Soil quality — Determination of particle size distribution in mineral soil material — Method by siev...
This document specifies a basic method of determining the particle size distribution applicable to a wide range of mineral soil materials, including the mineral fraction of organic soils. It also offers procedures to deal with the less common soils mentioned in the introduction. This document has been developed largely for use in the field of environmental science, and its use in geotechnical…
Determination of the resistance to gas explosions of passive fire protection materials — Part 3: Tub...
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 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 and damage to PFP materials in a gas explosion can be caused by the direct…
Electrical requirements for lifts, escalators and moving walks — Part 2: Electromagnetic compatibili...
This document specifies the immunity performance criteria and test levels for apparatus used in lifts, escalators and moving walks which are intended to be permanently installed in buildings including the basic safety requirements in regard to their electromagnetic environment. These levels represent essential EMC requirements.
This document refers to EM conditions as existing in residential,…
Rubber compounding ingredients — Carbon black — Determination of aggregate size distribution by disc...
ISO 15825:2017 specifies a method for determining the size distribution of carbon black aggregates, using a disc centrifuge photosedimentometer. This technique is based on the hydrodynamic behaviour of carbon black in a centrifugal field. The determination of the aggregate size distribution is important in the evaluation of carbon black used in the rubber industry.
Life-threatening components of fire — Part 1: Guidelines for the estimation of time to compromised t...
This International Standard is one of many tools available for use in fire safety engineering. It is intended to be used in conjunction with models for analysis of the initiation and development of fire, fire spread, smoke formation and movement, chemical species generation, transport and decay, and people movement, as well as fire detection and suppression. This International Standard is to be…
