What is the standard size of a wallpaper roll according to this IS code?

The standard roll is 10.05 m (± 1.5%) long and 530 mm (± 1.5%) wide, as per Clause 5.1.

How does the code differentiate between 'washable' and 'scrubbable' wall coverings?

Washability and scrubbability are defined by the number of cleaning cycles a material can withstand. For example, 'Extra-washable' must withstand 100 cycles, while 'Scrubbable' must withstand 1000 cycles (Table 1 and Annex B).

What is the minimum requirement for colour fastness to light?

All classes of wall coverings must have a colour fastness rating of not less than 3 on the 1-8 blue wool scale when tested (Table 2).

Are there fire safety requirements in this standard?

No, this standard does not cover fire safety aspects. Fire performance should be checked as per national building codes or other relevant standards for specific project requirements.

Practical Notes

Always check the batch number when purchasing multiple rolls to ensure colour and pattern consistency across a single surface.

Pay close attention to the classification (e.g., 'extra-washable', 'scrubbable') in Table 1 to select a product suitable for its intended environment, like kitchens or high-traffic areas versus bedrooms.

The standard requires markings for identification, including manufacturer, batch number, and classification, which are crucial for quality assurance on site.
