• CEI 61537 (Extrait § 7.1) Each system component shall be durably and legibly marked with - the manufacturer’s or responsible vendor’s name or trade mark or identification mark - a product identification mark which may be, for example, a catalogue number, a symbol or equivalent.

When system components except cable trays land cable ladder are packaged, the product identification mark may be, as an alternative, marked on the package. Compliance is checked by inspection.

For the product marking, compliance is also checked by rubbing by hand during 15s with a piece of damp cotton cloth and again during 15s with a piece of cotton cloth soaked with petroleum spirit.

As an evidence of their compliance to standards, TOLMEGA cable trays and cable ladders are marked. For a better identification, the product code, size and finish is written in addition of the marking if applicable.

NOTICE . Basket trays : If data cables are not correctly fixed, the result can be a deformation on every transversal wire mesh, 100 mm to 100 mm.

Of course, this distortion is bad for the signal quality.

We recommend to unroll cables instead of pulling it, do no twist and do not overload.

Maximale emission, die ein Emissionsniveau Gerät nicht überschreiten darf a) The first characterisation is not recommended :

• There is no standard test report method about cable trays.

• Reducing radiation effect depends on reference, but EMC references are not stable (according to connections, installation conditions, environment conditions,…)

• So, results are not repetitive. They depend on test methods and conditions.

It could be dangerous to extrapolate on site the reduction of radiation measured in insulated room. b) Characterisation by transfer impedance is the way used by laboratories and cable manufacturers : • impedance is a intrinsic parameter of the cable trays, apart from conditions of use.

• Measurement method is well known, repetitive and suitable.

TOLMEGA uses this characterisation method.

The lowest transfer impedance level is the highest reducing effect of cable trays.

B - Description ZINC ON STEEL COATING

• PG: CONTINUOUS HOT-DIP GALVANISED WIRE

• G: HOT-DIP MILL GALVANIZED STEEL SHEET (EN 10327/ ASTM A653 / BS 2989) The galvanized steel sheet is obtained by immersing a previously-treated steel sheet in a bath of molten zinc at 450-460°C. The current grade of Z 275 NA is of a thickness of 18 µ per face, or 275 g/m2 per double face, normal zinc formation N, finishing grade A. Contrary to wide-spread belief, no corrosion is possible in sections of the metal when a galvanized metal sheet of current thickness is sheared or stamped. Iron is protected through the battery phenomenon consisting of the Iron-ZINC ELECTROLYTIC system.

• HDG: HOT-DIP GALVANIZED AFTER FABRICATION (EN ISO 1461/ ASTM A123M / BS 729) After a surface treatment, the steel is immersed in a bath of molten zinc.

This gives a zinc thickness ranging from 49 to 70 µ depending on the thickness of the metal sheet.

ISO 1461 Zinc thickness (HDG) thickness mm 3<e<6 1,5<e<3 e<1,5

(EN 10244-2) The wire is continuous hot dip galvanized (220 g of zinc/m2).

Then a wire drawing is processed in addition. For UNIFIL products, this is a very economic and high corrosion resistance proceeding.

• GM: Zn/AL coating 1) GM process is made of very thin strips of zinc and aluminium into a mineral binder. This structural passivation allows an equivalent corrosion resistance than hot-dip galvanization (saline spray test ISO 9227: 1000 H).

2) Chrome free coating according to ROHS. 3) Applications: Bolting nuts in association with HDG products.

• ZM: High corrosion resistance zinc coating ZM process is an electrolytinc zinc coating and high corrosion finish.

ZM is chrome free to ROHS. Allows an equivalent corrosion than HDG (saline spray test ISO 9227/1000 H).

Applications: all products not available for HDG process.

Appeerance: light blue bright.

• ZINC +: COATING ON EZ This special zinc protection process allows a better corrosion resistance than G or EZ (saline spray test ISO 9227: 400 H).

Appearance: silk finish. No droplets after drying.

• EZ: ELECTRO-ZINC GALVANISING (EN 12 329- EN 12 330 - NFA 91472/ ASTM B 633) Electrolytically, a zinc coating is deposited on the steel. The baths used consist of acid alkali solutions of zinc salts. The anodes are in zinc (generally to 99.99 % of purity) and the parts to coat, previously degreased and cleaned, are connected to the cathode.

After galvanizing, the parts are chromed to increase the protection.

WHITE RUST Under what conditions does white rust appear ?

Fast oxidization is needed , either under a heterogeneous film of water, or under permanent condensation (for example by differential aeration).

This fast oxidization can be local or general. It is the precipitation of basic salts of zinc Zn (OH) 2. These basics salts are powdery, not very adherent and provide no protection. However, they quickly combine with components of the surrounding air to form a protective layer of basic zinc carbonate. The basic salts formed are not very soluble in water and they accumulate in the surface patina until reaching a state of balance between their elimination in the form of soluble salts and their generation by oxidisation of the metal.

White rust has no effect on zinc coating lifetime.

OTHERS COATINGS

OTHERS MATERIALS

• EPOXY OR POLYESTER COLOURED COATINGS

• 304 L: STAINLESS STEEL X2CrMi 18-10

These coatings are generally applied on continuous galvanised steel sheet (SZ) - For greater protection, it is recommended to select a hot-dip galvanised (HDG) finish.

- For aesthetic requirements and inside buildings, an epoxy coating can be applied on mild steel XC or SZ finish.

- Outside applications : Polyester - Inside applications : Epoxy Benefits : - Save maintenance time by coloured location of the networks.

- Provides a high corrosion protection, especially in severe environments.

This two-way zinc+ coloured coating protection is the only process where the added corrosion protection properties provides more than the double of corrosion protection given separately.

Characteristics : The coating is applied by electrostatic gun-spray then stove hardened.

The heat-hardening powders offer good resistance to abrasion and shock, excellent lifetime value and requires no maintenance.

Colours : Specify the RAL reference.

(EN 10088-2 / AISI 304L) Good resistance to corrosion in natural and food atmospheres.

• 316 L: STAINLESS STEEL X2CrMiMo 17-12-2 (EN 10088-2 / AISI 304L) Especially intended for the chemical and food environments, and surface treatment. Except by written agreement, all products supplied Tolmega for stainless steel equipment always mean: - Not trimmed- Not degreased- Not cleaned, decontaminated or passivated . We can perform complementary treatment of decontamination / passivation on request.

• AG3: ALUMINIUM ALLOY 5754 (EN 573- NF EN 485 / ASTM B275 - ASTM B209) As for the stainless steels, AG3 is protected from exterior corrosion by a passive layer of alumina, which is naturally formed in the air.

Its resistance to corrosion is very good in neutral environments (4<pH<10) and also marine atmospheres. On the other hand, it is very sensitive to electrolytic corrosion. The complementary treatment of anodisation reinforces the thickness of the passive layer of aluminia. This treatment can be applied on request.(4<pH<10) and also marine atmospheres. On the other hand, it is very sensitive to electrolytic corrosion. The complementary treatment of anodisation reinforces the thickness of the passive layer of aluminia.

This treatment can be applied on request.

B - Electrolytic corrosion Electrolytic corrosion is defined as a process of accelerated corrosion resulting of an electric current between two metals coupled in an electrolytic environment .

Below the red line, the metal is being attacked.

The joined metal undergoes no galvanic corrosion but, on the contrary, enjoys an effect of galvanic protection. Electrolytic corrosion is very important when choosing the assembly bolts and certain accessories different from the cableway support.
