Scope: This standard defines specifications and describes test methods for measuring the performance of electronic digitizing waveform recorders, waveform analyzers, and digitizing oscilloscopes with digital outputs. The standard is directed towards, but not restricted to, general-purpose waveform recorders and analyzers.

Purpose: The main purpose of this standard is to help manufactures and users of waveform recorders have a well-defined set of specifications and test methods so they can understand, describe, and compare the performance of these recorders using a common language. Special applications can require additional manufacturer information and verification tests not covered in this standard. IEEE Std 1057-2017 has many similarities to IEEE Std 1241-2023. However, IEEE Std 1057-2017 applies to waveform recorders, while IEEE Std 1241-2023 applies to analog-to-digital converters.

Committee: IM/ST - TC9

Scope: This standard defines an Internet of Things (IoT) TRusted Area Networking (TRAN) architecture, designated as IoT-TRAN, for harmonizing IEEE Std 1451 sensor networks, IoT and Industrial IoT (IIoT) systems. IoT-TRAN provides an interoperability framework, including communication and semantics, allowing data sharing and interoperability in a trusted environment in which security of messages, agreements between devices, life-cycle management, and ownership of devices are granted over a cloud-oriented, federated, and decentralized network of things. The standard is built on top of the eXtensible Messaging and Presence Protocol (XMPP). A set of technologies is identified, allowing different devices to interoperate regardless of underlying communication technology. Each such technology is built as a standardized extension to this open protocol. A gateway to IoT-TRAN is an infrastructural component identified as a binding providing technology-specific devices reachability and real-time transparent conversion with other devices using their respective IoT protocols. As part of the IEEE Std 1451 standard family, features like Transducer Electronic Data Sheet (TEDS) and IEEE Std 1451.0 Universally Unique Identification (UUID) are leveraged in this standard to enhance the support of interfacing with IoT and IIoT systems.

Purpose: This standard defines a way to realize binding gateways between IoT, IIoT and IEEE Std 1451.0 devices to facilitate interoperability of otherwise non-interoperable IoT verticals. The standard addresses issues of security, scalability, and interoperability. This standard can provide significant cost savings and reduce complexity, and offer a data sharing approach leveraging current instrumentation and devices used in industry.

Committee: ST - TC-09

Scope: This standard defines a network protocol, the Precision Time Protocol (PTP), enabling accurate and precise synchronization of the real-time clocks of devices in networked distributed systems.

The protocol is applicable to systems where devices communicate via networks, including Ethernet. The standard allows multicast communication, unicast communication or both.

The protocol:

• Enables heterogeneous systems that include clocks of various inherent precision, resolution, and stability to synchronize to a grandmaster clock.
• Supports synchronization in the sub-microsecond range with minimal network bandwidth and local clock computing resources.
• Enhances support for synchronization to better than 1 nanosecond.
• Specifies how corrections for path asymmetry are made, if the asymmetry values are known. The grandmaster clock can be synchronized to a source of time external to the system, if time traceable to international standards or other source of time is required.
• Provides information for devices to compute Coordinated Universal Time (UTC) from the protocol distributed time, if the grandmaster clock is traceable to international standards and is able to access pending leap-second changes. Options are also provided to allow end devices to compute other time scales from the protocol distributed time scale.
• Defines timing domains in which system timing is consistent.
• Establishes the timing topology.
• Allows, via the default behavior of the protocol, simple systems to be installed and operated without requiring the administrative attention of users to determine the system timing topology.

The standard:

• Defines all needed data types, message formats, required computations, internal states, the behavior of devices with respect to transmitting, receiving, and processing protocol communications.
• Provides for the management of protocol artifacts in devices.
• Defines formal mechanisms for message extensions and the requirements for profiles that allow customization for specific application domains.
• Defines conformance requirements.
• Provides optional specifications for protocol security.
• Specifies requirements for mapping the protocol to specific network implementations and defines such mappings, including User Datagram Protocol (UDP)/Internet Protocol (IP versions 4 and 6), and layer-2 IEEE Std 802.3 Ethernet.
• Documents conditions under which this standard is backward compatible with IEEE Std 1588-2008 and IEEE Std 1588-2019.

Committee: ST - TC-09

Scope: This standard defines a simple and precise time transfer protocol called the Client Server Precision Time Protocol (CSPTP). CSPTP uses Precision Time Protocol (PTP) messages defined in IEEE Std 1588, to take advantage of timing support in network switches and routers. Therefore, CSPTP can achieve time transfer accuracies comparable to what can be achieved using PTP. However, CSPTP is logically isolated from PTP, and therefore can coexist with existing PTP networks. CSPTP allows clients to request timing information from any CSPTP server and allows the servers to operate without keeping state information on clients.

Scope: This standard defines the generic architecture and interfaces of a time card system, which constitutes a traceable source of time-of-day to heterogeneous systems that distribute and/or use that time. Additionally, this standard defines figures of merit that univocally characterize the relevant performance of the Time Card.

The Time Card provides a traceable time-of-day for systems directly attached to it, as well as networked distributed systems. Such systems include, but are not limited to, servers hosting the Time Card, and servers synchronized with the Time Card using such protocols as Precision Time Protocol (PTP) or Network Time Protocol (RFC Request for Comments) 5905.

This standard also defines the basic building blocks of the Time Card and their interfaces in order to allow modularization. The main building blocks include time source, local oscillator, and time processor.

Additionally, this standard defines interfaces between the Time Card and other systems. This includes physical interfaces that allow input and output of time-related signals. This also includes logical interfaces that are compatible with Portable Operating System Interface for UNIX (POSIX) and include for example an interface to share a Physical Hardware Clock (PHC). This allows sharing the time of day with other systems, as well as providing means for diagnostic and configuration. The definition of logical interfaces allows for a variety of Time Card's form factors (e.g. Peripheral Component Interconnect Express (PCIe)) while ensuring uniform support from the operating system.

Any device that complies with this standard provides performance figures that are obtained following the specifications of this standard. As such, different implementations of the Time Card can be easily compared in terms of performance.

Purpose: This standard provides 1) interoperability of different implementations of the Time Card with the systems, and their operating systems, that use it as the source of time-of-day; as such, to ensure a plug-and-play solution, 2) modular implementation of the Time Card to allow better customization to industry needs, and 3) univocal comparison of different implementations of the Time Card in terms of the relevant performance metrics.

Committee: RNIS - TC-45

Scope: This standard specifies minimum performance requirements and test methods for evaluating the performance of alarming personal radiation detectors (PRDs) for homeland security applications. The performance criteria contained in this standard provide means for verifying the capability of the PRDs to reliably detect changes above background levels of ionizing radiation fields and alert the user to these changes. The standard also specifies requirements and test methods for environmental, electromagnetic, and mechanical conditions that may affect the PRDs' response.

This standard does not apply to spectroscopic PRDs that have the ability to identify radionuclides. This standard does not apply to instruments that are primarily intended to provide a measurement of dose-equivalent, personal dose-equivalent, or ambient dose-equivalent rate.

Purpose: PRDs are pocket-sized battery-powered alarming electronic instruments that are worn on the body and used to detect photon-emitting, and optionally neutron-emitting, radioactive materials. PRDs have user-readable displays related to the intensity of radiation, but they are distinct from, and typically more sensitive than, electronic personal dosimeters, which are designed to measure the dose equivalent to workers occupationally exposed to radiation. This standard helps to ensure the proper functioning of PRDs thereby increasing trust in the device's measurement results.

The scope does not include the capabilities specific to nuclear safeguards, security of nuclear facilities, or nuclear forensics. Consideration of radiation detection instrumentation used for the PRND mission areas is part of the training requirements. Radiation detection instruments used primarily for other missions and capabilities (e.g., response and recovery mission areas) might have some applications for PRND mission areas and capabilities.

Purpose: This standard establishes minimum requirements, recommendations, and guidelines for organizations that develop, deliver and administer training programs in the PRND mission areas. The standard describes the skills specific to the PRND mission that are necessary for the core capability of PRND screening, search, and detection.
