magnetic field strength

Voorbeeldzinnen

1. Magnetic field strength, H (A/m)
2. Magnetic field strength is a vector quantity (H), which, together with the magnetic flux density, specifies a magnetic field at any point in space.
3. In free space and in biological materials, magnetic flux density and magnetic field strength can be interchanged using the equivalence 1 A/m = 4π 10—7 T.
4. Magnetic field strength is a vector quantity (H), which, together with the magnetic flux density, specifies a magnetic field at any point in space. It is expressed in amperes per metre (A/m).
5. transponders applying FDX-B technology shall have a minimum activating magnetic field strength less than or equal to 1,2 A/m, as measured according to the ISO standard 24631-3, part 7.6.4 “Minimum activating magnetic field strength in FDX-B mode” and shall develop a modulation amplitude equivalent to 10 mV as measured according to the ISO standard 24631-3, part 7.6.6 “Modulation amplitude in FDX-B mode”, at a magnetic field strength less than or equal to 1,2 A/m.’
6. transponders applying HDX- technology shall have a minimum activating magnetic field strength less than or equal to 1,2 A/m, as measured according to the ISO standard 24631-3, part 7.6.5 “Minimal activating magnetic field strength in HDX mode” and shall develop a modulation amplitude equivalent to 10 mV as measured according to the ISO standard 24631-3, part 7.6.7 “Modulation amplitude in HDX mode” at a magnetic field strength less than or equal to 1,2 A/m;
7. ‘action values’: the magnitude of directly measurable parameters, provided in terms of electric field strength (E), magnetic field strength (H), magnetic flux density (B) and power density (S), at which one or more of the specified measures in this Directive must be undertaken.
8. N.B.: The "superconductive" state of a material is individually characterised by a "critical temperature", a critical magnetic field, which is a function of temperature, and a critical current density which is, however, a function of both magnetic field and temperature. "Super High Power Laser" ("SHPL") (6) means a "laser" capable of delivering (the total or any portion of) the output energy exceeding 1 kJ within 50 ms or having an average or CW power exceeding 20 kW. "Superplastic forming" (1 2) means a deformation process using heat for metals that are normally characterised by low values of elongation (less than 20 %) at the breaking point as determined at room temperature by conventional tensile strength testing, in order to achieve elongations during processing which are at least 2 times those values.

"Symmetric algorithm" (5) means a cryptographic algorithm using an identical key for both encryption and decryption. N.B.A common use of "symmetric algorithms" is confidentiality of data.
10. "Superalloys" (2 9) means nickel-, cobalt- or iron-base alloys having strengths superior to any alloys in the AISI 300 series at temperatures over 922 K (649 °C) under severe environmental and operating conditions. "Superconductive" (1 3 6 8) means materials, i.e., metals, alloys or compounds, which can lose all electrical resistance, i.e., which can attain infinite electrical conductivity and carry very large electrical currents without Joule heating.
