Central safety power supply systems
This document specifies the general requirements for central power supply systems for an independent energy supply to essential safety equipment. This document covers systems that are permanently connected to AC supply voltages not exceeding 1 000 V and use batteries as an alternative power source. Central safety power supply systems are intended to ensure energy supply to emergency escape lighting in the event of normal supply failure and could be suitable for energizing other essential safety equipment, for example: - electric circuits of automatic fire extinguishing installations; - paging systems and signalling safety installations; - smoke extraction equipment; - carbon monoxide warning systems; - special safety installations related to specific buildings, e.g. high-risk areas. The power supply of CPS systems is expected to be dedicated only to the essential safety equipment, and not for other type of loads such as general purpose IT or industrial systems etc. Combinations of the aforementioned safety equipment types can be used together on the same central safety power supply s

Unfired pressure vessels - Part 10: Additional requirements for pressure vessels of nickel and nickel alloys
This Part 10 of this document specifies requirements for unfired pressure vessels and their parts made of nickel and nickel alloys (see 3.1) in addition to the general requirements for unfired pressure vessels under EN 13445-1:2026, EN 13445-2:2026, EN 13445-3:2026, EN 13445-4:2026 and EN 13445-5:2026. NOTE Cast materials are not included in this version. Details regarding cast materials will be subject to an amendment to or a revision of this document.

Unfired pressure vessels - Part 1: General
This document defines the terms, definitions, quantities, symbols and units that are used throughout the EN 13445 series and gives general information on the design and manufacturing of vessels under this standard. It also contains instructions on how to use the standard (Annex A) as well as an index which covers the whole standard (Annex B). This information is aimed to aid users of the EN 13445 series. This document applies to unfired pressure vessels with a maximum allowable pressure greater than 0,5 bar gauge but may be used for vessels operating at lower pressures, including vacuum. This document is not applicable to pressure vessels of the following types: - vessels of riveted construction; - vessels of lamellar cast iron or any other materials not included in Parts 2, 6, or 8 of the standard; - multilayered, autofrettaged or pre-stressed vessels. This document can be applied to the following pressure vessels, provided that account is taken of additional and/or alternative requirements resulting from the hazard analysis and from rules or instructions specific for: - transportab
