Rubber, raw — Determination of volatile-matter content — Part 1: Hot-mill method and oven method
This document specifies two methods for the determination of volatile-matter content in raw rubbers by using a hot mill or an oven.
These methods are applicable to the determination of the volatile-matter content in the “R” group of rubbers listed in ISO 1629. These are rubbers having an unsaturated carbon chain, for example natural rubber and synthetic rubbers derived at least partly from di-…
Wheels and rims for pneumatic tyres — Vocabulary, designation and marking
This document presents a vocabulary of terms related to, and systems for the designation and marking of, wheels and rims intended for use with pneumatic tyres. The intention is to define fundamental wheel and rim terms rather than provide a comprehensive tabulation of all wheel design features. Also specified are the content, location and minimum size of the wheel and rim marking, with the…

High-voltage switchgear and controlgear - Part 215: Phase comparator used with VDIS
IEC 62271-215:2021 is applicable to phase comparators designed to be plugged into the testing points of a voltage detecting and indicating system (VDIS) according to IEC 62271-213, to give an indication of the result of a phase comparison.
The main usage is to provide a clear evidence of the phase relationship between two energized parts of a high-voltage network, at the same nominal voltage and…
Global maritime distress and safety system (GMDSS) - Part 2: Cospas-Sarsat EPIRB - Emergency positio...
IEC 61097-2:2021(E) specifies the minimum performance requirements, technical characteristics and type-testing requirements of the emergency position-indicating radio beacon used in the Cospas-Sarsat satellite system (EPIRB), as required by the International Convention for Safety of Life at Sea (SOLAS) as amended, and which is associated with IEC 60945. When a requirement in this document is…
High-voltage switchgear and controlgear - Part 213: Voltage detecting and indicating system
IEC 62271-213:2021 is applicable to the voltage detecting and indicating system (VDIS) to be installed on indoor and outdoor high-voltage equipment.
The VDIS as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts (main circuit).
This first edition cancels and replaces the first edition of IEC 61243-5…
Tobacco and tobacco products — Determination of water content — Karl Fischer method
This document specifies a method for the determination of water content by the Karl Fischer method. It is applicable to raw tobacco as well as tobacco taken from finished products. The method is suitable for water contents ranging from a mass fraction of at least 2 % to 55 %.
Soil and waste — Determination of Chromium(VI) in solid material by alkaline digestion and ion chrom...
This document specifies the determination of Cr(VI) in solid waste material and soil by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr(VI)-mass fractions in solids higher than 0,1 mg/kg.
NOTE In case of reducing or oxidising waste matrix no valid Cr(VI) content can be reported.
Plugs, fixed or portable socket-outlets and appliance inlets for industrial purposes - Part 1: Gener...
IEC 60309-1:2021 applies to plugs, fixed or portable socket-outlets and appliance inlets hereinafter referred to as accessories, with a rated operating voltage not exceeding 1 000 V DC or 1 000 V AC with a frequency not exceeding 500 Hz and a rated current not exceeding 800 A, primarily intended for industrial use, either indoors or outdoors.
This fifth edition cancels and replaces the fourth…
