Carbon footprint for seafood — Product category rules (CFP-PCR) for macroalgae
This document specifies requirements for calculating the carbon footprint specific to farmed macroalgae product category rules (CFP–PCR). This methodology builds on the requirements of International Standards for life cycle assessment (LCA) and products’ carbon footprints.
This document is applicable to the calculation and communication of farmed macroalgae products’ carbon footprints from…
Reaction to fire tests for floorings — Part 1: Determination of the burning behaviour using a radian...
This part of ISO 9239 specifies a method for assessing the wind-opposed burning behaviour and spread of flame of horizontally mounted floorings exposed to a heat flux radiant gradient in a test chamber, when ignited with pilot flames. Annex A gives details of assessing the smoke development, when required.
This method is applicable to all types of flooring, e.g. textile carpet, cork, wood,…
Safety and control devices for gas burners and gas-burning appliances — Particular requirements — Pa...
ISO 23551-10:2016 specifies the safety, design, construction and performance requirements and testing for automatic vent valves (hereafter referred to as "valves") for use with gas burners, gas appliances burning one or more gaseous fuels.
It is applicable to valves with declared maximum inlet pressures up to and including 500 kPa (5 bar) of nominal connection sizes up to and including…
Safety of toys — Part 4: Activity toys for domestic use
This part of ISO 8124 specifies requirements and test methods for activity toys for domestic family useintended for children under 14 years to play on or in.Products covered by this part of ISO 8124 include swings, slides, seesaws, carousels, rocking toys,climbing frames, fully enclosed toddler swing seats and other products intended to bear the mass of oneor more children.Products not included…
Colloidal systems — Methods for zeta-potential determination — Part 2: Optical methods
This part of ISO 13099 specifies two methods of measurement of electrophoretic mobility of particles suspended in a liquid: video microscopy and electrophoretic light-scattering. Estimation of surface charge and determination of zeta-potential can be achieved from measured electrophoretic mobility using proper theoretical models, which are described in detail in ISO 13099-1.
ISO 22412:2017 specifies the application of dynamic light scattering (DLS) to the measurement of average hydrodynamic particle size and the measurement of the size distribution of mainly submicrometre-sized particles, emulsions or fine bubbles dispersed in liquids. DLS is also referred to as "quasi-elastic light scattering (QELS)" and "photon correlation spectroscopy (PCS),"…
Specifies methods of determining the sulfate and pyrite sulfur contents of coals, including brown coals and methods of calculating the amount of organic sulfur present. Replaces the first edition.
Rough-terrain trucks — Safety requirements and verification — Part 2: Slewing trucks
ISO 10896-2:2016 specifies general safety requirements for slewing rough-terrain variable-reach trucks (hereafter known as "trucks"), consisting of a lower chassis with a slewing upper structure equipped with a telescopic lifting means (pivoted boom), on which a load handling device (e.g., carriage and fork arms) is typically fitted. Fork arms and other integrated attachments are…
Water quality — Radium-226 — Part 4: Test method using alpha spectrometry
This document specifies methods to determine 226Ra in all types of waters by alpha spectrometry.
The methods are applicable to test samples of supply/drinking water, rainwater, surface and ground water, marine water, as well as cooling water, industrial water, domestic, and industrial wastewater after proper sampling and handling, and test sample preparation.
The detection limit depends on the…
