Characteristics of anti-scatter grids used in X-ray equipment
Deals with the definitions, determination and indication of characteristics of anti-scatter grids used in X-ray equipment in order to reduce the incidence of scattered radiation produced particularly in the body of the patient, upon the X-ray image reception area and thus to improve the contrast of the X-ray pattern. Only linear grids are considered in this standard.
Magnetic materials. Part 2: Methods of measuring of magnetic, electrical and physical properties of ...
Describes the standard 25 cm Epstein frame and associated circuitry,
to be used for determining the B-H characteristic (both for d.c. and
for sinusoidal secondary voltage), specific total losses,
permeability, and reciprocal of complex permeability. Describes also
the standard methods for determining resistivity, coefficient of
surface insulation resistance, stacking factor, and…
Analogue signals for process control systems. Part 2: Direct voltage signals
Applicable to analogue direct voltage signals used in industrial process measurement and control systems. lt specifies ranges of analogue direct voltage signals and the signal common; it also deals with ripple content. The analogue direct voltage signal, unlike the analogue direct current signal specified in IEC 60381-1, is not intended for transmission over long distances. This standard does not…
Toroidal strip-wound cores made of magnetically soft material
Covers the dimensional and constructional characteristics for toroidal cores wound from strips of magnetically soft steel or alloy having thickness between 0.003 mm and 0.35 mm. Includes standard ranges of main dimensions and recommendations for strip thickness, core protection, marking and packing.
Primarily intended for the manufacturer. Not applicable to generators with pulsed sinusoidal outputs, television pattern generators, complex function generators, and generators for insulation resistance testing. Lays down a standard list of performance characteristics to be used for describing the performance of pulse generators. Defines which characteristics should be specified and standard test…
This standard states the minimum requirements for the preparation of materiel
for shipment by contractors and/or suppliers, for delivery to supply
distribution warehouses or supply centers for storage and subsequent issue, or
for direct delivery to customers when specified (par. 8.1).
Application of Hot Asphalt for Dampproofing or Waterproofing
Scope
1.1 This standard describes the procedures recommended for application of hot asphalt covered by CSA A123.7, when used in dampproofing or waterproofing footings, floors, walls and structural slabs.
Pitch, Emulsified Coal Tar, Mineral Colloid Type, Filled, for Coating
Bituminous Pavements
Scope
1.1 This standard applies to a filled mineral colloid type of coal tar pitch emulsion for use as a solvent-resistant coating applied by brush, spray or squeegee to bituminous pavements.
1.2 See par. 7.2 for the intended uses of this emulsion.
