This document specifies a general test procedure for quantification of the spontaneous heat generation from solid biofuel pellets using isothermal calorimetry.

This document further:

— specifies a screening test procedure for wood pellets using an instrument temperature of 60 °C,

— establishes procedures for sampling and sample handling of solid biofuel pellets prior to the analysis of spontaneous heat generation, and

— gives guidance on the applicability and use of isothermal calorimetry for calculation of the net reaction rate of the heat producing reactions of solid biofuel pellets.

The test procedure given in this document quantifies the thermal power (heat flow) of the sample during the test, it does not identify the source of self-heating in the test portion analysed.

Data on spontaneous heat generation determined using this document is only associated with the specific quality and age of the sample material. The results are product specific.

This document is applicable to solid biofuel pellets only.

The information derived using this document is for use in quality control and in hazard and risk assessments related to the procedures given in ISO/DIS 20024:2019.

This document specifies methods for obtaining samples of lubricating grease from production lots or shipment.

The methods and the ways of preparing samples differ depending on whether the sampling is performed on manufactured lots in a blending plant or on the delivery site.

This document gives general guidelines for the design, material selection, qualification, certification, and testing details of hose assemblies for Liquefied Natural Gas (LNG) marine transfer applications.

The transfer hose assemblies are part of transfer systems (it means that they may be fitted with ERS, QCDC, handling systems, hydraulic and electric components etc.) To avoid unnecessary repetition, cross-references to EN ISO 16904 and EN 1474-3 are made for all compatible items, and for references, definitions and abbreviations. Where additional references, definitions and abbreviations are required specifically for LNG hoses, they are listed in this European Standard.
