Ships and marine technology -- Lubricating and hydraulic oil systems -- Guidance for sampling to determine cleanliness and particle contamination

ISO 28523:2009 specifies methods for dynamic and static extraction of fluid samples from lubricating and hydraulic oil systems. A correct execution of the sampling is essential when analysing fluids from lubricating and hydraulic oil systems. In order to achieve reliable and comparable analysis results, the sampling must be performed under defined conditions and operating environment. When the system has reached its operating temperature, a representative sample is extracted from where the fluid is in a turbulent flow condition. This method is called dynamic sampling. If this is not possible, the sample can be extracted from the system tank. This method is called static sampling. ISO 28523:2009 specifies methods for both dynamic and static sampling in connection with collection in bottles. For extraction of samples through a filtration kit for comparison with “master slides”, reference is made to the manuals from the suppliers of such equipment.

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 28523 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee

SC 3, Piping and machinery.

particle contamination
1 Scope

This International Standard specifies methods for dynamic and static extraction of fluid samples from

lubricating and hydraulic oil systems.

A correct execution of the sampling is essential when analysing fluids from lubricating and hydraulic oil

systems.

In order to achieve reliable and comparable analysis results, the sampling must be performed under defined

conditions and operating environment.

When the system has reached its operating temperature, a representative sample is extracted from where the

fluid is in a turbulent flow condition. This method is called dynamic sampling. If this is not possible, the sample

can be extracted from the system tank. This method is called static sampling.
NOTE Particles > 20 µm settle quickly during static sampling.

This International Standard specifies methods for both dynamic and static sampling in connection with

collection in bottles.

For extraction of samples through a filtration kit for comparison with “master slides”, reference is made to the

manuals from the suppliers of such equipment.
2 Normative references

The following referenced documents are indispensable for the application of this document. For dated

references, only the edition cited applies. For undated references, the latest edition of the referenced

document (including any amendments) applies.

ISO 3722, Hydraulic fluid power — Fluid sample containers — Qualifying and controlling cleaning methods

ISO 4021, Hydraulic fluid power — Particulate contamination analysis — Extraction of fluid samples from lines

of an operating system

ISO 4406, Hydraulic fluid power — Fluids — Method for coding the level of contamination by solid particles

3 Dynamic sampling
3.1 Rigging the sampling device

If it is possible to mount the sampling device on a section of the system pipe with a turbulent flow, a sampling

device as specified in Figure 1 is used.
