6、E) 3 Foreword This European Standard (EN 12691:2006) has been prepared by Technical Committee CEN/TC 254 “Flexible sheets for waterproofing”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text o
7、r by endorsement, at the latest by September 2006, and conflicting national standards shall be withdrawn at the latest by September 2006. This European Standard supersedes EN 12691:2001. In order to receive more precise test results a revision of the test procedure was necessary. According to the CE
8、N/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg
9、, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 12691:2006 (E) 4 Introduction This European Standard is intended for characterisation and classification of bitumen, plastic and rubber sheets as manufactured or supplied be
10、fore use. This test method relates exclusively to products or to their components where appropriate, and not to waterproofing membrane systems composed of such products and installed in the works. This test is intended to be used in conjunction with European Standards “Definitions and characteristic
11、s” for bitumen sheets and for plastic and rubber sheets for roof waterproofing. EN 12691:2006 (E) 5 1 Scope This European Standard specifies a test for puncture by impact on sheets for roof waterproofing. Mechanical stress on waterproofing sheets ranges from static long-term loads to dynamic short-t
12、erm loads. This method represents the dynamic category of load where puncture may be caused by impact. This European Standard may also be applied for other purposes of waterproofing. 2 Normative references The following referenced documents are indispensable for the application of this European Stan

14、01, Flexible sheets for waterproofing Bitumen, plastic and rubber sheets for roof waterproofing Rules for sampling 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 top surface upper side of the sheet as used in-situ. It is usually the
15、 inside of the roll. 4 Principle The 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 if required additionally on a soft support (method B). After the impact the test specimen is te
16、sted for leakage. 5 Apparatus The testing is performed using a test apparatus, which enables vertically falling of the drop mass and consists of the parts indicated in 5.1 to 5.7 and can be used with a hard support (method A) or a soft support (method B). 5.1 Stand The stand can be constructed for f
17、ree 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). An example for a guide rail for the falling drop mass is given in Figure 1. EN 12691:2006 (E) 6 Dimen

The weig
19、ht 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 specifications: formed in steel material and firmly fixed to the drop mass; hardened to 50 HRC; spherical forme
20、d 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. 5.3 Release mechanism Release mechanism (trigger) with a setting device for variable drop height from 200 mm to at least 2 000 mm in increments of: 50 mm between 200 mm and 500 mm; 1
21、00 mm between 500 mm and 1 000 mm; 250 mm for drop heights above 1 000 mm. The drop height is measured from the bottom of the puncturing tool to the surface of the test specimen.
