Radiological protection - Characteristics of reference pulsed radiation - Part 1: Photon radiation (ISO/DIS 18090-1:2025)

ISO/TS 18090-1:2015 is directly applicable to pulsed X-radiation with pulse duration of 0,1 ms up to 10 s. This covers the whole range used in medical diagnostics at the time of publication. Some specifications may also be applicable for much shorter pulses; one example is the air kerma of one pulse. Such a pulse may be produced, e.g. by X-ray flash units or high-intensity femtosecond-lasers. Other specifications are not applicable for much shorter pulses; one example is the time-dependent behaviour of the air kerma rate. This may not be measurable for technical reasons as no suitable instrument is available, e.g. for pulses produced by a femtosecond-laser. ISO/TS 18090-1:2015 specifies the characteristics of reference pulsed radiation for calibrating and testing radiation protection dosemeters and dose rate meters with respect to their response to pulsed radiation. The radiation characteristics includes the following: a) time-dependent behaviour of the air kerma rate of the pulse; b) time-dependent behaviour of the X-ray tube high voltage during the pulse; c) uniformity of the air kerma rate within a cross-sectional area of the radiation beam; d) air kerma of one radiation pulse; e) air kerma rate of the radiation pulse; f) repetition frequency. ISO/TS 18090-1:2015 does not define new radiation qualities. Instead, it uses those radiation qualities specified in existing ISO and IEC standards. This part of ISO/TS 18090 gives the link between the parameters for pulsed radiation and the parameters for continuous radiation specifying the radiation qualities. It does not specify specific values or series of values for the pulsed radiation field but specifies only those limits for the relevant pulsed radiation parameters that are required for calibrating dosemeters and dose rate meters and for determining their response depending on the said parameters. The pulse parameters with respect to the phantom-related quantities were determined using conversion coefficients according to ISO 4037 (all parts). This is possible as the radiation qualities specified in existing ISO and IEC standards are used. A given reference pulsed X-ray facility is characterized by the parameter ranges over which the full specifications and requirements according to this part of ISO/TS 18090 are met. Therefore, not all reference pulsed X-ray facilities can produce pulses covering the same parameter ranges.

Railway applications - Braking - Brake performance

This document defines a harmonized way to assess the braking performance by test of locomotives, passenger coaches, freight wagons, railbound construction and maintenance machines, and self-propelled passenger trains (multiple units) including high speed trains. The document sets out the standardized method for undertaking brake performance tests and the correction factors to be applied to the data obtained for all types of rolling stock. This document also defines the methods to assess the brake performance in terms of stopping distance, and from this the process to determine vehicle(s) deceleration and braked weight. It then deals with conversion of the braked weight to the braked weight percentage of a vehicle or train for operating purposes. It also sets out additional factors when determining the braked weight percentage of a train calculated from specified braked weight, depending on the formation of the train. In Annex D there is a method for determining brake performance of freight wagons fitted with P10 cast iron or LL-blocks using limited testing (force measurement).

Railway applications - Electromagnetic compatibility - Part 2: Emission of the whole railway system to the outside world

This document is intended to define the electromagnetic environment of the whole railway system including urban mass transit and light rail systems. It describes the measurement method to verify the emissions and gives the cartography values of the fields most frequently encountered. This document specifies the emission limits of the whole railway system to the outside world. The emission parameters refer to the particular measuring points defined in Clause 5. Also, the zones above and below the railway system can be affected by electromagnetic emissions and particular cases need to be considered individually. For existing railway systems, it is assumed that compliance with the emission requirements of prEN 50121-3-1:2025, prEN 50121-3-2:2025, prEN 50121-4:2025 and prEN 50121-5:2025 will ensure the compliance with the emission values given in this part. This document gives emission limits for newly built railway systems (not yet in operation) with different characteristics (e.g. higher design speed of the line, static switching components) in comparison with existing railway systems.

Sensory analysis - Methodology - Duo-trio test (ISO/DIS 10399:2025)

ISO 10399 specifies a procedure for determining whether a perceptible sensory difference or similarity exists between samples of two products. The method is a forced-choice procedure. The method is applicable whether a difference exists in a single sensory attribute or in several attributes. The method is statistically less efficient than the triangle test (described in ISO 4120) but is easier to perform by the assessors. The method is applicable even when the nature of the difference is unknown (i.e. it determines neither the size nor the direction of difference between samples, nor is there any indication of the attribute(s) responsible for the difference). The method is applicable only if the products are fairly homogeneous. The method is effective for a) determining that either a perceptible difference results (duo-trio testing for difference), or a perceptible difference does not result (duo-trio testing for similarity) when, for example, a change is made in ingredients, processing, packaging, handling or storage, and b) for selecting, training and monitoring assessors. Two forms of the method are described: - the constant-reference technique, used when one product is familiar to the assessors (e.g. a sample from regular production); - the balanced-reference technique, used when one product is not more familiar than the other.
