This document specifies the standard test method useful to assess the performance of dust collection systems utilizing integrated fans (compact type dust collector), which shall be applied with or without flow control. Since the performance of this type of dust collector at being used for a certain period are different from those at the point of production, the performance test shall be carried out under a simulated used condition at the point of its production when the model has been newly developed and renewed. To produce a state of used condition at the point of its production, it is needed not only to accelerate but also simplify the affecting parameters, since performance of a dust collector system depends on many factors such as structure of the collector, filer element used, dust and carrier gas properties, operation method, operation time and so on. To satisfy these requirements, the black box concept, i.e., test dust collector will be operated with the same specification by the manufactures except test dust condition and the pulse interval during ageing stage of the test. Collection performance of dust, pressure drop, energy consumption for fan and pulse cleaning system and gas flow rate for without-gas-flow-rate-control system, shall be evaluated. Emission of PM10, PM2,5 and PM1 from the system may be added if necessary. This document is applicable to relatively small dust collection systems using cartridge filter as filtration media for dry dust collection. The performance obtained from this test does not guarantee the performance or certification of the system. This document is not intended to offer the superiority or inferiority of performance between dust collectors, but specifies a standard test method that provides users with performance under simulated conditions of use for a certain duration. It is recommended to publicize test condition and result on Web site (Home page) of manufacturer or on the product plaque of the system.

This document specifies calculation methods applicable to those companies using an electric arc furnace (EAF) to produce steel and having direct reduced iron (DRI) facilities within their premises. The present version of the standard allows user to also cover those particular cases of agglomeration of iron ore on site. It can be used to evaluate the total annual carbon dioxide (CO2) emissions and the emission factor of CO2 intensity of the entire steel production process. This document is applicable to plants producing mainly carbon steel. It includes boundary definition, material and energy flow definition and emission factor of CO2. Besides direct source import to the boundary, upstream and credit concept is applied to exhibit the plant CO2 intensity. This document supports the steel producer to establish CO2 emissions attributable to a site. Conversion to energy consumption and to consumption efficiency can be obtained using Annex A.

This document defines testing coupons and methods for the evaluation of the compression strength of AM lattice designs. The standardized test coupons will accommodate the application of a variety of lattice designs, while standardizing the evaluation method. This document is generally intended to be used in validation or verification activities for an additively manufactured component that incorporates a lattice or porous (non-solid) design. Details may include limits or requirements for minimum repeated elements and relative dimensions of the specimen. Note: Due to inherent variability across the manufacturing of AM components, evaluation methods are needed. Specifically, when an eventual component is intended to be subjected to compressive loads, a representative testing coupon is needed to represent the component to undergo destructive evaluation as a surrogate for the component itself.

This document describes procedures for determination of the compressive behaviour of ceramic matrix composite materials with continuous fibre reinforcement at elevated temperature in air, vacuum and inert gas atmospheres. This method applies to all ceramic matrix composites with a continuous fibre reinforcement, uni-directional (1D), bidirectional (2D) and multi-directional (xD, with x > 2), tested along one principal axis of reinforcement or off axis conditions for 2D and xD materials. This method also applies to carbon-fibre-reinforced carbon matrix composites (also known as carbon/carbon or C/C). Two cases of testing are distinguished: compression between platens and compression using grips.
