Protection and Management (Off-R oad Diesel Engi ne Emissions) 
Regulations 2012 and shall come in to operation on 1st July 2012. 
Definitions 
2.  In these Regulations, unless the context otherwise requires — 
“diesel engine” means an inte rnal combustion engine which 
operates by burning diesel; 
“examiner” means a testing facilit y accredited by the Singapore 
Accreditation Council or any of its Mutual Recognition 
Arrangement partners as bei ng able to perform exhaust 
emission tests for off-road diesel  engines in accordance with 
ISO 8178 test procedures; 
“motor vehicle” has the same meaning as in the Road Traffic 
Act (Cap. 276); 
“off-road diesel engine” mean s a diesel engine except —  3

owner of the off-road diesel engine; or 
 ( b) a person who has the use or  control of the off-road 
diesel engine under a credit agreement, hiring 
agreement, hire-purchas e agreement or leasing 
arrangement, 
but does not include any pers on provided to operate the

Import of off-road diesel engine 
5.—(1)  Subject to paragraph (2), no person shall on or after 
1st July 2012 import an off-road diesel engine except with the prior 
written approval of the Director-General. 
(2)  Paragraph (1) shall not appl y to any off-road diesel engine 
imported solely for re-export or tr anshipment to any other country. 
(3)  Any person who c ontravenes paragraph (1 ) shall be guilty of 
an offence. 
Application for import approval 
6.—(1)  An application for approva l to import an off-road diesel 
engine shall be submitted to the Di rector-General in such form and 
manner as he may require, together with — 
 ( a) a test report from the manufac turer of the o ff-road diesel 
engine or the manufacturer of the industrial plant in which the off-road diesel engine is  installed stating that the 
off-road diesel engine — 
 (i) conforms to any of the standards for exhaust 
emission specified in the Schedule; or 
 (ii) belongs to a model or  batch of off-road diesel 
engines that conform to any of the standards for exhaust emission specified in the Schedule; and 
 ( b) such other documents as the Director-General may require 
to satisfy the Director-Gener al that the o ff-road diesel 
engine conforms to any of the standards for exhaust emission specified in the Schedule.  5      
(2)  In considering an applica tion for approval to import an 
off-road diesel engine, the Dire ctor-General may require the 
applicant to submit to him a test report from an examiner stating 
that the off-road diesel engine was examined by the examiner on a 
date not earlier than 3 months before  the date of the application and 
was found to conform to any of th e standards for exhaust emission 
specified in the Schedule. 
PART III
