Storage test/accelerated ageing in lab drying oven or refrigerator (controlled temperature)
Storage tests with or without filling good for estimating the long-term stability of materials and packages. The storage tests, depending on the requirements, could be carried out in lab drying oven (convection), refrigerator, explosion-protected heating chamber (e. g. solvent-based media, T1 - T3 max. 105 °C; T 4 max. 70 °C), climate chamber (humidity and temperature controlled, temperature and humidity cycles possible). Please select the appropriate method to avoid unnecessary costs.
Tests according to this method serve to accelerate the estimation of material ageing, e.g. also with regard to resistance to chemicals, foodstuffs or other filling materials for long-term applications. This is an assessment of purely technical aspects. For the assessment of food law conformity, please refer to the relevant legal regulations. For initial sampling, we strongly recommend parallel testing under real storage conditions to validate the validity of accelerated ageing tests.
To prepare an offer, we need the following details/information:
What type of packaging is to be tested (size, filling volume)?
How many packages are to be stored?
Are the packages empty or do they have to be emptied before testing?
What kind of filling material is involved (CAS No./Safety Data Sheet)?
How long should the packages be stored?
Under which ambient conditions should the packages be stored (temperature, controlled relative humidity)?
Ageing test for testing the laminate film resistance to various media, e.g. according to DIN 55531/ TL 8353 - without humidity control Test for accelerated estimation of the resistance of bags made of laminated films to various media such as ASTM oil no. 3, water, etc. without taking into account the influence of ambient humidity.
Accelerated ageing at elevated temperature without humidity control Test for accelerated estimation of ageing processes of plastic materials or filled packages without considering the influence of ambient humidity.
