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.

minimum value of displacement in mm; fmax maximum value of displacement in mm. 5.2.4 Acceptance factor k1 The basis for the k1 value is the assumption of a random test with an unknown standard deviation of the result. The acceptance factor k1 shall be taken from Table 6. k1 depends on the number n of test samples (common practice n = 10). The minimum number of n is 3. Consequently

For n = 10 test pieces, the prevailing k1 value is 2,57. 6 Assessment and verification of constancy of performance - AVCP 6.1 General The compliance of metal framing components with the requirements of this standard and with the performances declared by the manufacturer in the DoP shall be demonstrated by: — Determination of the product type; — Factory Production Control by the manufacturer, including product assessment. The manufacturer shall always retain the overall control and shall have the necessary means to take responsibility for the conformity of the product with its declared performance(s). 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 manufacturer. 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 manufacturer for at least 10 years. SIST EN 14195:2015
Sampling procedure for testing A.1 General The required number of samples to determine the compliance with specification should be sampled from a delivery consignment of metal framing components. The appropriate consignment size shall be agreed between representatives of any involved parties who should have the opportunity to be present at the time of sampling. A.2 Sampling procedure A.2.1 General The choice of the method of sampling should be as defined in A.2.2 and A.2.3. A.2.2 Random sampling1) Whenever possible, the random sampling method should be used, in which every metal component in the consignment has an equal chance of being selected for the sample. Three metal components of each type should be selected from positions throughout the consignment without any consideration given to their condition or quality. A.2.3 Representative sampling When random sampling is impracticable or not convenient, e.g. when the metal components form a large stack or stacks with ready access to only a limited number of components, a representative sampling procedure should be used. A.2.4 Sampling from a stack A.2.4.1 General The consignment should be divided into at least three real or imaginary parts, each of a similar size. One component should be selected at random from within each part in order to give the required number of samples as indicated in 5.1. NOTE It will be necessary to remove some parts of the stack or stacks in order to gain access to components within the body of such stacks when taking samples.
1) In practice, random sampling is normally only convenient either when the components forming the consignment are being moved in a loose (unpacked) form from one place to another of when they have been split into a large number of small stacks awaiting installation. SIST EN 14195:2015
Calculation of section properties B.1 Scope This annex provides the rules for the calculation of section properties of metal framing components for use in situations where the stress in the metal is such that there is no need for reduction of effective section area (e.g. assessment of assembly stiffness at low load level). An alternative solution is to use EN 1993-1-3. B.2 Principles a) The thickness used in calculation is the minimum steel core thickness. This is calculated as nominal thickness (see 4.5.2) minus tolerance and thickness
