Standard DIN 10955 specifies test methods for the sensory analysis of food contact materials and articles that are intended for direct food contact. This analysis is performed according to the standard to determine the migration of odor and flavor from the packaging material into the food. By default, test is performed as Difference from Control-Test (DfC-Test) with a scoring scale. Test is also available as a triangle test for an additional cost.

Determination of the water vapor transmission rate (WVTR) according to the ASTM F1249 standard. WVTR describes the amount of water vapor that passes through a material over a set period. It is an important quality indicator in food and cosmetics packaging, as an effective moisture barrier is critical to keeping products fresh and preventing spoilage. In this WVTR test, two samples per material are measured simultaneously to ensure the reliability of the measurement. The results are expressed as g/m²/day. Please disclose the desired temperature (from 18 to 40°C) and the desired relative humidity (from 20% to 100%) when placing the order. This measurement is applicable for plastic films and sheeting materials with WVTR values between 0.005 and 2400 g/m²/day. If you wish to test finished packaging instead, check out the WVTR measurement for packages.

Determination of the oxygen transmission rate of plastic films and sheet-like materials. The test is performed on two parallel samples simultaneously. Measurement conditions (temperature and relative humidity) can be chosen according to the intended use of the material. Oxygen permeability is typically measured at 23 °C and 0% relative humidity as per standard ASTM D3985. In moist conditions, for example at 38 °C and 90% relative humidity, standard ASTM F1927 is used. Please disclose the desired temperature (from 10 °C to 38 °C) and relative humidity (either 0% or from 20% to 90%) upon ordering. This measurement is suitable for plastic films with OTR values between 0.05 to 20 000 cm³/(m² * day).

Determination of carbon, hydrogen, nitrogen, sulfur, and oxygen content of an organic sample. CHNS analysis (”LECO analysis”) is performed using a flash combustion method, where the sample is combusted under 25 kPa of O2 at an elevated temperature (1000 °C), followed by gas chromatography separation and detection using a thermal conductivity detector. Oxygen is analyzed by reduction on granulated carbon at 1480 °C, utilizing high-temperature thermal decomposition and conversion of oxygen into carbon monoxide before gas chromatography separation and detection with a thermal conductivity detector. The sample can be either solid or liquid, but water in the sample affects the results. In the case of aqueous samples, it is possible to dry the sample before analysis. The price includes two parallel measurements. The results are reported as wt-% of the initial sample. The ash, drying and dry loss measurements will increase the minimum required sample material need to 300 mg. The analysis gives the total carbon, hydrogen, nitrogen, sulfur, and oxygen content of the material, but it does not identify any chemical structures. The measurement can be combined with other methods, such as GC-MS, 1H, and 13C NMR, to perform substance structure identification. Possible element packages: O, CHNS, and CHNOS.

Overall migration (OM) into simulant E (Tenax) measures the sum of volatile and semi-volatile compounds that migrate from a food contact material into food via the gas phase. According to Regulation (EU) No 10/2011, food simulant E is assigned for materials that are intended for contact with dry foods (e.g., salt, dried spices, semolina, sugar) or which can be considered to have a dry surface (e.g. unpeeled fruits, frozen foods). Simulant E can be also used if the tested material absorbs or is otherwise not able to withstand a liquid simulant (e.g. uncoated paper, napkins, tissue paper). Due to its thermal stability, Tenax is used as a simulant for the overall migration testing of materials intended for high-temperature applications (> 100 °C) if testing with olive oil is not technically feasible. Typical instances include e.g. ovenable paperboard packaging, baking paper, cooking utensils made from polyamide, and ovenable silicone molds. The test methods intended for plastics and paper have been described in standards EN 1186-13 (method B) and EN 14338, respectively. The standard overall migration limit (OML) is either 10 mg/dm2 or 60 mg/kg, depending on the regulation. Compliance can be evaluated according to various regulations/guidelines; see Table 1 for details. Table 1. Examples of available safety references for compliance evaluation of the results. Material Regulatory or other safety reference Plastics Regulation (EU) No 10/2011 (Uncoated) paper and board Resolution CM/Res(2020)9; DGCCRF MCDA sheet n°4 (V02 – 01/01/2019) Silicone Silicones Europe guidelines; French Arrêté du 25 novembre 1992 Rubber BfR XXI Coatings, varnishes, adhesives Regulation (EU) No 10/2011

This test follows the TAPPI Test Method T559. It assesses how fluorochemicals, or other surface treatment chemicals, which can make paper both resistant to oil (organophobic) and water (hydrophobic), affect the paper's surface. These chemicals work by lowering the surface energy of the paper. The test was designed to help papermakers determine if the surface treatment has been successful. The testing process involves applying a range of numbered mixtures to the paper. The mixtures are prepared using castor oil, n-heptane, and toluene as described in the TAPPI T559 standard. These reagents differ in surface tension and viscosity, or their "aggressiveness," and are numbered from 1 (least aggressive) to 12 (most aggressive). A drop of the test liquid is dropped on the paper, and after 15 seconds the drop is wiped off. If the paper is darkened by the oil (i.e. the oil has penetrated the paper), the test is considered as failed and a lower KIT mixture is tested. The test identifies the highest numbered solution that does not leave a stain on the paper. This number is then reported as the paper's "KIT rating."
