This document defines terms used to describe external limb prostheses. The terms related to the amputation level used to in this document are described in ISO 8549‑4. The types of component used in the construction of prostheses are classified and described in ISO 13405‑1, ISO 13405‑2 and ISO 13405‑3. For the purposes of this document, the abbreviated term ‘prosthetics’ and its derivatives only…

This document specifies a code of practice dealing with unplasticized polyamide (PA-U) pipes and fittings for buried pipeline systems outside buildings and designed to transport gaseous fuels (as defined in ISO 16486-1, e.g. methane, LPG, manufactured gas and hydrogen) within the temperature range –20 °C to +40 °C. This document also gives appropriate temperature-related requirements. The code of…

IEC 61439-4:2023 defines the specific requirements of ACS as follows: - assemblies for which the rated voltage does not exceed 1 000 V in case of AC or 1 500 V in case of DC; - assemblies where the nominal primary voltage and the nominal secondary voltage of transformers incorporated in ACS are within the limits specified above; - assemblies intended for use on construction sites, both indoors…

This document defines general terms and film growth processes for atomic layer deposition (ALD). ALD technique is classified into conventional time separated ALD and spatial ALD according to the separation between sequential surface reactions of precursors on substrate. Besides planar substrate, ALD can be used for coating on micro-nano particles, which is developed as powder ALD. Some energy…
