5.0 ± 0.2) mm/s.
RECORD the load reading. The maximum permissible error shall be 2%.
5.3.3 Stainless steel plates
The surfaces of the stainless steel plates shall be perfectly flat, at least 125mm
long, 50mm wide and 1.1mm thick. Stainless steel types shall comply with the
06Cr19Ni10 material specified in GB/T 3280-2007. The stainless steel plates
(hereinafter referred to as “steel plates”) shall have a bright annealed finish with
a surface roughness (GB/T 2523-2008) of (50 ± 25) nm.
The steel plates showing stains, discoloration or many scratches are not
acceptable. The steel plates shall be cleaned prior to use as described in
Section 5.5.2. The steel plate test surface shall be protected from scratches
and contamination during use, and shall be stored according to the conditions
described in Section 5.4.1.
The standard test conditions are as follows. the ambient temperature shall be
(23 ± 1) °C; the relative humidity shall be (50 ± 5) %.
5.5.2 Preprocessing of the steel plates
5.5.2.1 USE one of the solvents described in Section 5.2.2 to clean the steel
plates. USE fresh absorbent cleaning material to wipe the steel plates to
dryness. REPEAT for a total of three washes with the same solvent. USE methyl
ethyl ketone or acetone for cleaning during the final wipe.
5.5.2.2 After washing, DRY the steel plates for at least 10min. The testing
steel plates that have not been used within 10h need to be cleaned again. In
order to obtain consistent results, USE methyl ethyl ketone or acetone to clean
new steel plates for at least 10 times before use.
Note. DISCARD the steel plates with stains, discoloration or many scratches. AVOID contacting the
surfaces of the steel plates with fingers. During storage, the steel plates shall be protected from
damage or contamination.
5.5.3 Sample preparation and test for the peel strength
5.5.3.1 Sample preparation
As described in Section 5.4.4, CUT a 300mm long test piece from the adhesive
tape to be tested. FOLD 12mm at one end, adhesive surface to adhesive
surface to form a tab. TOUCH the other end of the test piece to an end of the
steel plate. HOLD the tabbed end of the test piece so that it does not make
contact with the steel plate, but is positioned loosely above it. ROLL
mechanically or by hand twice in each lengthwise direction, so as to prevent
entrapment of air between adhesive surface and steel plate. Should this occur,
DISCARD the test piece, and MAKE preparation again.
Individually PREPARE each test piece. TEST within 1min.
Note. Peel strength increases with the dwell time of various adhesive tapes. If it is necessary to select
longer dwell time, MAKE further indications.
5.5.3.2 Peel strength test
PEEL 25mm of the adhesive tape from the steel plate at the folded end of the
adhesive tape. CLAMP one end of the steel plate into one of the jaws of the
tensile testing machine. CLAMP the free end of the adhesive tape into the other
jaw. CONDUCT continuous peeling at the rate of (5.0 ± 0.2) mm/s.
After the load jaw is in operation, DISREGARD the values obtained while the

Foreword
This standard equivalently adopts the to the part 8. 180° adhesion test method
of JIS Z 0237-1991 Pressure-sensitive adhesive tape test method.
1. Differences between this standard and part 8 of JIS Z 0237.
(1) JIS Z 0237 specifies that the material of the test plate is SUS 304, which
is the domestic brand Cr18Ni9. This standard specifies that the material
of the test plate is 0Cr18Ni9 or 1Crl8Ni9Ti.
(2) JIS Z 0237 does not clearly specify the preparation of double-sided
pressure-sensitive adhesive tape specimen.
2. This standard mainly revises the following contents of GB/T 2792-1981.
(1) ADD the specimen preparation and test of double-sided pressure-
sensitive adhesive tapes.
(2) ADD the specifications for the material of test plates.
(3) ADD the treatment of the surface of the test plate and test plate cleaning
before the test.
(4) CHANGE the hardness of the roller wrapping rubber (Shore A) from 60°
± 5° to 80° ± 5°.
This standard will replace GB/T 2792-1981 as of the date of implementation.
