Learn about the mandatory BIS certification for block boards under IS 1659:2004, enforced by the latest Quality Control Order from the Government of India. Understand key testing parameters, compliance requirements, and deadlines. See how Standphill India supports manufacturers in meeting BIS standards efficiently and on time.

In the world of construction and interior design, the quality of materials plays a direct role in how durable, safe, and visually appealing the end result will be. Among the many materials used, block boards stand out for their versatility, strength, and adaptability in a range of applications—from furniture to paneling, partitions, and ceilings.

To ensure consistency in quality and to protect consumer interests, the Bureau of Indian Standards (BIS) developed a comprehensive specification for block boards, known as IS 1659:2004. With a recent government mandate making BIS certification compulsory, manufacturers must now align with these requirements to continue accessing the Indian market.

In this article, we’ll break down the essentials of IS 1659, the certification process, and how Standphill India supports manufacturers in meeting these critical standards.

Why BIS Certification for Block Boards Matters

Block boards are engineered wood products made by sandwiching softwood strips between veneers. Their structural stability and resistance to warping make them ideal for load-bearing furniture and interior décor.

However, inconsistencies in materials and manufacturing methods can lead to products that degrade quickly or pose safety risks. To address this, BIS introduced IS 1659:2004, a quality standard that specifies the materials, construction, and performance parameters for block boards.

With the Government of India’s Quality Control Order (QCO) issued on 12 March 2024, BIS certification has become mandatory for all block boards—whether manufactured domestically or imported. From 11 February 2025, only certified products bearing the ISI mark can be legally sold in the Indian market.

What IS 1659:2004 Covers

The standard applies to both commercial and decorative block boards and categorizes them into two main grades:

BWP (Boiling Water Proof): Suitable for high-humidity and outdoor environments.

MR (Moisture Resistant): Ideal for indoor use with moderate exposure to moisture.

IS 1659 outlines detailed requirements for:

Core construction and adhesive types

Quality and thickness of veneers

Dimensional accuracy and tolerances

Preservative treatments

Physical strength and resistance properties

By adhering to this standard, manufacturers can ensure that their products are fit for purpose, long-lasting, and safe.

Key Tests Required for Certification

To be certified under IS 1659:2004, block boards must pass a series of technical tests conducted in BIS-recognized laboratories. These include:

Adhesive quality testing

Core construction and bonding strength

Veneer face and cross band assessments

Dimensional accuracy and tolerance checks

Humidity-induced expansion tests

Water resistance evaluation (for BWP)

Adhesion of plies

Mycological test (fungal resistance)

Modulus of Rupture (MOR) and Modulus of Elasticity (MOE)

Spot test for surface bonding

These tests are crucial to assess the mechanical performance and durability of the boards under real-world conditions.

Certification Process: Step-by-Step

To obtain BIS certification under Scheme 1, Schedule 2 of the Product Certification Scheme, manufacturers must follow this process:

Submit Application: Complete the official BIS application with product details and manufacturing site information.

Product Testing: Send product samples to a BIS-recognized lab for evaluation.

Factory Inspection: BIS officials conduct an on-site audit of the manufacturing process and quality control system.

Documentation Review: Ensure all technical documents, test reports, and compliance records are complete and accurate.

License Granting: If all requirements are met, BIS issues a license and authorizes the use of the ISI mark on certified products.
