Technologies de l'information - Indicateurs de performance clés des centres de données - Partie...
Le présent document spécifie l'indicateur de réutilisation de l'énergie (ERF) en tant que KPI permettant de quantifier la réutilisation de l'énergie consommée dans un centre de données. L'indicateur ERF est défini comme étant le rapport de l'énergie réutilisée sur la somme de toutes les énergies consommées dans un centre de données. L'indicateur ERF permet de rendre…
Internal combustion engines — Piston rings — Part 1: Rectangular rings made of cast iron
This document specifies the essential dimensional features of rectangular rings made of cast iron, Types R, B, BA and M, having diameters up to and including 200 mm, used in reciprocating internal combustion piston engines. It is also applicable to piston rings of compressors working under similar conditions.
Elastomeric seismic-protection isolators — Part 5: Sliding seismic-protection isolators for building...
This document specifies minimum requirements and test methods for flat sliding seismic-protection isolators used for buildings and the materials used in the manufacture of such isolators.
It is applicable to flat sliding seismic-protection isolators used to provide buildings with protection from earthquake damage. The sliders are each mounted on elastomeric bearings to provide vertical compliance…
Textiles — Water resistance — Rain tests: exposure to a horizontal water spray
This document specifies a test for measuring the resistance of fabrics to the penetration of water by impact. It can be used to predict the probable rain penetration resistance of textile fabrics.
This document is applicable to any textile fabric, whether or not it has been given a water-resistant or water-repellent finish. It is especially suitable for measuring apparel fabrics. Testing at…
Passenger car tyres — Verifying tyre capabilities — Laboratory test methods
This document specifies test methods for verifying the capabilities of tyres for passenger cars. Of the test methods presented, it is possible that only some will be required depending on the construction of the tyre (diagonal, bias-belted, radial or T-type construction) to be tested. The tests are carried out in a laboratory under controlled conditions.
This document includes endurance tests, a…
Identification cards — Integrated circuit cards — Part 8: Commands and mechanisms for security opera...
This document specifies interindustry commands which can be used for security operations. This document also provides informative directives on how to construct security mechanisms with commands defined in ISO/IEC 7816‑4.
The choice and conditions of use of cryptographic mechanism in security operations can affect card exportability. The evaluation of the suitability of algorithms and protocols…
