FAQ's
❓ Frequently Asked Questions —
Drying & Heating Chambers
What is a drying and heating chamber used for in packaging testing?
A drying and heating chamber provides precise, uniform temperature control for conditioning, drying, ageing, and heat-resistance testing of packaging materials. It prepares samples before tensile, seal strength, and barrier property testing, in compliance with ASTM D618 for conditioning plastics and ISO 2233 for conditioning flexible packaging materials, paper, and board before mechanical testing.
What is the difference between natural convection and forced convection drying ovens?
Natural convection ovens like BINDER M115 use passive airflow, ideal for lightweight or dust-sensitive packaging samples. Forced convection ovens like BINDER FD 56 and ED 56 use a motorised fan for faster, more uniform heating. ASTM E145 classifies both types and defines performance and uniformity specifications for gravity-convection and forced-ventilation laboratory ovens.
When should a vacuum drying oven be used instead of a standard heating chamber?
A vacuum drying oven like BINDER VD 56 dries samples at low pressure and lower temperatures, preventing oxidation and thermal degradation. It is recommended for heat-sensitive packaging films, hygroscopic pharmaceutical powders, and moisture-sensitive adhesives where standard oven temperatures per ASTM D618 or ISO 291 would alter the material structure or chemical composition of the sample.
Which ASTM standards apply to drying and heating chambers used in packaging testing?
Key ASTM standards include ASTM E145 for gravity-convection and forced-ventilation oven specifications, ASTM D618 for conditioning plastics before testing, ASTM D4332 for conditioning packaging containers and flexible pouches before testing, and ASTM F1980 for accelerated ageing of sterile barrier and packaging systems to determine shelf life and expiry date validation.
Which ISO standards govern heating chambers used for packaging material conditioning?
Relevant ISO standards include ISO 291 for standard atmospheres for conditioning and testing plastics, ISO 2233 for conditioning flexible packaging materials, paper, and board before testing, ISO 188 for accelerated ageing and heat resistance testing of rubber-based packaging materials, and IEC 60068-2-2 for dry heat environmental simulation testing of packaging components and materials.
What is BINDER APT.line™ technology and how does it benefit packaging laboratories?
BINDER APT.line™ is a preheating chamber system that warms incoming fresh air before it enters the main working space. This prevents cold air intrusion during door openings and maintains exceptional temperature uniformity — essential for reproducible conditioning results per ASTM D618 and ISO 2233 when testing packaging films, laminates, adhesive bonds, and heat-sensitive flexible packaging materials.
How must packaging samples be conditioned before mechanical testing in a heating chamber?
Per ASTM D4332 and ISO 2233, packaging samples must be conditioned at a defined temperature and relative humidity for a specified minimum period before any mechanical testing. Forced-convection ovens ensure uniform heat distribution across all samples, eliminating moisture variability and ensuring that tensile strength, elongation, and seal integrity test results are accurate and reproducible.
Can drying ovens be used for accelerated ageing of packaging materials to determine shelf life?
Yes. BINDER FD 56 and ED 56 forced-convection ovens are widely used for accelerated thermal ageing of flexible films, laminates, adhesives, and sterile barrier packaging systems. Testing follows ASTM F1980, which uses elevated temperature ageing to predict long-term packaging performance and establish expiry dates for pharmaceutical and medical device packaging without waiting for full real-time ageing data.
What temperature range and uniformity do BINDER heating chambers provide for packaging testing?
BINDER heating chambers offer working temperature ranges from ambient up to 300°C depending on the model. Forced-convection models FD 56 and ED 56 deliver temperature uniformity within ±0.5°C to ±1°C throughout the working space. This precision meets ASTM E145 oven uniformity requirements and is essential for reproducible accelerated ageing per ASTM F1980 and conditioning per ASTM D618.
What safety and calibration standards apply to BINDER laboratory drying and heating chambers?
DIN 12880 governs safety requirements for electrically heated laboratory drying ovens, covering overtemperature protection, construction, and electrical safety. For calibration, chambers must meet ISO 17025 traceability requirements. All BINDER ovens include independent overtemperature protection and are designed in full compliance with DIN 12880, ensuring safe and reliable operation in packaging, pharmaceutical, and industrial testing laboratories.
