This international standard deals with the classification of fan efficiency for all fan types driven by motors of nominal rating 0.125kW and above. This standard may be used by legislators or regulatory bodies for defining future energy saving targets. This applies to the fan (driven) only but not to the system (finished Original Equipment Manufacturer’s product, e.g. box fans and roof fans or ventilation system) in which it is installed.

for compressed, liquefied and dissolved gases.

quenched and tempered steel cylinders and tubes  with an actual tensile strength Rma ≥ 1 100 MPa.

It is not applicable to:

cylinders and tubes with Rma, max > 1 300 MPa for diameters > 140 mm and guaranteed wall thicknesses a¢ ≥ 12 mm and

cylinders and tubes with Rma, max > 1 400 MPa for diameters ≤ 140 mm and guaranteed wall thicknesses a¢ ≥ 6 mm,

because beyond these limits, additional requirements can apply.

This standard covers the general description of benchmarking test piece geometries along with quantitative and qualitative measurements to be taken on the benchmarking test piece(s) to assess the performance of additive manufacturing (AM) systems. This performance assessment may serve the two following purposes: AM system capability evaluation, and an AM system calibration. The benchmarking test piece(s) is primarily used to quantitatively assess the geometric performance of an AM system. The standard describes a suite of test geometries, each designed to investigate one or more specific performance metrics, and several example configurations of these geometries into test piece(s). The standard prescribes quantities and qualities of the test geometries to be measured, but does not dictate specific measurement methods. Various user applications may require various grades of performance. This standard discusses examples of feature configurations, as well as measurement uncertainty requirements, to demonstrate low and high grade examination and performance. This standard does not discuss a specific procedure or machine settings for manufacturing a test piece although these should be recorded as per ASTM F2971 and other relevant process specific specifications.

This International Standard establishes and defines terms used in additive manufacturing (AM) technology, which applies the additive shaping principle and thereby builds physical three-dimensional (3D) geometries by successive addition of material.

The terms have been classified into specific fields of application.

New terms emerging from the future work within ISO/TC 261 and ASTM F42 will be included in upcoming amendments and overviews of this International Standard.

This International Standard specifies safety requirements for wetlaid-nonwoven machinery. It defines the design according to safety regulations for wetlaid nonwoven machines and their components.

The requirements of this International Standard applies to wetlaid nonwoven machines, including approach flow system, headbox, wire section and jet head, hydroentangling unit, dryer, finishing, Quality Control System (QCS), winder, drives and control system. It deals with all significant hazards, hazardous situations and hazard events relevant to wetlaid nonwoven machines, when used as intended and under the conditions foreseen by the manufacturer.

This document does not deal with pressure hazards in steam-heated drying cylinders.

NOTE          National laws (e. g. for Europe Directive 2014/68/EU) gives essential safety requirements for equipment under pressure.

This document does not apply to machines, which are intended for use in explosive atmospheres.

This Standard is not applicable to wetlaid nonwoven machines which have been manufactured before the date of publication of this Standard.

This International Standard specifies a noise test code for determining, efficiently and under standardized conditions, the noise emission characteristics of portable, hand held, combustion engine powered forest and garden machines, including chain-saws, brush-cutters, grass-trimmers, edgers, pole-mounted powered pruners, hedge-trimmers and garden blowers/vacuums/knapsack mist blowers. Noise emission characteristics include the A-weighted emission sound pressure level at the operator position and the A-weighted sound power level.

This document specifies requirements and gives recommendations on the management of geohazard risks of pipeline during the design, construction and operational periods.

This document shall apply to all operators and pipeline systems (existing and proposed/under construction), unless the operator can clearly demonstrate why the document should not apply.

This document applies to onshore gathering and transmission pipelines used in the petroleum and natural gas industries[1].

This document is applicable to all reasonable and credible natural hazards and hazards induced by human activity that manifest similarly to natural hazards, collectively referred to as “Geological Hazards” or “Geohazards”. Geohazards covered by this document include, but are not limited to (not given in order of significance):

—    mass wasting processes, including landslides, rockfalls, debris flows, avalanches, and similar processes whether naturally occurring or anthropogenic;

—    land subsidence and/or sinkhole formation, whether naturally occurring such as from dissolution of salt or carbonate rock formations (karst formation) or human caused, such as from underground mining or withdrawal of subsurface fluids such as groundwater and oil and gas;

—    seismic hazards, such as ground shaking, fault rupture, liquefaction, flow failures and lateral spreading or associated secondary effects, such as seismically triggered landslides;

—    volcanic hazards, such as lahars, pyroclastic flows, lava flows, dam break, and volcanically induced seismicity (excluding ashfall), where such hazards can be reasonably predicted;

—    hydrologic processes, such as flooding, vertical scour of river bottoms, channel migration and bank erosion, channel avulsion, rapid lake drainage;

—    permafrost/periglacial processes and geothermal effects, such as frost heave or thaw settlement;

—    surface and backfill erosion;

—    expansion or collapsing process caused by expansive and collapsible soils, such as glaciomarine clays, collapsible loess, etc.

This document does not cover atmospheric effects such as:

—    high winds induced from hurricanes and tornadoes and similar storms, except where such events are reasonably predictable and will induce geohazards such as landslides, erosion, etc.,

—    lightning,

—    forest or brush fires,

—    ashfall from volcanic eruptions,

—    tsunamis induced by seismic hazards.

Furthermore, this document does not cover so-called cascading events, where one remote event leads to a chain of events that eventually induces a geohazard near the pipeline. Only geohazards that directly affect the pipeline or RoW are covered.

 

[1] Piping and pipelines within well-defined plants and facilities, such as pump or compressor stations, processing facilities or refineries are not covered by this document. It is assumed that the facility site as a whole will be subject to a separate geohazard assessment to evaluate applicable natural and man-made hazards. Nevertheless, this document may provide useful guidance for assessing the geohazard threat to facilities, including the pipelines within the facility.
