BIS Certification for Personal Fall Arrest Systems – Flexible Horizontal Lifeline Systems as per IS 3521 (Part 8):2021

Introduction

Work at height remains one of the most significant occupational safety risks across construction, industrial maintenance, infrastructure, and energy sectors. To mitigate the risk of fatal falls, Personal Fall Arrest Systems (PFAS) are essential safety solutions. Among these, Flexible Horizontal Lifeline Systems enable workers to move safely along elevated horizontal paths while remaining continuously protected.

To ensure safety, reliability, and uniform quality, the Bureau of Indian Standards (BIS) has introduced IS 3521 (Part 8):2021, which specifies requirements for Flexible Horizontal Lifeline Systems. BIS certification under this standard assures that such systems meet stringent design, performance, and testing benchmarks aligned with international safety practices.

Standphill India provides comprehensive BIS certification consultancy for manufacturers of fall protection equipment, ensuring compliance with IS 3521 (Part 8):2021 and enhancing workplace safety standards across India.

What Is IS 3521 (Part 8):2021?

IS 3521 (Part 8):2021 is an Indian Standard that defines the technical and performance specifications for flexible horizontal lifeline systems used as part of personal fall arrest systems.

This standard is aligned with ISO 16024:2005, ensuring that products manufactured and certified in India meet globally recognized safety and performance criteria. It addresses critical aspects such as system design, materials, strength, installation, testing methods, and user safety.

BIS Certification Process

Step 1: Application Submission

Submission of technical documents, product details, manufacturing information, and quality control procedures to BIS.

Step 2: Product Testing

Samples are tested at BIS-recognized laboratories as per IS 3521 (Part 8):2021 requirements. Testing includes static load tests, dynamic performance tests, and material analysis.

Step 3: Factory Inspection

BIS officers conduct factory inspection to verify manufacturing capability, quality control systems, testing infrastructure, and compliance with standard requirements.

Step 4: Grant of License

Upon successful compliance with all requirements, BIS issues the license allowing use of the ISI Mark on certified products.

Step 5: Surveillance and Renewal

Regular surveillance audits and license renewal as per BIS guidelines to maintain certification validity.
