EN 384:2016+A2:2022(Main + Amendment)
Structural timber - Determination of characteristic values of mechanical properties and density
SIST EN 384:2016+A2:2022

This European Standard gives a method for determining characteristic values of mechanical properties and density, for defined populations of visual grades and/or strength classes of machine graded structural timber. Additionally it covers the stages of sampling, testing, analysis and presentation of the data.
The standard provides methods to derive strength, stiffness and density properties for structural timber from tests with defect-free specimen.
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 1   For assigning grades and species to the strength classes in EN 338 only three properties, i.e. bending or tension strength, modulus of elasticity parallel to grain in bending or tension and density need to be determined from test data, other properties can be calculated according to Table 2.
NOTE 2   EN 1912 gives examples of established visual grades assigned to strength classes.

SIST EN 14081-1:2016+A1:2019

This European Standard specifies requirements for strength graded structural timber with rectangular cross-sections either visual or machine graded, shaped by sawing, planning or other methods and with cross-sectional dimensions complying with EN 336 (referred to as structural timber in the following clauses).
This European Standard includes provisions for test methods, Assessment and Verification of Constancy of Performance and marking of structural timber.
NOTE 1   For machine strength graded timber additional provisions for type testing (TT) are given in EN 14081-2 and for factory production control (FPC) in EN 14081-3.
NOTE 2   An acceptance procedure for verification of a lot is given in EN 14358 which may be used for a delivery of structural timber.
This European Standard identifies characteristics for which limits have to be given in visual grading standards.
This European Standard covers structural timber, untreated or treated against biological attack.
This European Standard does not cover:
-   timber treated by fire retardant products to improve its fire performance;
-   thermally and/or chemically modified timber;

EN 14358:2016(Main)
Timber structures - Calculation and verification of characteristic values
SIST EN 14358:2016

This standard gives statistical methods for the determination of characteristic values from test results on a sample drawn from a clearly defined reference population of e.g. solid wood, fasteners, connectors and wood-based products. The characteristic value is an estimate of the property of the reference population and can be based on a 5-percentile value of strength, resistance or density as well as on a mean value for stiffness.
Parametric methods are given for the determination of lower and upper 5-percentiles. The upper 5-percentile is the 95-percentile.
This standard is suitable for use with any structural product in the frame of type testing as well as factory production control.
Sampling is not covered by this document, but reference is made to the relevant product standards.
This standard also provides the acceptance procedure for verification of a lot.
Depending on the product, characteristic values determined in accordance with this standard may be used directly or may need additional adjustments specified in the relevant product standards.
Note:   For example, in the case of solid timber, specific adjustment factors for calculation of characteristic values are given in EN 384.

Structural timber - Visual strength grading of tropical hardwood
SIST EN 16737:2016

This European Standard specifies a method of strength grading tropical hardwood visually for structural use.
The permissible limits of characteristics for a single visual strength grade of timber are specified, designated “Structural Tropical Hardwood” (STH) grade.
The method is only suitable for pieces of timber with a rectangular cross-section that is constant along their lengths.
Characteristics related to durability are not covered in this standard. For some end uses, additional requirements may be specified at the time of grading, e.g. sapwood exclusion.

Structural finger jointed solid timber - Performance requirements and minimum production requirements
SIST EN 15497:2014

This European Standard sets out provisions regarding the performance characteristics for structural finger jointed timber with rectangular cross section for use in buildings and bridges.
The use of structural finger jointed timber may be limited to certain service classes in some member states.
It also lays down minimum production provisions and procedures for Assessment and Verification of Constancy of Performance for structural finger jointed timber.
This European Standard is applicable to structural finger jointed timber made of coniferous timber species listed in this standard or poplar.
Although it may be possible to produce structural finger jointed timber made from specific broadleaf species based on some provisions of this European Standard, this standard is not applicable to these products.
This European Standard is only applicable to finger joints between timber sections of the same species.
This European Standard does not cover impressed (die-formed) finger joints.
This European Standard covers structural finger jointed timber untreated or treated against biological attack. Structural finger jointed timber treated with fire retardants is not covered.
