This European Standard provides the methodology for measuring and characterizing the dustiness of a bulk material that contains or releases nano-objects or submicrometer particles. In addition, it specifies the environmental conditions, the sample handling procedure and the method of calculating and presenting the results. Guidance is given on the choice of method to be used.

The methodology described in this European Standard enables

a) the quantification of dustiness in terms of health-related index mass fractions,

b) the quantification of dustiness in terms of an index number and an emission rate, and

c) the characterization of the aerosol from its particle size distribution and the morphology and chemical composition of its particles.

NOTE 1 Currently, no number-based classification scheme in terms of particle number has been established for particle dustiness release. Eventually, when a large enough number of measurement data has been obtained, the intention is to revise this European Standard and to introduce a number-based classification scheme.

This European Standard is applicable to all bulk materials, including powders, granules or pellets, containing or releasing nano-objects or submicrometer particles.

NOTE 2 The vortex shaker method specified in part 5 of this European Standard has not yet been evaluated for pellets and granules.

NOTE 3 The rotating drum and continuous drop methods have not yet been evaluated for nanofibres and nanoplates.

This European Standard does not provide methods for assessing the release of particles during handling or mechanical reduction of machining (e.g. crushing, cutting, sanding, sawing) of solid nanomaterials (e.g. nanocomposites).

This European Standard provides the methodology for measuring the dustiness of bulk materials that contain or release nano-objects or submicrometer particles, under standard and reproducible conditions and specifies for that purpose the rotating drum method.

In addition, this European Standard specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data.

The methodology described in this European Standard enables

a) the measurement of the respirable, thoracic and inhalable dustiness mass fractions,

b) the measurement of the number-based dustiness index of respirable particles in the size range from about 10 nm to 1 000 nm,

c) the measurement of the number-based emission rate of respirable particles in the size range from about 10 nm to 1 000 nm,

This European Standard provides the methodology for measuring and characterizing the dustiness of bulk materials that contain or release nano-objects or submicrometer particles, under standard and reproducible conditions and specifies for that purpose the vortex shaker method.

In addition, this European Standard specifies the selection of instruments and devices and the procedures for calculating and presenting the results. It also gives guidelines on the evaluation and reporting of the data.

The methodology described in this European Standard enables

a) the measurement of the respirable dustiness mass fraction,

b) the determination of the mass-based dustiness index of respirable particles in the size range from about 10 nm to 1 000 nm;

c) the determination of the number-based dustiness index of respirable particles in the size range from about 10 nm to 1 000 nm;

d) the determination of the number-based emission rate of respirable particles in the size range from about 10 nm to 1 000 nm;

e) the determination of the number size distribution of the released respirable aerosol in the size range from about 10 nm to 10 μm;

f) the collection of released airborne particles in the respirable fraction for subsequent observations and analysis by electron microscopy.

This European Standard is applicable to the testing of a wide range of bulk materials including nanomaterials in powder form.

NOTE 1 With slightly different configurations of the method specified in this European Standard, dustiness of a series of carbon nanotubes has been investigated ([5] to 10]). On the basis of this published work, it can be assumed that the vortex shaker method is also applicable to nanofibres and nanoplates.

This European Standard is not applicable to millimetre-sized granules or pellets containing nano-objects in either unbound, bound uncoated and coated forms.

NOTE 2 This comes from the configuration of the vortex shaker apparatus and the small test sample required. Eventually, if future work provides accurate and repeatable data demonstrating that this is possible, the intention is to revise the European Standard and to introduce this application.

NOTE 3 As observed in the pre-normative research Project [4], the vortex shaker method specified in this European Standard provides a more energetic aerosolization than the rotating drum, the continuous drop and the small rotating drum specified in prEN 17199-2:2017 [1], prEN 17199-3:2017 [2] and prEN 17199-4:2017 [3], respectively. It can better simulate high energy dust dispersion operations or processes where vibration is applied or even describe a worst case scenario in a workplace, including the (non-recommended) practice of cleaning contaminated worker coveralls and dry work surfaces with compressed air.

NOTE 4 Currently no classification scheme in terms of dustiness indices or emission rates has been established according to te vortex shaker method. Eventually, when a large number of measurement data has been obtained, the intention is to revise the European Standard and to introduce such a classification scheme, if applicable.

This part of ISO 20088 describes a method for determining the resistance of a Cryogenic Spill Protection (CSP) systems to a cryogenic jet as a result of a pressurised release which does not result in immersion conditions. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.

A cryogenic jet may be formed upon release from process equipment operating at pressure (e.g., some liquefaction processes utilise 40 - 60 bar operating pressure). Due to high pressure discharge, the cryogenic spillage protection may be compromised by the large momentum combined with extreme cryogenic temperature.

Although the test uses liquid nitrogen (LIN) as the cryogenic liquid, the test described in this standard is representative of a release of LNG, through a 20mm orifice or less, at a release pressure of 6 barg or less, based upon simulated parameters 1 m from the release point. Confidence in this test being representative is based upon a comparison of the expected dynamic pressure of the simulated release in comparison with dynamic pressure from releases in accordance with this part of the ISO 20088 standard.

It should be recognised that it is not practical in this test to cover the whole range of cryogenic process conditions found in real plant conditions; in particular the test does not cover high pressure cryogenic jet releases that may be found in refrigeration circuits and in LNG streams immediately post-liquefaction.

LIN is used as the cryogenic medium due to the ability to handle the material at the pressures described in this part of the standard safely. The test condition is run at 8 barg pressure.

Part 1 of the standard covers cryogenic release scenarios which may lead to immersion conditions for steel work protected by cryogenic spill protection as a result of a jet release or low pressure release of LNG or LIN. Part 2 of the standard covers vapour phase exposure conditions as a result of a jet release or low pressure release of LNG or LIN.

This Technical Specification provides guidance for a probabilistic approach for fire safety engineering. Guidance is given for the use of fire safety engineering methods to evaluate compliance with an absolute criterion. This guidance can also be used in combination with INSTA/TS 950 in order to evaluate compliance with a comparative criterion. Performance criteria (acceptance criteria), relevant fire safety engineering methods and input data (reliability data and fire statistics) are within the scope of this report.

This document is intended to be used as a reference for building authorities and for use in verifying compliance with regulations by fire safety designers, local authorities and others in the building industry.

The information given within this Technical Specification should not be seen as requirements, but guidance on verifying compliance with functional requirements in a performance-based regime – e.g. performance criteria on property loss do not apply in regions or nations where only life safety is governed by the authority having jurisdiction. In these cases, a voluntary performance criteria for property safety must be set in in a process involving the relevant stakeholders.

NOTE Limitations regarding the use of this specification may be set in the National Annex.

The user of this Technical Specification must verify that applied models are valid for the relevant design situation and that national requirements are met.

This Technical Report provides guidance for when and how to conduct review and control within the field of performance based fire safety design as a part of the overall building process.

The aim of the process that has been developed is to facilitate verification of building solutions including innovative and sustainable solutions and to harmonize the process for control within the field of fire safety engineering in the Nordic countries.

The focus for the process is on a general level for review and control, independent of national legal matters in the Nordic countries, with a primary focus on technical issues within fire safety engineering. But the process will also, to some extent, give guidance on how the fire safety design process, including engineering approaches, can be a normal part of the overall control and review of the building process and define eligibility criteria for those doing the control.

This specification includes:

when to perform controls within the building process and within the specific fire safety design process;

how to perform the controls;

why the controls should be performed and their purpose.

This specification is intended to be used as a reference document for building authorities and for use in connection with regulations by consultants, local authorities and stakeholders in the building industry.

NOTE Limitations regarding the use of this specification may be set in the National Annex.

The user of this specification must verify that the described processes are valid to the relevant design situation and that national requirements are met. It does not detail all the engineering knowledge required for the building fire safety design.

This international standard describes methods to determine the activity in becquerel (Bq) of gamma-emitting radionuclides by gamma spectrometry in solid, liquid or gaseous test samples after proper preparation in a testing laboratory. Applications include:

— routine surveillance of radioactivity released from nuclear installations or from sites discharging enhanced levels of naturally occurring radioactive materials;

— contributing to determining the evolution of radioactivity in the environment;

— investigating accident and incident situations, in order to plan remedial actions and monitor their effectiveness;

— assessing potentially contaminated waste materials from decommissioning legacy nuclear sites;

— surveillance of radioactive contamination in media such as soils, foodstuffs, potable water, groundwaters, seawater or sewage sludge;

— measurements for estimating the intake (inhalation, ingestion or injection) of activity of gamma-emitting radionuclides in the body.

It is assumed that the user of this standard has been given information on the composition of the test sample (or the site). In some cases, the radionuclides for analysis may also have been specified if characteristic limits are required. It is also assumed that the test sample has been homogenised and is representative of the material under test.

General guidance is included for preparing the samples for measurement. However, some types of sample are to be prepared following the requirements of specific standards referred to in this document. The generic recommendations can also be useful for the measurement of gamma emitters in situ.

This standard includes generic advice on equipment selection (a list of factors to be considered) (more detailed information is included in Annex A), detectors (more detailed information is included in Annex D), and commissioning of instrumentation and method validation. The informative Annex F summarises the influence of different measurement parameters on results for a typical gamma spectrometry system. Quality control and routine maintenance are also covered, but electrical testing of the detector and pulse processing electronics is excluded. It is assumed that any data collection and analysis software used has been written and tested in accordance with relevant software standards such as ISO/IEC 12207.

Calibration using reference materials and/or numerical methods is covered, including verification of the results. It also covers the procedure to estimate the activity content of the sample (Bq) from the spectrum. The procedure for the measurement of gamma emitting radionuclides in situ is covered in ISO 18589-7 and is outside the scope of this document.

The standard covers, but is not restricted to, gamma emitters which emit photons in the energy range of 5 keV to 3000 keV. However, the most measurements fall into the range 40 keV to 2 000 keV. The activity (Bq) ranges from the low levels (sub-Bq) found in environmental samples to activities found in accident conditions and high level radioactive wastes.
