25、s European Standard is intended for characterization and classification of bitumen, plastic and rubber sheets as manufactured or supplied before use. This test method relates exclusively to products or to their components where appropriate, and not to waterproofing membrane systems composed of such
26、products and installed in the works.This test is intended to be used in conjunction with European Standards “Definitions and characteristics” for bitumen sheets and for plastic and rubber sheets for roof waterproofing.6BS EN 12691:2018EN 12691:2018 (E)1 ScopeThis European Standard specifies a test f
27、or puncture by impact on sheets for roof waterproofing. Mechanical stress on waterproofing sheets ranges from static long-term loads to dynamic short-term loads. This method represents the dynamic category of load where puncture may be caused by impact.This European Standard may also be applied for
28、other purposes of waterproofing.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

31、 and definitions apply.3.1top surfaceupper side of the sheet as used in-situNOTE It is usually the inside of the roll.4 PrincipleThe test specimen is struck on the top surface of the sheet by a free falling drop mass with a puncturing tool.The test specimen is lying on a hard support (method A) and
32、if required additionally on a soft support (method B). After the impact, the test specimen is tested for leakage.5 Apparatus5.1 GeneralThe testing is performed using a test apparatus, which enables vertically falling of the drop mass and consists of the parts indicated in 5.2 to 5.8 and can be used
33、with a hard support (method A) or a soft support (method B).5.2 StandThe stand can be constructed for free falling of the drop mass or optionally for rail guided falling and should be at least as long (high) as the maximum drop height to be tested (for most practical purposes 2 m will be sufficient)

The weight of the drop mass including the puncturing tool shall be (500 5) g; the diameter should be preferable between 25 mm to 30 mm.The puncturing tool shall be made according to the following speci
36、fications: formed in steel material and firmly fixed to the drop mass; hardened to 50 HRC; spherical formed with a diameter of (12,7 0,1) mm; shaft diameter of (10 0,1) mm; shaft length about 40 mm.See example in Figure 2.5.4 Release mechanismRelease mechanism (trigger) with a setting device for var

The diameter of the remaining impact in the plate is 3,4 0,2 mm after the puncturing tool dropped from 500 mm direct on the plate without a

46、ositions across the width and the length of the roll excluding 100 mm at the edges.The test specimen shall be cleaned on both sides with filter paper to remove adhered solid remnants and surface dirt.The test specimens shall be conditioned for at least 24 h at the specified test condition.11BS EN 12
47、691:2018EN 12691:2018 (E)8 ProcedureTesting is carried out at a temperature of (23 2) C.For testing, the test specimens shall be placed on the support with the top surface upwards and pressed down by the ballast ring.The test is performed by releasing the drop mass from the drop height to be tested.
48、 The puncturing tool shall hit the centre of the test specimen in the middle of the ballast ring.Preliminary tests can be made to indicate a drop height around which perforation could be expected by increasing/reducing the drop height until perforation is noticed/avoided (increments of drop height s
49、ee 5.4).For every test a new test specimen shall be used and the support shall not be exposed to impact at the same point more than once.That requires for each impact for: method A: to move the aluminium plate for about 25 mm; method B: to move the polystyrene panel for about 50 mm.The main test with one impact on five different test specimens shall not result in more than one puncture. If more than one puncture occurs, the drop height shall be reduced until further impact on five different test specimens does not result i
