This Part is Part 9 of GB/T 328.
This Part is identical to "Flexible sheets for waterproofing. Determination of tensile
properties. Plastic and rubber sheets for roof waterproofing" (EN 12311-2.2000).
Chapter and article numbers of this Part are consistent with those of EN
12311-2.2000.
For convenience of use, the main differences between this Part EN 12311-2.2000 are
as follows.
a) "This European Standard" was changed into "this Part";
b) "EN 1849-2", "EN 13416", "ISO 37", " ISO 7500-1" was changed into "GB/T
328.5", “GB/T 328.1”, “GB/T 528” , “JJG 139” respectively;
c) The foreword of EN 12311-2.2000 was deleted; the foreword of this Part was
re-prepared;
d) "Test Methods for Asphalt Waterproof Roll Roofing" (GB/T 328-1989) is replaced
by "Test Methods for Building Sheets for Waterproofing" (GB/T
328.1~328.27-2007) that is consisted of this Part and other parts.
This Part was proposed by China Building Material Industry Association.
This Part shall be under the jurisdiction of the National Technical Committee on
Test methods for building sheets for waterproofing -
Part 9. Plastic and rubber sheets for waterproofing -
Tensile properties
1 Scope
This part of GB/T 328 specifies test methods for the determination of the tensile
properties of plastic and rubber sheets for roof waterproofing.
Method A (ISO 1421) is applicable to all materials; for materials that are not applicable
to Method A, if there is no break on the material, Method B (GB/T 528) may be used to
determine the tensile property.
2 Normative References
The following normative documents contain provisions which, through reference in
this text, constitute provisions of this Part of GB/T 328. For dated references, then
subsequent amendments revisions of these publications do not apply. However,
parties who enter into an agreement based on this Part are encouraged to investigate
the possibility of applying the most recent editions of the normative documents
indicated below. For undated references, the latest edition of the normative document
referred to applies.
GB/T 328.1 "Test methods for building sheets for waterproofing - Part 1. Bitumen
plastic and rubber sheets for waterproofing rules for sampling"
GB/T 328.5 "Test methods for building sheets for waterproofing - Part 5. Plastic
and rubber sheets for waterproofing-thickness and mass per unit area"
GB/T 528 "Rubber, vulcanized or thermoplastic - Determination of tensile stress -
Strain properties"( GB/T 528-1998 eqv ISO 37.1994)
JJG 139-1999 "Verification Regulation of Universal Tension and Compression
Testing Machine"
ISO 1421 "Rubber-or plastics-coated fabrics - Determination of tensile strength
and elongation at break"
3 Terms and Definitions
For the purposes of GB/T 328, the following terms and definitions apply.
3.1 top surface
Upper side of the sheet, as used in situ. This is usually the inside of the roll.
3.2 maximum tensile force
The largest value of tensile force recorded during testing.
3.3 elongation at maximum tensile force
Elongation of the test specimen at the maximum tensile force.
3.4 elongation at break
Elongation of the test specimen at rupture.
4 Principle
A test specimen is stretched at a constant speed until it ruptures. The force and
elongation is continuously recorded throughout the test, and preferably with a
permanent record of the maximum tensile force.
5 Apparatus
Tensile testing machine equipped with a continuous recording of force and
corresponding elongation, and capable of maintaining a uniform speed of grip
separation as specified below.
The tensile testing machine shall have a sufficient loading capacity of at least 2000 N
and a grip separation speed of (100 ± 10 and 500 ± 50) mm/min. The width of grips
shall not be less than 50 mm.
The tensile testing machine shall be equipped with grips of a type which maintain or
increase the clamping pressure as a function of the increase of the tensile force
applied to the test specimen. The test specimen shall be held so that it does not slip in
the grips more than 1 mm for products up to and including 3 mm thick, and 2 mm for
thicker products. A mark or tape on the test specimen where it enters the grips will
help reveal any slip.
