The demand for tempered screen glass has increased rapidly due to the growing use of smartphones, tablets, laptops, smartwatches, and electronic display devices. Consumers today expect strong, scratch-resistant, and safe screen protection products that offer durability and reliability. To ensure product quality and consumer safety, the Bureau of Indian Standards (BIS) has introduced compliance requirements for tempered screen glass under IS 19348:2025.

BIS certification for tempered screen glass helps manufacturers, importers, and sellers ensure that their products meet Indian safety and quality standards. Products complying with IS 19348:2025 gain better trust in the Indian market and can be legally sold without compliance-related issues.

What is BIS Certification for Tempered Screen Glass?

BIS certification is a quality assurance process regulated by the Bureau of Indian Standards. It confirms that a product complies with applicable Indian Standards related to safety, durability, performance, and reliability.

Under IS 19348:2025, tempered screen glass products are evaluated for various technical and safety parameters. The standard focuses on ensuring that the screen protection glass offers proper impact resistance, transparency, hardness, edge finishing, adhesion quality, and safe usage for consumers.

Manufacturers and importers dealing in tempered screen glass products must ensure compliance with this standard before introducing products into the Indian market.

Importance of IS 19348:2025

The implementation of IS 19348:2025 is important because low-quality tempered glass products can easily crack, reduce touch sensitivity, or fail to protect electronic device screens. Inferior products may also create safety hazards due to sharp fragments after breakage.

The standard ensures:

• Better screen protection quality
• Improved impact resistance
• Enhanced user safety
• Standardized manufacturing process
• Reliable product performance
• Increased consumer confidence
• Reduced risk of counterfeit products

For businesses, BIS certification also improves market credibility and helps in gaining customer trust.

Products Covered Under IS 19348:2025

The standard generally applies to tempered screen protection glass used for:

• Smartphones
• Tablets
• Smartwatches
• Laptop displays
• Camera screens
• Automotive infotainment displays
• Other electronic display devices

Both domestic manufacturers and foreign manufacturers exporting tempered glass products to India may need BIS approval depending on regulatory requirements and product categories.

Key Requirements for BIS Certification

Manufacturers applying for BIS certification under IS 19348:2025 must comply with several quality and technical requirements. These may include:

1. Material Quality

The glass material used should meet the required strength and transparency standards. Poor-quality raw materials may fail testing procedures.

2. Surface Hardness

The tempered glass should possess adequate hardness to resist scratches and daily wear.

3. Impact Resistance

Products are tested for their ability to absorb shocks and prevent screen damage during accidental drops.

4. Adhesion Performance

The adhesive layer must provide proper fitting without bubbles or lifting issues.

5. Optical Clarity

The glass should maintain screen visibility, brightness, and touch sensitivity.

6. Edge Finishing

Proper edge polishing and finishing are important to avoid injuries and improve durability.

BIS Certification Process for Tempered Screen Glass

The BIS certification process involves several important stages. Businesses must carefully follow each step for successful approval.

Application Submission

The manufacturer submits the application along with technical documents, product specifications, and manufacturing details.

Product Testing

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

Factory Inspection

BIS officials may inspect the manufacturing facility to assess production quality, testing capabilities, and quality control systems.

Document Verification

The submitted documents, test reports, and compliance records are thoroughly reviewed.

Grant of License

After successful verification and compliance approval, BIS grants the certification license to the manufacturer.

Documents Required for BIS Approval

The following documents are commonly required:

• Company registration certificate
• Manufacturing license
• Product specification sheet
• Test reports
• Factory layout
• Quality control documents
• Trademark details
• Authorized representative details
• Import-export certificate (for foreign manufacturers)

Accurate documentation helps speed up the approval process.

Benefits of BIS Certification for Tempered Screen Glass

Obtaining BIS certification offers multiple business advantages:

• Legal market access in India
• Increased product credibility
• Better customer trust
• Improved product quality
• Competitive advantage
