T/GIES 021-2024 Quality grading and "Pioneer" evaluation requirements for bathroom electric heating equipment (bathroom heater)

Scope

Scope: This document specifies the basic requirements, evaluation indicators and requirements, evaluation methods, and grade classification for the product quality and enterprise standard levels of bathroom electric heaters (bathroom heaters). This document is only applicable to single-phase rated voltages not exceeding 250V, and other rated voltages not exceeding 480V, which use PTC electric heating elements for heating and also have ventilation functions. Fan type bathroom heaters can be used for quality grading and enterprise standard level evaluation. Relevant institutions can refer to this document when conducting quality grading and enterprise standard level evaluation, "Leader" product evaluation, and related certifications. Relevant enterprises can also refer to this document when formulating enterprise standards. Main technical content: The implementation of this "Quality Grading and 'Leader' Evaluation Requirements for LED Standing Reading and Writing Lamps" will divide different grades based on multiple indicators such as general color rendering index, forced convection temperature rise, heating time, temperature rise gradient, airflow volume, and ventilation energy efficiency, providing a scientific evaluation method for this product.
