The parts shall be tested per the High-Temperature Operating Life (HTOL) requirements in JESD22-
A108 with the following special condition. The ambient test temperature and duration shall be per the
applicable operating temperature grade as follows:
Grade 0: 48 hours at 150°C or 24 hours at 175°C
Grade 1: 48 hours at 125°C or 24 hours at 150°C
Grade 2: 48 hours at 105°C or 24 hours at 125°C
Grade 3: 48 hours at 85°C or 24 hours at 105°C
Grade 4: 48 hours at 70°C or 24 hours at 90°C

Even the lowest Grade 4 also cannot meet. I dont know what to say about the quality of our civil service.

EDIT 1 May
This thread is targeted on the reply by LTA on 29 Apr, stating the reason for installing 3 piece unit in car rather than single piece unit on motorcycle is due to heat.


It is implied that the ambience temperature in the car parked outdoors will reach 52.4°C.

Whereas for motorcycle parked under trees (see video), the ambience temperature will reach 34.1°C

In the first place, if the agency's concern is life span used in automotive, why didnt they specify trialed and tested standards such as the AEC-Q100 which has been part of automotive industry for decades?

Moreover, are these ERP2.0 devices UNECE r10 certified for EMC as there are genuine concerns for radiation from these devices capable of transmitting and receiving?

The point is, for an authority that does registration and homologation, it is very hypocrite for them to turn a blind eye to products developed inhouse.

On 30 Apr, a certain motorcycle workshop measured the surface temperature of ERP2.0 parked outdoors to be a whooping 55.4°C.

So should we be concerned about the lifespan of the motorcycle unit or can we now install the motorcycle single piece unit in car since it will reach >50°C anyways?

1. The Land Transport Authority (LTA) awarded the ERP 2.0 project to the consortium formed by NCS Pte Ltd and MHI Engine System Asia Pte Ltd at a cost of S$556 million in 2016. As the project is still ongoing, details of the project costs will only be finalised upon completion.

kindly revise your statement to, "Unless you want the tender to cost $5bn of tax payer?"
