Technical committeeTypeAcronymISO 12669CommitteePublished year2017Description
ISO 12669 specifies a method of determining the required cleanliness level of a hydraulic system, that is, the most appropriate fluid cleanliness level for an operating hydraulic system based upon the individual requirements of that system.
It is applicable to systems where the level of fluid cleanliness is expressed in accordance with ISO 4406, although conversion to other contamination coding systems is possible.
It is applicable to both high and low pressure fluid power systems and also lubrication systems.
It does not include the effects of soft deformable particles that can be generated by thermal decomposition of the hydraulic fluid.

Technical committeeTypeAcronymISO 12405-4CommitteePublished year2018Description
This document specifies test procedures for the basic characteristics of performance, reliability and electrical functionality for the battery packs and systems for either high-power or high-energy application. Unless otherwise stated, the test applies to both applications. NOTE 1 Typical applications for high-power battery packs and systems are hybrid electric vehicles (HEVs) and some type of fuel cell vehicles (FCVs). NOTE 2 Typical applications for high-energy battery packs and systems are battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs) and some type of fuel cell vehicles (FCVs). NOTE 3 Testing on cell level is specified in IEC 62660 series.

This document establishes methods for:
— validating equipment used to prepare secondary calibration suspensions for automatic particle counters;
— performing online secondary calibration of automatic particle counters;
— matching two or more online particle counters, i.e. to count the same number of particles at a given size by two APCs associated online;
— validating online particle counting systems with and without online dilution as used, for example, to measure the filtration efficiency of a hydraulic filter as described in the multi-pass filter test in ISO 16889.

Technical committeeTypeAcronymISO 11500CommitteePublished year2008Description
ISO 11500:2008 specifies an automatic particle-counting procedure for determining the number and sizes of particles present in hydraulic-fluid bottle samples of clear, homogeneous, single-phase liquids using an automatic particle counter (APC) that works on the light-extinction principle.
ISO 11500:2008 is applicable to the monitoring of the cleanliness level of fluids circulating in hydraulic systems, the progress of a flushing operation, the cleanliness level of support equipment and test rigs and the cleanliness level of packaged stock.

Technical committeeTypeAcronymISO 11171CommitteePublished year2020Description
This document specifies procedures for the following:
a) primary particle-sizing calibration for particle sizes 1 µm(c) and larger, sensor resolution and counting performance of liquid automatic particle counters that are capable of analysing bottle samples;
b) secondary particle-sizing calibration using suspensions verified with a primary calibrated APC;
c) establishing acceptable operation and performance limits;
d) verifying particle sensor performance using a test dust;
e) determining coincidence and flow rate limits.
This document is applicable for use with hydraulic fluids, aviation and diesel fuels, engine oil and other petroleum-based fluids. This document is not applicable to particle-sizing calibration using NIST SRM 2806b primary calibration suspensions.

Technical committeeTypeAcronymISO 11170CommitteePublished year2013Description
ISO 11170:2013 defines a sequence of tests for verifying filter elements. It can be used to check their hydraulic, mechanical and separation characteristics.
ISO 11170:2013 is not intended to qualify a filter for a particular duty or replicate conditions of service. This can only be done by a specific test protocol developed for the purpose, including actual conditions of use (e.g. the operating fluid).
The procedure in ISO 11170:2013 is applicable to individual fluids or types of fluids that have similar chemistry.

ISO 10816-21:2015 specifies the measurement and evaluation of mechanical vibration of wind turbines and their components by taking measurements on non-rotating parts. It applies to horizontal axis wind turbines with mechanical gearbox and rated generator output exceeding 200 kW and the following design and operational characteristics: a) installation on supporting systems (tower and foundation) made of steel and/or concrete; b) horizontal axis rotor with several rotor blades; c) rotor bearing separate from or integrated into the gearbox; d) generators driven via gearbox; e) generators of the synchronous or asynchronous type (mostly equipped with 4-pole generator); f) generators with only a fixed pole number or which are pole-changeable for speed adjustment; g) output control by rotor blades (pitch or stall wind turbines); h) generator coupled to the power grid via converter or directly.

Technical committeeTypeAcronymISO 10771-1CommitteePublished year2015Description
ISO 10771-1:2015 specifies a method of fatigue testing the pressure-containing envelopes of components used in hydraulic fluid power systems under sustained steady cyclic internal pressure loads.
This part of ISO 10771 is only applicable to component pressure-containing envelopes that
- are manufactured from metals,
- are operated at temperatures that exclude creep and low-temperature embrittlement,
- are only subjected to pressure-induced stresses,
- are not subjected to loss of strength due to corrosion or other chemical action, and
- might include gaskets, seals, and other non-metallic components; however, these are not considered part of the pressure-containing envelope being tested (see 5.7).
ISO 10771-1:2015 does not apply to piping as defined in ISO 4413 (i.e. connectors, hose, tubing, pipe). See ISO 6803 and ISO 6605 for methods of fatigue testing of piping devices.
ISO 10771-1:2015 establishes a general test method that is applicable for many hydraulic fluid power components, but additional requirements or more specific methods that can be required for particular components are contained in the annexes or other standards.
Test pressure is to be determined by the user. See ISO/TR 10771‑2 for a possible rating method.
