Field devices are a key component in intelligent transport systems (ITS). Field devices include traffic signals, message signs, weather stations, traffic sensors, roadside equipment for connected ITS environments, etc. The ISO 26048 series defines data that can be used to manage field devices, including device configuration, control and monitoring. Field devices can be quite complex, necessitating the standardization of many data concepts for exchange. As such, the ISO 26048 series is divided into several individual parts. This document (ISO/TS 26048-1) introduces the ISO 26048 series, provides content that is normatively referenced in subsequent parts, and defines data that is applicable to the management of a wide range of field devices. The scope of the ISO 26048 series does not define the logic used by the management station, the underlying protocols used to exchange the defined data elements, or internal design of the field device. However, the ISO 26048 series does define functional requirements on the interface and assumes an interface based on an SNMPv3 environment as specified by ISO 15784-2. NOTE Many of the concepts defined in this document were derived from NTCIP 1103[ REF Reference_ref_11 \r \h 1 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000110000005200650066006500720065006E00630065005F007200650066005F00310031000000 ] and NTCIP 1201[ REF Reference_ref_12 \r \h 2 08D0C9EA79F9BACE118C8200AA004BA90B0200000008000000110000005200650066006500720065006E00630065005F007200650066005F00310032000000 ], however, the design has been updated to better address security concerns. It is expected that future versions of NTCIP will migrate to the design defined in this document.

This document describes a classification of non-metallic blast-cleaning abrasives for the preparation of steel substrates before application of paints and related products. It specifies the characteristics which are required for the complete designation of such abrasives. This document applies to abrasives supplied in the new or unused condition only. It does not apply to abrasives either during or after use. NOTE Although this document has been developed specifically to meet requirements for preparation of steelwork, the properties specified will generally be appropriate for use when preparing other material surfaces, or components, using blast-cleaning techniques. These techniques are described in ISO 8504-2.

IEC 60793-2-50:2025 is applicable to optical fibre categories B-652, B-653, B-654, B-655, B‑656 and B-657. A map illustrating the connection of IEC designations to ITU-T designations is shown in Table 1. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Three types of requirements apply to these fibres:
- general requirements, as defined in IEC 60793-2;
- specific requirements common to the class B single-mode fibres covered in this document and which are given in Clause 4;
- particular requirements applicable to individual fibre categories or specific applications, which are defined in Annex A to Annex F.
For some fibre categories (shown in the relevant family specifications), there are sub-categories that are distinguished on the basis of difference in transmission attribute specifications. The designations for these sub-categories are documented in the individual family specifications. Table 1 shows a map from the IEC designations to the ITU-T recommendations.

This document specifies computational methods for determining the acoustical source level of projectile sound and its one-third octave band spectrum, expressed as the sound exposure level for nominal mid-band frequencies from 12,5 Hz to 10 kHz. It also specifies a method on how to use this source level to calculate the sound exposure level at a receiver position. Results obtained with this document can be used as a basis for assessment of projectile sound from shooting ranges. Additionally, the data can be used to determine sound emission or immission from different types of ammunition and weapons. The prediction methods are applicable to outdoor conditions and straight projectile trajectories. Two computational methods are given to determine the acoustical source level: one for streamlined projectile shapes and one for non-streamlined shapes, such as pellets.
