This part of IEC 60118 specifies methods for measurement of the bone conduction hearing aids characteristics.

The methods described will produce a suitable basis for the exchange of information or for direct comparison of the electroacoustical characteristics of bone conduction hearing aids. These methods are chosen to be practical and reproducible and are based on selected fixed parameters.

The results obtained by the methods specified in this standard express the performance under the conditions of the measurement but will not necessarily agree exactly with the performance of the hearing aid under practical conditions of use.

This document defines methods of measurement of characteristics of bone conduction hearing aids both:

transcutaneously coupled devices measured on a mechanical coupler, meeting requirements of IEC 60318-6,

bone coupled/bone anchored devices measured on a mechanical coupler configured as a skull simulator.

NOTE 1 A skull simulator is a mechanical coupler designed to present a specific mechanical impedance to a vibrator coupled with a mechanical coupling

Though the number of measurements covered by this part of IEC 60118 is limited, it is not intended that all measurements described herein are mandatory.

NOTE 2 Throughout this document all sound pressure levels specified are referred to 20 µPa. When appropriate, sound pressure level will be abbreviated to SPL.

This standard applies to all kinds of passive dosimetry systems that are used for measuring

the personal dose equivalent Hp(10) (for individual whole body monitoring),

the personal dose equivalent Hp(3) (for individual eye lens monitoring),

the personal dose equivalent Hp(0,07) (for both individual whole body skin and extremity monitoring),

the ambient dose equivalent H*(10) (for workplace and environmental monitoring),

the directional dose equivalent H'(3) (for workplace and environmental monitoring), or

the directional dose equivalent H'(0,07) (for workplace and environmental monitoring).

This standard applies to dosimetry systems that measure external photon and/or beta radiation in the dose range between 0,01 mSv and 10 Sv and in the energy ranges given in Table 1. All the energy values are mean energies with respect to the prevailing dose quantity. The dosimetry systems usually use electronic devices for the data evaluation and thus are often computer controlled.

Table 1 – Mandatory and maximum energy ranges covered by this standard

Measuring quantity

Mandatory energy range for photon radiation

Maximum energy range for testing photon radiation

Mandatory energy range for beta-particle radiationa

Maximum energy range for testing beta-particle radiationa

Hp(10), H*(10)

80 keV to 1,25 MeV

12 keV to 10 MeV

Hp(3), H'(3)

30 keV to 250 keV

8 keV to 10 MeV

0,8 MeVd

0,7 MeVb to 1,2 MeVd

Hp(0,07), H'(0,07)

30 keV to 250 keV

8 keV to 10 MeV

0,8 MeVd

0,07 MeVc to 1,2 MeVd

a    The following beta radiation source are suggested for the different mean energies: For 0,06 MeV: 147Pm; for 0,8 MeV: 90Sr/90Y; for 1,2 MeV: 106Ru/106Rh.

b    For beta-particle radiation, an energy of 0,7 MeV is required to reach the radiation sensitive layers of the eye lens in a depth of about 3 mm (approximately 3 mm of ICRU tissue).

c    For beta-particle radiation, an energy of 0,07 MeV is required to penetrate the dead layer of skin of 0,07 mm (approximately 0,07 mm of ICRU tissue).

d    0,07 MeV, 0,7 MeV and 1,2 MeV beta mean energy are almost equivalent to an Emax of 0,225 MeV, 2,27 MeV and 3,54 MeV, respectively.

 

 

NOTE 1 In this standard, “dose” means dose equivalent, unless otherwise stated.

NOTE 2 For Hp(10) and H*(10) no beta radiation is considered. Reasons: 1) Hp(10) and H*(10) are a conservative estimate for the effective dose which is not a suitable quantity for beta radiation. 2) No conversion coefficients are available in ICRU 56, ICRU 57 or ISO 6980-3.

NOTE 3 The maximum energy ranges are the energy limits within which type tests according to this standard are possible.

NOTE 4 Direct ion storage (DIS) dosemeters are covered in this standard as they are often operated without an online display but a separate reader.

The test methods concerning the design (Clause 8), the instruction manual (Clause 9), the software (Clause 10), environmental influences (Clause 13), electromagnetic influences (Clause 14), mechanical influences (Clause 15), and the documentation (Clause 16) are independent of the type of radiation. Therefore, they can also be applied to other dosimetry systems, e.g. for neutrons, utilizing the corresponding type of radiation for testing.

This standard is intended to be applied to dosimetry systems that are capable of evaluating doses in the required quantity and unit (Sv) from readout signals in any quantity and unit. The only correction that may be applied to the evaluated dose (indicated value) is the one resulting from natural background radiation using extra dosemeters.

NOTE 5 The correction due to natural background can be made before or after the dose calculation.

This clause of Part 1 is applicable except as follows:

1.1.1     Equipment included in scope

Replace the existing text with the following:

This group safety publication is primarily intended to be used as a product safety standard for the products mentioned in the scope, but shall also be used by technical committees in the preparation of their publications for products similar to those mentioned in the scope of this standard, in accordance with the principles laid down in IEC Guide 104 and lSO/lEC Guide 51.

This part of IEC 61010 specifies safety requirements for hand-held and hand-manipulated current sensors described below.

These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured. They may be stand-alone current sensors or accessories to other equipment or parts of combined equipment (see Figure 101). These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. The existence of these current sensors and circuits in equipment requires additional protective means between the current sensor, the circuit and an operator.

NOTE 1 a combined equipment is an equipment that is electrically connected to a current sensor by means of a permanent connection which can be detached only by the use of a tool.

NOTE 2 Some current sensors are also known as current clamps, clamp multimeters and current probes.

Current sensors require hand-manipulation before and/or after a test or measurement, but do not necessarily need to be hand-held during the test or measurement. Current sensors used as fixed equipment are not within the scope of this part.

The following types of current sensors are covered:

Type A: a current sensor designed to be applied to or removed from uninsulated hazardous live conductors. Type A current sensors have defined hand-held or hand-manipulated parts providing protection against electric shock from the conductor being measured, and also have protection against short-circuits between wires and between busbars during clamping.

Type B: a current sensor which has protection against short-circuits between wires or busbars during clamping but without defined hand-held or hand-manipulated parts which provide protection against electric shock during clamping. Additional protective means are necessary to avoid electric shock from hazardous live conductors which cannot be de-energised during application or removal of the current sensor.

EXAMPLE 1 Flexible current sensors.

Type C: a current sensor without protection against short-circuits between wires or busbars during clamping. Type C current sensors are intended to be applied to or removed from uninsulated hazardous live conductors or from non-limited-energy circuit conductors only when they are de-energised.

EXAMPLE 2 Split-core transducers.

Type D: a current sensor designed to be applied to or removed from insulated conductors or from limited-energy circuit conductors.

EXAMPLE 3 Current probes for oscilloscopes and earth leakage current detectors.

All current sensors can also be used to insulated conductors. In this case, hazards are limited to acceptable levels by the insulation of the conductors.

Additional requirements for clamp multimeters are given in Annex EE.

The following Figure 101 shows graphical representations of typical current sensors for illustration purposes. Current sensors may look different depending on the design.
