Efficiency of the Non-Methane Cutter (NMC, For NG Fuelled Gas Engines Only)

The re-indexing of the blade cutter depth is achieved automatically after each rotation

The cutter oxidises all hydrocarbons except CH4 to CO2 and H2O, so that by passing the sample through the NMC only CH4 is detected by the FID.

- Using blade cutters, up to 90% of the pipe wall is cut.

The cutter shall be characterised at or above 600 K (327 °C) prior to test work with respect to its catalytic effect on CH4 and C2H6 at H2O values representative of exhaust stream conditions.

If bag sampling is used, a flow diverter system shall be installed at SL (see section 1.2, Figure 8) with which the flow can be alternatively passed through or around the cutter according to the upper part of Figure 10.

Italy has noted that many fatal accidents have occurred in its territory following the use of silage cutters manufactured in accordance with standard EN 703.

The references of standard EN 703 "Agricultural machinery - Silage cutters - Safety" are withdrawn from publication in the Official Journal of the European Communities.

- Before the external cutting tools break through the interior of the pipe, the blade cutters are replaced by cutting wheels, which separate the pipe from the old SG without introducing debris into the pipe.

Commission Decision of 25 October 2000 on withdrawing the references of standard EN 703 "Agricultural machinery - Silage cutters - Safety" from the list of references of standards in the framework of implementing Directive 98/37/EC

The references of harmonised standard EN 703:1995 "Agricultural Machinery - Silage cutters - Safety" were published in the Official Journal of the European Communities C 229 of 8 August 1996 in the framework of implementing Directive 98/37/EC, as amended.
