This document specifies a method for the assessment of the persistence of a flame applied to the edge of a wick of non-flammable material immersed in fire-resistant fluid. The test relates to the bulk behaviour of a fluid, which may provide pertinent information for safe transportation and storage.

This test does not determine the behaviour of a spray of fire-resistant fluid (see Introduction).

This document establishes one of two basic measures of fire-resistance, and may be called up in regulations governing the use of fire resistant hydraulic fluids under ISO 12922 [1].

This document does not apply to certain water-containing fluids or emulsions that do not adhere to the test board.

This document specifies the methodology for the design of an Interlaboratory Study (ILS) and calculation of precision estimates of a test method specified by the study. In particular, it defines the relevant statistical terms (Clause 3), the procedures to be adopted in the planning of ILS to determine the precision of a test method (Clause 4), and the method of calculating the precision from the results of such a study (Clauses 5 and 6).

The procedures in this document have been designed specifically for petroleum and petroleum related products, which are normally considered as homogeneous. However, the procedures described in this document can also be applied to other types of homogeneous products. Careful investigations are necessary before applying this document to products for which the assumption of homogeneity can be questioned.

This document specifies the methodology for the application of precision estimates of a test method derived from ISO 4259-1. In particular, it defines the procedures for setting the property specification limits based upon test method precision where the property is determined using a specific test method, and in determining the specification conformance status when there are conflicting results between supplier and receiver. Other applications of this test method precision are briefly described in principle without the associated procedures.

1.1 This document describes the design, use and calibration of volumetric measures (capacity measures)which are intended for use in fixed locations in a laboratory or in the field. It also covers portable and mobilemeasures. The scope covers applications particularly, but not exclusively, in the petroleum industry.Volumetric measures are classified as test measures or prover tanks depending on capacity and design.

1.2 The document excludes pressurised measures as used for LPG and LNG and measures for cryogenicliquids. Measures described in this document are primarily designed, calibrated and used to measurevolumes "to deliver", i.e. wetted and drained for a specified time before use. Many of the provisions willhowever apply equally to measures which are used "to contain", i.e. to measure a volume using a clean anddry measure.

1.3 Annex A provides a reference for formulae describing the properties of water and other materials used to define volume. This includes density, thermal expansion, compressibility and viscosity for pure, impureand saline water. It also provides property information for hydrocarbon liquids and materials used toconstruct measures.

1.4 Guidance is given regarding commonly expected uncertainties and calibration specifications.

This International Standard specifies a method for the determination of the existent gum content of aviation

fuels, and the gum content of motor gasolines or other volatile distillates. It includes the determination of

products containing alcohol (up to 85 % in volume) and ether type oxygenates and deposit control additives.

For non-aviation fuels, a procedure for the determination of the heptane-insoluble portion of the residue is also

described.

CAUTION-This method is not intended for the testing of gasoline components, particularly those

with a high percentage of low-boiling unsaturated compounds, as they may cause explosions during

evaporation.

NOTE The true significance of this test method for determining gum in motor gasoline is not firmly established. It has

been proven that high gum content can cause induction-system deposits and sticking of intake valves, and in most

instances it can be assumed that low gum content will ensure absence of induction-system difficulties. The user should,

however, realize that the test is not of itself correlative to induction-system deposits. The primary purpose of the test, as

applied to motor gasoline, is the measurement of the oxidation products formed in the sample prior to or during the

comparatively mild conditions of the test procedure. Since many motor gasolines are purposely blended with non-volatile

oils or additives, the heptane extraction step is necessary to remove these from the evaporation residue so that the

deleterious material, gum, may be determined. With respect to aviation turbine fuels, large quantities of gum are indicative

of contamination of fuel by higher boiling oils or particulate matter and generally reflect poor handling practices in

distribution downstream of the refinery.

Specifies a test method for measuring the ability of petroleum oils or synthetic fluids to separate from water at a specified temperature (the normal test temperature is (54 ± 1) °C, but this may be increased to (82 ± 1) °C for products with a viscosity above 90 mm^2 at 40 °C, and other test temperatures may also be specified). The method was developed specifically for steam-turbine oils in the viscosity range 32 mm^2 to 95 mm^2 at 40 °C, but it may be used to test oils of other types and viscosity ranges, and also to test synthetic fluids.

This International Standard specifies a method for the estimation of the ability of a petroleum-type steam turbine oil

to be separated from entrained air.

NOTES

1 The impinger method described in this International Standard is used for determining the air-release ability of the oils tested.

Air bubbles dispersed in the oil influence the compressibility and can cause malfunctions. This method may not be suitable for

ranking oils in applications where residence times are short and gas contents high.

2 Agitation of lubricating oil with air in equipment such as bearings, couplings, gears, pumps and oil return lines, may produce

a dispersion of finely divided air bubbles in the oil. If the residence time in the reservoir is too short to allow the air bubbles to

rise to the oil surface, a mixture of air and oil will circulate through the lubricating oil system. This may result in an inability to

maintain oil pressure (particularly with centrifugal pumps), incomplete oil films in bearings and gears, and poor hydraulic

system performance or failure.

3 This test measures the time for the entrained air content to fall to the relatively low value of 0,2 % (V/V) under a

standardized set of test conditions, and hence permits the comparison of the ability of oils to separate entrained air under

conditions where a separation time is available. Although the significance of the test results is not fully established, sponginess

and lack of sensitivity of the control systems of some turbines may be related to the air release properties of the oil. System

design and system pressure are other variables.

4 For the purposes of this International Standard, the expression “%(V/V)” is used to represent the volume fraction of a

material.

This part of ISO 12176 specifies an encoding system for data of components, assembly methods and jointing operations for polyethylene (PE) piping systems for gas, water and other industrial uses. These data may be used in a traceability system and/or used to perform the fusion of components by using equipment as specified in ISO 12176-1 and in ISO 12176-2.

This encoding system is elaborated under the, ISO/IEC 16022, ISO/IEC 18004, ISO/IEC 24778[1] to which it refer for establish code type (e.g.: QR code) and its coding characteristics.

Examples of data to be encoded are: fusion cycle(s), traceability of manufactured product, other manufacturer information that may also be given on web-sites (1) eg.: web site, voluntary certificate(s) of quality, approval(s), etc.
