EN12150

Route to CE marking for EN12150

Introduction

To apply the CE marking on products intended for usage in buildings is compulsary if a harmonised european standard with reference of annex ZA to the Construction Product Directive is present. This is valid for all EC memberstates and some other countries nearby related to the EC (Iceland, Lichtenstein, Swiss, Norway, Turkey). CE marking is obligatory after the coexistance period, which will end March 2007. Before this time every IGU manufacturer must prepare himself on the CE marking and hEN requirements.

Glasmandate

The rules on the level of intervention by third parties is arranged in the Glasmandate 2000/245/EC and in case an tempering plant with reference to EN12150 we do not produce fire-resistant, bullet- and/or explosion resistant tempered glass. There is involvement of the Not.Testing Body (TNO-BU T&C) for testing the product.

Section 2 : PROCES DESCRIPTION

A step-by-step summary is given of how the entire toughening process works, including the

preparation and aftercare.

1. Sorting

The glass is delivered to the toughening furnace where it is subsequently sorted according to the product. The glass is checked for holes and/or notches according to EN 12150 or own reference according the product descroption. The product definition has been based on the EN12150 directive or the company’s own regulations that are stricter or broader but with proof of suitability. A id-label with the necessary product data is applied. The FPC table [A.1 section 1 & 2, part 2] as incoming material is applied.

2. Furnace settings

The furnace settings depend on the dimensions and the product to be toughened. Possible settings:

2.1 Heating time : The time the glass remains in the furnace. The time is

expressed in seconds.

2.2 Temperatures : Heating elements are placed in the furnace, both

above and below.

These are located in 6? zones that are independently

adjustable. The glass must be heated evenly to ensure

optimum toughening quality. The adjustable temperature can vary from

620°C to 780°C.

2.3 Convection: Air is blown into the furnace from above, which prevents

the glass from bending during heating. The pressure (expressed in

bars/Pa) that blows the air into the furnace is adjustable,

depending on the product to be toughened.

2.4 Cooling : The cooling pressure (express. in bars/Pa) ensures that the glass

comes under a certain tension after heating.

The cooling pressure is adjustable depending on the product to

be toughened. Once the glass is cooled to a certain pressure,

it is considered to be toughened glass. The cooling pressure is

in principle the same above and below, though here too

settings can be made whereby the upper and underside can be

cooled with a different pressure to correct any uneven heating

and ensure the glass is properly flat.

The following table provides a guideline for setting the furnace (can also be located in the quality manual):

Thickness Dimensio n Heating time Temperatures Convectio

n Cooling

l b 1 2 3 4 5 6 Under Above Under Above 4 mm < xyx < xaz XgZ minutes XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ 19 mm < yhw < zyx dYZ minutes XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ 19 mm > yue > tgr XYg minutes XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ XYZ ……

Deviation from the above settings is permitted if necessary. This must be registered in a logbook Deviation is only allowed when the product characteristics remain unaltered in respect of the requirements of

EN12150 and any peculiarities must be stated in the product description.

3. Loading

Once the furnace has been set, the glass is loaded onto the loading tray according to product, where an

indelible mark is applied with the designation 12150. The id-label is removed. If more glass items of the

same product are loaded, these must be separated from each other by at least ?? mm, in terms of both

breadth and length. The glass is then checked to ensure that it is dry and dust-free. For silkscreen-printed

and enamelled glass the edges and underside must be checked for any residual paint. Silkscreen-printed

and enamelled glass always lie with the painted side upwards to prevent damage to the ceramic rollers. The operator can now give the signal for the glass to be rolled into the furnace.

4. Heating

Once the glass is in the furnace, it makes an oscillating movement on the rollers.

The amount of time the glass spends in the furnace depends on the product to be toughened and the

settings. Once the glass has reached the required temperature, +/- ???°c, it is automatically transferred to

the cooling zone. However, something in the way of a guideline should be included with a note that it is

permitted to deviate from the above settings if necessary. This must be registered and the product

characteristics must remain unaltered in respect of the requirements of EN12150 and any peculiarities must be stated in the product description.

5. Cooling

In the cooling zone the glass makes an oscillating movement on the rollers. The amount of time the glass

spends in the cooling zone depends on the product to be toughened. The same applies to the settings. . This must be registered in a logbook Deviation is only allowed when the product characteristics remain

unaltered in respect of the requirements of EN12150 and any peculiarities must be stated in the product

description.

Once the glass has cooled, it is transferred to the unloading tray.

6. Unloading & Product check

Once the glass arrives on the unloading tray, the id-label that was removed before loading is reapplied. The glass is taken from the unloading and its evenness is subjected to an optical check. The FPC table [A.1

section 3, part 2] is used as a reference in addition to the extra points given in the quality manual.

7. Sorting & Packing

The glass is sorted in relation to any treatment that may still be needed.

The glass is sorted per customer and placed on the glass transport ridges supplied for this purpose. Protective cork or paper is placed between each piece of glass to prevent the glass from being damaged. The glass is fastened and made ready for transportation.

B3 Sampling plan

In case of fire-resistant, bullet and/or explosion resistant glass; sampling responsibility lies at the Not.Cert.Body (TNO Certification). In the case of sampling by a Notified Body, the sampler needs to prepare and sign a record on sampling that needs to be countersigned by the manufacturer or his representative (when relevant). The record should at least include the following information:

– Manufacturer and manufacturing plant

– Place of sampling

– If necessary, stock or batch quantity (from which the samples have been taken)

– Number or quantity of samples

– Identification of the construction product in accordance with the technical specification

– Marking of the product by the manufacturer

– Marking of the samples by the sampler (when relevant)

– Where necessary, properties to be tested

– Place and date

– Signatures

– Registration number of the Notified Body

In all other cases sampling is done under responsibility of the manufacturer, whereas the following information must be in the technical file:

– Manufacturer and manufacturing plant

– Place of sampling

– Number or quantity of samples

– Identification of the construction product in accordance with the technical specification

– Marking of the product by the manufacturer

– Where necessary, properties to be tested

– Place and date

B4 ITT reports not based on historical data Insert reports of Not.Body TNO.

B5 Conformity verification by internal testing

Conformity verifications by Manufacturer own laboratory (e.g. material exchange, equivalence testing etc.). Instead of performing any all initial type testing by external body, the manufacturer may make use of conformity verifications by internal testing if it can be traced back to the ITT done externally. The basis of this evaluation can be:

?generally accepted and/or conventional and/or standardised values, in the Clause 2 referenced standards, or in publications that are referred to in these standards;

?standardised calculation methods and recognised calculation methods in Clause 2 referenced standards, or in publications that are referred to in these standards;

?where components are used whose characteristics have already been determined, by the component manufacturer, on the basis of conformity with other product standards, these

characteristics need not be reassessed providing they remain unchanged by the manufacturing

process; testing at can be required to confirm that the manufacturing process has not

influenced the results negatively. You shall include the released internal verifications in this

chapter of the technical file.
