Jewellery and precious metals — Determination of silver — ICP-OES method using an internal standard ...
This document specifies an analytical method for the determination of silver on a material considered homogeneous. The silver content of the samples lies preferably between 50 ‰ (parts per thousand) and 990 ‰ (parts per thousand). Fineness above 999,0 ‰ can be determined using a spectroscopy method by difference (e.g. ISO 15096).
NOTE Lower contents of silver can be analyzed with this method.

Measurement of radioactivity in urine-238Pu, 239Pu and 240Pu-Test method using alpha spectrometry an...
This proposed standard is applicable the analysis of plutonium (238Pu, 239Pu and 240Pu) in urine, which can be used for the internal dose monitoring of the public, occupational and rescue under accident conditions. The range of radioactivity are 1×10-4 Bq/L to 0.1 Bq/L for 238Pu and 1×10-5 Bq/L to 1×10-2 Bq/L for 239Pu and 240Pu.
This standard introduces methods for the determination of…

Steel structures — Structural bolting — Test method to determine parameters of bolt tightening proce...
This test method is to be used only if no rules and parameters for tightening exist, e.g. for pretensioning of stainless steel bolting assemblies, or when bolts are pretensioned by turning the head.
This test method establishes a bolt tightening qualification procedure (BTQP) which provides design and execution rules for pretensioning of stainless steel and carbon steel bolting assemblies with…
Rubber hoses and hose assemblies for aircraft ground fuelling and defuelling — Specification
ISO 1825:2017 specifies the dimensions and construction of, and requirements for, four types of hose and hose assembly for use in all operations associated with the ground fuelling and defuelling of aircraft.
All four types are designed for:
a) use with petroleum fuels having an aromatic-hydrocarbon content not exceeding 30 % by volume;
b) operation within the temperature range of −30 °C to +65 °…
