Title:	Environmental Requirements from S4.01A

Document for:	

This is a corresponding section in S4.01A, discussed in TSG-RAN WG4. 
(It is only copied for the convenience of discussion in T2. No change or proposal is included.)

Annex C (normative): Environmental conditions
C.1	General
This normative annex specifies the environmental requirements of the UE. Within these limits the requirements of this specifications shall be fulfilled.
C.2	Environmental requirements 
The requirements in this clause apply to all types of UE(s)
C.2.1	Temperature
The UE shall fulfil all the requirements in the full temperature range of:

[+15]C – [+35] C	for normal conditions (with relative humidity of 25 % to 75 %);	
[-10]C ‑ [+55]C	for small UE units extreme conditions (see IEC publications 68‑2‑1 and 68‑2‑2)	
[-20]C ‑ [+55]C	For other units extreme conditions (see IEC publications 68‑2‑1 and 68‑2‑2).
	
Outside this temperature range the UE, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the UE exceed the transmitted levels as defined in S4.01A for extreme operation.
C.2.2	Voltage
The UE shall fulfil all the requirements in the full voltage range, i.e. the voltage range between the extreme voltages.

The manufacturer shall declare the lower and higher extreme voltages and the approximate shutdown voltage. For the equipment that can be operated from one or more of the power sources listed below, the lower extreme voltage shall not be higher, and the higher extreme voltage shall not be lower than that specified below.

Power source	Lower extreme
voltage	Higher extreme
voltage	Normal conditions
Voltage	
AC mains	0,9 * nominal	1,1 * nominal	Nominal
	
Regulated lead acid battery	0,9 * nominal	1,3 * nominal	1,1 * nominal
	
Non regulated batteries:
-	Leclanché/lithium
-	Mercury/nickel cadmium	
0,85 * nominal
0,90 * nominal
	
Nominal

Nominal	
Outside this voltage range the UE if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the UE exceed the transmitted levels as defined in S4.01A for extreme operation. In particular, the UE shall inhibit all RF transmissions when the power supply voltage is below the manufacturer declared shutdown voltage.
C.2.3	Vibration
The UE shall fulfil all the requirements when vibrated at the following frequency/amplitudes:

Frequency	ASD (Acceleration Spectral Density) random vibration	
5 Hz to 20 Hz	0,96 m2/s3	
20 Hz to 500 Hz	0,96 m2/s3 at 20 Hz, thereafter ‑3 dB/Octave	
Outside the specified frequency range the UE, if powered on, shall not make ineffective use of the radio frequency spectrum. In no case shall the UE exceed the transmitted levels as defined in S4.01A for extreme operation
