ISO 22007-4:2017 specifies a method for the determination of the thermal diffusivity of a thin solid disc of plastics in the thickness direction by the laser flash method. This method is based upon the measurement of the temperature rise at the rear face of the thin-disc specimen produced by a short energy pulse on the front face.
The method can be used for homogeneous solid plastics as well as composites having an isotropic or orthotropic structure. In general, it covers materials having a thermal diffusivity, α, in the range 1 × 10−7 m2⋅s−1 ; < α ; < 1 × 10−4 m2⋅s−1. Measurements can be carried out in gaseous and vacuum environments over a temperature range from −100 °C to +400 °C.
NOTE For inhomogeneous specimens, the measured values can be specimen thickness dependent.

This document specifies the characteristics of wheels for all heavy rail track gauges.
This document applies to heavy rail vehicles and applies, in principle, to other vehicles such as urban rail vehicles. Five steel grades, ER6, ER7, ER8, ERS8 and ER9, are defined in this document.
NOTE 1 Steel grade ERS8 has been introduced in this document as an optimization of steel grades ER8 and ER9 due to contact fatigue (RCF), taking into account service feedback from Europe, for example, BS 5892-3 in force in the United Kingdom.
Some features are provided as a Category 1 or Category 2 function.
The requirements defined in this document apply to cylindrical bores. Most requirements also apply to wheels with tapered bores. Specific requirements for tapered bores (e.g. geometrical dimensions, etc.) are defined in the technical specification.
This document applies to monobloc wheels in vacuum degassed steel, forged and rolled, with surface treated rims, which have already been the subject of extensive commercial applications on a European network or have complied with a technical approval procedure according to EN 13979-1:2020 to validate their design.
Annex A describes the evaluation process for accepting new materials that are not included in this document.
This document defines the requirements to be met for wheels; the technical approval procedure is not part of the scope of this document.
NOTE 2 A "surface-treated rim" is achieved by heat treatment which aims to harden the rim and create compressive residual stress.

This document specifies the requirements for materials, design and installation of the insulation of refrigerated liquefied gas (RLG) storage tank systems.
RLG storage tank systems store liquefied gas with a low boiling point, i.e. below normal ambient temperature.
The concept of storing such products in liquid form and in non-pressurized tanks therefore depends on the combination of latent heat of vaporization and thermal insulation.
Consequently, thermal insulation for RLG storage tank systems is not an ancillary part of the containment system (as for most ambient atmospheric hydrocarbon tanks) but it is an essential component and the storage tank system cannot operate without a properly designed, installed and maintained insulation system.
The main functions of the insulation in RLG storage tank systems are:
- to maintain the boil off at or below the specified limits;
- to protect the outer tank components by maintaining them at or above their minimum design temperature;
- to prevent damage by frost heave of the foundation/soil beneath the tank base slab (in combination with the slab heating system for tanks resting at grade);
- to minimize condensation and icing on the outer surfaces of the tank.
A wide range of insulation materials is available. However, the material properties differ greatly amongst the various generically different materials and also within the same generic group of materials.
Therefore, within the scope of this document, only general guidance on selection of materials is given.
NOTE For general guidance on selection of materials, see Annex A.
This document deals with the design and manufacture of site built, vertical, cylindrical, flat-bottomed tank systems for the storage of refrigerated, liquefied gases with operating temperatures between 0 °C and -196 °C.

This document specifies design, type test methods, marking and instruction requirements for cylinder valves with integrated pressure regulators (VIPRs) intended to be fitted to gas cylinders, pressure drums or tubes or used as a main valve for cylinder bundles that convey compressed, liquefied or dissolved gases.

These are requirements for VIPRs that are in addition to those given in the relevant closure standard, e.g. in ISO 10297 for cylinder valves, in ISO 17871 for quick-release cylinder valves, in ISO 17879 for self-closing cylinder valves or in ISO 23826 for ball valves. For ISO 17871, these requirements are only applicable to quick-release cylinder valves types B, C, D and E.

NOTE 1   If the pressure regulating system of a VIPR is acting as the primary valve operating mechanism, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826. This also includes designs where closure of the primary valve operating mechanism of a VIPR is obtained by closing the seat of the pressure regulating system.

NOTE 2   If the primary valve operating mechanism of a VIPR is located at the low pressure side of the pressure regulating system, it is covered by the relevant closure standard, e.g. ISO 10297, ISO 17871, ISO 17879 and ISO 23826.

NOTE 3   The term “pressure receptacle” is used within this document to cover instances where no differentiation is necessary between gas cylinders, bundles of cylinders, pressure drums and tubes.

This document does not apply to VIPRs for

a)    medical applications (see ISO 10524‑3),

b)    liquefied petroleum gas (LPG), and

c)    cryogenic applications.

NOTE 4   Additional requirements for a VIPR with a residual pressure device (RPD) are specified in ISO 15996.

NOTE 5   Additional requirements for pressure relief valves can exist in international/regional regulations/ standards.
