Title:	Proposal on Environmental and Reliability Requirements
                 and Electrical Safety Requirements

Document for:	

This document includes our basic idea and proposal on the “Environmental and Reliability Requirements” and “Electrical Safety Requirements”.

1.	Environmental and Reliability Requirements
(1)	ARIB inputted related sections from ARIB document Vol.4 at the last meeting. 
The basic idea of ARIB is that we do not need to change these requirements from the conventional system.
(2)	In TSG-RAN WG4, there was a discussion on the environmental requirements 
because these requirements are closely related to radio performance. 
RAN WG4 made a draft of this specification in S4.01A Annex C (the document number of the latest draft is R4-99087). In that document, they specified temperature, voltage and vibration conditions, based on GSM05.05.
(3)	<Our Proposal> 
- Temperature, voltage and vibration requirements shall be treated in RAN WG4. 
- Reliability requirements should be deleted.
- Other items, such as humidity and shock stability, can be deleted after discussed further.

2.	Electrical Safety Requirements
(1)	     ARIB inputted related sections from ARIB document Vol.4 at the last meeting. 
ARIB proposes that the “electrical safety” and the “safety of radio” requirements shall be based on a selected parts of IEC950 and IEC215 which are international standard. 
The actual content is for further study.
