This part of ISO 13164 gives general guidelines for sampling, packaging, and transporting of all kinds of

water samples, for the measurement of the activity concentration of radon-222.

The test methods fall into two categories:

a) direct measurement of the water sample without any transfer of phase (see ISO 13164-2);

b) indirect measurement involving the transfer of the radon-222 from the aqueous phase to another

phase (see ISO 13164-3).

The test methods can be applied either in the laboratory or on site.

The laboratory is responsible for ensuring the suitability of the test method for the water samples tested.

This part of ISO 13164 specifies a test method for the determination of radon-222 activity concentration

in a sample of water following the measurement of its short-lived decay products by direct gammaspectrometry

of the water sample (see Annex A).

The radon-222 activity concentrations, which can be measured by this test method utilizing currently

available gamma-ray instruments, range from a few becquerels per litre to several hundred thousand

becquerels per litre for a 1 l test sample.

This test method can be used successfully with drinking water samples. The laboratory is responsible

for ensuring the validity of this test method for water samples of untested matrices.

Annex B gives indication on the necessary counting conditions to meet the required sensitivity for

drinking water monitoring.

This part of ISO 13165 specifies the determination of radium-226 (226Ra) activity concentration in all

types of water by emanometry.

The method specified is suitable for the determination of the soluble, suspended, and total 226Ra activity

concentration in all types of water with soluble 226Ra activity concentrations greater than 0,02 Bq l−1.

In water containing high activity concentrations of 228Th, interference from 220Rn decay products can

lead to overestimation of measured levels (see Figure A.2).

This standard aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from releases of flammable gas, pressurised liquefied gas or flashing liquid fuels that may precede a fire. This standard may also be applicable to dust explosions. Gas explosions can give rise to pressure and drag forces. Damage to PFP materials in a gas explosion can be caused by the direct effects of pressure and drag loadings and by the deflection of the substrate supporting the PFP material. Other parts of this standard will deal with a range of common types of specimen that could be tested against the mechanical loads generated.

This document specifies the measurement of displacements across a line by means of inclinometers carried out for geotechnical monitoring. General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674-1.

This document also refers to deflectometers (see Annex B) to supplement inclinometers for the determination of horizontal displacements across horizontal measuring lines.

NOTE In general, there are two independent displacement components acting across measuring lines. Inclinometers allow the determination of the two components for vertical measuring lines. For horizontal lines, inclinometers are limited to the determination of the vertical component only.

If applied in conjunction with ISO 18674-2, this document allows the determination of displacements acting in any direction.

This document is applicable to:

— checking geotechnical designs in connection with the observational design procedure;

— monitoring of geotechnical structures prior to, during and after construction (e.g. natural slopes, slope cuts, embankments, excavation walls, foundations, dams, refuse dumps, tunnels);

— deriving geotechnical key parameters (e.g. from results of pile load tests or trial tunnelling);

— identification and monitoring of active shear planes in the ground.

NOTE This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of inclinometers as part of the geotechnical investigation and testing in accordance with References [1] and [2].

This document specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test procedures for Bicyclist Detection and Collision Mitigation Systems (BDCMS). It also defines the system test criteria necessary to verify that a given implementation meets the requirements of this document. Implementation choices are left to system designers, wherever possible.

BDCMS is fundamentally intended to provide emergency braking of equipped vehicles in order to mitigate collision severity between the subject vehicle and a bicyclist. BDCMS detect bicyclists forward of the subject vehicle, determine if the detected bicyclists are in a hazardous situation with respect to the subject vehicle, and initiate emergency braking if a hazardous situation exists and a collision is imminent. Systems that include other countermeasures such as evasive steering are outside the scope of this document.

The standard defines two types of BDCMS (based on operation in different ambient illuminance) and two classes of BDCMS (based on operation on different vehicle size classes). The standard does not apply to motorcycles. The operational design domain is public roads. BDCMS is not intended for off-road use.

Table 1 — Types and Classes of BDCMS

Responsibility for the safe operation of the vehicle remains with the driver.

Licensable motor vehicles intended for use on public roads, i.e. motorcycles, cars, light trucks, buses, motor coaches, and other heavy vehicles as hazards are outside the scope of this document and are covered under ISO 22839, Intelligent transportation systems — Forward vehicle collision mitigation systems — Operation, performance, and verification requirements.

Pedestrians are outside the scope of this document and are covered under ISO 19237, Intelligent transportation systems — Pedestrian detection and collision mitigation systems (PDCMS) — Performance requirements and test procedures.

1.1 This part of ISO 15202 specifies a number of suitable methods for preparing test solutions from samples of airborne particulate matter collected using the method specified in ISO 15202-1, for subsequent determination of metals and metalloids by ICP-AES using the method specified in ISO 15202-3. It contains information about the applicability of the methods with respect to the measurement of metals and metalloids for which limit values have been set. The methods can also be used in the measurement of some metals and metalloids for which limit values have not been set but no information about its applicability is provided in this case.

NOTE The sample preparation methods described in this part of ISO 15202 are generally suitable for use with analytical techniques other than ICP-AES, e.g. atomic absorption spectrometry (AAS) by ISO 8518[5] and ISO 11174[10] and inductively coupled plasma mass spectrometry (ICP-MS) by ISO 30011[11].

1.2 The method specified in Annex B is applicable when making measurements for comparison with limit values for soluble metal or metalloid compounds.

1.3 One or more of the sample dissolution methods specified in Annexes C through H are applicable when making measurements for comparison with limit values for total metals and metalloids and their compounds. Information on the applicability of individual methods is given in the scope of the annex in which the method is specified.

1.4 The following is a non-exclusive list of metals and metalloids for which limit values have been set (see References [14] and [15]) and for which one or more of the sample dissolution methods specified in this part of ISO 15202 are applicable. However, there is no information available on the effectiveness of any of the specified sample dissolution methods for those elements in italics.

ISO 15202 is not applicable to the determination of elemental mercury or arsenic trioxide, since mercury vapour and arsenic trioxide vapour are not collected using the sampling method specified in ISO 15202-1.
