Acoustics — Noise from shooting ranges — Part 2: Calculation of muzzle blast
This document specifies a computational method (in line with ISO 17201-4) for estimating the acoustic source data of muzzle blast and explosions on the basis of non-acoustic data for firearms with calibres less than 20 mm and explosions less than 50 g TNT equivalent.
This document addresses those cases where no source measurements exist. This document can also be used as an interpolation method…
This document specifies the general characteristics of grooved pins, made of steel and stainless steel, with nominal diameters 1 mm to 25 mm.
These grooved pins are designed to fulfil the main following functions, due to the elastic fit behaviour of the grooves:
— locking of two (or more) parts,
— positioning or guiding,
— relative rotation of the assembled parts.
Cereals and cereal products — Determination of 17 mycotoxins by ultra-high-performance liquid chroma...
This document specifies a method for the quantitative determination of 17 mycotoxins in cereals and cereal products (e.g. wheat, maize, husked rice, rice and their products) using ultra-high-performance liquid chromatography and tandem mass spectrometry method (UHPLC-MS/MS).
The 17 mycotoxins are aflatoxin B1, aflatoxin B2, aflatoxin G1, aflatoxin G2, deoxynivalenol, nivalenol, deoxynivalenol-3-…
Electronic fee collection — Evaluation of on-board and roadside equipment for conformity to ISO 1314...
This document specifies the test suite structure (TSS) and test purposes (TP) to evaluate the conformity of on-board equipment (OBE) and roadside equipment (RSE) to ISO 13141.
It provides a basis for conformance tests for dedicated short-range communication (DSRC) equipment to support interoperability between different equipment supplied by different manufacturers.
ISO 13141 specifies…
Aciers et fontes — Détermination du carbone total — Méthode par absorption dans l'infrarouge ap...
Le présent document spécifie une méthode par absorption dans l'infrarouge après combustion dans un four à induction pour la détermination du carbone total dans les aciers et les fontes.
La méthode est applicable aux teneurs en carbone comprises entre 0,003 % (en masse) et 4,5 % (en masse).
Céramiques techniques — Propriétés mécaniques des composites céramiques à haute température — Déterm...
Le présent document spécifie les conditions de détermination des propriétés en traction axiale de tubes composites à matrice céramique (CMC) avec renfort de fibres continues à température élevée sous air, sous vide et dans les atmosphères de gaz inerte. L’applicabilité du présent document est spécifique aux composites à matrice céramique tubulaire dont la géométrie est étroitement liée à la…
Electric vehicle battery swap system - Part 2: Safety requirements
IEC 62840-2:2025 provides the safety requirements for a battery swap system, for the purposes of swapping swappable battery system (SBS)/handheld-swappable battery system (HBS) of electric vehicles. The battery swap system is intended to be connected to the supply network. The power supply is up to 1 000 V AC or up to 1 500 V DC in accordance with IEC 60038. This document also applies to battery…
