Sanitary tapware - Low pressure thermostatic mixing valves - General technical specification
Scope: This document specifies general construction, performance and material requirements for PN 10 thermostatic mixing valves (TMV) and includes test methods for the verification of mixed water temperature performance at the point of use below 45 °C. This does not exclude the selection of higher temperatures where available. When these devices are used to provide anti-scald protection for children, elderly and disabled persons the mixed water temperature shall be set at a suitable temperature (body temperature - 38 °C). In particular children are at risk to scalding at lower temperatures than adults. This does not obviate the need for supervision of young children.
It applies to valves intended for use on sanitary appliances in kitchens, washrooms (incl. all rooms with sanitary tapware, e.g. toilet and cloakrooms) and bathrooms operating under the conditions specified in Table 1.
This document allows TMVs to supply a single outlet or a small number of outlets in a “domestic” application (e.g. one valve, controlling a shower, bath, basin and/or, bidet), excluding valves specifically designed for supplying a large number of outlets (i.e. for institutional use).
The tests described are type tests (laboratory tests) and not quality control tests carried out during manufacture.

Facility Management - Part 3: Guidance on quality in Facility Management
Scope: This European Standard provides a guideline how to measure, achieve and improve quality in FM. It gives complementary guidelines to EN ISO 9000, EN ISO 9001 and EN 15221-2 within the framework of EN 15221-1. The standard provides a link into management methods and management theories. This European Standard is applicable to: - FM in public and private organizations; - client organization and service provider relationships; - full range of facility products or facility services; - both types of service providers in FM (internal and external); - all types of working environments (e.g. industrial, commercial, administration, military, healthcare etc.). This European Standard is applicable to business services (not consumer oriented). This European Standard does not: - replace the quality management systems of the client organization; - provide standard forms: - for performance and quality management systems (delivering a quality management system); - for defining requirements; - for a measurement tool; - for service level; - apply to the certification of the quality system of Facility Management (covered by EN ISO 9001).

Facility Management - Part 4: Taxonomy, Classification and Structures in Facility Management
Scope: FM covers and integrates a very broad scope of processes, products / services, activities and facilities. The approach of this standard is to consider the added value provided to the primary activities by adopting a product perspective as recognised by the primary processes or core business in the organisation. This standard therefore introduces the concept of standardised (classified) facility products. The scope of this standard is to provide taxonomy for FM which includes: - relevant interrelationships of elements and their structures in FM; - definitions of terms and contents to standardise facility products which provide a basis for cross border trade, data management, cost allocation and benchmarking; - a high level classification and hierarchical coding structure for the standardised facility products; - expanding the basic FM model given in EN 15221-1 by adding a time scale in the form of the quality cycle called PDCA (Plan, Do, Check, Act); - a linkage to existing cost and facilities structures; - alignment with the primary activities requirements. Additional benefits from this standard are: - Introducing a client rather than a specifically asset oriented view; - Harmonisation of different existing national structures (e.g. building cost codes) on an upper level relevant for the organisation and its primary activities.
