Know allon Standards and Quality Marks

Certifying body

Approved standards originate from work carried out at different levels: global (ISO, IEC or ITU), European (CEN, CENELEC or ETSI) or national.

 

Standards

Approved standards are reference documents whose technical value is recognised and formalised by the public authorities, in particular to serve as a reference in a regulation, a public contract, a certification mark, etc. Approval as a standard is evidenced, depending on the level at which they were drawn up, by prefixes such as "NF EN", "DIN EN", "UNI EN", etc.

 

Quality marks

Quality or certification marks are awarded to products that comply with defined rules. They are based on a reference system designed by a certification body and published in the Official Journal.
Being certified requires being audited by an independent third party. The reference system of a quality mark is generally based on a standard (by modifying or supplementing it). Example: the NF mark, issued by AFNOR and CSTB, is based on
for taps, on NFEN standards, supplemented by "technical documents" supplied by the CSTB.

 

How are the standards transformed in each European country?

Taking the example of the European Certification Committee CEN, it is possible to see that all European countries will adapt this approved standard by name. The EN-XXXX standard will thus become the NFENXXXX standard in France. The certified external laboratories will grant the audited products a certification in relation to a standard or a quality mark.

MECHANICAL TEST BENCH STANDARDS

ISO 899-1 specifies a method for determining the tensile creep of plastics in the form of standard test specimens under specified conditions such as those of pretreatment, temperature and humidity. The method is suitable for use with rigid and semi-rigid non- reinforced, filled and fibre-reinforced plastics materials in the form of dumb-bell-shaped test specimens moulded directly or machined from sheets or moulded articles. The method is intended to provide data for engineering-design and research and development purposes. Data for engineering-design purposes requires the use of extensometers to measure the gauge length of the specimen. Data for research or quality-control purposes may use the change in distance between the grips (nominal extension).Tensile creep can vary significantly with differences in specimen preparation and dimensions and in the test environment. The thermal history of the test specimen can also have profound effects on its creep behaviour. Consequently, when precise comparative results are required, these factors are intended to be carefully controlled. If tensile-creep properties are used for engineering-design purposes, the plastics materials are intended to be tested over a broad range of stresses, times and environmental conditions.

This part of ISO 4210 specifies safety and performance requirements for the design, assembly, and testing of bicycles and sub-assemblies, and lays down guidelines for manufacturer’s instructions on the use and care of such bicycles.


This part of ISO 4210 applies to young adult bicycles with maximum saddle height of 635 mm or more and less than 750 mm, city and trekking bicycles, mountain bicycles, and racing bicycles that have a maximum saddle height of 635 mm or more including folding bicycles.

This European Standard specifies the method to be used to determine the resistance to repeated opening and closing of windows and pedestrian doorsets when subjected to repeated opening and closing. It applies to all construction materials and operating systems for any window or pedestrian doorset, including gaskets and building hardware, in normal operating conditions.  The parts concerned in the testing are the frame, the opening component (including any additional moving components e.g. an inactive sash/leaf) and all essential and directly involved building hardware, including operating devices, for example, the handle.

This standard specifies the functional requirements and test methods for external organic coatings based on tapes or shrinkable materials to be used for corrosion protection of buried and immersed steel pipelines in conjunction with cathodic protection. It classifies coatings by increasing mechanical resistance and operating temperatures. Coatings for special installation conditions are also considered. A comprehensive classification of coatings in relation to functional requirements is defined.

The purpose of this part of this European Standard is to describe the impact bending test on Charpy specimens (V-notched and U-notched) of metallic materials. For some particular metallic materials and for some particular applications, the impact bending test may be subject to specific standards or conditions.

The purpose of this European standard is to control the impact bending test machines (impact pendulums) used for the impact bending test on Charpy test specimens in accordance with EN 10045-1.

It describes two methods: - the direct method allowing to verify statically and separately the geometrical and physical characteristics of the different parts of the impact pendulum, - the indirect method: a global method of impact pendulum checking using Charpy-V reference specimens such as defined in 6.2.

The direct method is to be used, on the one hand, during the installation or repair of the machine and, on the other hand, in the case where the indirect method gives an incorrect result, in order to investigate the cause. This standard also applies to reference impact pendulums whose geometrical characteristics are defined in Annex B. This standard may be applied in a similar way to impact pendulums of different capacities or of different design. Impact pendulums checked in accordance with this standard and found to be satisfactory shall be considered as valid for testing with test specimens of different notch types. The equipment used for the direct method must have certified traceability in relation to the International System of Units. Annex A defines, for information purposes, a method of direct verification of certain geometric characteristics using a template. Annex B defines, for information purposes, a guide for the preparation and characterization of reference specimens.
