10、word This document has been prepared by Working Committee NA 054-04-03 AA Baubahnen of the Normenaus-schuss Kunststoffe (Plastics Standards Committee). The withdrawal of DIN 16726:1986-12 titled “Plastic roofing felt and waterproofing sheet Testing” was initiated in 2007 because the coexistence phas
11、e for work on waterproofing sheeting at European level was coming to an end. However, several national rules still refer to the national standard and so a decision was made to publish a new edition of DIN 16726 as a “residual standard”. As a “residual standard” the present document contains the rema
12、ining test methods which have not been standardized at European level, giving the specifications originally laid down in DIN 16726:1986-12. For the test methods that have been specified at European level in the meantime, the relevant clause or subclause of this document only refers to the European S
13、tandard in question. The original structure of DIN 16726:1986-12 (order and numbering of clauses and subclauses) has been maintained. Annex A gives an overview of the correlation between the old and new test methods. The present document is to be seen as a temporary solution which will help users ma
14、ke the transition to the use of the European test methods. In case of doubt the test methods standardized at European level are to be given priority. The tests laid down in EN 13956 and in European testing standards do not always correspond in detail to the tests originally specified in DIN 16726:19
15、86-12, but nevertheless deliver comparable results. Therefore, additional conditions are to be applied by analogy. The requirements of the old national product standards that have also been withdrawn (DIN 16729, DIN 16730, DIN 16731, DIN 16732-1, DIN 16732-2, DIN 16734, DIN 16735, DIN 16736, DIN 169
16、35, DIN 16937, DIN 16938) correspond to the requirements of the current prestandard DIN V 20000-201 “Use of building products in construction works Part 201: Application standard for waterproofing sheet according to European product standards for use as waterproofing of roofs”. Amendments This stand
17、ard differs from DIN 16726:1986-12 as follows: a) the title of the standard has been changed; b) the scope has been changed to encompass the testing of plastics sheeting and film; c) for tests which are to be carried out in accordance with European Standards a reference has been made to the relevant
18、 European Standard and the headings of the relevant subclauses changed accordingly; d) tests which are not specified in European Standards (adhesion to substrate) and certain steps of testing which have not been standardized at European level have been kept; e) the standard has been editorially revi

NOTE In DIN 16726:1986-12 this term was Flchengewicht in German, while in the present edition the German term flchenbezogene Masse is used. 5.5 Density Density shall be determined in accordanc
36、e with EN ISO 1183-1 or EN ISO 1183-2 or EN ISO 1183-3. 5.6 Tensile properties 5.6.1 Tensile strength Tensile testing shall be carried out in accordance with EN 12311-2. 5.6.2 Elongation Elongation at break shall be determined in accordance with EN 12311-2. 5.7 Joint behaviour 5.7.1 Joint shear resi

38、and the tensile strength as in 5.6.1. NOTE 2 This subclause corresponds to DIN 16726:1986-12, 5.7.1 “Bond strength in longitudinal shear”. 5.7.2 Joint peel resistance The joint peel resistance shall be determined in accordance with EN 12316-2.

41、.1 Shear resistance of joints formed with bitumen 5.10.1.1 Preparation of test pieces Take two 300 mm 400 mm specimens (with the longitudinal side being 300 mm) from the sheet to be tested and condition them for 15 min in an oven at 60 C. Use a doctor blade to apply a 1 mm thick and 100 mm wide laye
42、r of hot bitumen 85/25 at 200 C in the middle of the specimen to be tested (see Figure 1). Then, for “A” test specimens cut off the uncoated part of the sheet at the top, for “B” test specimens cut off the uncoated part of the sheet at the bottom (see Figure 1). Cut the sheet into 50 mm wide longitu
43、dinal strips (see Figure 1); thus, on each strip the bitumen-covered area is 50 mm 100 mm. Place the prepared strips in pairs with the bitumen-covered side facing up for 10 min at 85 C in an oven with forced air circulation and then, for each pair, put one strip on top of the other, with the bitumen
44、-covered areas facing each other (see Figure 2). Make sure they are aligned properly so that the free ends lie in one axis. Then, subject the bonded joint to a force of 20 N (distributed across the entire bonded area) and condition the bonded strips for a further 10 min at 85 C in an oven with force
45、d air circulation.

46、 been prepared as specified in 5.10.1.1, for 24 h in standard atmosphere 23/50, class 2, as in EN ISO 291. Then, determine shear resistance in accordance with EN 12317-2. DIN 16726:2011-01 8 5.10.2 Shear resistance of joints formed with other adhesives 5.10.2.1 Preparation of test pieces Take two 30
47、0 mm 400 mm specimens (with the longitudinal side being 300 mm) from the sheet to be tested and condition them for 15 min in an oven at 60 C. Use a doctor blade to apply a 100 mm wide layer of adhesive, with the required adhesive thickness, in the middle of the specimen to be tested (see Figure 1).
48、The processing instructions for the respective adhesive are to be followed. Then, for “A” test specimens cut off the uncoated part of the sheet at the top, for “B” test specimens cut off the uncoated part of the sheet at the bottom (see Figure 1). Cut the sheet into 50 mm wide longitudinal strips (s
49、ee Figure 1); thus, on each strip the bitumen-covered area is 50 mm 100 mm. Taking the strips in pairs, form an adhesive joint according to the processing instructions for the respective adhesive (see Figure 2). Make sure they are aligned properly so that the free ends lie in one axis. 5.10.2.2 Procedure Before testing, condition the test specimens, which have been prepared as specified in 5.10.2.1, for 24 h in standard atmosphere 23/50, class 2, as in EN ISO 291.
