Wood-based panels - Determination of formaldehyde release - Part 2: Small-scale chamber method (ISO 12460-2:2024)

This document specifies a procedure for a chamber test with different options of chamber sizes to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature, relative humidity, loading and air exchange rate.
Results obtained from this small-scale chamber test method can be used for quality control (factory production control – ‘FPC’) based on correlation established by reference chamber test methods according to ISO, EN or ASTM standards. The establishment of a correlation is described in Annex D.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters o

Wood-based panels - Determination of characteristic 5-percentile values and characteristic mean values
EN 1058:2024

On the basis of test results from wood-based panel products for structural purposes, this document
specifies a method for the determination of:
— characteristic 5-percentile values of mechanical properties under the assumption of a log-normal
distribution of the test data according to EN 14358; and
— characteristic mean values (50-percentile values) of physical properties under the assumption of a
normal distribution of the test data according to EN 14358.
Test data can be determined from tests using the test methods outlined in the test standard EN 789 or
other relevant test standard, performance standard or product standard normatively referring to
EN 1058.
NOTE See e.g. EN 1195 and EN 12871.
The statistical evaluation follows the principles of EN 1990:20231, Annex D of EN 1995-1-1:20042 and of
EN 14358:2016.

Durability of wood and wood-based products - Test method against wood destroying basidiomycetes - Part 3: Assessment of durability of wood-based panels
EN 113-3:2023

This European Standard describes a method for assessing the resistance of wood-based panel products to attack by wood-destroying basidiomycete fungi growing in pure culture.
The method is applicable to uncoated, rigid wood-based panel products. It is applicable to the determination of the decay resistance of wood-based panel products:
— made from naturally durable materials;
— made from materials treated with preservatives prior to manufacture;
— treated with a preservative which is introduced during manufacture, for example as an additive to the adhesive;
— treated with preservative after manufacture.
NOTE 1 This method can be used in conjunction with an appropriate ageing procedure, for example EN 73 or EN 84.
NOTE 2 Wood-based panel products that have received a preservative treatment after manufacture can be susceptible to attack through the cut edges of the test specimens and the decay resistance indicated can be less than that of complete panels used in service.
Annex A (informative) contains a guidance on sampling.
Annex B (normative) contains some methods of sterilization.
Annex C (informative) contains information on the culture vessels.
Annex D (informative) contains an example of a test report.
Annex E (informative) contains information on the test fungi.
