BIS ISI Mark Certification for Hand Operated Chain Pulley Blocks – IS 3832:2005

Chain pulley blocks are essential lifting tools used in warehouses, manufacturing units, ports, construction sites, and workshops. These manually operated lifting devices enable safe and efficient handling of heavy loads. To ensure safety, durability, and consistent quality, the Bureau of Indian Standards (BIS) has made ISI mark certification mandatory for hand-operated chain pulley blocks under IS 3832:2005.

This article explains the importance of certification, the standard's key requirements, and how Standphill India helps you get BIS certified without complications.

What is IS 3832:2005?

IS 3832:2005 is the Indian Standard that covers the specifications for hand-operated chain pulley blocks used for lifting and lowering loads by pulling the hand chain. The standard applies to blocks of the hook suspension type having one or more falls of load chain.

Key requirements include:

Rated load capacity and lifting height

Chain dimensions, tensile strength, and mechanical properties

Load and performance tests (proof load, overload, and endurance tests)

Construction materials and corrosion resistance

Marking and labeling requirements

Products certified under this standard are verified for structural integrity, mechanical safety, and operational efficiency.

Why BIS Certification is Mandatory

According to the Ministry of Commerce and Industry's Quality Control Orders (QCOs), hand operated chain pulley blocks must comply with IS 3832:2005 and bear the ISI mark to be sold or imported in India.

Compliance Benefits:

Ensures mechanical safety and load-handling performance

Mandatory for public procurement and industrial tenders

Required for sale on retail and e-commerce platforms

Prevents legal penalties and product bans under the BIS Act, 2016
