Packaging & Storage Guidelines (General Practice)

• Protection from Moisture: Doors must be stored in dry, well-ventilated areas to prevent swelling or warping.
• Stacking: Store flat on level surfaces; avoid direct contact with ground by using wooden battens or pallets.
• Wrapping: Use waterproof covers or shrink-wrap to protect against dust and moisture.
• Handling: Avoid impact or excessive load to prevent damage to skins and core.
• Labeling: Include size, type, grade, and certification marks as per IS 2191 requirements.

Dimensions Reference (Clause 3.1, Table 2)

*Note: Thickness as per nearest higher modular size.

Certification Marking (Clause 10.2.1)

• Use of BIS Standard Mark is governed by BIS Act 1986.
