EN 14195:2005 (E) 10 4.6 Calculation of section properties Where users find it necessary or are required to predict the performance of the installed section, this can be undertaken by calculation using, as a basis, the mechanical properties of the metal framing component. In order to ensure that this can be done producers shall provide the necessary material properties and, where required, the calculation shall be made in accordance with the methods/principles given in Annex B. 5 Test methods 5.1 Sampling Three sections of each type, thickness and profile shall be tested. 5.2 Measurement of dimensions 5.2.1 Principle Thickness, length, angular dimensions, straightness, twist, section width and flange width shall be measured. 5.2.2 Apparatus a) A continuously flat surface capable of taking the longest section having a level of L/1000. b) A micrometer permitting a reading to 0,01 mm. c) A metal rule permitting a reading to 1 mm. d) A metal tape measure permitting a reading to 1 mm. e) A protractor with revolving arm permitting a reading to 1° (see Figure 2). f) A slide calliper permitting a reading to 0,1 mm. g) Hand vice or weight. 5.2.3 Procedure 5.2.3.1 Thickness Measure the thickness with the micrometer in three separate positions on a representative surface area free from profile and any distortions from cutting. Record the results for thickness to the nearest 0,01 mm. 5.2.3.2 Length Place the specimen on the flat surface and measure the length along the web using the metal tape measure. Record the results for length to the nearest 1 mm. 5.2.3.3 Angular dimension Place the base of the protractor on one surface ensuring that it is in direct contact with the plane of the surface and registers it correctly. Move the protractor close to the angle and rotate the arm until it is in firm contact with the adjacent flange. Read off the angle shown on the protractor (see Figure 2). Record the results for angular dimension to the nearest degree.

Figure 2 — Revolving arm protractor for accurate measurement of angles 5.2.3.4 Straightness Place the specimen on the flat surface and use the metal rule to measure the maximum deviation from the plane of the flat surface. Rotate the specimen through 90° about its longitudinal axis and repeat the measurement. Record the results for straightness to the nearest 1,0 mm. 5.2.3.5 Web width of section Place the specimen on the flat surface with the web uppermost.
Select three positions not closer than 150 mm from the end of the section. Using the slide calliper measure the specimen on the outside in the position shown in the diagram (see Figures 3, 4 and 5). The measurements shall be taken as close to the bends as possible. Record the results for width to the nearest 1 mm.

EN 14195:2005 (E) 13 5.2.3.7 Measurement of twist of section Place the specimen on the flat surface, web down. Press the end against the surface, using the hand vice or weight, in such a way that there is full contact between the web and the surface. At a distance 2 500 mm from the secured end of the specimen, measure the gap h using the metal rule (see Figure 7). When the length of the section is less than 2 500 mm the gap should be measured at the end of the section and calculated proportionately to an equivalent length of 2 500 mm. Calculate the twist as h/W where h is the gap and W is the nominal width of the section.
Figure 7 — Measurement of twist of section 6 Evaluation of conformity 6.1 General The compliance of metal framing components with the requirements of this document and with the stated values (including classes) shall be demonstrated by: Initial Type Testing (ITT); Factory Production Control by the producer (FPC). For the purposes of testing, metal framing components may be grouped into families, where it is considered that the selected property is common to all metal framing components within that family. The decision on those products or properties which fall within a family shall be made by the producer. 6.2 Type testing 6.2.1 General Sampling and testing shall be in accordance with Clause 5. The results of all type tests shall be recorded and held by the producer for at least 5 years. 6.2.2 Initial type testing Initial type testing shall be performed to show conformity with this document.
Initial type testing shall be performed at the beginning of the production of a new metal framing components type (unless it is a member of a family previously tested) or at the beginning of a new method of production (where this may significantly affect the stated properties).
EN 14195:2005 (E) 14 Tests previously performed in accordance with the provisions of this standard (same product, same characteristic(s), test method, sampling procedure, system of attestation of conformity, etc.) may be taken into account. All product characteristics in Clause 4 applicable to the intended uses shall be subject to initial type testing, with the following exceptions: release of dangerous substances may be assessed indirectly by controlling the content of the substance concerned; when design values or declared values are used; when reaction to fire is class A.1 (no contribution to fire) without further testing as 4.1. 6.2.3 Further type testing Whenever a change occurs in the m
