1. INTRODUCTION

1.1 PURPOSE OF THE SPECIFICATION

The goal of this document is to create standard instructions for protection systems for bodies (DTRF

150601) and painted parts (DTRF 150608), for the whole of the ALSTOM Transport Group.

The purpose of this document is to specify the test methods to be used to determine the main

characteristics of products and the results required.

General information on the paints (physical and chemico-physical, at the time of delivery and during

application) is provided by the supplier and appears in the technical sheets in the format specific to

Alstom.

This specification is to be used:

- At the time of approval of standard generic products, and is used to support the selection of

protection systems for inclusion in the Alstom product catalogue.

- Approval is required for all exterior colors (standard colors) and any new colors under

development, and is based on tests selected from this DTRF.

- During the negotiation phase with suppliers to recommend, at the time of order, the protection

and decoration solutions required and the technical alternatives proposed by the supplier.

- In the event of non-conformity, if the technical answer proves to be impractical in the long

term.

A Homologation Committee approves the products: after validation of laboratory, model and

industrial test results and REACH authorization, the approved products are entered in DTRF

150611.

The carbody is divided into four parts: the sides and ends, the roof and ends, the under-frame and the

interior and special sensitive areas (see drawing below).

In relation to the carbody, painted parts are located: Externally (visible and non-visible), internally

(visible and non-visible), and in other specific places (sensitive areas etc.).

Appendix 1: Determination of chipping resistance

1 Purpose The goal of this method is to define the operating process that enables an estimation of the resistance of a protection system to repeated impacts. 2 Principle The test consists in projecting a known quantity of specified nuts from a specific height 3 Equipment

-- a straight tube of (38 -+ 1)mm internal diameter and height (5,000 ± 5)mm, placed vertically and topped by a receptacle under which a pull cord works a trapdoor

-- a rigid support to maintain the test piece at an inclination of (45 ± 1)° centred along the axis of the tube at (30 ± 1)mm from the base of the vertical tube

-- one kilogram of steel HM6 nuts, of low carbon steel alloy and with a hardness annealing state of 210 HV5 as per Standard A 03-154, weighed with a maximum error margin of 2 grams (replaced every 50 tests).

4 Operating Process With the coated test piece at a temperature of 18°C to 25°C, place it on the rigid support, test side face up. Pour the kilogram of nuts into the receptacle. Pull the cord to free the nuts. Examine the surface of the test piece and rate it according to Article 5. 5 Expression of results

Visually evaluate the percentage of chipped surface (examination area within a circle, diameter 38 1m, centred to cover the maximum surface area of defects) using the following rating:

Rating

S = % of chipped surface Rating S = % of chipped surface

1 0%<S<10% 6 50%-<S<60%

2 10%<S-<20% 7 60%-<S<70%

3 20%-<S-<30 % 8 70%<S<80%

4 30%-<S-<40% 9 80 %-<S-<90%

5 40%<S<50% 10 90%<S<100%

NB: For multi-layer systems, note whether the substrate is exposed or not.

Appendix 2: Bend Test over Conical Mandrel

1 Method and equipment The diameter of the mandrel is 100 mm. Place the jig (figure below) in a vice, holding it by part "A" so that bend stop "C" faces the user. Place one of the shorter sides of the test piece in notch "B" with the unpainted surface in contact with the mandrel. Bend for 3 to 5 seconds by rolling the test piece around the mandrel up to stop point "C", holding the test piece by the part furthest from notch "B". Observe the bent surface with the naked eye during the test and immediately afterwards and note any deterioration.

Appendix 3: Resistance to thermal shocks

1 Cycle of exposure to moist heat and cold The cycle requires a climatically programmable enclosed space able to meet the required temperature and humidity conditions, and to change the conditions within the given time limits. The cycle comprises the following operations:

-- in the space of t0 min, pass from room temperature to (60 ± Δθ1)°C (this operation is only carried out at the

beginning of the first cycle)

-- expose to a temperature of (60 ± Δθ1)°C and a relative humidity of at least 50% for a period of (3h ± Δt1min) -- in the space of (10 sec ± Δt2sec), pass to a temperature of (-10 ± Δθ2)°C and expose for a period of (3h ± Δt1min) -- in the space of (10 sec ± Δt2min), pass to a temperature of (60 ± Δθ1)°C

Cycle to be repeated n times

Appendix 4: Determination of behaviour under salt spray

E.1 Method Before exposure, the surface of the test piece is incised up to the support using an ELCOMETER 1538/2 0.5mm blade, as per the diagram below

(The dimensions above are given in mm to 1mm, approximate dimensions)

The test is performed continuously. At the end of the test, the test pieces are washed under running water and dried by wiping. The degree of blistering is determined according to standard NF ISO 4628 parts 2 and 3 on the upper half of the test pieces. The film on the lower right half of the test piece is eliminated by chemical pickling using a product that does not affect oxidation. The extent of the corrosion is observed on the pickled surface. The width of the corrosion on the three test pieces is measured by taking the average width of the largest areas of corrosion at intervals of 10mm all along the incision. (The dimension above is in mm 1mm)

This enables the average corrosion width to be determined across the three test pieces. The surface of the test pieces is then covered with a transparent varnish.

E.2 Expression of results: Contrary to the indications in standard NF ISO 9227, the results are expressed according to standard NF ISO 4628 parts 2 and 3 by:

- degree of blistering - extent of the corrosion - average of width of corrosion (in mm) or the delaminated area (in mm2) around the damage.
