and Training (NIAIMT)

NIAIMT has two facilities under IMS:-

(1) Fixed Inspection Lanes, installed at NIAIMT’s Silchar Jaffirbond campus.

(2) Mobile Inspection Lanes, which can move to any place and can do

vehicle fitness test at the spot.

Fixed Inspection Lanes There are two lanes installed and commissioned at IMS lab. One lane is for Light Moving

Vehicle (LMV) and the other one is for Heavy Commercial Vehicle (HCV). Both lanes are fully

automated and computerized. The machines and equipments are installed and

commissioned by M/s Mustang Advanced Engineering (MAE), Ohio, USA which is one of

the world leaders in this sector.

Mobile Inspection Lanes There are two Mobile Inspection Lanes which can move to any place and can do Vehicle

Fitness test at the spot. Bothe the lanes are capable of testing LMV and HCV. Both lanes are

fully automated and computerized. The machines and equipments are installed and

commissioned by M/s Mustang Advanced Engineering (MAE), Ohio, USA which is one of

the world leaders in this sector.

Tests:- The below tests can be done for a particular vehicle at Fixed Inspection Lanes or Mobile

Inspection Lanes:-

1. Pollution Test (Opacity test for Diesel version and Gas analyzing

for petrol version)

2. Alignment Test (Side slip plates)

3. Headlight Test

4. Sound Test / Noise Test

5. Speedometer test

6. Brake test for multiple axles

7. Suspension Test (for LMV)

8. Joint Play test

9. Visual Check # Decelerometer (optional)

Report and Certificate:- After every test the data is automatically saved into the computers integrated and on

completion of all tests a computerized report is generated showing all test results

individually. The report cum certificate is Authorized and recognized by all.

Business Viability:- In India there is law to test all the commercial vehicles after particular intervals (1 year or

two year) and to get “Vehicle Fitness Certificate”. The fitness certificate is also important for

claiming Insurance. Here comes the demand for fitness testing. Only authorized centres can

issue fitness certificate to a vehicle. Generally one fitness testing centre covers a zone.

NIAIMT’s IMS is a state-of-the-art Authorized fitness testing centre.

1. Pollution / Emission test (Opacity/gas analysing):

Equipment: Capelec 4 Gas analyzer/opacimeter with RPM sensor.

Parameter for Petrol version: CO (% vol.), CO2 (% vol.), HC (ppm vol) ,

O2 (% vol.) and Lambda.

Parameter for Diesel version: Opacity ( /m), takes 10 accelerations.

Test time: 8-10 mins

2. Alignment Tester (Side slip plates):

Description: Alignment testers are also called side-slip plates because they measures sideways

movement of vehicle’s wheels when the vehicle is moving forward. The side-slip plates are fitted

with a sensor that measures the sideways drift of the vehicle in fit/mile or meter/km.

7. Suspension Tester:

Type: The BM40000 suspension tester is designed for axle load of up to 2000 kg. The

suspension tester is using the EUSAMA measuring principle for testing the suspension

system of the wheels. The unit consist of a one bed system with a vibration plate for left and

right wheel, which controlled by an electrical gear motor.

Results: The test results are as standard shown on an aluminium display with large point

meters for left and right wheel values and large 50 mm digital readout of imbalance

between left and right wheel.

Test Procedure: The test is performed by vibrating a plate vertical from app 25 down to 3 Hz

simulating all road conditions. During the test sequence the wheel weight is continuously

measured and the lowest saved for comparison with the static wheel weight.

The ratio between the lowest weight measured and the static weight is determined as the

EUSAMA value, which is also known as the Road Adhesion value. The value is presented in

percentage on the display and printout.

pivot points, suspension, hinge points and bearings all can be inspected while 4 hydraulic

rams induce 45° movements.

Features:

• Hand held pendant with flashlight and built in controls

• High friction wheel surface

• 4 hydraulic rams induce transverse and longitudinal movements
