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.

and elongation at break"

In the case of sheets with composite reinforcements, which give rise to two or more

distinct peaks on the force/elongation curve, the force and elongation of the two

greatest peaks and also the elongation at break shall be recorded.
