This International Standard specifies a rapid method for extraction of oil and for preparation of the methyl esters of fatty acids. The methyl esters thus obtained can be used for gas chromatography.

This International Standard is applicable to the following oilseeds: rape, sunflower, soya beans, mustard, linseed.

NOTE          Applying this rapid method to high erucic acid content rapeseed leads to an overestimation of erucic acid content by approximately a mass fraction of 1 %. This difference was observed in the study [6] and may be due to the partial extraction of the oil from the sample (yield around 70%). High content of erucic acid in triglycerides could increase their solubility in hexane because of the lipophilic effect of the carbon long-chain (C22). However, as this effect was not checked on a large set of high erucic rapeseed samples, it is not recommended to apply a correction factor to the erucic acid content when analysing high erucic acid rapeseed.

This International Standard describes simplified methods for taking samples of solid biofuels in small
scale applications and stores including preparation of sampling plans and certificates. Usually the focus
is on stores with a size of 100 t. The standard is applicable to the following solid biofuels:
- fine (up to about 10 mm nominal top size) and regularly-shaped particulate materials that can be
sampled using a scoop or pipe, e.g. sawdust, olive stones and wood pellets;
- coarse or irregularly-shaped particulate materials (up to 200 mm nominal top size) that can be
sampled using a fork or shovel, e.g. wood chips, hog fuel and nut shells;
- large pieces (above 200 mm nominal top size) which are picked manually (e.g. firewood and
briquettes);
It may be possible to use this standard on other solid biofuels. The methods described in this
International Standard may be used, for example, when a sample is to be tested for moisture content,
ash content, calorific value, bulk density, mechanical durability, particle size distribution, ash melting
behaviour and chemical composition.
This International Standard can be used also for applications and stores ; > 100 t if the involved parties,
e.g. provider and consumer of a biofuel, agree with.
For sampling in general, if higher precision of analytical results are needed or in doubt if this standard
is applicable ISO 18135 should be used.

This document establishes a system of designation for thermoplastic polyester (TP) material, which can be used as the basis for specifications. It covers polyester homopolymers for moulding and extrusion based on poly(ethylene terephthalate) (PET), poly(butylene terephthalate) (PBT), poly(cyclohexylenedimethylene terephthalate) (PCT), poly(ethylene naphthalate) (PEN), poly(butylene naphthalates) (PBN) and other TP-types and copolyesters of various compositions for moulding and extrusion.

The types of thermoplastic polyester are differentiated from each other by a classification system based on appropriate levels of the designatory properties:

a)     viscosity number;

b)    tensile modulus of elasticity;

and on information about the intended application and/or method of processing, important properties, additives, colorants, fillers and reinforcing materials.

This designation system is applicable to thermoplastic polyester homopolymers and copolymers. It applies to materials ready for normal use in the form of powder, granules or pellets, unmodified or modified by colorants, fillers and other additives. This document does not apply to the saturated polyester/ester and polyether/ester thermoplastic elastomers covered by ISO 20029.

It is not intended to imply that materials having the same designation give necessarily the same performance. This document does not provide engineering data, performance data or data on processing conditions which can be required to specify a material. If such additional properties are required, they are intended to be determined in accordance with the test methods specified in ISO 20028‑2, if suitable.

In order to designate a thermoplastic polyester material to meet particular specifications, the requirements are to be given in data block 5 (see 4.1).

This European Standard sets requirements for bio-based surfactants in terms of properties, limits, application classes and test methods. It lays down the characteristics and details for assessment of bio-based surfactants as to whether they:
- are fit for purpose in terms of performance related properties;
- comply with the requirements regarding the health, safety and environment which apply to general surfactants;
- are derived from a certain minimum percentage of biomass; and
- comply with at least similar sustainability criteria as comparable (non-bio-based) surfactants.
The criteria of the regulation on Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) [11] also apply to bio-based surfactants.
NOTE EN 16575 defines the term "bio-based" as derived from biomass and clarifies that "bio-based" does not imply "biodegradable". In addition, "biodegradable" does not necessarily imply the use of "bio-based" material.

This Technical Specification provides a method for the evaluation of the rinsing effectiveness of household clothes washing machines, washer dryers and commercial washing machines. The amount of residual linear alkylbenzene sulfonate surfactant (LAS) extracted from the unstained test swatches of the strips used in the washing performance test is determined. This is accomplished by measuring the ultraviolet (UV) light absorbance at the wavelength particular to LAS, a key ingredient of the detergent.
Assuming a fixed linear relationship between LAS amount and quantity of detergent mixture and using a concentration versus absorbance curve developed as part of this procedure, the absorbance values are then converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities. This assumption is done, because in the frame of this test it is not possible to determine the exact amount of LAS involved, even in the concentration curves, but only the amount of detergent used.
On the textiles, this linear relationship is not given, but it is nevertheless used to express the amount of LAS as determined by UV light absorbance measurements in terms of a detergent amount.
Using a concentration versus absorbance curve developed as part of this procedure, the absorbance values can then be converted into detergent concentrations, which together with the test solution mass data, yields detergent quantities.

This International Standard specifies, for ropes of different kinds, a method of determining each of the following characteristics:

linear density;

diameter;

lay length;

braid pitch;

elongation;

breaking force.

The linear density, lay length and braid pitch are measured with the rope under a specified tension called the reference tension, as specified in Annex A.

The elongation corresponds to the measured increase in length of the rope when the tension to which it is subjected is increased from an initial value (reference tension) to a value equal to 50 % of the minimum specified breaking strength of the rope.

The breaking force is the maximum force registered (or reached) during a breaking test on the test piece, carried out on a tensile testing machine with constant rate of traverse of the moving element. The breaking force values given in the tables of rope specifications are only valid when this type of testing machine is used.

When it is not possible to test the rope in full size, the method described in Annex B can be used, subject to agreement between the parties involved.

This International Standard also provides a method for measuring water repellence, lubrication and finish content, when requested by the customer.
