This part of ISO 18134 describes the method of determining the moisture in the analysis test sample by drying in an oven. It is intended to be used for general analysis samples in accordance with ISO 14780. The method described in this part of ISO 18134 is applicable to all solid biofuels. The moisture content of solid biofuels (as received) is always reported based on the total mass of the test sample (wet basis).
Since biofuels in small particle size are very hygroscopic, their moisture content will change with humidity in the atmosphere and therefore, the moisture of the test portion is determined simultaneously with determination of for example calorific value, carbon content, and nitrogen content.
NOTE The term moisture content when used with biomass materials can be misleading since untreated biomass frequently contains varying amounts of volatile compounds (extractives) which can evaporate when determining the moisture content by oven drying (see References[1] and[2].
This document defines the terminology to be used in the field of sustainability and greenhouse gas emission saving criteria for biomass for energy applications. This document specifically considers some relevant terms and definitions used in European Commission Directive 2018/EU/2001, the recast of the Renewable Energy Directive (RED II), and the European Commission Directive 2009/30/EC referred to as Fuel Quality Directive (FQD), or in other related European regulations.
This document defines procedures, criteria and indicators meeting the sustainability criteria of European Commission Directive 2018/EU/2001 (RED II), the recast of the Renewable Energy Directive, for agricultural biomass and forest biomass for energy applications, i.e. biofuels, bioliquids and biomass fuels. This document is applicable to production, cultivation and harvesting of biomass from agricultural land and forest land for biofuels, bioliquids and biomass fuel production.
This Standard establishes a method for determining the ethanol content in gasoline blends by gas chromatography (GC). This method is applied to gasoline samples with ethanol contents ranging from 1.02 to 52.3 %, in volume fraction.
