Applicable Standards and Test Purpose
SASO 1858 Test Projects
This electric water heater test laboratory configuration was developed for SASO 1858 electric water heater test projects involving household storage-type electric water heaters.
Because standards and national market requirements may be revised, the required standard number, edition, destination market, and test items should be confirmed before the final technical configuration is approved.
IEC 60379 Performance Measurement Reference
IEC 60379:2023 specifies methods for measuring the performance of electric storage water heaters for household and similar purposes. Applicable performance measurement functions can be reviewed according to the confirmed project scope.
IEC 60379 addresses performance measurement rather than electrical appliance safety. Storage water heater safety testing should be considered separately according to the applicable IEC 60335 requirements.
How the Six-Station Electric Water Heater Test Laboratory Works
Test Environment Conditioning
Temperature and humidity are adjusted within the configured operating range using refrigeration, heating, humidification, and air-circulation functions.
Water Preparation
The 2000 L stainless steel tank stores and stirs the test water, with a configured water temperature range of 10°C to 35°C.
Sample Installation
Up to six electric storage water heaters are installed at dedicated test positions arranged in two rows with three stations per row.
Electrical Supply Control
The samples are connected to the inverter power system to establish defined voltage and frequency conditions within the equipment range.
Temperature and Flow Measurement
Configured channels monitor ambient conditions, mixed-water tank temperature, inlet/outlet water temperature, and water flow.
Data Acquisition and Review
Measurement signals are centrally recorded for storage, export, review, statistics, analysis, and printing, with a configurable 5–60 second sampling period.
Laboratory System Architecture
Controlled Test Environment System
The environmental control system provides adjustable temperature and humidity conditions for water heater performance testing. The referenced design includes water-cooled refrigeration, heating protection, automatic defrost, stainless steel humidification components, and automatic water-level protection.
Constant-Temperature Water Supply System
The 2000 L 304 stainless steel tank provides water storage and stirring for conditioned water preparation. The final water supply, pressure, drainage, and connection arrangement should be reviewed against the customer’s site conditions and required test procedure.

Why Controlled Water and Environmental Conditions Matter
Electric storage water heater performance can be influenced by inlet water temperature, ambient conditions, water flow, and electrical operating conditions.
For this reason, the test environment, water preparation system, power supply, and measurement channels need to operate under defined conditions throughout the selected test procedure. The KINGPO laboratory integrates these functions around six dedicated test positions to support a more controlled and organized test workflow.
Six-Station Test Capacity for Laboratory Workflows
The laboratory provides six dedicated test positions arranged in two rows. This configuration allows manufacturer and laboratory teams to organize multiple water heater samples or scheduled test projects within one dedicated test system.
Actual simultaneous test operation depends on the selected procedure, utility capacity, measuring channel arrangement, and laboratory test plan. The six-station specification represents the physical sample capacity of this laboratory configuration.
Typical Test Objects
The laboratory is intended mainly for household electric storage water heaters within the confirmed project scope. Typical SASO 1858-related projects may involve household storage-closed type electric water heaters.
The exact sample type, rated storage capacity, dimensions, weight, and electrical characteristics should be reviewed before system configuration. Instantaneous, heat-pump, solar, or industrial water heating products should not be assumed to use the same test configuration without technical review.
Typical Laboratory Use Cases
Manufacturer R&D Laboratories
For controlled performance measurement and comparison of electric storage water heater samples during product development.
Internal Performance Verification
For internal product evaluation and engineering verification with continuous recording of configured temperature, flow, and operating data.
Quality and Engineering Laboratories
For teams that require a dedicated workflow combining environmental conditioning, water preparation, sample installation, and data acquisition.
Third-Party Test Projects
For electric storage water heater test projects within the confirmed standard, measurement, documentation, and calibration scope.
