Medical electrical equipment — Part 2-31: Particular requirements for the basic safety and essential...
IEC 60601-2-31:2020 applies to the BASIC SAFETY and ESSENTIAL PERFORMANCE of EXTERNAL PACEMAKERS powered by an INTERNAL ELECTRICAL POWER SOURCE, hereafter referred to as ME EQUIPMENT. This document applies to PATIENT CABLES as defined in 201.3.209, but does not apply to LEADS as defined in 201.3.206. HAZARDS inherent in the intended physiological function of ME EQUIPMENT within the scope of this…
Metallic materials — Instrumented indentation test for hardness and materials parameters — Part 1: T...
ISO 14577-1:2015 specifies the method of instrumented indentation test for determination of hardness and other materials parameters for the following three ranges: macro range: 2 N ≤ F ≤ 30 kN; micro range: 2 N > F; h > 0,2 µm; and nano range: h ≤ 0,2 µm.
For the nano range, the mechanical deformation strongly depends on the real shape of indenter tip and the calculated material parameters…
Metallic materials — Instrumented indentation test for hardness and materials parameters — Part 3: C...
ISO 14577-3:2015 specifies a method for the calibration of reference blocks to use for the indirect verification of testing machines for the instrumented indentation test as specified in ISO 14577‑2:2015.
An adhesion evaluation method for microcircuits on PCB (Printed Circuit Board) by scratch test
This document describes a method for measuring adhesion strength between microcircuits and substrates by scratching with the wedged-shape diamond stylus. Using the traditional adhesion test, it is difficult to evaluate the adhesion strength of the microcircuits with a narrower scratching stylus.
During the test, applying stylus force is constant or progressive and normal to the surface. This…
Determination of the resistance to gas explosions of passive fire protection materials — Part 2: Div...
ISO 23693 part 1 aims to simulate the mechanical loads that could be imparted to passive fire protection (PFP) materials and systems by explosions resulting from the ignition of releases of flammable gas, pressurised liquefied gas, flashing liquid fuels or dust that may precede a fire. Explosions can give rise to pressure and drag forces. Damage to PFP materials and systems in an explosion can…
Metallic materials — Instrumented indentation test for hardness and materials parameters — Part 2: V...
ISO 14577-2:2015 specifies the method of verification and calibration of testing machines for carrying out the instrumented indentation test in accordance with ISO 14577‑1:2015.
It describes a direct verification method for checking the main functions of the testing machine and an indirect verification method suitable for the determination of the repeatability of the testing machine. There is a…
Oil and gas industries including lower carbon energy — Specific requirements for offshore structures...
ISO 19901-1:2015 gives general requirements for the determination and use of meteorological and oceanographic (metocean) conditions for the design, construction and operation of offshore structures of all types used in the petroleum and natural gas industries.
The requirements are divided into two broad types:
- those that relate to the determination of environmental conditions in general,…
