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 part of ISO 13165 specifies the determination of radium-226 (226Ra) activity concentration in all types of water by coprecipitation followed by gamma-spectrometry (see ISO 18589‑3).

The method described is suitable for determination of soluble 226Ra activity concentrations greater than 0,02 Bq l−1 using a sample volume of 1 l to 100 l of any water type.

For water samples smaller than a volume of 1 l, direct gamma-spectrometry can be performed following ISO 10703 with a higher detection limit.

NOTE This test method also allows other isotopes of radium, 223Ra, 224Ra, and 228Ra, to be determined.

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 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.

This part of ISO 5667 sets out the general principles for, and provides guidance on, the design of sampling programmes and sampling techniques for all aspects of sampling of water (including waste waters, sludges, effluents, suspended solids and sediments).

It does not include detailed instructions for specific sampling situations, which are covered in the various other parts of ISO 5667 and in ISO 19458.

This document specifies a reference threshold of hearing for the calibration of audiometric equipment used under the following conditions.

a) The sound field in the absence of the listener consists of either a free progressive plane wave (free field) or a diffuse sound field, as specified in ISO 8253-2. In the case of a free field, the source of sound is directly in front of the listener (frontal incidence).

b) The sound signals are pure (sinusoidal) tones in the case of free field conditions and one third octave bands of (white or pink) noise in the case of diffuse field conditions.

c) The sound pressure level is measured in the absence of the listener at the position where the centre of the listener’s head would be.

d) Listening is binaural.

NOTE 1 Correction values for the threshold of hearing under free-field listening conditions and selected angles of sound incidence (45° and 90°) deviating from frontal incidence are given in ISO 8253-2 for information.

NOTE 2 Other conditions are given in Reference [1].

The data are given in numerical form for the preferred frequencies in the one-third-octave series from 20 Hz to 16 000 Hz inclusive in accordance with ISO 266 and, in addition, for some intermediate audiometric frequencies up to 18 000 Hz.

The threshold data differ from the audiometric zero specified in ISO 389-1, ISO 389-2, ISO 389-5 and ISO 389-8, since the latter refer to monaural listening through earphones with sound pressure levels referred to specified couplers and ear simulators. Direct comparison between the data in the parts of ISO 389 mentioned above and in this document is therefore not appropriate.
