This document specifies conditions for the determination of circumferential mechanical properties of ceramic matrix composite (CMC) tubes with continuous fibre-reinforcement at room temperature on C-ring specimen under diametric compression. This document is specific to the tubular geometries because fibre architecture and specimen geometry factors in composite tubes are distinctly different from those in flat specimens. This test method is straightforward to carry out and low-material consumption. It provides information on the circumferential Young modulus, the mechanical response and the ultimate fracture force. If the ultimate fracture occurs within the linear elastic domain, then the compressive strength can be determined from the corresponding ultimate fracture force. The information can be used for material development, control of manufacturing (quality insurance), material comparison, characterization, reliability and design data generation for tubular components. This document addresses, but is not restricted to, various suggested test piece fabrication methods. This document is primarily applicable to ceramic matrix composites tube with a continuous fibrous-reinforcement: unidirectional (1D, filament winding and tape lay-up), bidirectional (2D, braid and weave) and multi-directional (xD, with x >2).

This document provides guidance on procedures for commissioning a ballast water management system (BWMS) using electrolytic methods following installation on board a ship. It specifies safety measures, procedures for commissioning (including installation inspection, function test, training of ship's crew) and a commissioning test in accordance with BWM.2/Circ.70/Rev.1, as may be revised. This commissioning process ensures the health and safety of personnel involved in commissioning, verifies proper function and operation, and provides procedures for sampling and analysis. This document also provides guidance on the documentation of commissioning. This document is mainly focused on the commissioning of a BWMS using electrolytic methods after initial installation on board a ship, but it can also apply to other necessary surveys of a BWMS and readiness evaluation of land-based or shipboard testing for type approval required by IMO and/or a port state.

 

This document defines the basic terms relating to the design and operation of reciprocating internal combustion (RIC) engines. Further terms relating to components and systems of RIC engines are defined in ISO 7967 (all parts), and performance is defined in ISO 15550, ISO 14396 and in ISO 3046 (all parts).

 

This document specifies the testing conditions to assess the treatment performances of greywater systems. Excluded from the scope of this document are: - the testing of rainwater harvesting systems; - the testing of systems for direct use as mentioned in EN 16941–2 "On-site non-potable water systems - Part 2: Systems for the use of treated greywater"; - the testing of blackwater treatment systems; - the testing of wastewater treatment plant.

 

 

ISO 14644-13:2017 gives guidelines for cleaning to a specified degree on cleanroom surfaces, surfaces of equipment in a cleanroom and surfaces of materials in a cleanroom. Under consideration are all surfaces (external or internal) that are of interest. It provides guidance on the assessment of cleaning methods for achieving the required surface cleanliness by particle concentration (SCP) and surface cleanliness by chemical concentration (SCC) classes and which techniques should be considered to achieve these specified levels. The appropriateness of cleaning techniques will make reference to the cleanliness classes and associated test methods found in ISO 14644-9 and ISO 14644-10. The following matters of general guidance will be provided: - expected surface cleanliness levels; - suitability of cleaning methods; - compatibility of surfaces with the cleaning technique; - assessment of cleaning appropriateness. The following will be excluded from this document: - classification of cleaning methods; - product produced within a cleanroom; - specific surface-related cleaning methods; - detailed description of cleaning mechanisms, methods and procedures of various cleaning methods; - detailed material characteristics; - description of damage mechanisms by cleaning processes and time-dependent effects; - references to interactive bonding forces between contaminants and surfaces or generation processes that are usually time-dependent and process-dependent; - other characteristics of particles such as electrostatic charge, ionic charges, etc.; - chemical reactions between molecular contaminants and surfaces; - microbiological aspects of surface cleanliness; - radioactive aspects of contamination; - health and safety considerations; - environmental aspects such as waste disposal, emissions, etc.; - selection and use of statistical methods.

 

ISO 14644-14:2016 specifies a methodology to assess the suitability of equipment (e.g. machinery, measuring equipment, process equipment, components and tools) for use in cleanrooms and associated controlled environments, with respect to airborne particle cleanliness as specified in ISO 14644-1. Particle sizes range from 0,1 µm to equal to or larger than 5 µm (given in ISO 14644-1). NOTE Where regulatory agencies impose supplementary guidelines or restrictions, appropriate adaptation of the assessment methodology can be required. The following items are not covered by this ISO 14644-14:2016: - assessment of suitability with respect to biocontamination; - testing for suitability of decontamination agents and techniques; - cleanability of equipment and materials; - requirements on design of equipment and selection of materials; - physical properties of materials (e.g. electrostatic, thermal properties); - optimizing performance of equipment for specific process applications; - selection and use of statistical methods for testing; - protocols and requirements for local safety regulations.

 

This document gives guidance on specific procedures to be considered when carrying out vibration diagnostics of various types of machine sets in hydraulic power generating and pump-storage plants (hydropower units). It is intended to be used by condition monitoring practitioners, engineers and technicians and provides a practical step-by-step vibration-based approach to fault diagnosis. In addition, it includes a number of examples for a range of machine and component types and their associated fault symptoms.

 

This document specifies a method for determining the ultimate aerobic biodegradability of plastic materials under controlled composting conditions by gravimetric measurement of the amount of carbon dioxide evolved. The method is designed to yield an optimum rate of biodegradation by adjusting the humidity, aeration and temperature of the composting vessel. The method applies to the following materials: — natural and/or synthetic polymers and copolymers, and mixtures of these; — plastic materials that contain additives such as plasticizers or colorants; — water-soluble polymers; — materials that, under the test conditions, do not inhibit the activity of microorganisms present in the inoculum. If the test material inhibits microorganisms in the inoculum, another type of mature compost or pre-exposure compost can be used.

 

 

The scope of the new standard will cover the different types of repair and rehabilitation that can be undertaken on / or with clay pipes.

The scope will also cover repair and rehabilitation of pipes laid using the open trench installation method. This will include replacement of socketed joints and replacement or repair of pipes, junctions and manholes. The scope will again cover the products that can be used, their performance criteria and testing methods after installation.

 

This European Standard specifies a method for the determination of nitrogen in soil improvers and growing media. The dry combustion method was developed originally as a manual method by Dumas. Its application is improved greatly due to the use of modern automated equipment and is applicable to all forms of nitrogen.
