This document specifies a method for the measurement of 14C activity concentration in all types of water samples by liquid scintillation counting either directly on the test sample or following a chemical separation.

The method is applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater.

The detection limit depends on the sample volume, the instrument used, the sample counting time, the background count rate, the detection efficiency and the chemical recovery. The method described in this document, using currently available liquid scintillation counters and suitable technical conditions has a detection limit as low as 1 Bq l−1, which is lower than the WHO criteria for safe consumption of drinking water (100 Bq·l-1). 14C activity concentrations can be measured up to 106 Bq l-1 without any sample dilution.

It is the user’s responsibility to ensure the validity of this test method for the water samples tested.

This document applies to all open-plan offices, in which the following activities are performed:

— Space type 1: when the activity isn’t known yet – vacant floor plate;

— Space type 2: activity mainly focusing on outside of the room communication (by telephone/audio/video);

— Space type 3: activity mainly based on collaboration between people at nearest workstation;

— Space type 4: activity based on a small amount of collaborative work;

— Space type 5: activity which may involve receiving the public;

— Space type 6: combining activities within the same space.

It is a guide to support technical dialogue and formal commitment between the various stakeholders involved in the planning, design, construction or layout of open-plan workspaces: end customers, project owners, prescribers, consultants, etc.

This part of ISO 13784 specifies a test method for evaluating the reaction-to-fire performance of thermal insulating sandwich panel building systems for large rooms and the resulting flame spread on or within the thermal insulating sandwich panel building construction when it is exposed to heat from a simulated internal fire with flames impinging directly on its internal corner. The test method is not intended for evaluating a product's fire resistance.

This part of ISO 13784 is applicable to both freestanding and self-supporting, and frame-supported, thermal insulating sandwich panel systems, but only to wall and ceiling or roof constructions.

This document provides performance and test requirements for determining the acceptability of neutron dosimetry systems to be used for the measurement of personal dose equivalent, Hp(10), for neutrons ranging in energy from thermal to 20 MeV 1). No distinction between the different techniques available in the market place is made in the description of the tests. Only generic distinctions, for instance, as disposable or reusable dosemeters, are considered.

This document gives information for extremity dosimetry in the Annex A, based on recommendations given by ICRU Report 66. This document addresses only neutron personal monitoring and not neutron criticality accident conditions.

No qualification or correction of the dosimetry system at a workplace is required if the dosimetry system fulfils the criteria of ISO 21909-1. However, methodologies described in this document can be used to improve the quality of individual monitoring in specific workplace fields for all dosimetry systems.

As specified in ISO 21909-1, the Individual Monitoring Service (IMS) shall specify clearly in its documentation the energy range (as described in ISO 21909-1) for which the dosemeter is qualified.

This document provides methodology and criteria to qualify the dosimetry system at workplaces where it is used. The criteria in this document apply to dosimetry systems which do not meet the criteria with regard to energy and direction dependent responses described in ISO 21909-1. That means that this document shall be systematically used to qualify at workplaces a dosimetry system that does not fulfil the criteria of ISO 21909-1 on the dependence of the response on neutron energy and direction of incidence.

The qualification of the dosimetry system at workplace aims to demonstrate that:

— either, the non-compliance of the dosimetry system to some of the requirements on the energy or direction dependent responses defined in ISO 21909-1 will not lead to significant discrepancies in the dose determination for a certain workplace field;

— or, that the correction factor or function used for this specific studied workplace enables the dosimetry system to accurately determine the conventional dose value with uncertainties similar to the ones given in ISO 21909-1.

Methodologies to characterize the workplace field are also described in the normative annex A, to help performing the qualification of the dosimetry system.

This document is directed at all stakeholders who are involved: IMSs, accreditation or regulatory bodies, and users of the particular dosimetry systems (the user is meant as the entity which assigns the dosimetry system to the radiation worker and records the assigned dose.)

The provider of the dosimetry system shall provide the type test results corresponding to ISO 21909-1. However, in the case when the dosimetry system to qualify will not comply with all the criteria of ISO 21909-1 dealing with the energy and angle dependence of the response, some tests of the ISO 21909-1 can be not performed. In that case, the requirements in accordance of the part 2 (see 6.3) shall be fulfilled instead.

This document only addresses neutron personal monitoring and not neutron criticality accident conditions.

This document gives requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes.

NOTE 1 All pressures are expressed in megapascals and in bar. 1 MPa = 10 bar.

Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see clause 8).

Type A (Rubber) hoses are intended for use at a minimum temperature of -20 °C and Type B (Thermoplastics) hoses are intended for use at a minimum temperature of -10 °C.

NOTE 2 Hoses for use at temperatures lower than those specified above can be supplied by agreement between the manufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at the specified temperature.

This document specifies a method for the determination of alkylmercury compounds in filtered water samples by gas chromatography-mass spectrometry after phenylation and solvent extraction.

This method is applicable to determination of individual methylmercury (MeHg) and ethylmercury (EtHg) compounds in surface water and waste water.

The method can be applied to samples containing 0,2 μg/l to 10 μg/l of each compound as mercury mass. Depending on the matrix, the method may also be applicable to higher concentrations after suitable dilution of the sample or reduction in sample size.

This document provides guidance on developing and using conceptual site models (CSMs) through the various phases of investigation, remediation (if required), and any subsequent construction or engineering works.

It describes what CSMs are, what they are used for and what their constituents are. It stresses the need for an iterative and dynamic approach to CSM development.

This document is intended to be used by all those involved in developing CSMs and by those who rely on using them such as regulators, landowners, developers, and the public (and other relevant parties). Ideally, this includes representatives from all phases of the investigative and remedial processes, for example, preliminary assessment, detailed investigation, baseline human health and environmental risk assessments, and feasibility study, and, any subsequent construction or engineering work.

NOTE 1 This document is applicable whenever the presence of "potentially harmful" or "hazardous" substances are present irrespective of whether they are naturally occurring or present due to human activity (i.e. are "contaminants").

NOTE 2 Although most of the principles described for developing CSMs in this document can apply to other domains, such as groundwater resources management, the present document is specifically written for the management of potentially contaminated sites or known contaminated sites.

This part of ISO 389 specifies the following data applicable to the calibration of bone vibrators for puretone

bone-conduction audiometry:

a) reference equivalent threshold vibratory force levels (RETVFL), corresponding to the threshold of

hearing of young otologically normal persons by bone-conduction audiometry;

b) essential characteristics of the bone vibrator and the method of coupling to the test subject, and to

the mechanical coupler;

c) essential characteristics of the masking noise and the baseline masking noise level applied to the

ear not under test.

Guidance on the practical application of this part of ISO 389 in the calibration of audiometers is

given in Annex B.

RETVFL is the vibratory force level transmitted to a mechanical coupler of specified characteristics by a

vibrator when applied to the mechanical coupler under stated conditions of test and when energized at the

voltage level corresponding to the normal threshold of hearing for location on the mastoid prominence.

NOTE 1 Values for the differences in reference equivalent threshold vibratory force levels between location on

the forehead and mastoid are included for information in Annex C.

NOTE 2 Recommended procedures for carrying out bone-conduction audiometry are specified in ISO 8253‑1.

This document specifies a method for the physical pre-treatment and conditioning of water samples and the determination of the activity concentration of various radionuclides emitting gamma rays with energies 40 keV < E < 2 MeV, by gamma-ray spectrometry according to the generic test method described in ISO 20042.

NOTE The determination of the activity concentration of radionuclides emitting gamma rays with energy below 40 keV and above 2 MeV is also possible within the scope of this document, provided both the calibration of the measuring system and the shielding are adapted to this purpose.

This document is only applicable to homogeneous samples. The lowest limit that can be measured as such, i.e. without dilution or concentration of the sample or anti Compton device is about 5.10-2 Bq/l for eg 137Cs. The upper limit of the activity corresponds to a dead time of 5%.

Depending on different factors, such as the energy of the gamma rays and the emission probability per nuclear disintegration, the size and geometry of the sample and the detector, the shielding, the counting time and other experimental parameters, the sample is concentrated by evaporation when activities below 5.10-2 Bq/l have to be measured. However, volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation.

When the dead time is higher than 5%, the sample is either diluted or an aliquot of the sample is taken or the source to detector distance is increased or a correction for pile-up effects is applied.

This document provides a selection of test methods and their associated principles for the measurement of the activity of 90Sr in equilibrium with 90Y, and 89Sr, pure beta-emitting radionuclides, in water samples. Different chemical separation methods are presented to produce strontium and yttrium sources, the activity of which are determined using a proportional counter (PC) or liquid scintillation counter (LSC).

The selection of a particular test method depends on the origin of the contamination, the characteristics of the water to be analyzed, the required accuracy of test results and the available resources of the laboratory.

These test methods are used for water monitoring following past or present, accidental or routine, liquid or gaseous discharges. It also covers the monitoring of contamination caused by global fallout.

When fallout occurs immediately following a nuclear accident, the contribution of 89Sr to the total amount of strontium activity is not negligible. This document provides test methods to determine the activity concentration of 90Sr in presence of 89Sr.
