The demand for tempered screen glass has increased rapidly due to the growing use of smartphones, tablets, laptops, smartwatches, and other electronic devices. Consumers now prefer high-quality screen protection products that provide durability, scratch resistance, and impact protection. To maintain product quality and consumer safety, the Bureau of Indian Standards (BIS) introduced standards for tempered screen glass under IS 19348:2025. Manufacturers and importers supplying tempered glass products in the Indian market must ensure compliance with these regulations to avoid legal issues and improve product credibility.

BIS certification for tempered screen glass helps ensure that products meet Indian safety and quality requirements. It also builds consumer trust and enhances brand reputation in the competitive electronics accessories market.

What is IS 19348:2025?

IS 19348:2025 is the Indian Standard developed for tempered screen glass used for electronic devices. This standard specifies the quality parameters, testing methods, safety requirements, and performance criteria for tempered glass screen protectors. The objective of this standard is to ensure that the products sold in India are durable, safe, and reliable for consumer use.

The standard covers several important factors, including:

• Impact resistance

• Surface hardness

• Transparency and optical clarity

• Adhesion quality

• Edge finishing

• Shatter resistance

• Thickness accuracy

• Scratch resistance

Manufacturers must comply with these technical requirements before selling their products in the Indian market.

Importance of BIS Certification for Tempered Screen Glass

BIS certification plays a major role in maintaining product quality and protecting consumers from low-grade or unsafe products. Tempered screen glass products without proper quality checks may crack easily, reduce screen visibility, or fail to provide adequate protection.

Some major benefits of BIS certification include:

1. Legal Compliance

BIS certification ensures that the product complies with Indian government regulations and quality control requirements.

2. Consumer Trust

Customers prefer certified products because they are tested for safety and durability.

3. Market Access

Manufacturers and importers can legally sell their products across India after obtaining BIS certification.

4. Improved Brand Reputation

Certified products create a positive image in the market and increase customer confidence.

5. Reduced Product Failures

Quality-tested tempered glass products have lower chances of defects and customer complaints.

Who Needs BIS Certification?

The following entities may require BIS certification for tempered screen glass products:

• Indian manufacturers

• Foreign manufacturers exporting to India

• Importers and brand owners

• OEM manufacturers

• Electronics accessory suppliers

Foreign manufacturers generally need to appoint an Authorized Indian Representative (AIR) for the certification process.

BIS Certification Process for Tempered Screen Glass

The BIS certification process for IS 19348:2025 involves several important steps. Proper documentation and product testing are necessary for approval.

Step 1: Application Submission

The manufacturer submits the BIS application with all required documents and product details.

Step 2: Documentation Review

BIS officials review technical documents, manufacturing details, and compliance information.

Step 3: Product Testing

Samples are tested in BIS-recognized laboratories to verify compliance with IS 19348:2025.

Step 4: Factory Inspection

In some cases, BIS may inspect the manufacturing facility to evaluate quality control systems and production capabilities.

Step 5: Grant of Certification

After successful testing and verification, BIS grants the certification license.

Step 6: Use of Standard Mark

The manufacturer can use the BIS Standard Mark on certified products.

Documents Required for BIS Certification

The following documents are commonly required:

• Company registration certificate

• Manufacturing license

• Factory address proof

• Product specifications

• Test reports from BIS-approved labs

• Quality management system details

• Trademark authorization letter

• Import-export code (for importers)

• AIR documents for foreign manufacturers

Accurate documentation helps avoid delays in the certification process.

Testing Requirements Under IS 19348:2025

Tempered screen glass products are tested for various quality and performance parameters. These tests help ensure product reliability and safety.

Common tests include:

• Hardness test

• Drop and impact resistance test

• Adhesion test

• Transparency test

• Dimensional accuracy test

• Fragmentation test

• Scratch resistance test

• Heat resistance test

Products that fail testing may require design or material improvements before re-application.

Challenges Faced by Manufacturers

Many manufacturers face difficulties during the BIS approval process due to technical and documentation requirements. Common challenges include:

• Incorrect technical documentation

• Failure in laboratory testing

• Delays in sample approval

• Lack of understanding of BIS guidelines

• Issues in factory quality control systems

Working with experienced BIS consultants can simplify the process and reduce approval time.
