Information technology — Data centre facilities and infrastructures — Part 3: Power distribution
This document addresses power supplies to, and power distribution within, data centres based upon the criteria and classifications for “availability”, “physical security” and “energy efficiency enablement” within ISO/IEC 22237‑1.
This document specifies requirements and recommendations for the following:
a) power supplies to data centres;
b) power distribution systems to all equipment within data…
Information technology — Data centre facilities and infrastructures — Part 1: General concepts
This document:
a) describes the general principles for data centres upon which the requirements of the ISO/IEC22237 series are based;
b) defines the common aspects of data centres including terminology, parameters and reference models (functional elements and their accommodation) addressing both the size and complexity of their intended purpose;
c) describes general aspects of the facilities and…
Health informatics — Audit trails for electronic health records
This document specifies a common framework for audit trails for electronic health records (EHR), in terms of audit trigger events and audit data, to keep the complete set of personal health information auditable across information systems and domains.
It is applicable to systems processing personal health information that create a secure audit record each time a user reads, creates, updates, or…
Rubber- or plastics-coated fabrics — Determination of tear resistance — Part 2: Ballistic pendulum m...
This document specifies a method for the determination of tear resistance based on the action of an active force applied to a notched test piece.
The test can be carried out on:
test pieces that have been conditioned in a standard atmosphere; or
test pieces that have undergone pre-treatment, e.g. water immersion.
The results obtained by this method cannot be compared with those obtained by…
