What is the minimum thickness for the HDF door skin?

The minimum thickness for the moulded HDF skin is 2.5 mm (Clause 4.1).

What are the standard thicknesses available for these doors?

Standard door shutter thicknesses are 30, 32, 35, and 40 mm (Clause 6.1).

What is the main difference between Grade 1 and Grade 2 doors?

Grade 1 is for heavy duty use and must withstand higher performance tests (e.g., 500 slam cycles) compared to Grade 2 for normal duty (250 slam cycles), as per Table 2.

Does this standard apply to fire-rated HDF doors?

No, this is for general purpose doors. Fire-rated doors must conform to IS 3614 (Part 2) in addition to this standard's general requirements.

Practical Notes

This standard is for interior doors only and does not cover requirements for weather resistance. For exterior doors, additional specifications are necessary.

Pay close attention to the door Grade (Grade 1 for heavy duty, Grade 2 for normal duty) as it dictates the performance criteria, especially for slam tests.

Ensure the core material (solid wood, particle board, etc.) and adhesive type are correctly specified to meet project requirements for strength, fire resistance, or acoustics.
