Regulations

UNE EN 1869

UNE EN 1869 has been created and approved by CEN/TC 70 Technical Committee "Manual equipments to protection against fire" reaching the national standard rank. According to CEN/CENELEC Internal Rule, the following countries are forced to adopt this European Rule: Germany, Austria, Belgium, Denmark, Spain, Finland, France, Greece, Iceland, Italy, Luxemburg, Norway, Netherlands, Portugal, United Kingdom, Sweden and Switzerland.

The specific European rule for the product, UNE-EN 1869:1997, is set in three sections that define and set the qualifications by items on the marketplace in order to guarantee the safe use of the product

    • Manufacture. The confection details are established to guarantee operativility and handling (handles, weight, flexibility and blanket's consistency as well as its electrical resistance to ensure its safe use in fires closer to electrical sources).
    • Efectivity against fire. A test method is established to guarantee the extintion efectivity. Blankets should be capable to carry, suffocate and cool a fire set hby three liters of warm edible oil.
    • Marking. Content and the form of minimal information contained by product's packaging is fixed.

Application range

This regulation especifies the minimun requirements and test methods to extintion clothing, including hoods, aprons, sleeves and spats used for users' protection during the welding operations and affine processes. This type of protection clothes are used to protect a user from small cast metal spashes, small contact periodes with fite, radiant heat produced by the welding arc and minize the chance of an electrical shoc by the accidental contact with electrical conductors with a 100 V d.c. voltage.

The regulation sets two level of protection:

    • Class 1: Protection against lower damages in welding jobs and situations that provoke lower levels of splashes and radiant heat.
    • Class 2: Protection against higher damages in welding jobs and situantions that provoke higher levels of spashes and radiant heat.

ISO 9150 Impacto de pequeñas salpicaduras

Test must be done over 10 testing sample with the size of 120 mm x 20 mm.

Testing rods composition is very importante, because it affects to measures repeatability. Composition must be according ISO 636 standards and lineal density will be (0,5 + 0,2) g/cm.

A size of the steel rod is melted, in the flame of a oxycetylene torch with a 1,2mm diameter hole. Rod is taken forward by a variable speed engine with a pulley system. Before testing, the engine speed must be adjusted in order to feed the steed rod with a 10g/min speed. All the parameters once adjusted, a test is done consisting in the proyection of iron melted drops in a point over the testing sample, vertically oriented, and the number of drops needed to heat temperature to 40ºK are measured in a temperature sensor placed behind the sample.

A minimum of three samples (230 mm x 70 mm) will be tested for each material or set of materials.

Test: A sample of fabric is submitted to a radiant heat incidental flux of 20-40 kW/m2 ± 5%. Heat passing through the sample is measured by a calorimeter placed behind the fabric and in conctact with it. Radiation must be stopped when the clometer's heat raising reaches 10ºK or after 5 minutes. Needed time must be measured in seconds, in order to produce a heating of the temperature in the calorimeter, which means the average time a person takes to feel hot due to second degree burns produced by this heating of temperature.

The test piece non-cut part is free. The dynamometer is turned on with a 100 mm/min constant speed, moving one of the clamps (mobile clamp) and the tearing must be continued until it arrives to the marked point 2,5 cm of the test piece's edge.






ISO 13937-2 Resistencia al rasgado

Five samples for the warp and five samples for the weave must be tested for each material. Test: the test piece is fixed on the clamps, with a leg on each of them. The test piece non-cut part is free. The dynamometer is turned on with a 100 mm/min constant speed, moving one of the clamps (mobile clamp) and the tearing must be continued until it arrives to the marked point 2,5 cm of the test piece's edge.

Tearing calculation: from each of the tested test pieces, the resulting graphic must be divided in four equal parts. First part must be despised and the remaining three, the two higher peaks and two lower peaks are taken. With these 12 obtained results in each testing tube a media is done.





UNE EN ISO 13772 Comportamiento al fuego | Cortinas y Cortinajes

Purpose and application field

This standard specifies the method to evaluate propagation easyness of the flame in fabrics vertically destined to the confection of curtains (simple or multicomposed fabrics as well as recovered, padded, multilayered, sandwich, etc.)

Method's principle

A detemined radiant heat flux is applied in a defined area. After an exposure periode to the flame of 30 seconds, a small flame is applied during 10 seconds to a testing cutton-fabric piece in the inferior edge. The possible flame propagation is measured through the breaking of control threads.

Operatory procedure

The test piece is placed in the testing support after putting a folded cotton fabric, with total measures of 50 mm x 20 mm and holded with a staple, in the edge where flame will be applied. In addition, a filter paper piece (150mm x 100mm) will be placed over the metalic grid under the test piece. The protective screen is retired and the sample is exposed during 30 seconds to radiant heating action. Following this, the lighter is placed with the face in the fabric's edge and the flame is kept during 10 seconds, after this time the flame is retired and the radiant heating source is turned off. Burning time is measured from the flame's application until tearing of marked threads. Also, if after combustion exist, destructed length, burning rests released or filter paper under the test piece is burnt, will be observed.

Following this, another test piece will be tested in the same direction exposing the other face to the radiator, and the same measures are listed. The effects of the exposed face with worse results will be taken into account.
  • 1. Broken marked thread.
  • 2. If the first marked thread breaks in the two test pieces, the longer burnt length one will br listed.
  • 3. If the third thread is affected, transcurred time until breaking of this thread will be listed.
  • 4. If any thread is not affected, the one will longer damage length will be listed.

Subsequently, two more test pieces will be tested with the length that gave the worst result and other test pices will be tested same way in the other direction of the fabric.
