This document addresses the essential elements and protocols needed for Space Traffic Coordination (henceforth referred to as “STC”). STC is critical to enhance the safety, stability, and sustainability of operations in the space environment.” STC enables flight safety, mitigates collision risk (for manoeuvrable spacecraft), and mitigates Radio Frequency Interference (RFI) for all phases of flight, spanning pre-launch safety assessment through manoeuvre plans, on-orbit collision avoidance, RFI mitigation support services, and mission disposal. This document is designed to enable the effective coordination of space traffic from pre-launch safety assessment to disposal at the end of operation through norms, the effective monitoring, and mitigation of collision risk and RFI. The document is designed for state actors, spacecraft designers, spacecraft operators, and STC system developers and operators. While this document applies to the range of orbital regions in which current STC and SSA systems can effectively track, monitor, and provide actionable data for space objects, it is envisioned that this document is generally applicable to all orbit regimes and for orbits around all central bodies and barycentres.

 

This document specifies the requirements for the inspection, installation and requalification of high pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles. This document is applicable to high pressure cylinders designed and manufactured in accordance with the requirements of ISO 11439.

This part of ISO 14577 specifies the method of dynamic linear elastic instrumented indentation test for determination of indentation hardness and indentation modulus of materials showing elasticplastic behaviour when oscillatory force or displacement is applied to the indenter while the load or displacement is held constant at a prescribed target value or while the indenter is continuously loaded to a prescribed target load or target depth.

 

This document concerns human exposure to whole-body vibration and shock in buildings with respect to the comfort and annoyance of the occupants based on both measurements and simulations. It specifies a method for measurement and evaluation, comprising the determination of the measurement direction and measurement location. It defines in Annex A the frequency weighting Wm which is applicable in the frequency range 1 Hz to 80 Hz where the posture of an occupant does not need to be defined. Whilst it is often the case that a building will be available for experimental investigation, many of the concepts contained within this document would apply equally to a building in the design process or where it will not be possible to gain access to an existing building. In these cases, reliance will have to be placed on the prediction of the building response by some means. This document does not provide guidance on the likelihood of structural damage, which is discussed in ISO 4866[3]. Further, it is not applicable to the evaluation of effects on human health and safety. Acceptable magnitudes of vibration are not stated in this document, but guidance is provided in Annex C in the form of exposure-response curves for the estimation of annoyance when vibration originates from various sources, including railway, construction activities and blasting.

 

This document specifies the classification for respiratory infection prevention devices (RIPDs). RIPDs are intended to reduce the emission of infective agents from the user’s airways into the environment, and also reduce exposure to the user from inhalation of infective agents. RIPDs are intended for use by everybody regardless of facial morphology or ability.

 

This document provides additional terms and definitions to those written in the Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) or the Regulations concerning the International Carriage of Dangerous Goods by Rail (RID), appearing as Appendix C to the Convention concerning International Carriage by Rail (COTIF). This document forms part of series of documents prepared by CEN/TC 296 regarding the transport of dangerous goods. The series supports the proper application of the ADR and RID. This document is applicable to tanks used for the transport of dangerous goods. This document does not apply to carriage in bulk of dangerous goods. For convenience, Annex A (informative) repeats some horizontal definitions taken from ADR and RID 2025 chapter 1.2, and Annex B (informative) repeats some definitions from ADR and RID 2025 chapter 6.7, specific to portable tanks. NOTE The ADR and RID are updated on a regular basis, therefore Annexes A and B might become out of date. For outdated definitions, the RID/ADR take precedence. Annexes C, D and E (informative) provide alphabetical trilingual indexes of terms in English, French and German where the key is English, French and German respectively. Annex F (normative) is a schematic diagram of tank openings and closures according to the tank code.

This document specifies a routine method for determining the organic matter and the ash content of soil improvers and growing media. NOTE The loss on ignition (LOI) is often used as an estimate for the content of organic matter in the sample. Inorganic substances or decomposition products (e.g. H2O, CO2, SO2, O2) are released or absorbed and some inorganic substances are volatile under the reaction conditions. Thus, a conversion to the organic carbon content is not possible.

 

This document specifies an instrumental method for the routine determination of electrical conductivity in a water extract of a soil improver or growing medium.
