Measurement of DC magnetic, AC magnetic and AC electric fields from 1 Hz to 100 kHz with regard to e...
IEC 61786-2:2014 provides requirements for the measurement of quasi-static magnetic and electric fields that have a frequency content in the range 1 Hz to 100 kHz, and DC magnetic fields, to evaluate the exposure levels of the human body to these fields. Specifically, this standard gives requirements for establishing measurement procedures that achieve defined goals pertaining to human exposure.…
Double-capped LED lamps designed to retrofit linear fluorescent lamps - Safety specifications

Solid mineral fuels — Determination of Chlorine content
ISO/TS 18806:2014 specifies two methods (high temperature combustion and bomb combustion) for the determination of chlorine in solid mineral fuels. It is applicable to hard coals, brown coals, coke, and tailings.
The chlorine in the digestion solution can be determined using different methods, e.g. an ion-selective electrode, coulometric or potentiometric titration, spectrophotometry, or ion…
Jewellery — Determination of silver in 999 0/00 silver jewellery alloys — Difference method using IC...
ISO 15096:2014 specifies the analytical procedure for the determination of silver with a nominal content of at least 999 ? (parts per thousand) by measuring specific elements listed in Table A.1.
This International Standard specifies a method intended to be used as the recommended method for the determination of fineness in 999 ? silver alloys covered by ISO 9202.
Rubber latex, natural, concentrate — Determination of sludge content
ISO 2005:2014 specifies a method for the determination of the sludge content of natural rubber latex concentrate.
The method is not necessarily suitable for latices from natural sources other than Hevea brasiliensis.
It is not suitable for compounded latex or vulcanized latex.
Geotechnical investigation and testing — Laboratory testing of soil — Part 1: Determination of water...
ISO 17892-1:2014 specifies a method of determining the water content of soils.
It is applicable to the laboratory determination of the water (also known as moisture) content of a soil test specimen by oven-drying within the scope of geotechnical investigations. The water content is required as a guide to the classification of natural soils and as a control criterion in re-compacted soils, and is…
Geotechnical investigation and testing — Laboratory testing of soil — Part 2: Determination of bulk ...
ISO 17892-2:2014 specifies three methods for the determination of the bulk density of soils, comprising: a) linear measurement method; b) immersion in fluid method; c) fluid displacement method.
ISO 17892-2:2014 is applicable to the laboratory determination of the bulk density of soil within the scope of geotechnical investigations.
The linear measurement method is suitable for the determination…
Jewellery — Determination of gold in gold jewellery alloys — Cupellation method (fire assay)
ISO 11426:2014 specifies a cupellation method (fire assay) for the determination of gold in gold jewellery alloys. The gold content of the alloys should preferably lie between 333 and 999 parts per thousand (?).
The procedure is applicable specifically to gold alloys incorporating silver, copper, and zinc. Some modifications are indicated where nickel and/or palladium are present in the so-called…
Imaging materials — Magnetic hard drives used for image storage — Care and handling
ISO 18943:2014 concerns the storage, care, and handling of HDDs. It recommends handling procedures to maximise the effective life of the data written on magnetic HDDs. Faulty care and handling methods can cause damage to a disk and the contents written thereon. It also recommends storage practices to preserve both the hard disk media and the content encoded thereon.
The recommendations in this…
Luminaires - Part 2-20: Particular requirements - Lighting chains
IEC 60598-2-20:2014 specifies requirements for lighting chains fitted with series, parallel or a combination of series/parallel connected light sources for use either indoors or outdoors on supply voltages not exceeding 250 V. For combinations where rope lights (also known as sealed lighting chains) are included, see IEC 60598-2-21. This fourth edition cancels and replaces the third edition (2010…
