91.140 - Installations in buildings

This document specifies the requirements for solid wall pipes with smooth internal and external surfaces, extruded from the same formulation throughout the wall, fittings and the system of unplasticized poly(vinyl chloride) (PVC-U) piping systems intended for soil and waste discharge applications (low and high temperature):
-   inside buildings (application area code "B");
-   for both inside buildings and buried in ground within the building structure (application area code "BD").

The particular requirements of this part apply to fixed equipment in conducting locations where movement of persons is restricted by the location, and to supplies for portable equipment for use in such locations. A conducting location with restricted movement is comprised mainly of metallic or other conductive surrounding parts, within which it is likely that a person will come in contact through a substantial portion of his body with the metallic or other conductive surrounding parts and where ...view more

This document specifies methods for measuring the aerodynamic and acoustic characteristics of cowls and roof outlets used in both natural and mechanical ventilation. Only those cowls and roof outlets fitted onto ducts which project above the roof surface are covered by the present standard.
Regarding the assisted cowls, only the fan assisted cowls are covered by the present standard, other types (such as injection assisted cowls) being too recent to be adequately considered for the time being.

1.1   This European Standard deals with safety requirements for construction, manufacturing, installation, maintenance and dismantling of electrically operated stairlifts (chair, standing platform and wheelchair platform) affixed to a building structure, moving in an inclined plane and intended for use by persons with impaired mobility:
-   travelling over a stair or an accessible inclined surface;
-   intended for use by one person;
-   whose carriage is directly retained and guided by a guide rail ...view more

This document is a collection of interpretations related to the EN 115 series. This document collects interpretations to EN 115 1:2008+A1:2010 and EN 115-1:2017. Interpretations to other standards of the EN 115 series will be added when they are available.
Interpretations aim to improve the understanding of the clause(s) they are referring to and by that facilitating common understanding between manufacturers, lift installers, notified bodies, inspection bodies and national authorities.

This document specifies a test method for determining the leaktightness of elastomeric sealing ring
type joints for buried thermoplastics non-pressure piping systems.
Unless otherwise specified in the referring standard, the tests are carried out at the following basic test
pressures:
— p1: internal negative air pressure (partial vacuum);
— p2: a low internal hydrostatic pressure;
— p3: a higher internal hydrostatic pressure.
It also describes the following four test conditions under whic...view more

This clause of part 1 is applicable except as follows.
Addition:
This standard applies to open outlet, single point of use, electric instantaneous water heaters intended for household or similar use, for showering purposes without downstream mixing.
This standard only specifies tests for the assessment of energy efficiency.
This standard does not apply to electrical instantaneous water heaters covered by other parts of this series of standards.

This European Standard applies to electric instantaneous water heaters for domestic hot water heating for household and similar applications, which show both of the following characteristics:
–   fulfilling at least one load pattern from Annex A;
–   heating up to temperatures below the boiling temperature.
This European Standard specifies terms, definitions and measurement methods for the assessment of energy efficiency.
This European Standard does not take into account requirements regarding t...view more
