Timber structures - Strength graded structural timber with round cross-section - Requirements
prEN 14544

This European Standard lays down the requirements for visual graded structural timber with round cross-sections, barked of unbarked and cut on length but otherwise not machined.
This standard specifies tolerances on sizes and identifies the characteristics for which, as a minimum, limits shall be given in visual grading rules. It also proposes two grades recommended where no national grades exist.
Structural timber treated against fire or biological attack is not covered in this standard.

Structural timber - Determination of characteristic values of mechanical properties and density
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.

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;
-   structural finger jointed timber.

Round and sawn timber - Environmental Product Declarations - Product category rules for wood and wood-based products for use in construction
EN 16485:2014

This European Standard provides general Product Category Rules (PCR) for Type III environmental declarations for wood and wood-based products for use in construction and related construction and in-service processes.
This European Standard complements the core rules for the product category of construction products as defined in EN 15804 and is intended to be used in conjunction with EN 15804.
NOTE    The assessment of social and economic performances at product level is not covered by this standard.
The core PCR:
—   define the parameters to be declared and the way in which they are collated and reported;
—   describe which stages of a product’s life cycle are considered in the EPD and which processes are to be included in the life cycle stages;
—   define rules for the development of scenarios;
—   include the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the specification of the data quality to be applied;
—   include the rules for reporting predetermined, environmental and health information, that is not covered by LCA for a product, construction process and construction service where necessary;
—   define the conditions under which construction products can be compared based on the information provided by EPD.
For the EPD of construction services, the same rules and requirements apply as for the EPD of construction products.
Additionally to the common parts of EN 15804, this European Standard for wood and wood-based products:
—   defines the system boundaries;
—   defines the rules for modelling and assessment of material-specific characteristics such as carbon storage and energy content of wood;
—   defines allocation procedures for multi-output processes along the wood chain;
—   defines allocation procedures for reuse, recycling and energy recovery;
—   includes the rules for calculating the Life Cycle Inventory and the Life Cycle Impact Assessment underlying the EPD, including the assessment of carbon and energy content of wood;
—    provides guidance/specific rules for the determination of the Reference Service Life (RSL).
This European Standard is intended to be used for cradle to gate or cradle to grave assessment, provided the intention is properly stated in the system boundary description.
