3 Terms and definitions
Electromagnetic compatibility
The following terms and definitions apply to this standard. 3.1
Test and measurement techniques
Hand-held metal detector hand-held metal detector Radio frequency electromagnetic field radiation immunity test (IDT IEL) A hand-held metal detection device. The device can detect hidden metal objects exceeding a limited amount. In the technical standard, it is referred to as "detector".
GB 12899-—2003
Alarm Pusitive alarm
When detecting metal objects exceeding a limited amount, the detector uses the specified display and/or produces a sound to issue an alarm signal. 3. 3
Missing alarm
The detector does not alarm for the metal object that should be alarmed. 3.4
False alarm
The detector gives an alarm by mistake when the object that should be alarmed does not exist or has not been detected. 3.5
Measurement plane
Measurement plane
The probe is the sensor for the detector to detect the bottom. If a three-dimensional coordinate system is built at the center of the detection area of the probe (generally refers to the center of the probe's outer dimensions when there is no specification for the product), there will be a series of planes perpendicular to the measurement plane, which is called the measurement plane. Figure 1 is a side view, top view, coordinate system, measurement plane and outer shape schematic diagram of two different types of detectors. 3.6
Measurement base plane
A special measurement plane including the X-axis and the Y-axis, which divides the detection area of the detector into the upper and lower parts, is called the measurement base plane, see Figures 1 and 2.
Figure 1 Detector and test plane
Detection distance detection range
The maximum distance at which the detector can give an alarm for a given metal test object: It is equivalent to the distance from the test plane where the given metal test object is located to the detection base surface when the alarm can occur. 2
Detection mode test mode
CB 12899--2003
According to whether the detector approaches the test object along the Y axis or passes by the test object in the direction parallel to the Y axis, it is divided into approach mode and pass mode, see Figure 2.
Detection level detection lasers
This describes the detection capability of the detector for a given metal test object, which is generally divided into three levels according to the detection distance. The detection distance of level A is farther, the detection distance of level 3 is moderate, and the detection distance of level C is closer. 4 Technical requirements
