respectively, shall be registered up to six months after the respective
date of implementation of this rule.
(10) Every construction equipment vehicle shall be so manufactured that it
complies with the following standards of gaseous pollutants emitted by them when
tested on following duty cycle, namely:—
(a) for variable-speed engines, the 8-mode test cycle or the corresponding
ramped modal cycle and the transient cycle Non Road Transient Cycle
(NRTC);
(b) for constant-speed engines, the 5-mode test cycle or the corresponding
ramped modal cycle;
(c) emissions (g/kWh) shall be measured over applicable emission limit for
1
[Non-Road Steady Cycle (NRSC)] and Non-Road Transient Cycle (NRTC)
test cycle as per test applicability mentioned in Table 1 and Table 2 given
below and for NRTC test cycle, composite weighted emissions shall be
computed by weighing the cold start results 10 per cent. and the hot start
results 90 per cent. weighted composite results shall meet the limits given
in said- tables.
