IEC 62706-2019 pdf free.Radiation protection instrumentation – Recommended climatic, electromagnetic and mechanical performance requirements and methods of tests.
The instrument-specific standard should indicate whether an influence quantity usually acts astype S or F.The radiation level chosen for each test should be based on the type of influencequantity as described in 5.3.2.2 and 5.3.2.3.In case the type of influence quantity is unknown(s or F), then tests should be performed according to both types (S and F), i.e. according to5.3.2.2 and 5.3.2.3.
5.3.2.2Tests for influence quantities of type s
These tests should be performed at a dose (rate) that is low enough to ensure that an effectfrom the test is measurable (e.g.，10 times the lower limit of the effective range ofmeasurement but not zero in order to be able to detect a reduction in the indication).
5.3.2.3Tests for influence quantities of type F
For these tests，the dose (rate) chosen should be high enough to ensure that statisticalfluctuations are small enough to demonstrate whether the requirement is met (e.g., at least 10times above the lower limit of the measuring range).
5.3.3 Climatic requirements
Climatic requirements apply to different types of radiation detection instruments based ontheir design and expected use.The climatic requirements that apply to a specific instrumenttype are addressed by that instrument-specific standard.As a minimum, ambient temperatureand relative humidity tests should be required for all types of radiation detection instruments.Other climatic conditions should be established as appropriate for the expected conditions ofuse.
The following example text may be used in an individual standard as reference to thisdocument: “The instrument shall undergo the tests specified in IEC 62706,Clause 7,concerning the climatic requirements for [insert instrument designation here, i.e., body-worn,handheld, installed, etc.] instrumentation.’It is advisable not to insert the year of publicationin the normative references citing lEC 62706. Thus, the latest edition of this document will beconsidered.
5.3.4 Mechanical requirements
Mechanical requirements apply to different types of radiation detection instruments based on:their design and expected use. The mechanical requirements that apply to a specificinstrument type are addressed by that specific standard.As a minimum,vibration, mechanicalshock,and impact should be required for all types of radiation detection instruments.
The following example text may be used in an individual standard as reference to thisdocument: “The instrument shall undergo the tests specified in lEC 62706,Clause 8,concerning the mechanical requirements for [insert instrument designation here, i.e.，body-worn，handheld，installed,etc.] instrumentation.” lt is advisable not to insert the year ofpublication in the normative references citing lEC 62706. Thus，the latest edition of thisdocument will be considered.IEC 62706 pdf download.
