Lubricants - Determination of aerobic biological degradation of fully formulated lubricants in an aqueous solution - Test method based on CO2-production
SIST EN 17181:2019

This document specifies a procedure for determining the degree of aerobic degradation of fully formulated lubricants. The organic material in a fully formulated lubricant is exposed in a synthetic aqueous medium under laboratory conditions to an inoculum from activated sludge.
Biodegradation resulting in mineralisation of the organic material can be determined by measuring released CO2 in a total organic carbon (TOC-) analyser. In contrast to existing test methods measuring released CO2 this method uses a precise preparation procedure for non-water soluble organic material.
The above mentioned method applies to fully formulated lubricants which
a)   are water-soluble, non-water soluble or emulsifiable, and
b)   are not toxic and not inhibitory to the test microorganisms at the test concentration.
The presence of inhibitory effects is determined as specified in this document.
This test method is focused on fresh water as test medium. Tests in sea water are currently not included in this method, but may be introduced later.

Liquid petroleum products - Bio-lubricants - Criteria and requirements of bio-lubricants and bio-based lubricants
SIST EN 16807:2016

This European Standard specifies the term bio-lubricant and minimum requirements for all kinds of bio-lubricants and bio-based lubricants, while e.g. the EEL [4] refers to specific bio-lubricant families.
This European Standard also briefly describes relevant test method needs with respect to the characterization of bio-lubricants. It presents recommendation for related standards in the field of biodegradability, product functionality and the amount of different renewable raw materials and/or different bio-based contents used during manufacturing of such bio-lubricants forming one product group.

Determination of flash point - Pensky-Martens closed cup method (ISO 2719:2016)
SIST EN ISO 2719:2016

ISO 2719:2016 describes three procedures, A, B and C, using the Pensky-Martens closed cup tester, for determining the flash point of combustible liquids, liquids with suspended solids, liquids that tend to form a surface film under the test conditions, biodiesel and other liquids in the temperature range of 40 °C to 370 °C.
CAUTION - For certain mixtures no flash point, as defined, is observed; instead a significant enlargement of the test flame (not halo effect) and a change in colour of the test flame from blue to yellowish-orange can occur. Continued heating can result in significant burning of vapours outside the test cup, and can be a potential fire hazard.
NOTE 1       Although, technically, kerosene with a flash point above 40 °C can be tested using this International Standard, it is standard practice to test kerosene according to ISO 13736.[5] Similarly, lubricating oils are normally tested according to ISO 2592[2].
Procedure A is applicable to distillate fuels (diesel, biodiesel blends, heating oil and turbine fuels), new and in-use lubricating oils, paints and varnishes, and other homogeneous liquids not included in the scope of Procedures B or C.
Procedure B is applicable to residual fuel oils, cutback residua, used lubricating oils, mixtures of liquids with solids, liquids that tend to form a surface film under test conditions or are of such kinematic viscosity that they are not uniformly heated under the stirring and heating conditions of Procedure A.
Procedure C is applicable to fatty acid methyl esters (FAME) as specified in specifications such as EN 14214[11] or ASTM D6751[13].
ISO 2719:2016 is not applicable to water-borne paints and varnishes.
NOTE 2       Water-borne paints and varnishes can be tested using ISO 3679[3]. Liquids containing traces of highly volatile materials can be tested using ISO 1523[1] or ISO 3679.

Petroleum products - Determination of content of Benzo(a)pyrene (BaP) and selected polycyclic aromatic hydrocarbons (PAH) in extender oils - Procedure using double LC cleaning and GC/MS analysis
SIST EN 16143:2013

This European Standard specifies a procedure for the determination of the content of benzo[a]pyrene (BaP) in extender oils which are commonly used in the rubber industry for the production of tyres or parts of tyres. The method also yields the sum of the eight individual polycyclic aromatic hydrocarbons (PAHs) listed in Table 1.
The procedure has been tested and verified for the PAHs listed in Table 1 (those required by the European Commission [1]) and additional PAHs as listed in Table A.2.
Analysis of other PAHs is possible in principle, but sufficient quality assurance performed by the user is necessary to secure the analysis.
The application range for this method is from approximately 4 mg/kg to approximately 15 mg/kg for the eight individual PAHs and from approximately 0,5 mg/kg to approximately 2 mg/kg for BaP.
NOTE 1   The intended working range for this method is in the 0,1 mg/kg to 15 mg/kg range. For the lower levels precision has not yet been established.
NOTE 2   For the purposes of this European Standard, the term "% (m/m)" is used to represent the mass fraction (...).

Liquid petroleum products - Bio-lubricants - Recommendation for terminology and characterisation of bio-lubricants and bio-based lubricants
SIST-TP CEN/TR 16227:2011

This Technical Report gives information about bio-lubricants and recommendations for bio-lubricant (and bio-based lubricant) related terminology. These recommendations are based on a discussion of commonly used terms in this field.
This Technical Report also briefly describes the current test methods in relation to the characterization of bio-lubricants. It presents recommendation for related standards in the field of biodegradability, product functionality, impact on greenhouse gas emissions and te amount of different renewable raw materials an/or different biobased contents used during manufacturing of such bio-lubricants forming one product group.
The criteria of the European Ecolabel for Lubricants ("EEL") [2] includes the terms discussed in this paper.
NOTE 1   The European Lead Market Initiative ("LMI") [3] defines the term "bio-based" as described in Table 1. It is important to mention that "bio-based" does not imply "biodegradable". In addition, "biodegradable" does not imply the use of "bio-based" material.
NOTE 2   For the purposes of this European Technical Report, the term "% (m/m)" is used to represent the mass fraction.

Liquid petroleum products - Determination of nickel and vanadium content - Inductively coupled plasma optical emission spectrometry method (ICP OES)
SIST EN 15944:2011

This European Standard specifies an inductively coupled plasma optical emission spectrometry (ICP OES) method for the determination of nickel content in the range 4 mg/kg to 55 mg/kg and of vanadium content in the range 4 mg/kg to 150 mg/kg in fuel oils and residual fuel oils.
NOTE 1   Nickel content can be determined from 2 mg/kg to 4 mg/kg and vanadium content can be determined from 1 mg/kg to 4 mg/kg. However, the precision was not established as no samples with nickel and vanadium contents in these ranges were included in the interlaboratory test. Nickel and vanadium contents higher than those reported can be determined after sample dilution. However, the precision was not established for diluted samples.
NOTE 2   For the purposes of this European Standard, the term "% (V/V)" is used to represent the volume fraction (phi).
WARNING - The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
