And on the other hand, it specifies requirements for the mobile manufacturing units and their accessories as a contribution to the guarantee of the conformity of explosives produced in on-site conditions with no access to a laboratory.
This document gives guidance on also basic requirements for explosives loading equipment.
This document does not apply to the preparation of multi-component explosives as they neither require manufacturing equipment nor mechanical loading.
NOTE 1   This document does not address the requirements of the transport of dangerous goods regulations.
NOTE 2   This document does not address the requirements established in Directive 2006/42/EC (Machinery).

IEC 60794-1-130:2025 describes test procedures to evaluate the coefficient of dynamic friction of the sheathing material of a cable when pulled over or between other cables. Methods E30A and E30B evaluate the coefficient of friction between cables for when either a cable is pulled over the top of other cables (drum test) or when pulling a cable between other cables of the same shape (flat plate test). This document applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. Throughout the document, wording "optical cable" can also include optical fibre units and microduct fibre units. This first edition cancels and replaces Method E24 of the first edition of IEC 60794‑1‑21 published in 2015, Amendment 1:2020. This edition constitutes a technical revision.

This document provides a method for quantification of marker peptide of type I collagen which was purified products extracted from bovine tissues with liquid chromatography - tandem mass spectrometry (LC-MS/MS). The method described in this document is intended to be used for marker peptide detection of purified bovine type I collagen which will be used for constructing tissue-engineered medical products (TEMPs) or other collagen-based biomaterials, for product quality control. This method also can be used for qualitative analysis and quantitative detection of bovine-specific and/or type I-specific collagen in the samples mixed with other animal sources and/or other type collagen. This document does not exclude other possible methods for quantifying type I collagen, such as hydroxyproline quantification, that can evaluate the total amount of collagen regardless of type. NOTE 1 The collagen has been known there are greater than 28 types and with the different property in each one. This document focuses on the quantification of marker peptide of purified bovine type I collagen. Type I collagen isolated from skin, tendon, bone, etc., can contain other types of collagen, for example, type III and type V. And type I collagen can be sourced from bovine, swine, etc. For quantification of other types of collagens or type I collagen sourced from other species of animals can use this document as a template, but need to design collagen type-specific or/and animal species-specific characteristic peptides for LC-MS/MS method, as well as optimize the determination conditions. NOTE 2 For quantification of the collagen marker peptide of scaffold which combined with other materials, or type I collagen contained in ECM materials of tissues or type I collagen-based regenerative tissues, can refer to this document, but need to isolate or/and purify the type I collagen with a reasonable and verified method at first (9,10), and then quantify it by referring to the method provided in this document.

IEC 61643-11:2025 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are intended to be connected to AC power circuits and equipment rated up to 1 000 V RMS, the preferred frequencies taken into account in this document are 50/60 Hz. Other frequencies are not excluded. Performance and safety requirements, tests and ratings are specified in this document. These devices contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents. The test requirements provided by this document are based on the assumption that the SPD is connected to an AC power circuit fed by a power source providing a linear voltage-current characteristic. When the SPD is to be connected to a different kind of source or to a different frequency, careful consideration is required. This mainly applies with regard to system and fault conditions to be expected in such a system (e.g. expected short circuit current, TOV-stresses). This document can apply for railway applications, when related product standards do not exist for that area or for certain applications. Based on a risk assessment it might not be necessary to apply all requirements of this document to SPDs designed for specific power applications only, e.g. circuits with a low power capability, circuits supplied by nonlinear sources, circuits with protective separation from the utility supply. NOTE 1 More information on risk assessment is provided in IEC Guide 116. NOTE 2 Other exclusions based on national regulations are possible. This edition includes the following significant technical changes with respect to the previous edition: a) Specific requirements for SPDs for AC applications are now contained in this document, whereas the common requirements for all SPDs are now contained in IEC 61643-01; b) Clarification on test application either to a complete SPD, to a "mode of protection", or to a complete "SPD assembly"; c) Additional measurement of voltage protection level on "combined modes of protection" between live conductors and PE; d) Additional duty test for T1 and T2 SPDs with follow current to check variation of the follow current value at lower impulse currents; e) Modified and amended short circuit current test requirements to better cover up to date internal SPD disconnector technologies; f) Improved dielectric test requirements for the SPD's main circuits and added dielectric test requirements for "electrically separated circuits"; g) Additional clearance requirements for "electrically separated circuits". The requirements of this document supplement, modify or replace certain of the general requirements contained in IEC 61643-01 and shall be read and applied together with the latest edition of IEC 61643-01, as indicated by the undated normative reference in Clause 2 of this document.
