Atlas Xenotest 440 - Compact weathering test instrument with high irradiance

Xenotest 440 considerably reduces weathering tests with two xenon lamps

The Xenotest 440 weathering test instrument from Atlas Material Testing Technology enables more efficient weathering testing thanks to its features. With two xenon arc lamps and the patented XenoLogic technology, samples can be exposed to stronger radiation in the Xenotest 440. At the same time the test chamber offers more test space for material samples and therefore enables a greater number of tests in a shorter time. Xenotest 440 is used in branches where coatings, textiles, plastics or automotive components are tested for their weathering resistance.

Products such as coatings or textiles are exposed to many different climatic conditions during their product lives which can damage the materials and surfaces. Manufacturers want to prevent this and therefore test the material samples of the products for their weather resistance - in weathering test instruments. Atlas Material Testing Technology, a world leading company in material testing, offers a wide range of advanced and sophisticated instruments. These range from small desktop units such as the SUNTEST and medium-sized all-rounders such as the Xenotest series to the walk-in solar climatic chamber, used for testing complete modules. During weathering tests, material samples are exposed to radiation and humidity to be able to exactly determine possible changes to the surface or material in a short time. Test processes which can otherwise last for years produce accurate results within days, weeks or months. To increase the efficiency of these tests, Atlas now offers with the air-cooled xenon weathering test instrument Xenotest 440 an additional second lamp in connection with the innovative XenoLogic technology, which consider-ably reduces the test time and at the same time reduces maintenance and running costs.

Quality and product features
The Xenotest 440 weathering test instrument is equipped with two xenon arc lamps and, because of its high radiation power which is equivalent to the strength of two suns, it is able to significantly reduce the process time of standardized test processes. Together, the 2,200 Watt lamps achieve an irradiance of up to 120 W/m2 and therefore double the sun's radiation on the earth's surface. During the test process the patented XenoLogic lamp technology intelligently controls the use of the two lamps: If radiation only takes place at half the power, the XenoLogic algorithm controls the lighting duration of the alternately used lamps to ensure optimum utilization. In parallel operation the technology synchronizes the radiation power of both lamps and ensures reduced and even utilization. This prolongs the life by up to 30 per cent or up to 4,000 hours under optimum conditions and the lamps need to be changed less frequently. The calibration intervals are also prolonged, leading to shorter downtimes and higher productivity.

The ultrasound humidification system of the Xenotest 440 saves water thanks to state-of-the-art technology and only requires three liters of water per day to produce humidity under ISO 105-B02 test conditions during operation. With the connected, manually or auto-matically fillable 60 liter water reservoir, a continuous test operation of up to three weeks is guaranteed. At the same time the design of the device and the humidifier enable an optimum air flow within the test chamber and twice the uniformity in the distribution of temperature and humidity as is often requested in international standards. In addition, the samples can also be exposed to rain by a spray function. To check the influences on the materials, the Xenosensiv sensor in the sample rack enables the temperature and radiation to be controlled during weathering tests. With further features such as the full-color TFT touchscreen with several available menu languages, ten programmable memory places for recurrent tests and the online monitoring, Xenotest 440 considerably simplifies test operation.

Areas of application
The Xenotest 440 weathering test instrument fulfills many of the com-mon worldwide material test standards. The large test chamber and the sample holders offer a very large test area and meet the requirements of different industries: from 38 narrow test positions for textile samples and 22 wide test positions for materials from automobile equipment to eleven long test positions for plastic samples. For the different demands of the textile, automotive or plastic industries, Atlas has put together accessory kits which also include standard-conform filters in addition to sample holders and masks.

Atlas weathering sites - ISO-accredited and in all important benchmark climatezones

Automobiles, windows or plastic chairs – many objects of daily use must resist weathering stresses daily and should still have a long, trouble-free life. A challenge for almost every product and producer. Atlas Material Testing Technology therefore offers weathering tests which meet the highest demands. The accredittation of two Atlas sites in France and India now once more demonstrates the wide range of weathering tests.

Dashboards, spectacle frames, garden furniture or window frames: All of these are constantly exposed to sun, rain or snow - with sometimes undesirable consequences. Paints and varnishes can fade, flake or the products can lose their original shape. Natural factors of influence such as UV radiation, heat or humidity can attack the surface of products or even influence their function. Therefore manufacturers have prototypes tested during product development to see how they stand up to weathering conditions. "We test almost everything under the sun, from the nail varnish bottle to the complete automobile – of course in every desired climate zone", says Siegfried Roessner, expert for natural weathering testing at Atlas Material Testing Technology, the worldwide pioneer for weathering tests and technologies.

ISO 17025 accreditation for maximum process quality
Atlas has 23 weathering test sites and therefore covers all benchmark climate zones. "Weathering tests can last days, months or even several years, depending on the product," Roessner explains. This applies independently of the climate zones. It is decisive what lifetime the company has planned for the product. With Sanary-sur-Mer in the South of France for the Mediterranean climate as well as Chennai in India for the sub-tropical climate, two weathering test sites of Atlas have now been accredited. The high precision of the test methods is very important here. "We have been working according to prescribed methods for many years. Now we have also received the official confirmation for these two sites," Roessner adds.

With the ISO 17025 accreditation the structure, process and result quality of the test methods has now been classified as permanently reliable and of high quality – and consistent quality in the compliance with management specifications and prescribed rules of conduct have been certified. The range of test methods includes a large number of international industrial standards. Varnishes, for example, must pass the resistance test of the American Material Testing Association ASTM, plastic tubes must fulfill the ISO stability regulations and paints may only change minimally in accordance with the applicable DIN standard.

The accreditation also certifies the extended competence for professional assessment of processes in addition to the standards of weathering tests. The test processes can therefore be monitored, assessed and optimized by Atlas Quality Managers. Atlas is thus the only company that offers accredited weathering tests in all benchmark climate zones.

ISO, DIN, ASTM certification and benchmark climate zones
Weathering tests run highly efficiently according to exactly defined processes or accredited procedures. In order to create a constant test situation with maximum stress, the material samples, in the size and shape desired by the manufacturer, are usually mounted on special racks which are set at a defined angle to the sun so that the samples receive the greatest possible exposure to the sun's radiation depending on their final application and location. For authentic simulation of the final application it is also possible to place a plate behind the materials or to expose them to radiation in an enclosed box.

The chemical components in paints, varnishes or plastics react very differently to natural factors of influence and the constellations in which they occur. "Every climate zone logically has totally different conditions. In Chennai, India the heat together with the humidity naturally has a different effect on the materials than in Sanary-sur-Mer in France where we are currently testing many window profiles from European manufacturers in a Mediterranean climate," says Atlas expert Siegfried Roessner. Reliable test results therefore depend also on the choice of suitable weathering conditions. The three benchmark climate zones are: Mediterranean, sub-tropical or desert environment. The results of the test processes show whether the product materials satisfy international standards such as ISO, ASTM or DIN.

Direct weathering and "black box exposure"  
The methods of static weathering testing are used at the Atlas sites in Chennai and Sanary-sur-Mer: Materials are exposed to natural influences in direct weathering – as material samples or as finished end products such as automobiles or housing building components. "Black box exposure" is also possible at both sites. This simulates the conditions that prevail in an automobile.

Atlas, as a world leading weathering expert, also has test sites at which the weather resistance of products can be tested in the shortest possible time by accelerated test methods. The site in Arizona, USA, is particularly suitable for this because there the amount of direct sunlight that hits the earth is very high. In addition to natural weathering, Atlas also offers, a wide range of instruments for accelerated weathering. Atlas also has its own laboratories for weathering tests and calibrations measurement devices. Services such as comprehensive consulting on weathering tests and other services such as testing photovoltaic cells round off the portfolio.

Numerous accreditations and certifications of international standards institutes are evidence of the highest possible quality of the test processes. Siegfried Roessner: "Thanks to the accreditation of the two sites in Sanary-sur-Mer and Chennai we are expecting even more demand for product tests there. Natural weathering is an increasingly important topic for product launching especially on the varied Indian market."
