ČSN EN ISO 20815 This document describes the concept of production assurance within the systems and operations associated with exploration drilling, exploitation, processing and transport of petroleum, petrochemical and natural gas resources. This document covers upstream (including subsea), midstream and downstream facilities, petrochemical and associated activities. It focuses on production assurance of oil and gas production, processing and associated activities and covers the analysis of reliability and maintenance of the components. This includes a variety of business categories and associated systems/equipment in the oil and gas value chain. Production assurance addresses not only hydrocarbon production, but also associated activities such as drilling, pipeline installation and subsea intervention. This document provides processes and activities, requirements and guidelines for systematic management, effective planning, execution and use of production assurance and reliability technology. This is to achieve cost-effective solutions over the life cycle of an asset development project structured around the following main elements: - production assurance management for optimum economy of the facility through all of its life cycle phases, while also considering constraints arising from health, safety, environment, and quality; - planning, execution and implementation of reliability technology; - application of reliability and maintenance data; - reliability-based technology development, design and operational improvement. The IEC 60300-3 series addresses equipment reliability and maintenance performance in general. This document designates 12 processes, of which seven are defined as core production assurance processes and addressed in this document. The remaining five processes are denoted as interacting processes and are outside the scope of this document. The interaction of the core production assurance processes with these interacting processes, however, is within the scope of this document as the information flow to and from these latter processes is required to ensure that production assurance requirements can be fulfilled. The only requirement mandated by this document is the establishment and execution of the production assurance programme (PAP). It is important to reflect the PAP in the overall project management in the project for which it applies. This document recommends that the listed processes and activities be initiated only if they can be considered to add value.

ČSN ISO 48-1 Norma ISO 48-1 poskytuje návod pro stanovení tvrdosti u pryží a vulkanizovaných nebo termoplastických elastomerů, vysvětluje důležitost a význam stanovení tvrdosti jako klasifikačního parametru pro specifikaci výrobku, ale i pro diagnostické účely sledování průběhu stárnutí, kontaminace a pórovitosti. Norma ISO 48-1 je také důležitým zdrojem informací při výběru vhodné zkušební metody pro stanovení tvrdosti.

ČSN EN 14187-7 This document specifies a test method for determination of the resistance to flame of cold applied joint sealants for use in joints in roads, air fields and other trafficked areas. The resistance to flame of cold applied joint sealants is determined by subjecting it to the flame for a specified time.

ČSN EN 14187-5 This document describes a test method for determining the resistance to hydrolysis of cold applied joint sealants after treatment at elevated temperature and high humidity. Test specimen of the cold applied joint sealant is prepared in a round mould and treated for 14 days in an autoclave at elevated temperature and high humidity. The hardness of the test specimen is recorded before and after treatment at high humidity and temperature.

ČSN EN ISO 2376 Tento dokument stanovuje zkušební metody pro stanovení průrazného napětí a výdržného napětí anodických oxidových povlaků na hliníku a jeho slitinách na plochých nebo téměř plochých površích a na kruhovém drátu. Tyto metody jsou použitelné pro anodické oxidové povlaky používané především jako elektrické izolanty. Tyto metody nejsou použitelné pro povlaky v blízkosti řezaných hran, hran otvorů nebo ostrých změn úhlu, např. u lisovaných tvarů. POZNÁMKA 1: Průrazné napětí a výdržné napětí jsou ovlivněna relativní vlhkostí. POZNÁMKA 2: Popsané metody nedávají uspokojivé výsledky pro neutěsněné povlaky, protože jsou ovlivněny zejména vlhkostí.

ČSN EN 16796-4 This document specifies the method of fuel consumption measurement for rough-terrain variable-reach trucks as defined in ISO 5053-1, hereinafter referred to as trucks. It does not apply to slewing trucks having a movement of more than 5° either side of the longitudinal axis. This part is intended to be used in conjunction with EN 16796-1. Where the requirements of this part differ from that in part 1, requirements in this part 4 will take precedence.
