This document specifies a chamber method with three options of test chambers for the determination of the formaldehyde emission from wood-based panels in terms of the steady-state concentration in a climate chamber under defined conditions, which relate to typical conditions in real-life. This chamber method can also be applied to the estimation of formaldehyde concentrations under various conditions in practice, by the use of mathematical models. This document can also be used for the testing of formaldehyde emissions of products other than wood-based panels.

 

The tests specified in ISO 22899-1 and ISO 22899-3 are designed to give an indication of how passive fire protection materials and systems will perform in a jet fire. This part of ISO 22899 provides: — guidance on the selection of applicable method of test; — guidance on the combination of results from hydrocarbon tests and resistance to jet fire tests. ISO 22899-1 and ISO 22899-3 tests report the thickness of fire protection material or system (sometimes referred to as passive fire protection; PFP) required to resist the application of a ‘jet fire’.

 

This document specifies procedures for assessment and verification of constancy of performance (AVCP). This document is applicable to roomheaters, inset appliances and cookers which can be fired batchwise in fuel baskets for wood pellets (freestanding manually fuelled intermittent burning appliances). This document is applicable to appliances with fully integrated baskets for wood pellets which are integral component of the appliance. If the appliance is to be fired with wood logs or compressed untreated wood (wood briquettes), the configuration of the combustion chamber can be changed according to the instructions. Different fuels cannot be operated at the same time and they can be tested separately according the relevant part of EN 16510-2-x. The intended use of the appliances is space heating in residential buildings and can be cooking (when tested accordingly). These appliances can be supplied either as an assembled appliance or as a predesigned unit consisting of prefabricated components designed to be built on site in accordance with the specified assembly instructions. They only operate with the firedoors closed. This document is not applicable to: - mechanically fed appliances; - appliances with fan assisted combustion air; - appliances with boiler.
