ISO 24252:2021
Biogas systems — Non-household and non-gasification
This document applies for systems for biogas production by anaerobic digestion, biogas conditioning, biogas upgrading and biogas utilization from a safety, environmental, performance and functionality perspective, during the design, manufacturing, installation, construction, testing, commissioning, acceptance, operation, regular inspection and maintenance phases.
The following topics are excluded from this document:
— boilers, burners, furnaces and lighting in case these are not specifically applied for locally produced biogas;
— gas fuelled engines for vehicles and ships;
— the public gas grid;
— specifications to determine biomethane quality;
— transportation of compressed or liquefied biogas;
— transportation of biomass or digestate;
— assessment and determination whether biomass is sourced sustainably or not.
An informative explanation of the scope is included in Annex A.
