FLEXIBLE SHEETS FOR WATERPROOFING -BITUMEN, PLASTIC AND RUBBER SHEETS FOR ROOF WATERPROOFING -
Rules for sampling
1 2 EN 1850-1 1 Scope
This European Standard specifies the general rules how to select the samples of bitumen, plastic or rubber sheets for roof waterpoofing from which the test pieces are taken. It also specifies the conditioning procedures to be followed before the test piece is cut from the sample.
This standard is appliable in conjunction with product characteristics on bitumen; plastic and rubber sheets for roof waterproofing from which the test specimens are taken.
2 Normative references
This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).

1 3.1 3.2 3.3 For the purpose of this European Standard, the following terms and definitions apply.
3.1 consignment
batch or delivery of roofing sheets which are tested
3.2 sample
roll of a flexible sheet from which a test piece is taken
3.3 sampling
procedure used to select or to constitute a sample from a consignment for third party testing in accordance with Figure 1

3.4 3.5 3.6 3.7 4 5 part of the sample from which test specimens are taken
3.5 test specimen
piece of accurate dimensions taken from test piece
3.6 longitudinal direction
direction in the plane of the sheet parallel to the axis of manufacture
3.7 transversal direction
direction in the plane of the sheet at right angles to the axis of manufacture
4 Principle
The method describes the sequence of actions which to be followed to produce test pieces and test specimens.
5 Sampling
The sampling should be agreed by the parties involved. In absence of such an agreement it can be carried out as indicated in Table 1.

6.1 Temperature conditioning
The sample(s) shall be stored for at least 24 h at (20 6.2 Test pieces
Unroll the selected sample(s) on a flat surface and cut off a test piece over the full width and of a suitable length to allow the required test specimens to be cut.
6.3 7 а?) Ь?) с?) d) The outer turn of the roll shall be rejected unless protected by suitable wrapping.
The test piece shall be marked to Identify the material, the top surface of the sheet and the direction of manufacture. The test piece shall be stored for at least 20 h at (23 6.3 Test specimens
Before cutting the test specimens the test piece shall be inspected; the test piece shall show no signs of creasing as a consequence of the sampling procedure or transportation and it shall be ensured that the test piece is free of any visible defects in accordance with EN 1850-1 or prEN 1850-2:2000 respectively.
Cut test specimens in accordance to the procedure, specified in the relevant European Standards for flexible sheets for roof waterproofing depending on the properties to be determined and the required number of test specimens.
The test specimens shall be marked to identify the material, the top surface of the sheet and the direction of manufacture.
7 Sampling report
The sampling report shall contain at least the following information:
a) all details necessary to identity the product tested in accordance with the European Standard on flexible sheets for waterproofing;
b) a reference to this European Standard (EN 13416) and any deviation from it;
c) any signs of creasing or any defects, which are a consequence of the production or conditioning process;
d) date and place of sampling.
