IMO 2010 FTP Code Part 7 - Test for vertically supported textiles and films.

The standard is used for maritime safety to assess the ignitability of vertically supported textiles and films when subjected to a gas flame similar to that of a burning match.

This test method only evaluates the ignitability of vertically supported textiles and films. To evaluate the burning behavior, the object needs to be tested in full scale with larger ignition sources.

Products and materials for maritime use is fire tested according to the International Maritime Organization (IMO) code, IMO 2010 FTP Code. The results from fire testing according to the FTP-code can be used as a basis for type approval (also called the wheel mark). Type approval is regulated in accordance with European Parliament Directive 2014/90/EU. RISE can perform the fire tests, issue the certificates and perform the production control required in order to gain the wheel mark.

The testing is performed in a draught free cabinet. The textile or film is mounted on to a steel frame and put into the test cabinet. A series of pre-tests are performed to establish which ignition scenario is the worst case in warp and weft direction respectively. This is done by applying the ignition source to the surface and the edge of the specimens for 5 and/or 15 seconds. When the worst case is established, 5 further tests are performed in both warp and weft direction.

Performance criteria are in regard to burning droplets, flame spread, damaged length and after burn time.

A test report, in Swedish or English, is delivered with the test results after testing.

Material needed for testing

• At least 20 specimens of the textile or film with the dimensions 220 mm x 170 mm. 10 specimens in the warp direction and 10 specimens in the weft direction. The warp must be clearly marked on each test specimen.

If the textile or film is treated with flame retardants it must also be tested after a washing procedure to ensure the performance of the flame retardant. This means double the amount of test specimens.

FAR/JAR Part 25- Airworthiness Standard: Transport Category Airplanes

Subpart D - Design and construction, Fire protection, §25.853, Appendix F - Part I

Aircraft Materials Fire Test Handbook, Chapter 3, Horizontal Test for Cabin, Cargo compartment and Miscellaneous materials.

The method measures the burn rate of materials in passenger and crew compartments in aircrafts. The requirements are described in Part I of Appendix F to Part 25.

To be allowed to introduce an aircraft to the market, safety requirements, including fire safety, shall be met. For the United States, aviation safety is controlled by the FAA (Federal Aviation Administration) and in Europe it is governed by the EASA (European Aviation Safety Agency). The documents with requirements are called FAR (Federal Aviation Requirements) and JAR (Joint Aviation Requirements) and are identical to each other.

The test takes place in a specified test chamber in which the specimen is mounted horizontally. The exposed surface of the material is facing down towards the flame. The material is brought against the gas flame. It is recorded how far the material burns and how long it takes for the flames to spread in the material. The result (burn rate) is expressed in mm/min.

A test report, in Swedish or English, is delivered with the test results after testing.

Material needed for testing

• 4 specimens with dimensions 51 mm x 305 mm x nominal thickness (max 13 mm)

In case of production direction in the material, specimens need to be prepared in two directions.

Who needs a DSWM?

Accurate measurements of power and related quantities is required in many situations:

• Verification of power quality calibrators and analyzers.
• Verification of power and energy reference equipment.
• In standards laboratories to ensure measurement techniques and equipment meet appropriate standards.

Complete DSWM systems are now being used at Fluke as a primary reference for the Fluke 6100A Electrical Power Standard and also at national standards laboratories such as A*STAR in Singapore and the Czech metrology institute, CMI. Our current shunts and voltage dividers are being used in more than fifteen laboratories around the world.

Characteristics

The DSWM is a primary reference for electrical power and related quantities.

• Voltage, current, power, impedance, harmonics 
• Flicker and other modulation measurements  
• 50 ppm accuracy
• 50 mV … 1000 V
• 5 mA … 100 A
• 15 Hz … 5 kHz 
• Flexible & easy to use

Background

In 1999 a co-worker of RISE published a doctoral thesis - Power measurement techniques for non-sinusoidal conditions. One result of this work was the development of a Digital Sampling Watt Meter, DSWM.

This has enabled the better treatment of harmonics when measuring electrical power and other AC quantities, as well as the establishment of an improved national reference for electrical power in Sweden.

Over the years, the DSWM has been improved and supplied with state of the art voltage dividers and coaxial current shunts of RISE-design.

Looking forward

In our modern society, electric energy and electricity network systems are of vital importance. Future development will include small scale production such as at windmills and with solar power and there is much discussion about smart grids and the next generation of cars will be hybrid vehicles with batteries which must be“fuelled” by the electricity network. As a result, electricity will increase in importance and with it the importance of traceable measurements of electrical power and energy.

The DSWM developed at RISE has proven to be versatile and is widely adopted for the emerging electricity market.

Phase-locking to the signal to be measured, highly accurate sampling devices

We deliver complete systems or parts like our high-precision, coaxial voltage dividers and current shunts.

We offer testing and certification of electricity meters according to Swedish, European and international standards.

Common rules for the entire EU apply to the control and approval of new electricity meter types according to the Measuring Instruments Directive (MID). RISE is a notified body for MID and can therefore issue approvals for the entire EU. All testing is accredited by Swedac, the official accreditation body in Sweden.

Even for electricity meters that are not regulated by the MID, electricity meter manufacturers can benefit greatly from a certificate from a reputable third-party laboratory such as RISE. Each test result is compiled in a report or certificate, which minimizes questions and objections when launching new electricity meters on the market.

We carry out testing according to all or part of the standards, including mechanical tests and EMC evaluation.

We perform accredited testing according to these standards:

• Swedish and European standards for MID: SS EN 50470-1, SS EN 50470-3. The tests according to these standards can then be the basis for approvals according to MID modules B and F from the RISE certification department.
• Swedish and European standards outside MID: SS EN 62052-11, SS EN 62053-21/22/23/24.
• International standards: IEC 62052-11, IEC 62053-21/22/23/24.

We also perform some testing and certification for requirements beyond the above standards:

• SP method 1618, for tests with 12 kV impulse voltage.

MID approvals and certificates as above, in collaboration with RISE Certification.

The National Laboratory for Length and Dimensional Metrology offers calibration of line scales.

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.

A calibration performed at a national laboratory fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

We offer calibration of line scales, from very accurate microscope scales (stage micrometers, glass scales) of a few mm in length, to workshop scales (steel rulers) up to 3000 mm.

Line scales are calibrated in a measuring machine using a microscope for reading of the scale lines and a laser interferometer to measure the distances between the lines. The finest, most accurate scales, manufactured of metal or glass are calibrated using a machine vision system, to detect the scale lines.

For less accurate scales with coarser lines, we use a measuring machine with a manual reading microscope to detect the lines. This method is applied on line scales up to 3000 mm. The zero point on these scales can be defined as the first scale line or at the edge of the scale.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.

RISE is verifying most types of sound level meters and sound analysers. 

The national laboratories are responsible for maintaining the national reference standards for each measurement quantity and spreading metrological competence and traceability to industry and society at large. The national reference standards are the highest level of traceability in Sweden.

A calibration performed at a national laboratory fulfils all typical traceability and accreditation requirements that commonly exist in industry and society at large. 

The characteristics of sound level meters are specified in the international standard IEC 61672, or for older instruments IEC 60651 and IEC 60804. Measurement procedures and tolerances to verify that the characteristics of the sound level meter are correct are also stated in these standards. Examples of characteristics which are tested: frequency response of microphone and filter, the different time weightings (Fast, Slow etc.), level linearity, overrange indication etc.

Sound level meters are divided into different classes of accuracy, where class 1 is normal for precision measurements and class 2 for simpler measurements. Approximate accuracy for a sound level meter of class 1 is 1 dB and 2 dB for class 2. However, the accuracy is dependent on the character of the sound.

Sound level meters have often an octave band analysis feature. Characteristics for this is specified in a separate standard, IEC 61260.

The calibration results are reported in a digital calibration certificate in Swedish or English which states that the calibration was performed at a national laboratory.
