BIS Certification for Pressed Ceramic Tiles IS 15622:2017

To ensure quality, safety, and uniformity across the industry, the Bureau of Indian Standards (BIS) mandates certification for pressed ceramic tiles under IS 15622:2017. Manufacturers and importers must comply with this standard to legally sell or distribute their products in the Indian market.

Let’s explore what BIS certification entails for pressed ceramic tiles and why it’s essential for manufacturers and consumers alike.

What Are Pressed Ceramic Tiles?

Pressed ceramic tiles are created through a dry-pressing method, in which finely milled clay, feldspar, and other raw materials are compacted under high pressure and then fired at high temperatures. This process results in dense, hard tiles with smooth surfaces and minimal porosity.

There are two main types of pressed ceramic tiles: glazed and unglazed. Glazed tiles feature a decorative glassy coating that enhances their appearance and improves water resistance. In contrast, unglazed tiles provide higher slip resistance, making them suitable for heavy-duty applications and outdoor use.

Pressed ceramic tiles are commonly used in a variety of settings, including flooring for residential, commercial, and institutional spaces, as well as wall coverings in bathrooms, kitchens, and wet areas. They are also ideal for high-traffic zones such as airports, malls, and metro stations.

Regulatory Framework: BIS Certification and IS 15622:2017

Pressed ceramic tiles are governed by the Indian Standard IS 15622:2017, which is enforced through the Ceramic Tiles, Sanitary Wares, and Laboratory Wares (Quality Control) Order, 2023, issued by the Ministry of Commerce and Industry.

Under this order, BIS certification is mandatory. Products must bear the ISI Mark to be manufactured, sold, or imported in India.

About IS 15622:2017

IS 15622:2017 specifies the technical requirements, performance criteria, and testing methods for pressed ceramic tiles. It ensures:

Key Requirements Under IS 15622:2017

Manufacturers must adhere to the following standards to comply with IS 15622:2017:

● Size and Dimensional Tolerances: Tiles must conform to their declared nominal sizes (e.g., 300x300 mm, 600x600 mm). This includes checks for flatness, squareness, thickness, and side straightness. Adhering to these tolerances helps maintain alignment during installation and ensures uniform joints.

● Surface Quality: There are limits on visible surface defects, including pinholes, blisters, cracks, chips, and glaze inconsistencies, as well as pattern misalignment in printed tiles. Controlling these defects is crucial for aesthetic appeal and consumer satisfaction.

● Water Absorption: Tiles are classified based on their water absorption rates (e.g., Group B1a: ≤0.5%, Group BIII: >10%). Lower absorption values indicate higher density and better frost resistance.

● Breaking Strength and Modulus of Rupture: These parameters assess the durability of tiles under load.

●  Impact Resistance (Coefficient of Restitution): Tiles must be able to resist cracking under mechanical stress.

● Scratch and Abrasion Resistance: This is particularly important for high-traffic areas (the PEI rating system may apply).

● Chemical Resistance: Tiles must be resistant to acids, alkalis, household chemicals, and pool water, which is essential for kitchens, laboratories, and commercial spaces.

● Thermal Shock Resistance: Tiles should withstand sudden temperature changes.

● Moisture Expansion: This feature prevents cracking or warping due to humidity absorption over time. 

Testing Parameters for BIS Certification

BIS mandates comprehensive testing to ensure the tiles meet the quality benchmarks. Key tests include:

● Dimensions and Surface Quality

● Water Absorption

● Moisture Expansion

● Breaking Strength

● Modulus of Rupture

● Impact Resistance

● Thermal Shock Resistance

● Surface Abrasion Resistance

● Chemical Resistance

All tests must be conducted in BIS-approved laboratories, using procedures detailed in the standard.

BIS Certification Process for Pressed Ceramic Tiles 

The certification process involves the following steps:

●Application Submission: Apply to BIS through the online portal (Manak Online). Include product specifications, manufacturing details, and relevant test reports.

●Factory Inspection: BIS officials will inspect your manufacturing facilities, production controls, and internal testing capabilities.

●Sample Testing: Random samples of the product will be collected and tested in BIS-recognized laboratories.

● Evaluation and Grant of License: If your products comply with the required standards, BIS will grant a license permitting the use of the ISI mark on certified products.

●Post-Certification Surveillance: The BIS will conduct regular audits and sample checks to ensure ongoing compliance.
