SIST EN 10245-1:2012
EN 10245-1:2011 (E) 5 Introduction This European Standard for organic coatings for steel wire covers the requirements of a general nature and applies also to coatings for which no specific requirements have been established in the subsequent parts of this standard. The subsequent parts of this standard deal more specifically with clearly defined coatings or groups of coatings. These coatings may have their own particular methods of application and their individual requirements which are specified in these parts of this standard, in other standards or in manufacturers data sheets. Because the standard specifies requirements and tests not only for the coating but also for the coating material, it has proved not practical to put all the requirements in one clause and all the tests in another one. Following structure has been chosen in order to limit complexity and to facilitate the use. In writing this series of standards consideration has been given to the nomenclature and transformation of organic coating materials as applied to steel wire products. These organic coating materials may, on application to wire and by their integration into the finished wire product, change their characteristics and properties. This standard specifies characteristics and tests not only for the organic coating but also for the coating materials both before and after their application to steel wire and wire products. In addition it specifies the requirements for performance levels and testing methods on organic coating material which have become an integral and permanent part of the finished wire product. Therefore it has proven not to be practical to put all requirements in one clause and all the tests in another one. To aid continuity and in order to limit complexity, the following structure has been chosen for this standard: Clause 4 deals with the characteristics and testing methods of organic coating material as supplied by the manufacturer for the purposes of its application to the wire product. Tests described in this section are intended to be carried out by the organic coating material manufacturer or the applicator before the coating operation. Clause 5 relates to the characteristics and testing methods for the "organic coating" when the organic coating material has been applied to and has become an integral part of the finished wire. Consequently tests are intended to be in the main carried out by the coating "applicators". Clause 6 defines the performance requirements and testing methods on the "organic coating" of the finished wire product, and where this is not possible, tests will be carried out on "coated" panels. 1 Scope This European Standard specifies the requirements for the characteristics and testing methods for organic coatings made of organic coating material suitable for the application on to steel wire and wire products of circular or other sections.
Other organic materials which are applied intentionally or otherwise such as oils, greases, waxes and temporary finishes which do not become integral or a permanent part of the finished wire product are excluded from this standard

The organic coating material may be applied directly to the surface of the steel wire or subsequent to a pre-treatment of the steel wire surface with a primary coating which can consist of inorganic or organic materials. For the purpose of this definition the steel wire/wire product may be coated with a non-ferrous metallic coating or not. 3.2 organic coating material material made essentially of organic compounds capable of covering the steel wire surface after suitable preparation NOTE The "organic coating materials" generally contain other matter such as pigments, fillers, plasticisers, lubricants and other additives which are specific to each organic coating material composition. SIST EN 10245-1:2012
EN 10245-1:2011 (E) 8 The organic coating materials may be applied using a liquid solution containing organic products capable of covering the surface with the desired organic coating material. The organic coating material may also be applied in the solid form, e.g. powder or in the form of granules. A powder coating is generally applied by depositing the powder on the wire/wire product and then sintering by melting the powder onto the wire product. Granules are applied to a wire by feeding them into an extruder and extruding the "organic coating" onto the wire substrate. Organic coating materials can be subdivided into several groups each having its own characteristic method of application. 3.2.1 thermoplastics materials materials having the specific property of softening when heated and hardening or solidifying when cooled, which as a process is reversible and allows a certain degree of recycling or reprocessing of the material NOTE These materials include PVC, nylon, polyethylene, polypropylene and the copolymer vinyl ethylene acetate. These materials may be applied by one of the following methods: electrostatic spraying, fluidized bed or extrusion. 3.2.2 thermosetting materials materials having the property of changing into much more infusible and insoluble product when hot polymerized by methods such as radiation, catalysts. etc.
NOTE Once polymerized and made insoluble they cannot be remelted. These materials include polyester and epoxy coatings. These materials are typically applied by electrostatic powder spray. 3.2.3 plastisols/organosols suspension of fine particles of inorganic materials such as resins, PVC, etc carried in an organic fluid or solvents NOTE After immersion or spraying, exposure to heat causes the plastisol to melt to form a solid continuous flexible organic coating. 3.2.4 paint material coloured with organic and sometimes inorganic components, dispersed in oils or water NOTE They are applied in liquid form to the surface of the wire and after air drying they form a continuous adherent film on the wire. Application is by brush, roller or spray (electrostatic or atmospheric) or by immersion. 3.2.5 varnish generally organic materials which are transparent or coloured with an oil, resin and solvent base, which are then air dried NOTE Application is the same as for paints (see 3.2.4). 3.2.6 lacquer synthetic organic transparent or coloured coating which generally dries to form a film after evaporation of the solvent 3.3 test piece part of the sample, with specified dimensions, machined or un-machined, brought to a required condition for submission to a given test NOTE
In certain cases, the test piece can be the sample itself or the rough specimen. SIST EN 10245-1:2012
EN 10245-1:2011 (E) 9 3.4 significant surface part of the total surface over which it shall be ensured that the "organic coating" complies with the specific requirements of the Standard 3.5 pre-treatment operation carried out on the wire/wire products before the final application of the organic coating material 3.6 shelf life period during which an organic coating material, securely packaged and stored according to the manufacturer's recommendations, may be kept from the time of manufacture to the actual use by the applicator and still retain the characteristics and properties as specified 3.7 meltflow index rate of extrusion of molten resins through a die of specified length and diameter under prescribed conditions of load and piston position in the barrel as the timed measurement is being made 3.8 manufacturer organisation which manufactures the organic coating material 3.9 applicator organisation which applies the organic coating material to the wire/wire product and transforms it into an organic coating which is an integral part of the finished wire product 3.10 specifier organisation issuing a contract specifying the particular properties and performance requirements of a finished wire/wire products covered with an organic coating NOTE The specifier is usually the purchaser of the finished wire product. 4 Requirements and testing methods for the organic coating material 4.1 General Many characteristics of organic coating materials prove difficult to measure. This is why a good number of characteristics in this European Standard relate to requirements for organic coating materials as supplied by the manufacturer. The manufacturer's data sheet may supply many of these characteristics. They shall also give the necessary information for traceability of the materials. 4.2 Requirements
4.2.1 Composition The manufacturer shall supply reference data for the qualification of the material. The organic coating material shall comply with the compositional characteristics specified at the time of the order. The specifications commonly include quantities and type of pigments, plasticizers, lubricants and other organic and inorganic materials agreed mutually. The manufacturer shall immediately notify the applicator of any subsequent change in the type and quantity of the constituent parts of the composition once this has been agreed between the two parties. The manufacturer shall also provide appropriate information for easy identification of the batches supplied. SIST EN 10245-1:2012
EN 10245-1:2011 (E) 10 4.2.2 Colour The characteristics shall be agreed at the time of ordering between the manufacturer, applicator and specifier/purchaser using the methods described in 4.3.2. Unless otherwise specified at the enquiry and order, the colour difference of coating material and component colour differences shall be within the following limits: ∆E:
5 max. ∆L:
1,5 max. ∆a:
3 max. ∆b:
3 max. where ∆E is the colour-difference evaluation; single number defining the total colour difference between a test specimen and its reference specimen (see EN ISO 105-A08:2002, 2.11); ∆L is the lightness-darkness difference (see EN ISO 105-A08:2002, 2.2, Note); ∆a is the redness-greenness difference (see EN ISO 105-A08:2002, 2.2, Note); ∆b is the yellowness-blueness difference (see EN ISO 105-A08:2002, 2.2, Note). 4.2.3 Apparent density The density and/or the apparent density of the powders may be agreed between the manufacturer, the applicator and the supplier and shall be expressed in g/dm3. 4.2.4 Hardness The hardness of the organic coating material may be agreed between the manufacturer, the applicator and the specifier at the time of the order.
4.2.5 Tensile strength and elongation The properties of the organic coating material when in solid form may be agreed between manufacturer, applicator and specifier at the time of the order. 4.2.6 Shelf life The shelf life requirements may be agreed between manufacturer and applicator at the time of the order. 4.2.7 The melt flow characteristics (extrusion index) May be agreed between manufacturer and applicator where extrudable organic coating material is ordered. The method of verification shall be agreed between the parties. SIST EN 10245-1:2012
EN 10245-1:2011 (E) 11 4.3 Test methods for organic coating materials as supplied by the manufacturer
4.3.1 General The tests described in this section are intended to be carried out by the manufacturer or the applicator on the coating material prior to the coating operation. Because of the difficulty of measuring some of the characteristics of coating material on powders or granules and also when these materials are applied to wire products, the tests shall be carried out on specially prepared samples. This applies in particular for the measurement of the density, the tensile strength and elongation, the hardness. The samples shall be prepared by compressing and heating a quantity of powder or granules at the melting temperature. After cooling samples shall be cut open to check for air bubbles and trapped air. If present, the sample shall be discarded and the test repeated until the sample is free from air bubbles. 4.3.2 Colour This shall be assessed either by visual comparison with an agreed standard using the method described in EN ISO 3668 or by instrumental measurements of the colour co-ordinates of a standard and a representative test piece using the method described in ISO 7724-2 and ISO 7724-3. 4.3.3 Density
4.3.3.1 Method for determining the density of organic coating material 4.3.3.1.1 General Powders, granules, pellets or moulded organic coating material shall be tested in accordance with the methods detailed in EN ISO 1183-1, -2 and -3. Because of the difficulty of measuring the density on the materials as supplied, tests shall be carried out on specially prepared samples as described in 4.3. On cooling, the pressed shape of solid plastic material shall have its volume and mass measured, in order to calculate its density. After measuring their mass the samples shall be cut open to check for air bubbles, and trapped air.
The density of some organic coating materials is affected by ageing, in such cases the parties shall agree on the time lapse for the tests to be carried out

Introduction
This European Standard for organic coatings for steel wire is a number of parts; Part 1 covering the
requirements of a general nature and applying also to coatings for which no specific requirements have been
established in the subsequent parts of this standard.
The subsequent parts of this standard deal more specifically with clearly defined coatings or groups of
coatings. These coatings may have their own particular methods of application and their individual
requirements which are specified in these parts of this standard, in other standards or in manufacturers data
sheets.
This standard is made up of the following parts:
Part 1: General Rules
Part 2: PVC coated wire
Part 3: PE coated wire
Part 4: Polyester coated wire
Part 5: Polyamide coated wire
In writing this series of standards consideration has been given to the nomenclature and transformation of
organic coating materials as applied to steel wire products. These organic coating materials may on
application to wire and by their integration into the finished wire product change their characteristics and
properties.
This standard specifies characteristics and tests not only for the organic coating but also for the coating
materials both before and after their application to steel wire and wire products. In addition it specifies the
requirements for performance levels and testing methods on organic coating material which have become an
integral and permanent part of the finished wire product. Therefore it has proven not to be practical to put all
requirements in one clause and all the tests in another one.
To aid continuity and in order to limit complexity following structure has been chosen for this standard.
Clause 4 Deals with the characteristics and testing methods of organic coating material as supplied by
the manufacturer for the purposes of its application to the wire product.
Tests described in this section are intended to be carried out by the organic coating material
manufacturer or the applicator before the coating operation.
Clause 5 relates to the characteristics and testing methods for the "organic coating" when the organic
coating material has been applied to and has become an integral part of the finished wire. Consequently
tests are intended to be in the main carried out by the coating "applicators".
Clause 6 definies the performance requirements and testing methods on the "organic coating" of the
finished wire product, and where this is not possible, tests will be carried out on "coated" panels.

1 Scope
This part of EN 10245 specifies the requirements for the characteristics and testing methods for organic
coatings made of organic coating material suitable for the application on to steel wire and wire products of
circular or other sections.
Other organic materials which are applied intentionally or otherwise such as oils, greases, waxes and
temporary finishes which do not become integral or a permanent part of the finished wire product are excluded
from this standard
This standard EN 10245 is in a number of parts, Part 1 covering the requirements of a general nature and
applies to organic coatings and coating material for which no specific requirements have been established in
the subsequent parts of EN 10245.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
organic coating
the layer of organic coating material when deposited intentionally onto the wire/wire product substrate in a
clearly specified manner. On becoming an integral part of the wire product the "organic coating" will impart
specific functional and performance characteristics. The organic coating material may be applied directly to
the surface of the steel wire or subsequent to a pre-treatment of the steel wire surface with a primary coating
which can consist of inorganic or organic materials. For the purpose of this definition the steel wire/wire
product may be coated with a non-ferrous metallic coating or not
3.2
organic coating material
a material made essentially of organic compounds capable of covering the steel wire surface after suitable
preparation
The "organic coating materials" generally contain other matter such as pigments, fillers, plasticisers, lubricants
and other additives which are specific to each organic coating material composition
The organic coating materials may be applied using a liquid solution containing organic products capable of
covering the surface with the desired organic coating material
The organic coating material may also be applied in the solid form, e.g. powder or in the form of granules. A
powder coating is generally applied by depositing the powder on the wire/wire product and then sintering by
melting the powder onto the wire product. Granules are applied to a wire by feeding them into an extruder and
extruding the "organic coating" onto the wire substrate.
Organic coating materials can be subdivided into several groups each having its own characteristic method of
application
3.2.1
thermoplastics materials
materials having the specific property of softening when heated and hardening or solidifying when cooled.
This process is reversible and allows a certain degree of recycling or reprocessing of the material
These materials include PVC, nylon, polyethylene, polypropylene and the copolymer vinyl ethylene acetate
These materials may be applied by one of the following methods: electrostatic spraying, fluidized bed or
extrusion
3.2.2
thermosetting materials
materials having the property of changing into much more infusible and insoluble product when hot
polymerized by methods such as radiation, catalysts. etc. Once polymerized and made insoluble they cannot
be remelted. These materials include polyester and epoxy coatings. These materials are typically applied by
electrostatic powder spray
3.2.3
plastisols/organosols
suspension of fine particles of inorganic materials such as resins, PVC, etc carried in an organic fluid or
solvents. After immersion or spraying, exposure to heat causes the plastisol to melt to form a solid continuous
flexible organic coating

prEN 10245-1:2008 (E)
3.2.4
paint
materials coloured with organic and sometimes inorganic components, dispersed in oils or water. They are
applied in liquid form to the surface of the wire and after air drying they form a continuous adherent film on the
wire. Application is by brush, roller or spray (electrostatic or atmospheric) or by immersion
3.2.5
varnish
generally organic materials which are transparent or coloured with an oil, resin and solvent base, which are
then air dried. Application is the same as for paints (see 3.2.4)
3.2.6
lacquer
synthetic organic transparent or coloured coating which generally dries to form a film after evaporation of the
solvent
3.3
test piece
as the definition in EN 10021
3.4
significant surface
part of the total surface over which it shall be ensured that the "organic coating" complies with the specific
requirements of the Standard
3.5
pre-treatment
operation carried out on the wire/wire products before the final application of the organic coating material
3.6
shelf life
the period which an organic coating material, securely packaged and stored according to the manufacturer's
recommendations, may be kept from the time of manufacture to the actual use by the applicator and still retain
the characteristics and properties as specified
3.7
meltflow index
rate of extrusion of molten resins through a die of specified length and diameter under prescribed conditions of
load and piston position in the barrel as the timed measurement is being made
3.8
manufacturer
the organisation which manufactures the organic coating material
3.9
applicator
the organisation which applies the organic coating material to the wire/wire product and transforms it into an
organic coating which is an integral part of the finished wire product
3.10
specifier
the organisation issuing a contract specifying the particular properties and performance requirements of a
finished wire/wire products covered with an organic coating. The specifier is usually the purchaser of the
finished wire product

4 Requirements and testing methods for the organic coating material
Many characteristics of organic coating materials prove difficult to measure. This is why a good number of
characteristics in this European Standard relate to requirements for organic coating materials as supplied by
the manufacturer. The manufacturer's data sheet may supply many of these characteristics. They shall also
give the necessary information for traceability of the materials.
4.1 Requirements
4.1.1 Composition
The manufacturer shall supply reference data for the qualification of the material. The organic coating material
shall comply with the compositional characteristics specified at the time of the order. The specifications
commonly include quantities and type of pigments, plasticizers, lubricants and other organic and inorganic
materials agreed mutually.
The manufacturer shall immediately notify the applicator of any subsequent change in the type and quantity of
the constituent parts of the composition once this has been agreed between the two parties. The manufacturer
shall also provide appropriate information for easy identification of the batches supplied.
4.1.2 Colour
The characteristics shall be agreed at the time of ordering between the manufacturer, applicator and
specifier/purchaser using the methods described in 4.2.1.
Unless otherwise specified at the enquiry and order, the colour difference of coating material and component
colour differences shall be within the following limits:
∆ E: 5 max.
∆ L: 1,5 max.
∆ a: 3 max.
∆ b: 3 max.
4.1.3 Apparent density
The density and/or the apparent density of the powders may be agreed between the manufacturer, the
3
applicator and the supplier and shall be expressed in g/dm .
4.1.4 Hardness
The hardness of the organic coating material may be agreed between the manufacturer, the applicator and
the specifier at the time of the order.
4.1.5 Tensile strength and elongation
The properties of the organic coating material when in solid form may be agreed between manufacturer,
applicator and specifier at the time of the order.
4.1.6 Shelf life
The shelf life requirements may be agreed between manufacturer and applicator at the time of the order.

oSIST prEN 10245-1:2008
prEN 10245-1:2008 (E)
4.1.7 The melt flow characteristics (extrusion index):
May be agreed between manufacturer and applicator where extrudable organic coating material is ordered.
The method of verification shall be agreed between the parties.
4.2 Test methods for organic coating materials as supplied by the manufacturer
The tests described in this section are intended to be carried out by the manufacturer or the applicator on the
coating material prior to the coating operation.
Because of the difficulty of measuring some of the characteristics of coating material on powders or granules
and also when these materials are applied to wire products, the tests shall be carried out on specially
prepared samples. This applies in particular for the measurement of the density, the tensile strength and
elongation, the hardness.
The samples shall be prepared by compressing and heating a quantity of powder or granules at the melting
temperature. After cooling samples shall be cut open to check for air bubbles and trapped air. If present, the
sample shall be discarded and the test repeated until the sample is free from air bubbles.
4.2.1 Colour
This shall be assessed either by visual comparison with an agreed standard using the method described in
EN ISO 3668 or by instrumental measurements of the colour co-ordinates of a standard and a representative
test piece using the method described in EN ISO 7724-2 and ISO 7724-3.
4.2.2 Density
4.2.2.1 Method for determining the density of organic coating material
4.2.2.1.1 General
Powders, granules, pellets or moulded organic coating material shall be tested in accordance with the
methods detailed in EN ISO 1183 Parts 1 to 3.
Because of the difficulty of measuring the density on the materials as supplied, tests shall be carried out on
specially prepared samples as described in 4.2. On cooling, the pressed shape of solid plastic material shall
have its volume and mass measured, in order to calculate its density. After measuring their mass the samples
shall be cut open to check for air bubbles, and trapped air.
The density of some organic coating materials is affected by ageing, in such cases the parties shall agree on
the time lapse for the tests to be carried out after the compressed samples have been prepared.
4.2.2.1.2 Apparent density of powders for coating
In the case of powders the apparent density shall be determined by passing the powder through a fine sieve
into a graduated vessel, which has previously been weighed, until 250 ml is reached. The graduated vessel is
3
then weighed, and the apparent density in g/dm is calculated.
4.2.2.2 Method for the determination of the density of liquid organic coating materials
Sampling shall be carried out in accordance with ISO 1512. Testing for density shall be in accordance with
EN ISO 2811 Parts 1 to 4. The density shall be determined by pouring the liquid coating material into a
graduated vessel to the 250 ml mark. Weigh the vessel and determine the weight in grams. Multiply this mass
3
by 4 and the result obtained corresponds to the density
