Qualitätsmanagement

Quality management across the product lifecycle

LEST combines production control with precision testing equipment to support consistent steam-cleaner manufacturing. Quality work begins with product requirements and continues through component inspection, assembly control, functional checks and shipment preparation.

Control focus

• Electrical and heating-system checks
• Temperature-control and steam-output verification
• Water-tank, hose, seal and accessory-fit inspection
• Safety-function and operating-control checks
• Appearance, packaging and configuration confirmation

Certification support

The 2026 LEST catalog presents CE, UL, RoHS, FCC and ETL certification marks. Certification scope can differ by model, voltage, component configuration and destination market. Please contact LEST for the applicable certificate and report before placing an order or making a compliance claim.
