Scope: This section applies to any wireless communication device that can emit electromagnetic fields (EMF), is used close to the human body in the manner described by the manufacturer, and the transmitting part is no more than 200mm away from the human body, whether it is handheld or placed in front of the face, or on the body Wearable, integrated with other emitting or non-emitting devices or accessories (such as belt clips, cameras or Bluetooth), or implanted in clothing. Equipment used with the transmitting part close to the ear can be tested according to the requirements of YD/T 1644.1 (IEC 62209-1:2005). This section is applicable to radio frequency exposure in the operating frequency range of 30MHz to 6GHz, and can also be used to measure simultaneous exposure from multiple radio emission sources close to the human body. This section provides definitions and evaluation procedures for the following device types: body-worn, body-supported, desktop, face-held, handheld, lap-worn, body-worn, multi-band, walkie-talkie, Clothing integrated. Device types include, but are not limited to, mobile phones, cordless phones, auxiliary broadcast equipment, and radio transmitters within personal computers. This section presents a repeatable and conservative measurement method for assessing compliance of wireless devices with SAR limits. Because existing research shows that human models that do not include parts representing human hands can give a conservative scenario for SAR evaluation within the human torso and head, if the device is expected to be used close to the head or torso or using a torso support, the human model should be used during evaluation It does not include parts representing human hands [73], [80]. This section does not apply to exposure assessments of emitting or non-emitting medical implantable devices. This section does not apply to the exposure assessment of equipment that is more than 200mm away from the human body. This section quotes some applicable complete chapters in YD/T 1644.1 (IEC 62209-1:2005) and gives descriptions of different parts.
