By the team at Zergo October 1, 2021
In accordance with the Safety Standard for the Use of Radiocommunication Equipment on Human Health, the criteria and measures in this Notification shall be applicable to the following three categories of radiocommunication equipment described in the Safety Standard:
Category 1 Radiocommunication equipment, of which the electromagnetic radiation component is, in normal use, positioned close to the user’s head, or less than 20 centimeters from the body of the user.
Category 2 Radiocommunication equipment, of which the electromagnetic radiation component is, in normal use, positioned at least 20 centimeters from the body of the user.
Category 3 Radiocommunication equipment in a fixed location and with a broad area of electromagnetic radiation.
Samples of Radiocommunication Equipment Categories
Category 1 – Samples:
– GSM900/GSM1800/GSM1900 mobile phones
– CDMA mobile phones
Category 2 – Samples:
– RFID device with over 100 m W transmitting output power
– Car radar device with over 100 m W transmitting output power
– Radiocommunication equipment used in some types of mobile/fixed activities
– On-site paging device
Category 3 – Samples:
– Base stations of all mobile phone systems
– Base stations or fixed stations for land mobile services
– Hub station of digital trunked radio system
– Hub station of amateur radio
Safety Criteria for Radiocommunication Equipment Category 1
Criteria of electromagnetic radiation assessment:
1) Radiocommunication equipment classified in Category 1 is subject to the assessment of specific absorption rate (SAR) as related to such equipment to ensure compliance with the Safety Standard.
2) Compliance declaration:
Besides having a compliance label shown on the equipment in compliance with the regulations regarding the assessment and certification of standards as announced by the Commission, entrepreneurs are duty-bound to make publicly known the conformity with the Safety Standard. The conformity with the Safety Standard shall be stated in the instruction manuals, or presented on the side of the packaging, or provided as additional documents packed together with such equipment. This aims at showing the users that the equipment carries the SAR in accordance with the Safety Standard.
The statement indicating the conformity with the Safety Standard shall be as follows:
“This radiocommunication equipment has the specific absorption rate (SAR) of … W/kg as related to the equipment, which is in compliance with the Safety Standard for the Use of Radiocommunication Equipment on Human Health announced by the National Telecommunications Commission.”
In the Thai language version:
“เครื่องวิทยุคมนาคมนี้มีอัตราการดูดกลืนพลังงานจำเพาะ (Specific Absorption Rate – SAR) อันเนื่องมาจากเครื่องวิทยุคมนาคมเท่ากับ … W/kg ซึ่งสอดคล้องตามมาตรฐานความปลอดภัยต่อสุขภาพของมนุษย์จากการใช้เครื่องงิทยุคมนาคมที่คณะกรรมการโทรคมนาคมแห่งชาติประกาศกำหนด”
Safety Criteria for Radiocommunication Equipment Category 2
Criteria of electromagnetic radiation assessment:
1) Radiocommunication equipment classified in Category 2 is subject to the assessment of electromagnetic field strength to ensure compliance with the Safety Standard.
2) Compliance declaration:
Besides having a compliance label shown on the equipment in compliance with the regulations regarding the assessment and certification of standards as announced by the Commission, entrepreneurs are duty-bound to make publicly known the conformity with the Safety Standard. The conformity with the Safety Standard shall be stated in the instruction manuals, or presented on the side of the packaging, or provided as additional documents packed together with such equipment. This aims at showing the users that the equipment has the electromagnetic field strength in accordance with the Safety Standard.
The statement indicating the conformity with the Safety Standard shall be as follows:
“This radiocommunication equipment has the electromagnetic field strength in compliance with the Safety Standard for the Use of Radiocommunication Equipment on Human Health announced by the National Telecommunications Commission.”
In the Thai language version:
“เครื่องวิทยุคมนาคมนี้มีระดับการแผ่คลื่นแม่เหล็กไฟฟ้าสอดคล้องตามมาตรฐานความปลอดภัยต่อสุขภาพของมนุษย์จากการใช้เครื่องวิทยุคมนาคมที่คณะกรรมการโทรคมนาคมแห่งชาติประกาศกำหนด”
Note:
Radiocommunication equipment in the frequency range of 9 kHz-300 GHz shall have the electromagnetic radiation in line with the Safety Standard as from the effective date of the Safety Standard.
