Explosive atmospheres - Explosion prevention and protection - Part 2: Basic concepts and methodology for mining

This document specifies methods for explosion prevention and protection in mining by outlining the basic concepts and methodology for the design and construction of equipment, protective systems and components. This document applies to Group I equipment, protective systems and components intended for use in underground parts of mines and those parts of their surface installations at risk from firedamp and/or combustible dust. NOTE Detailed information on specific equipment, protective systems and components is contained in the relevant individual standards. Safety-relevant data regarding flammable materials and explosive atmospheres are required for the design and construction of the explosion protection measures. This document specifies methods for the identification and assessment of hazardous situations that may lead to explosions and describes the design and construction measures appropriate for the required safety. This is achieved by: — risk assessment; — risk reduction. The safety of equipment, protective systems, and components can be achieved by eliminating hazards and/or limiting the risk, i.e.: a) by appropriate design (without using safeguarding); b) by safeguarding; c) by information for use; d) by any other preventive measures. Measures in accordance with a) (prevention) and b) (protection) against explosions are dealt with in Clause 6 of this document; measures according to c) against explosions are dealt with in Clause 7 of this document. Measures in accordance with d) are not described in this document. They are dealt with in EN ISO 12100:2010, Clause 6. The preventive and protective measures described in this document will not provide the required level of protection unless the equipment, protective systems and components are operated in line with their intended use and are installed and maintained according to the relevant codes of practice or requirements. This document is applicable to any equipment, protective systems and components intended to be used in potentially explosive atmospheres. These atmospheres can arise from flammable materials processed, used or released by the equipment, protective systems and components or from materials in the vicinity of the equipment, protective systems and components and/or from the materials of construction of the equipment, protective systems and components. As shot firing can release potentially explosive atmospheres, this document is also applicable to the equipment used for shot firing, apart from the explosives and detonators. This document is applicable to equipment, protective systems and components at all stages of use. This document is not applicable to: — medical devices intended for use in a medical environment; — equipment, protective systems and components where the explosion hazard results exclusively from the presence of explosives or unstable chemical substances; — equipment, protective systems and components where the explosion can result from reaction of substances with oxidising agents other than atmospheric oxygen or by other hazardous reactions or conditions other than atmospheric conditions; — equipment intended for use in domestic and non-commercial environments where explosive atmospheres may only rarely be created and solely as a result of the accidental leakage of fuel gas; — personal protective equipment covered by Regulation (EU) 2016/425; the design and construction of systems containing desired, controlled combustion processes, unless they can act as ignition sources in potentially explosive atmospheres; — mines where firedamp and/or combustible dust are not naturally present and surface installations such as coal preparation plants, power plants, coke oven plants etc. in which an explosive atmosphere can be present, but which are not part of a coal mine. These are covered by EN 1127-1:2019.

Intelligent transport systems - ESafety - ECall end to end conformance testing for eCall HLAP in hybrid circuit switched/packet switched network environments

This document describes the key actors in the eCall chain of service provision in hybrid circuit switched/packet switched network environments as: 1) In-Vehicle System (IVS)/vehicle, 2) Mobile Network Operator (MNO), 3) Public Safety Answering Point (PSAP), and to provide conformance tests for actor groups 1) – 3). NOTE 1 Conformance tests are not appropriate nor required for vehicle occupants, although they are the recipient of the service. NOTE 2 Third party eCall systems (TPS-eCall) are not within the scope of this deliverable. This is because the core TPS-eCall standard (EN 16102) does not specify the communications link between the vehicle and the TPS service provider. NOTE 3 These conformance tests are partly based on the appropriate conformance tests from EN 16454 and CEN/prEN 17240. This deliverable therefore adapts and revises Conformance Test Protocols (CTP) from EN 16454 and CEN/prEN 17240 for hybrid circuit switched/packet switched network environments. This document complements EN 16454 and CEN/prEN 17240 and provides a suite of conformance tests for IVS equipment, MNOs and PSAPs, required to ensure and demonstrate compliance with CEN/prEN 17905. The scope covers conformance testing of new engineering developments, products and systems, and does not imply testing associated with individual installations in vehicles or locations.

Liquefied petroleum gases - Determination of dissolved residue - Gas chromatographic method using liquid, on-column injection

This European Standard specifies a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquefied petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass). This test method quantifies soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected. WARNING - This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
