This document specifies the standard test method to assess the performance of dust collectors utilizing integrated fans (compact type dust collector), at the time of manufacture, after being used for a certain period. This document adopts the black box concept that the dust collector to be tested is operated with the specification determined by the manufacturer except test dust condition and the pulse interval during ageing. This document is applicable to small dust collectors utilizing cartridge filters including molded filters or bag filters with pulse cleaning equipment as filtration media for dry dust collection. Mist and fumes collectors are excluded from this test. The performance obtained from this test does not guarantee the performance of the system. This document is not intended to offer the superiority or inferiority of performance between dust collectors, but specifies a standard test method that provides users with performance under simulated conditions of use for a certain duration.

This document specifies methods for the testing and rating of dampers and valves used in air distribution systems with pressure differences up to 2 000 Pa.
The tests incorporated in this document will address:
- leakage past a closed damper or valve (for classification, see Annex C);
- casing leakage (for classification, see Annex C);
- flow rate/pressure requirement characteristics;
- torque: (see Annex A);
- thermal transmittance: (see Annex B).
The tests specified above are applicable to the following:
- measurement of leakage past a closed damper or valve;
- measurement of casing leakage;
- determination of flow rate and pressure requirements;
- measurement of torque characteristics (see Annex A);
- measurement of thermal transfer characteristics to determine insulation properties (see Annex B).
This document does not apply to the acoustic testing of dampers and valves.
NOTE Certain aspects of the dynamic performance of dampers and/or valves are dependent upon the air distribution system to which they are connected and are, therefore, difficult to measure in isolation. Such considerations have led to the omission of these aspects of the dynamic performance measurements from this document. Also, in common with other air distribution components, the results from tests carried out in accordance with this document might not be directly applicable if the damper or valve is situated in an area of non-uniform flow.

This document specifies procedures and conditions to enable the heat flux in electrical surface heating systems to be determined relative to the medium differential temperature for systems. The determination of thermal performance electrical surface heating systems and their conformity to this document is carried out by calculation in accordance with design documents and a model. This enables a uniform assessment and calculation surface heating systems.
The surface temperature and the temperature uniformity of the heated surface, nominal heat flux density between electrical heated layer and space are given as the result.
The ISO 11855 series is applicable to water based embedded surface heating and cooling systems in residential, commercial and industrial buildings[1]. The methods apply to systems integrated into the wall, floor or ceiling construction without any open-air gaps. It does not apply to ceiling mounted panel systems with open air gaps which are not integrated into the building structure.
The ISO 11855 series also applies, as appropriate, to the use of fluids other than water as a heating or cooling medium. The ISO 11855 series is not applicable for testing of systems. The methods do not apply to heated or chilled ceiling panels or beams.
[1] ISO 11855-7 can also be used for electrical heated embedded systems.

This standard applies to the natural ventilation and fan-assisted ventilation of residential buildings,
dwellings and similarly used units which are predominantly used for living purposes, including halls of
residence, retirement homes and nursing homes, and similar institutions during the heating period and throughout the entire year in basements (see Annex F) in residential buildings.
The ventilation concept specified in Clause 4 and Clause 5 applies to new buildings and to existing buildings in which modifications are made relevant to the ventilation regime. Where there is no moisture-protection ventilation, or if additional requirements (e. g. noise protection, hygiene, air quality, etc.) are to be taken into consideration, then suitable ventilation measures are suggested in Clauses 7 to 9.
In Clauses 6 to 9 this standard specifies requirements for natural ventilation systems (cross ventilation, shaft ventilation), fan-assisted ventilation systems, and combinations thereof, taking into consideration the maintenance of the necessary indoor air quality while ensuring moisture protection.
Ensuring ventilation for the purposes of moisture protection by manually opening windows is not covered by this standard. Manual opening of windows is taken into consideration for ventilation levels that are not explicitly designed for.
This standard specifies requirements on the planning, design and commissioning, and the operation and maintenance of the required ventilation components and/or units for natural ventilation systems and fan-assisted ventilation systems with user-independent moisture protection in each case, making due allowance for aspects of construction engineering physics, ventilation, hygiene and energy utilization.
The design recommendations of this standard apply for dwellings with low emissions of harmful substances.Unduly high emissions from the building and in the building environment may require additional measures.
This standard does not apply to active cooling1 air treatment methods nor to active humidification and dehumidification.
As regards the ventilation of windowless rooms, the Bauaufsichtliche Richtlinie über die Lüftung fensterloser Küchen, Bäder und Toilettenräume (Code of practice on ventilation of windowless kitchens, bathrooms and toilet rooms) and DIN 18017-3 apply to the ventilation of windowless kitchens, bathrooms and WCs in dwellings
