1 This document establishes general principles for the execution of micropiles. They are for: — drilled micropiles a shaft diameter not greater than 300 mm; — driven micropiles a shaft diameter or a maximum shaft cross sectional extension not greater than 150 mm. 2 Micropiles are structural members to transfer actions to the ground and may contain bearing elements to transfer directly or indirectly loads and or to limit deformations. Their shaft and base resistance may be improved (mostly by grouting) and they may be constructed with (see Figure 1): — uniform cross section (straight shaft); or — telescopically changing shaft dimensions; — shaft enlargements; and/or — base enlargement. 3 Other than practical considerations, there are no limitations regarding, length, rake (definition of rake, see Figure 2), slenderness ratio or shaft and base enlargements. 4 The provisions of the document apply to (see Figure 3): — single micropiles; — micropile groups; — reticulated micropiles; — micropile walls. 5 The micropiles which are the subject of this document can be installed into the ground using drilling, driving or a combination of these methods. 6 The material of micropiles covered by this document can be: — steel or other reinforcement materials; — grout, mortar or concrete; — a combination of above. 7 Micropiles may be used for: — working under restricted access and/or headroom conditions; — foundations of new structures (particularly in very heterogeneous soil or rock formations); — reinforcing or strengthening of existing structures to increase the capacity to transfer load to depth with acceptable load settlement characteristics, e.g. underpinning works; — reducing settlements and/or displacements; — forming a retaining wall; — reinforcing of soil to form a bearing and/or retaining structure; — improving slope stability; — securing against uplift; — other applications where micropile techniques are appropriate. 8 Mixed-in-place columns and timber piles are not included in this document. Columns constructed by jet grouting are covered by EN 12716. Ground anchors are covered by EN 1537.

This standard specifies test methods for determining some mechanical properties of commercial wood-based panel products for use in load-bearing timber structures. These properties are intended for the calculation of characteristic values for use in obtaining material design values. For each type and grade of load-bearing panel product, as defined in the Harmonised Standard for wood-based panels (EN 13986), it is necessary to determine characteristic values of mechanical properties to enable it to be used for structural purposes. This standard details the testing required to establish characteristic values. The tests need only be carried out once for each product, unless there is a reason to suspect a significant change has occurred in the properties of the product.#,,#

These methods determine the compressive strength of structural panels in response to stresses acting in the plane of the panel. Method A8212;This method is applicable to structural panels of uniform properties within a panel. It is useful for evaluating plywood of clear, straight-grained veneers, and determining the effect of chemical or preservative treatments, construction, principal direction with respect to direction of stress, and other variables that are expected to uniformly influence the panel. Method B: The compressive properties obtained by this method are a reliable approximation of the strength of a full-size panel, and are intended for use in design. The compressive properties are influenced by buckling; however, this effect can be eliminated in this test by restraining the edges of the specimens. It is recommended that where comparisons are to be made, that the same method and specimen size be used throughout. This is because the volume of material included in a test specimen can influence the compressive strength regardless of whether the material properties are uniform throughout the sheet or vary widely due to the presence of growth or manufacturing features.1.1 These test methods cover the determination of the compression properties of wood-based structural panels. Wood-based structural panels in use include plywood, waferboard, oriented strand board, and composites of veneer and of wood-based layers. 1.2 Method A, Compression Test for Small Specimens8212;This method is applicable to small specimens that are uniform with respect to elastic and strength properties. Two types of compression tests are employed: one to evaluate both elastic and compressive strength properties, and the second to evaluate maximum compressive strength only. 1.3 Method B, Compression Test for Large Specimens8212;This method employs large specimens and responds well to manufacturing variables and growth characteristics that influence compression properties of structural panels. 1.3.1 This method is intended for the following: 1.3.1.1 Comparative tests of structural panels, 1.3.1.2 Evaluating the effects of moisture content on strength properties of structural panels, 1.3.1.3 Determining the strength properties of structural panels, and 1.3.1.4 Evaluating the effects of raw material and manufacturing variables on compression properties of structural panels. 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use.

This standard gives a method for determining characteristic values of mechanical properties and density, for defined populations of timber of visual and/or mechanical strength grades. A method is also given for checking the strength of a timber sample against its designated value. The values determined in accordance with this standard for mechanical properties and density are suitable for assigning grades and species to the strength classes of EN 338. NOTE For assigning grades and species to the strength classes in EN 338 only three characteristic values, i.e. bending strength, mean modulus of elasticity parallel to grain and density need to be determined, other properties may be taken from the table in EN 338.
