General pot inspection service

General Pot Inspection Service for Global Kitchenware Compliance

As an ISO/IEC 17025 accredited laboratory, we deliver a comprehensive general pot inspection service that verifies the mechanical strength, thermal performance, coating durability, food contact safety, and long-term reliability of cooking pots and saucepans. Our general pot inspection service supports manufacturers and exporters of stainless steel, aluminum, cast iron, and non-stick cookware who must demonstrate conformity to ISO 4531, EN 12983, ASTM F1568, and regional food contact and kitchenware regulations across the European Union, North America, the Middle East, and Asia. Every test is performed under our CNAS-accredited quality system, producing reports accepted by notified bodies, brand owners, and procurement teams worldwide.

• Custom-designed and OEM general pot products — for specific brand and performance requirements

Mechanical and Physical Performance Testing for General Pots

• Tensile strength and elongation of handle and body materials per ISO 6892-1 and ASTM E8 — specimens are extracted from the pot body, lid, and handle to measure the ultimate tensile strength and ductility, ensuring the cookware withstands lifting, stirring, and accidental drops without cracking or breaking.
• Hardness testing by Vickers, Brinell, and Rockwell methods per ISO 6507-1 and ISO 6506-1 — the hardness of the pot base, sidewall, and any hardened surface is measured to verify the specified material condition and resistance to scratching and denting.
• Impact resistance and drop testing per ISO 6603-2 and customer protocols — the pot is dropped from defined heights onto a hard surface and inspected for deformation, coating damage, and handle detachment, simulating kitchen accidents and rough handling.
• Handle attachment strength and fatigue testing per EN 12983 and ASTM F1568 — the force required to pull or twist the handle from the pot body is measured, and the handle is cycled through repeated loading to verify long-term durability and resistance to loosening.
• Base flatness and thermal contact verification per ASTM F1568 — the flatness of the pot bottom is measured using a calibrated straightedge and feeler gauges to ensure optimal contact with the cooking surface and even heat distribution.
• Lid fit and closure function testing per customer specifications — the lid is repeatedly opened and closed to verify smooth operation, secure fit, and resistance to warping or misalignment during use.

Coating and Surface Quality Inspection for General Pots

• Non-stick coating adhesion and peel strength per ASTM D3359 and ISO 2409 — the bond between the non-stick coating and the pot substrate is tested by cross-cut tape peel and pull-off methods, ensuring the coating remains firmly attached under cooking, cleaning, and metal utensil contact.
• Coating thickness and uniformity measurement per ISO 2178 and ASTM B487 — the dry film thickness of PTFE, ceramic, or enamel coatings is measured at multiple points to verify uniform coverage and the specified minimum thickness for durability and release performance.
• Abrasion and scratch resistance of non-stick surfaces per ASTM D4060 and ISO 15184 — the coated surface is subjected to controlled abrasive wear and pencil scratch testing to rank the coating's resistance to metal spatulas, cleaning pads, and everyday kitchen use.
• Resistance to thermal shock and coating crazing per ASTM C149 and ISO 4531 — the pot is rapidly heated and quenched to verify the coating and substrate withstand thermal expansion and contraction without cracking, blistering, or delamination.
• Corrosion resistance of metallic surfaces per ISO 9227 and ASTM B117 — the pot body, lid, and handle are exposed to salt fog to evaluate pitting, rust, and corrosion product formation in humid and coastal kitchen environments.
• Visual defect inspection under D65 illumination — systematic examination for pinholes, bubbles, streaks, and surface contamination against agreed acceptance criteria and master reference samples.

Thermal Performance and Heat Resistance Testing for General Pots

• Heat distribution and hot spot evaluation per ASTM F1568 and internal protocols — thermal imaging is used to map the temperature distribution across the pot base during heating, identifying any hot spots or uneven heat transfer that would cause food burning or sticking.
• Thermal shock resistance per ISO 4531 and ASTM C149 — the pot is heated to a defined high temperature and then rapidly cooled, and the body, coating, and handle are inspected for cracking, warping, or loss of function.
• Maximum service temperature and oven safety verification per customer specifications — the complete pot, including lid and handle, is exposed to the maximum rated oven temperature to verify the materials and coatings withstand the heat without degradation or release of harmful fumes.
• Thermal conductivity of the pot base material per ASTM E1461 and ISO 22007-4 — the thermal diffusivity and conductivity of the base material are measured to verify efficient heat transfer and energy savings during cooking.
• Heat retention and cool-down characteristics per internal protocols — the pot is heated to a defined temperature and the cooling curve is recorded to evaluate heat retention for serving and slow-cooking performance.
• Resistance to prolonged cooking and high-temperature aging per ASTM D573 — the pot is aged at elevated temperatures and the retained mechanical properties and coating performance are measured to predict long-term durability.

Food Contact Safety and Chemical Compliance for General Pots

• Overall migration in food simulants per EU Regulation 10/2011 and FDA 21 CFR — the pot is tested with aqueous, acidic, alcoholic, and fatty food simulants under the intended use conditions, and the total extractable mass is measured to verify compliance with the overall migration limit.
• Specific migration of heavy metals per ISO 4531 and EN 12983 — the release of lead, cadmium, chromium, nickel, and other toxic metals from the pot surface and any coatings is quantified to ensure it remains below the regulatory limits for food contact materials.
• Perfluorinated compound and PFAS screening per internal validated protocols — for non-stick coated pots, the presence of PFOA, PFOS, and other restricted perfluorinated substances is screened to verify compliance with global chemical safety regulations.
• Formaldehyde and volatile organic compound emission per ISO 16000-3 — chamber testing verifies that the pot and its coatings do not release harmful VOCs or formaldehyde during cooking or storage.
• Color migration and staining evaluation per GB 31604.7 and internal methods — colored pots and coated surfaces are tested to ensure pigments do not bleed into food or food simulants, maintaining both safety and visual quality.
• Heavy metals in packaging per EU Directive 94/62/62 — verification that lead, cadmium, mercury, and hexavalent chromium sum concentration in the packaging is below the 100 ppm regulatory limit.
