IS 18724 : 2024 Solid Biofuels - Fuel Specifications and Classes - Pellets from Agro and Herbaceous Residues

ICS 27.190; 75.160.40

PCD 07

1 SCOPE

This standard prescribes the fuel quality classes and specifications of pellets produced from agro and other herbaceous residues.

NOTES

1 Blends and mixtures include blends and mixtures from the main origin-based solid biofuel groups like woody biomass, herbaceous biomass, fruit biomass and aquatic biomass. Blends are intentionally mixed biofuels, whereas mixtures are unintentionally mixed biofuels. The origin of the blend and mixture is to be described using ISO 17225-1 of Table 1. If solid biofuel blend or mixture contains chemically treated material, it shall be stated.

2 Thermally treated biomass pellets (for example, torrefied pellets) are not included in the scope of this standard.
