Classification and Performance Requirements for Doors Windows and Sliders — IS 18648 (2024) Testing

The IS 18648:2024 test procedure depends on the type, construction and intended application of the door, window or slider. The product is assessed against applicable performance and classification requirements, with testing performed according to the relevant clauses of the standard by a competent laboratory.

The applicable tests under IS 18648:2024 depend on the product configuration and required classification. BIS laboratory scopes identify testing against specific provisions of the standard, including clauses 7.3, 7.4.2, 7.4.3, 7.4.4 and 7.5. The exact test programme should be determined from the product specifications and intended use.

The cost of IS 18648:2024 testing varies according to the product type, number of configurations, applicable tests, sample requirements and laboratory selected. Additional charges may apply for multiple test specimens or different product configurations, so a laboratory quotation should be obtained for the specific product.

Sample requirements for IS 18648:2024 testing depend on the product type, dimensions, design and tests applicable to the particular configuration. Before submitting samples, manufacturers should provide product specifications and drawings so that the laboratory can confirm the appropriate specimen size and quantity.

Yes. IS 18648:2024 covers complete units of doors, windows and sliders manufactured from aluminium alloy as well as uPVC. Testing evaluates the applicable performance characteristics and classification requirements for the particular product configuration.

Yes. uPVC sliders fall within the scope of IS 18648:2024 when they meet the standard's specified product scope. The applicable tests and classification depend on the design, construction and intended use of the slider.

Yes. The scope of IS 18648:2024 includes complete door, window and slider units together with their constituent materials and glazing. The glazing arrangement can therefore form part of the overall product evaluation and performance assessment.

IS 18648:2024 provides a specific Indian Standard framework for classification and performance requirements for covered doors, windows and sliders. General testing may refer to individual characteristics or other standards, whereas IS 18648:2024 provides requirements for evaluating the complete covered product unit.
