General specifications for walk-through metal detector
1 Scope
This Standard specifies technical requirements, test methods, inspection rules,
identifications, marks, labels and packaging, accompanying technical
documents of walk-through metal detector.
This Standard is applicable to the walk-through metal detector that detects
metal weapons and metal prohibited goods. The walk-through metal detectors
for other usages may refer to this Standard.

3.9 detector position
The position selected in the detector plane through which 12 test objects shall
pass. These positions are based on the average height setting of an adult man.
They are respectively located on ankles, legs, crotch, hands, chest, double
armpits, head and head top. In the coordinate system, they are the points
defined by the x and z values.
3.10 auto-test system
An automatic testing equipment that simulates the process of the human body
carrying the test object through the detector plane, the test object can be
clamped to perform linear translation movement in the X, Y, Z three-axis
coordinate system.
3.11 standard tester
A human being with a height of 1.55m~1.85m, a weight of 50kg~90kg, who
does not carry any metal or conductive objects, magnetic materials, or any
metal inserts in the body.
4 Classification
According to the detection class, the walk-through metal detector (hereinafter
referred to as "metal detector") is divided into class I, class II, class III and mixed
class:
- Class I: the metal detector that can detect half-piece razor blades;
- Class II: the metal detector that can detect screwdriver, non-magnetic
stainless-steel dagger, and has no alarm for metal pen;
- Class III: the metal detector that can detect magnetic stainless-steel
daggers and aluminum knives, while not alarming stainless-steel keys;
- Mixed type: the metal detector that through parameter adjustment, the
detection capability can reach two or three of Class I, Class II, and Class
III.
5 Technical requirements
5.1 Appearance
The appearance of metal detector shall meet the following technical
b) The grounding is stable and shall be able to resist normal impact without
sliding imbalance;
c) For the metal detector with foot pedal at the bottom, the gap between the
foot pedal and the main structure of the metal detector shall be less than
or equal to 10mm; there shall be no obvious collapse, twisting, warping or
displacement when the foot pedal carries 120kg.
5.2.4 Enclosure protection level
Indoor working type: in accordance with relevant technical requirements of IP41
in GB/T 4208-2017.
Outdoor working type (with shield): in accordance with relevant technical
requirements of IP53 in GB/T 4208-2017.
5.3 Operational control
5.3.1 Operational authorization
Devices and parameters that affect detection performance shall be protected to
prevent unauthorized changes.
5.3.2 Buttons and control devices
Buttons and control devices shall be flexible, clear in touch, and reliable in
function. For the metal detector equipped with remote control, the remote-
control distance shall be greater than or equal to 2m.
5.3.3 Parameter storage
The metal detector shall have the ability to store the set parameters. The
parameters shall not be changed when power is turned on again after power
off.
5.3.4 Remote control
If centralized control via remote computer or network is allowed, corresponding
control procedures shall be provided. And it shall have the function of remote
parameter adjustment, remote diagnosis and alarm related data storage. When
the remote control is interrupted for any reason, the metal detector shall be able
to automatically restore local control.
5.4 Power adaptability
The power adaptability of the metal detector shall meet the following
requirements:
a) The metal detector that uses AC power supply shall be able to work
The metal detector alarm sound shall meet the following requirements:
a) It is different from non-alarm sound, and the alarm indicator does not
produce any sound when it is non-alarm;
b) The tone can be adjusted so that the alarms of two adjacent metal
detectors can be clearly distinguished;
c) It can be adjusted from mute to maximum sound intensity. At 0.8m away
from the metal detector, the maximum sound intensity is greater than or
equal to 85dB.
5.8.2.2 Alarm display
The metal detector alarm display shall meet the following requirements:
a) The color is red, and it is different from the non-alarm display;
b) If there is a partition detection function, the partition positioning can be
seen at a glance and the position shall be accurate;
c) In 6000lx bright environment and 25lx dim environment, it can be clearly
