M/475 - Biomethane

This document explains an approach for assessment of limit values for contaminants that may be found
in biomethane. Limit values are generally required as an adjunct to a biomethane specification (such as
parts 1 and 2 of EN 16723, or an equivalent National specification) or as part of a Network Entry
Agreement for injection of biomethane into gas networks.
The methodology employed will permit derivation of limit values based solely on consideration of
potential for impact on human health and does not consider other impacts, such as integrity and
operation of plant and pipelines used to convey biomethane or appliances involved in its combustion or
other regulations like CLP regulation. Where consideration of such impacts would result in proposing
lower limit values than those based on health impacts, then the lowest limit values should generally be
proposed.

This standard specifies the requirements and test methods for natural gas, biomethane and blends of both at the point of use as automotive fuels.
This standard applies to the previously mentioned fuels irrespective of the storage state (compressed or liquefied).
NOTE: to check compliance with some requirements set by the standard, LNG or liquefied biomethane has to be re-gasified prior to testing.

This European Standard specifies the requirements and test methods for natural gas (group L and H, as in EN 437), biomethane and blends of both at the point of use as automotive fuels.

This document specifies the requirements and test methods for the construction, safety, and marking of decorative fuel effect gas appliances not exceeding a nominal heat input of 20 kW (based on the net calorific value), thereafter referred to as appliances.
This document is applicable to appliances that are designed to simulate a solid fuel fire and incorporate a natural draught burner with or without an ignition burner. The appliances are for decorative purposes only and are not heating appliances.
This document is applicable to type BAS, as described in 4.2, decorative fuel effect gas appliances that are designed to be installed within a non-combustible builder's opening or a non-combustible fireplace recess.
This document includes additional requirements for Type BBS appliances which are specified in Annex F.
In addition, this document is applicable to decorative fuel-effect gas appliances that are designed to be installed under a non-combustible canopy which may be independent or integral with a flue box, for which additional requirements are specified in Annex A.
This document is not applicable to:
-   catalytic combustion appliances;
-   appliances in which the supply of combustion air and/or the evacuation of products of combustion is achieved by mechanical means.
This document is only applicable to appliances which are intended to be type tested.
Matters related to quality assurance systems, tests during production and to certificates of conformity of auxiliary devices are not dealt with by this document.
Requirements concerning the rational use of energy have not been included in this document because the appliances are for decorative purposes.
