Water reuse in urban areas — Guidelines for benefit evaluation of reclaimed water use
Water shortages are one of the most crucial treats to sustainable development of society. Reclaimed water is considered as a safe, reliable and sustainable water source to satisfy water demands in many water-scarce areas.
This International Standard is intended to standardize the benefit evaluation of reclaimed water use, guiding the progress of planning, designing, operating, management and…
Space systems — Measured parameters at firing bench and flight tests of liquid rocket engines
ISO 16694:2015 applies to all types of liquid rocket engines for expendable launch systems and satellites:
a) Combustible fuel (including cryogenic);
b) Large-thrust, multiple component engines, with and without afterburning;
c) Low-thrust engines, one component (mono-propellant) and two-component (bi-propellant).
This International Standard establishes a list of parameters to be…
Cryogenic vessels — Centrifugal pumps for cryogenic service
ISO 24490:2016 specifies the minimum requirements for the design, manufacture and testing of centrifugal pumps for cryogenic service.
ISO 24490:2016 does not apply to reciprocating pumps.
This International Standard also gives guidance on the design of installations (see Annex A).
It does not specify requirements for operation or maintenance.
NOTE For general requirements for materials used in…
Hydraulic fluid power — Fluid contamination — Determination of particulate contamination by the coun...
This International Standard specifies methods for determining the level of particulate contamination in liquids used in hydraulic systems by counting the number of particles deposited on the surface of a membrane filter using an optical microscope. It includes particle counting by two manual methods and image analysis, using either transmitted or incident lighting systems.
Particle sizes greater…
The proposed International Standard “Impact assessment for museums” is planned as follow-up to ISO 18461 "Information and documentation - International museum statistics" and ISO 21246 “Information and documentation – Key indicators for museums”. Its purpose is to define and describe methods for assessing and measuring the impact of museums on individuals and on society.
The methods…
Gas welding equipment — Part 1: Line pressure regulators and line pressure regulators with flow-mete...
This International Standard specifies requirements for line pressure regulators and line pressure regulators with flow-metering devices to be connected to industrial gas distribution pipelines of
- compressed gases and Carbon Dioxide up to 60 bar (6 MPa),
- acetylene up to 1.5 bar (0.15 MPa),
- liquefied petroleum gases (LPG),
- methylacetylene-propadiene mixtures (MPS)
for use in welding,…
Gas welding equipment — Decomposition blockers for high-pressure acetylene
This International Standard establishes the general specifications, requirements and tests for decomposition blockers located on the high-pressure side in battery vehicles and gas containers as defined in EN 13807 or in acetylene bundles as defined in ISO 10961 or in filling systems.
Tyre abrasion rate measurement methods — Part 2: Indoor test method by using an abrasion tester on e...
Scope of the proposed deliverable.
This international standard (part 1 or part 2) specifies the method for measuring tread abrasion mass loss of a candidate tyre per unit distance travelled, under loaded conditions, by using vehicles on road (part 1) or an external drum tester (part 2).
Each test method specified in Part 1 and Part 2 measures abrasion performance of a candidate tyre on the…
