Thermal resistance according to EN 12667

Determination of the surface-drying characteristics of paints, varnishes, and related coating materials that dry by air action or chemical reaction, according to ISO 9117-3. The method does not apply to stoving products. The test uses ballotini glass beads applied to the coating surface to assess the surface-drying state. It can be performed in two ways: as a pass/fail test determining whether the surface-dry state has been reached after a specified time, or by repeated assessment at defined intervals to establish the surface-drying time. Results are reported as the surface-drying state at the specified time (go/no go) or as the time required to reach the surface-dry state. Measurlabs can also offer the following alternative drying tests from the ISO 9117 series: through-dry state and through-dry time (ISO 9117-1), pressure test for stackability (ISO 9117-2), mechanical recorder test (ISO 9117-4), modified Bandow-Wolff test (ISO 9117-5), and print-free test (ISO 9117-6). Please ask our experts for more information and a quote.

Determination of the resistance of paint films and coating systems to condensation according to ISO 6270-1. The method is applicable to coatings on both porous substrates (wood, plaster, plasterboard) and non-porous substrates (metal) and provides an indication of performance under severe exposure conditions where continuous condensation occurs on the coating surface. Test specimens are exposed to a condensation-water atmosphere for 240 hours. Following exposure, specimens are rinsed with tap water and lightly dried with paper towels before assessment. Coating condition is evaluated according to ISO 4628-1 (general principles and rating schemes) and ISO 4628-5 (assessment of degree of flaking), covering defects such as blistering, rusting, cracking, flaking, and delamination. A photographic report is provided documenting the condition of specimens at each of the following stages: Before exposure, After chamber exposure, After rinsing with tap water, After light drying with paper towels. Results are expressed using the ISO 4628 designation scheme. The test does not yield lifetime prediction data and is not intended to simulate specific outdoor environments; results are best used for comparative ranking of coating systems or compliance with specified requirements.

Determination of methane transmission rate of plastic films and sheet-like materials with the differential pressure method (ISO 15105-1). Testing is performed on two parallel samples. Measurement temperature can be chosen from 0 °C to 200 °C with a relative humidity of 0%. Fragile samples can be measured with the equal pressure method (ISO 15105-2) for an additional fee.

Determination of the properties of high-pressure decorative laminates (HPL), i.e., sheets based on thermosetting resins, according to EN 438-2. The standard specifies test methods applicable to HPL sheets as classified in EN 438-3 (standard grades), EN 438-4 (compact laminates), EN 438-5 (flooring grades), EN 438-6 (exterior grades), EN 438-8 (design laminates), and EN 438-9 (alternative core laminates). The following properties can be determined: Dimensions and geometry: thickness, flatness, length, width, edge straightness, and squareness, Surface resistance: abrasion, micro-scratch resistance, scratching, crazing, and impact by small- and large-diameter balls, Stain and chemical resistance: resistance to domestic staining agents and chemicals, Thermal and moisture resistance: resistance to dry heat, wet heat, boiling water immersion, water vapor, wet conditions, and climatic shock, Light and UV resistance: lightfastness and resistance to artificial weathering and UV light, Formability: assessment of postformability characteristics, Dimensional stability at elevated temperature. Tests can be performed as pass/fail assessments against specified requirements or to generate quantitative performance data for product classification and comparison. Please specify the properties to be tested when requesting a quote.

Performance testing of protective paint systems for corrosion protection of steel structures according to ISO 12944-6. Results support coating selection and specification rather than predicting in-service durability. The method applies to protective paint systems on the following steel substrates: Uncoated carbon steel, Hot-dip galvanized steel (ISO 1461), Steel with thermally sprayed metallic coatings (ISO 2063-1 and ISO 2063-2). It covers environments classified C2 to C5 and Im1 to Im3 per ISO 12944-2, and does not apply to electroplated or painted steel substrates. Testing combines standardized exposure regimes selected according to the target corrosivity category, which may include water immersion (ISO 2812-2), water condensation and humidity exposure (ISO 6270-1), neutral salt spray (ISO 9227), and cyclic ageing (ISO 12944-6:2018, Annex B). After exposure, the following assessments are performed: Adhesion by pull-off (ISO 4624), Blistering, rusting, cracking, flaking, and delamination, including corrosion at a scribe (ISO 4628 series). Sample preparation follows ISO 15528 and ISO 1513. Dry-film thickness (ISO 2808) is measured and recorded for each coating. Results are reported using the ISO 4628 designation scheme for each degradation mode, and the paint system is classified by corrosivity category and durability range (e.g., C5-M medium). The test report also includes drying, curing, and conditioning details; any reference system used; results for each individual test panel; and any deviations from the specified methods.

Diesel exhaust fluid (DEF) is an additive used in diesel-powered vehicles to help the catalytic reduction of nitrous oxides. Thus, the use of AdBlue and other exhaustive fluids improves ambient air quality. DEF testing package according to ISO 22241:2019 includes the measurements listed below: Urea content (ISO 22241-2C), Density at 20 °C (EN ISO 12185) , Refractive index at 20 °C (ISO 22241-2C), Alkalinity as NH₃ (ISO 22241-2D), Biuret (ISO 22241-2E), Aldehydes (ISO 22241-2F), Insoluble matter (ISO 22241-2G), Phosphate (ISO 22241-2H), Determination of Al, Ca, Cr, Cu, Fe, K, Mg, Na, Ni, and Zn content (ISO 22241-2I).

This test is used to evaluate the color fastness of dyed or printed paper or board that is intended to come into contact with food. The applied simulants are Olive oil, 3% acetic acid, Alkaline salt solution (saliva simulant), Distilled water. Color transfer is assessed against a greyscale according to standard EN 646.

X-Ray Reflectometry (XRR) analysis is used to measure the density (g/cm3), thickness (nm), and roughness (nm) of thin films. The method is applicable to the characterization of single- or multilayered thin films, as it provides information on the thickness and density of individual layers of the sample material as well as the roughness of the interphases. Greatest accuracy for XRR thickness measurements is generally achieved for samples containing 1-150 nm thick surface layers with under 5 nm RMS roughness. Thicker films and coatings with rougher surfaces can also be characterized, but the accuracy of thickness determination decreases as the thickness and roughness of the film or film stack increase. >150 mm wafers are typically cut to fit the sample holder. Please let us know if you need testing for larger wafers that cannot be cut into pieces. The available temperature range for XRR measurements is 25-1100 °C, and crystallinity can be studied as a function of temperature. The measurements can be performed under a normal atmosphere, inert gas, or vacuum. Measurements are typically performed using one of the following instruments: Rigaku SmartLab, Panalytical X'Pert Pro MRD, Bruker D8 Discover. Please let us know if you have a preference for a specific instrument.

The burning rate of horizontally mounted materials designed to be used in vehicles and buses must be tested with the UN/ECE R118 annex 6 test before they can be approved for use. Measurlabs offers this and the other R118 tests with accreditation. In the test method, the exposed side of the test specimen is burned from underneath and the burning rate is measured and expressed in mm/min.

A dilatometer is used to determine the linear thermal expansion of a material as a function of temperature. The temperature range of the measurement is generally between 25 °C and 1,600 °C. There is also an option to perform the test in a cryogenic atmosphere, which ranges from -175 °C to 300 °C. The typical heating rate is 3 °C/min. As a result of the measurement, you will get the coefficient of thermal expansion (CTE) and the absolute change in sample length, both as a function of temperature. The testing can be performed in various atmospheres, including air, argon, CO₂, N₂, and O₂. Please contact us to get a quote. The price will depend on the testing conditions, so please specify them as precisely as possible.
