HK toploading salt spray chamber for DIN EN ISO 9227 NSS tests – reliable salt spray testing in durable polypropylene test chambers for simple to complex corrosion testing. Corrosion testing device Toploading Our HK series Top-loading systems of the HK series are loaded from above and are particularly suitable for test items with higher weight, larger volume, or irregular geometry. The vertical loading allows for ergonomic and safe insertion of test pieces, often with the aid of cranes or lifting equipment. Advantages of toploading systems: simple and safe loading of heavy or bulky test specimens optimal use of space in the test room robust design for industrial applications High flexibility for different test specimen dimensions Minimal space required in front of the unit, as no side door is needed. Toploading systems are therefore particularly suitable for demanding testing tasks in corrosion and environmental simulation.

Our portfolio SODIUM CHLORIDE Why are corrosion testing systems and salt spray chambers needed? Many products and their materials are freely exposed to today's environmental influences. Since product quality assurance and reproduction play an increasingly important role, very high demands must also be placed on testing systems. To accelerate the corrosion process, so-called corrosion testing systems are used. These systems can depict the progression of corrosion in fast motion using various methods.

FAQs about our corrosion testing systems – answers about testing equipment, NSS tests, environmental simulation, service, and technical solutions for industry and research. Frequently asked questions about corrosion testing systems Selecting a suitable corrosion testing system requires a fundamental understanding of the terminology, test types, and application areas used. Different materials, test requirements, and standards each place specific demands on the equipment employed. This FAQ is aimed at users and decision-makers who want to gain an overview and better understand the interrelationships. The terms and principles explained here are intended to help clearly define requirements, classify differences between testing systems, and select the appropriate product for the respective application. Decision aid: Selecting the right corrosion testing equipment 1. Standards & Testing Requirements Which standard(s) do I have to meet? e.g. B. DIN EN ISO 9227 (NSS/AASS/CASS), VDA, ASTM, OEM specifications What types of tests do I need? Salt spray, condensation, fluctuating climate, cyclical testing, special tests How reproducible and compliant with standards must the results be (auditability)? 2. Test Item & Capacity Which components are being tested? Size, weight, geometry, material How many samples can be processed simultaneously (number of samples / throughput)? How often is testing performed (occasionally, regularly, as part of a series)? 3. Plant size & modularity What chamber size makes sense – today and in the future? Can the system be expanded or converted (e.g., from NSS to cyclic)? Does the system fit in the available space (door width, ceiling height, installation location)? 4. Operation & Automation How easy is it to use in everyday life? Are there automated programs, recipe management, and user rights? Documentation & data export (e.g. for quality assurance, audits, customer reports)? 5. Quality, reliability & maintenance What materials are used (corrosion resistance of the system itself)? How maintenance-intensive is the system? Calibration, spare parts, long-term availability? 6. Service & Support Is there fast service and competent contact persons? Response times, maintenance contracts, training? Manufacturer experience specifically in the field of corrosion testing? 7. Costs & Efficiency Investment costs vs. scope of services Operating costs (media consumption, energy, maintenance) Lifespan and Total Cost of Ownership (TCO) In short: Standard → Test item → Capacity → Future-proofing → Operation → Service → Costs
