ISO/IEC GUIDE 98-3:2008 Uncertainty of measurement — Part 3: Guide to the expression of uncertainty in measurement (GUM:1995)

1.1 This Guide establishes general rules for evaluating and expressing uncertainty in measurement that can be followed at various levels of accuracy and in many fields — from the shop floor to fundamental research. Therefore, the principles of this Guide are intended to be applicable to a broad spectrum of measurements, including those required for:
- maintaining quality control and quality assurance in production;
- complying with and enforcing laws and regulations;
- conducting basic research, and applied research and development, in science and engineering;
- calibrating standards and instruments and performing tests throughout a national measurement system in order to achieve traceability to national standards;
- developing, maintaining, and comparing international and national physical reference standards, including reference materials.
1.2 This Guide is primarily concerned with the expression of uncertainty in the measurement of a well-defined physical quantity — the measurand — that can be characterized by an essentially unique value. If the phenomenon of interest can be represented only as a distribution of values or is dependent on one or more parameters, such as time, then the measurands required for its description are the set of quantities describing that distribution or that dependence.
1.3 This Guide is also applicable to evaluating and expressing the uncertainty associated with the conceptual design and theoretical analysis of experiments, methods of measurement, and complex components and systems. Because a measurement result and its uncertainty may be conceptual and based entirely on hypothetical data, the term “result of a measurement” as used in this Guide should be interpreted in this broader context.
1.4 This Guide provides general rules for evaluating and expressing uncertainty in measurement rather than detailed, technology-specific instructions. Further, it does not discuss how the uncertainty of a particular measurement result, once evaluated, may be used for different purposes, for example, to draw conclusions about the compatibility of that result with other similar results, to establish tolerance limits in a manufacturing process, or to decide if a certain course of action may be safely undertaken. It may therefore be necessary to develop particular standards based on this Guide that deal with the problems peculiar to specific fields of measurement or with the various uses of quantitative expressions of uncertainty.* These standards may be simplified versions of this Guide but should include the detail that is appropriate to the level of accuracy and complexity of the measurements and uses addressed.

EN 13164:2008 Thermal insulation products for buildings - Factory made products of extruded polystyrene foam (XPS) - Specification

This European Standard specifies the requirements for factory made products of extruded polystyrene foam,
with or without facings or coatings, which are used for thermal insulation of buildings. The products are
manufactured in the form of boards, which are also available with special edge and surface treatment
(tongue and grooves, shiplap, etc.).
This European Standard specifies product characteristics and includes procedures for testing, evaluation of
conformity, marking and labelling.
Products covered by this European Standard are also used in prefabricated thermal insulating systems and
composite panels; the performance of systems incorporating these products is not covered. This European
Standard also covers multilayered insulation boards.
This European Standard does not specify the required level of a given property to be achieved by a product to
demonstrate fitness for purpose in a particular application. The levels required for a given application are to be
found in regulations or non-conflicting standards.
Products with a declared thermal resistance lower than 0,25 m2⋅K/W or a declared thermal conductivity
greater than 0,060 W/(m⋅K) at 10 °C are not covered by this European Standard.
This European Standard does not cover in situ insulation products and products intended to be used for the
insulation of building equipment and industrial installations or products intended for acoustic insulation.
