Sensory analysis — Methodology — General guidance for measuring odour, flavour and taste detection thresholds by a three-alternative forced-choice (3-AFC) procedure

Analyse sensorielle — Méthodologie — Recommandations générales pour le mesurage des seuils de détection d'odeur, de flaveur et de goût par une technique à choix forcé de 1 parmi 3 (3-AFC)

ISO 13301:2018 gives guidelines for

-      obtaining data on the detection of stimuli that evoke responses to odour, flavour and taste by a 3-AFC (three-alternative forced-choice) procedure, and

-      the processing of the data to estimate the value of a threshold and its error bounds, and other statistics related to the detection of the stimulus.

Typically, the procedures will be used in one of the following two modes:

-      investigation of the sensitivity of assessors to specific stimuli;

-      investigation of the ability of a chemical substance to stimulate the chemoreceptive senses.

(Although experiments can encompass both modes.)

Examples of the first mode include studies of the differences among individuals or specified populations of individuals in sensitivities and of the effects of age, gender, physiological condition, disease, administration of drugs and ambient conditions on sensitivity. Examples of the latter mode include

-      studies in flavour chemistry and the impact of specified chemicals on the flavour of foods,

-      classification of chemicals for their impact on humans, if present in the environment,

-      studies on the relationship of molecular structure to capacity of a chemical to act as a stimulant,

-      quality assurance of gaseous effluents and of water, foods and beverages, and

-      studies in the mechanism of olfaction.

In both modes, the way in which probability of a correct response changes with intensity of stimulus, i.e. the slope of the dose/response curve, could be an important aspect of the study as well as the threshold value, and the data processing procedures described here provide this information.

The focus of ISO 13301:2018 is on data requirements and on computational procedures. Regarding the validity of the data, the text is restricted to general rules and precautions. It does not differentiate between detection and difference thresholds; fundamentally, the procedures measure a difference threshold because a test sample is compared with a reference sample. Typically, the reference sample is not intended to contain the stimulus under investigation, but the guidelines do not exclude experimental design in which the reference could contain the stimulus, or it might not be known if the reference contains the stimulus. The guidelines do not measure a recognition threshold as defined in ISO 5492. They do not address the standardization of methods of determining air quality as discussed in EN 13725.


Document management applications — Archiving of electronic data — Computer output microform (COM)/Computer output laser disc (COLD)

Applications de gestion de documents — Archivage de données électroniques — Microforme de sortie d'ordinateur (COM)/Disque laser de sortie d'ordinateur (COLD)

ISO 11506:2017 specifies techniques for archiving electronic data to ensure their long-term integrity, accessibility, usability, readability and reliability, in order to protect the evidential value of the data.

In ISO 11506:2017, long term is considered to be a period of time lasting more than a century (see ISO 18911).

Black-and-white microforms processed with liquid chemicals are used in ISO 11506:2017 because the result is always an irreversible record and because of the proven quality of microforms as a long-term preservation media.

ISO 11506:2017 also specifies procedures for the parallel recording, by a single production unit, of COM and COLD output from the same data.

It applies to many different types of electronic data, such as text and two-dimensional graphic data which can be represented as a black-and-white image.

It is not applicable to the following:

-      animated images or sounds;

-      three-dimensional images;

-      images in shades of grey or in colour;

-      X-ray images.

Neither is ISO 11506:2017 applicable to microforms created from dry thermal processes, since they offer insufficient guarantees in terms of irreversibility and longevity.

Information technology — Relayed Multicast Control Protocol (RMCP) — Framework — Part 1:

Technologies de l'information — Protocole de multidiffusion relayé (RMCP) — Cadre général — Partie 1:

Relayed multicast protocol (RMCP) is a protocol which is used to realize a relayed multicast data transport scheme. Different from the conventional IP multicast, RMCP can configure a relayed multicast path that multicast traffic flows by using intermediate end-hosts. RMCP can be applied to the current unicast based IP network where IP multicast is not fully deployed.

ISO/IEC 16512-1:2016 addresses the basic concepts needed to specify RMCP for relayed multicast. It defines the related terminology and proposes a framework for the future development of subsequent protocols. The framework covers network topology including network entities and the relationship among them, service scenarios, basic operations, and message format.

RMCP-2 defines relayed multicast data transport capabilities over IP‑based networks for simplex group applications.

This Recommendation | International Standard specifies the following:

a)    descriptions of the entities, control and data delivery models of RMCP-2;

b)    description of the functions and procedures of multicast agents (MAs) to construct a one-to-many relayed data path and to relay data for simplex communication;

Earth-moving machinery — Laboratory evaluation of operator seat vibration

Engins de terrassement — Évaluation en laboratoire des vibrations transmises à l'opérateur par le siège

1.1  This document specifies, in accordance with ISO 10326‑1:2016, a laboratory method for measuring and evaluating the effectiveness of the seat suspension in reducing the vertical whole-body vibration transmitted to the operator of earth-moving machines at frequencies between 1 Hz and 20 Hz. It also specifies acceptance criteria for application to seats on different machines.

1.2  This document is applicable to operator seats used on earth-moving machines as defined in ISO 6165.

1.3  This document defines the input spectral classes required for the following earth-moving machines. Each class defines a group of machines having similar vibration characteristics:

—     rigid-frame dumpers >4 500 kg operating mass;

—     articulated-frame dumpers;

—     scrapers without axle or frame suspension[1];

—     wheeled loaders >4 500 kg operating mass;

—     graders;

—     wheeled dozers;

—     soil compactors;

—     backhoe loaders;

—     crawler dumpers;

—     crawler loaders;

—     crawler-dozers ≤50 000 kg operating mass[2];

—     compact dumpers ≤4 500 kg operating mass;

—     wheeled compact loaders ≤4 500 kg operating mass;

—     skid-steer loaders, wheeled ≤4 500 kg and tracked ≤6 000 kg operating mass.

1.4  The following machines impart sufficiently low vertical vibration inputs at frequencies between 1 Hz and 20 Hz to the seat during operation that these seats do not require suspension for the attenuation of transmitted vibration:

—     excavators, including walking excavators and cable excavators[3];

—     trenchers;

—     landfill compactors;

—     non-vibratory rollers, except soil compactors;

—     vibratory rollers, except soil compactors;

—     pipelayers;

—     horizontal directional drills (HDD).

1.5  The tests and criteria defined in this document are intended for operator seats used in earth-moving machines of conventional design.

NOTE    Other tests can be appropriate for machines with design features that result in significantly different vibration characteristics.

1.6  Vibration which reaches the operator other than through the seat, for example that sensed by the operator's feet on the platform or control pedals or by the operator´s hands on the steering-wheel, is not covered.

[1]     For scrapers with suspension, either a seat with no suspension can be used, or one having a suspension with high damping.

[2]     For crawler dozers greater than 50 000 kg, the seat performance requirements are suitably provided by a cushion type seat.

[3]     For excavators, the predominant vibration is generally in the fore and aft (X) axis.


Liquid petroleum products — Determination of hydrocarbon types and oxygenates in automotive-motor gasoline and in ethanol (E85) automotive fuel — Multidimensional gas chromatography method

Produits pétroliers liquides — Détermination des groupes d'hydrocarbures et des composés oxygénés de l'essence pour moteurs automobiles et du carburant pour automobiles éthanol (E85) — Méthode par chromatographie multidimensionelle en phase gazeuse

ISO 22854:2016 specifies the gas chromatographic (GC) method for the determination of saturated, olefinic and aromatic hydrocarbons in automotive motor gasoline and ethanol (E85) automotive fuel. Additionally, the benzene content, oxygenate compounds and the total oxygen content can be determined.

NOTE 1       For the purposes of this document, the terms % (m/m) and % (V/V) are used to represent respectively the mass fraction, µ, and the volume fraction, φ.

ISO 22854:2016 defines two procedures, A and B.

Procedure A is applicable to automotive motor gasoline with total aromatics of up to 50 % (V/V); total olefins from about 1,5 % (V/V) up to 30 % (V/V); oxygenates from 0,8 % (V/V) up to 15 % (V/V); total oxygen from about 1,5 % (m/m) to about 3,7 % (m/m); and benzene of up to 2 % (V/V). The system can be used for ethers with 5 or more C atoms up to 22 % (V/V) but the precision has not been established up to this level.

Although this test method can be used to determine higher-olefin contents of up to 50 % (V/V), the precision for olefins was tested only in the range from about 1,5 % (V/V) to about 30 % (V/V).

Although specifically developed for the analysis of automotive motor gasoline that contains oxygenates, this test method can also be applied to other hydrocarbon streams having similar boiling ranges, such as naphthas and reformates.

NOTE 2       For Procedure A, precision data have been established for the oxygenate compounds in automotive motor gasoline samples containing ethyl-tert-butyl ether (ETBE), methyl-tert-butyl ether (MTBE), tert-amyl-methyl ether (TAME), iso-propanol, iso-butanol, tert-butanol, methanol and ethanol. The derived precision data for methanol do not comply with the precision calculation as presented in this International Standard. Applicability of this International Standard has also been verified for the determination of n-propanol, acetone, and di-isopropyl ether (DIPE). However, no precision data have been determined for these compounds.

Procedure B describes the procedure for the analysis of oxygenated groups (ethanol, methanol, ethers, C3 ? C5 alcohols) in ethanol (E85) automotive fuel containing ethanol between 50 % (V/V) and 85 % (V/V). The gasoline is diluted with an oxygenate-free component to lower the ethanol content to a value below 20 % (V/V) before the analysis by GC. If the ethanol content is unknown, it is advisable to use a dilution of 4:1 when analysing the sample.

The sample can be fully analysed including hydrocarbons. Precision data for the diluted sample are only available for the oxygenated groups.

NOTE 3       For Procedure B, the precision can be used for an ethanol fraction from about 50 % (V/V) up to 85 % (V/V). For the ether fraction, the precision as specified in Table 6 can be used for samples containing at least 11 % (V/V) of ethers. For the higher alcohol fraction, too few data were obtained to derive a full precision statement and the data presented in Table 6 are therefore only indicative.

NOTE 4       While developing this test method, the final boiling point was limited to 215 °C.

NOTE 5       An overlap between C9 and C10 aromatics can occur. However, the total is accurate. Isopropyl benzene is resolved from the C8 aromatics and is included with the other C9 aromatics.
