This European Standard gives the definition, classification and symbols for wood fibreboards.

This standard applies to the measurement of fugitive emissions of volatile organic compounds (VOCs) from process equipment. The leak sources include, but are not limited to, valves, flanges and other connections, pressure relief devices, process drains, open-ended valves, pump and compressor seal systems, agitator seals, and access door seals. It does not apply to instrument tubing connections.
This standard applies to all products of which at least 20 % wt has a vapour pressure higher than 0,3 kPa at 20 °C. For the petroleum industry, this includes all light products and excludes kerosene and all heavier products.
The standard is based on the measurement of the gas concentration at the interface of a leak. This concentration is measured with a portable instrument. It is converted to a mass emission rate by use of a set of correlations. The scope of this standard includes the complete data processing, from the initial concentration measurement up to the generation of an emission report over a reporting period (which is generally one year) ).
This standard does not prescribe the number of potential emission points that should be screened each year nor the frequency at which these points should be screened. This sampling strategy shall indeed take into account the plant characteristics and the required level of control over fugitive emissions.
Optical methods are currently under development to ease the detection of leaks in plants and use of this standard in conjunction with these methods might be possible. In any case, measurements have to be performed according to the requirements of this standard. To enable direct quantification of total fugitive emissions based only on these methods, a subsequent revision of this standard will be needed.

This standard specifies a Reverse Dispersion Modelling method to qualify the fugitive emission rates of diffuse fine and coarse dust sources of industrial plants or areas. The application needs calculations using a dispersion model, and the definition of a sampling experimental set-up taking into account field data such as number, height and width of diffuse dust sources, sampling distances, and meteorological information.
The RDM method does not allow quantification in absolute figures of the dust emission rates because of an undetermined accuracy depending on various site conditions, but it is a tool which enables each industrial plant to identify its dust sources that emit the most, and then to implement actions reducing their importance by self-control and related improvement process as part of environmental management.
In this framework, the RDM method should not be used to control or verify any compliance with air quality threshold global values which might be contained in an operating permit, or to carry out comparison between different plants belonging to the same industrial sector.

This International Standard specifies a method for determining the compressive properties of plastics under defined
conditions. A standard test specimen is defined but its length may be adjusted to prevent buckling under load from
affecting the results. A range of test speeds is included.
The method is used to investigate the compressive behaviour of the test specimens and for determining the
compressive strength, compressive modulus and other aspects of the compressive stress/strain relationship under
the conditions defined.
The method applies to the following range of materials:
 rigid and semi-rigid [1] thermoplastic moulding and extrusion materials, including compounds filled and
reinforced by e.g. short fibres, small rods, plates or granules in addition to unfilled types; rigid and semi-rigid
thermoplastic sheet;
 rigid and semi-rigid thermoset moulding materials, including filled and reinforced compounds; rigid and semirigid
thermoset sheet;
 thermotropic liquid-crystal polymers.
In agreement with ISO 10350-1 and ISO 10350-2, this International Standard applies to fibre-reinforced
compounds with fibre lengths u 7,5 mm prior to processing.
The method is not normally suitable for use with materials reinforced by textile fibres (see references [2] and [5]),
fibre-reinforced plastic composites and laminates (see [5]), rigid cellular materials (see [3]) or sandwich structures
containing cellular material or rubber (see [4]).
The method is performed using specimens which may be moulded to the chosen dimensions, machined from the
central portion of a standard multipurpose test specimen (see ISO 3167) or machined from finished or semifinished
products such as mouldings or extruded or cast sheet.
The method specifies preferred dimensions for the test specimen. Tests which are carried out on specimens of
different dimensions, or on specimens which are prepared under different conditions, may produce results which
are not comparable. Other factors, such as the test speed and the conditioning of the specimens, can also
influence the results. Consequently, when comparable data are required, these factors must be carefully controlled
and recorded.

When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, for machines that have been designed and built according to the provisions of this type C standard.

This method of EN 1366 specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction system is only intended to function up to flashover (typically 600 °C). The smoke extraction duct is part of the smoke extraction system which also includes smoke control dampers and smoke extract fans.
This test method of part 9 is applicable only to smoke extraction ducts that do not pass through into other fire compartments. It represents fire exposure of a developing fire (pre-flashover).
For smoke extraction ducts that pass through into other compartments, the method of test described in EN 1366-8 should be used.
This test has been designed to cover horizontal smoke extraction ducts intended for single compartment applications only.
This method of test is only suitable for ducts constructed from non-combustible materials (euro class A1).
It is applicable only to four sided ducts and two and three sided ducts are not covered.
The method described in this test is complex and requires sophisticated instrumentation. It is not recommended therefore to try to test multiple assemblies in this test.
