Helmet Testing Services

Presto Laboratories can provide extensive testing of industrial safety helmets based on the specification of industrial safety helmets. The testing program would be able to test the protective performance, structural integrity, and durability of the helmets under mechanical, environmental, and functional distressing conditions as provided in the Indian Standard.

These are the tests that aid in assuring that the safety helmets provide enough head protection to the users that work in industrial, construction, electrical, and hazardous workplaces, as well as comply with the statutory and customer request requirements.

Purpose of Helmet Testing

The safety helmets offered by industries must be used to shield the user against impact, penetration, and other industrial hazards. As time passes, the ability of the helmet to resist exposure to sunlight, temperature fluctuation, moisture, and mechanical strain could impair its ability.

The testing, according to IS 4151, is mandatory to

• Verify impact energy absorption capability.
• Assess resistance to penetration by sharp objects.
• Evaluate helmet performance after environmental conditioning.
• Check the fitting, stability, and effectiveness of the retention systems.
• Check that there is a BIS certification and that safety standards are observed at the workplace.

All tests at Presto Laboratories are done as per the requirements, conditioning requirements, and acceptance criteria stipulated in the IS 4151.

Impact Absorption Test

The impact absorption test is a test that measures the effectiveness of the helmet at absorbing the impacting force given to the head.

In this test:

• The helmet is mounted on a standardized headform.
• A striker of specified mass is dropped from a defined height.
• The power passing through the helmet is gauged.
• The helmet should restrict the force radiated in the highest permissible values referred to in IS 4151 and must be able to absorb and dissipate impact energy when subjected to such a force.

Penetration Resistance Test

This test assesses the helmet’s resistance to penetration by sharp or pointed objects.

• A sharp striker is dropped from a specified height onto the helmet surface.
• The test is to check the penetration of the striker into the helmet and contact with the headform.

Being able to pass by this test makes it clear that the helmet shell is sufficiently protective against falling or flying objects at work.

Retention System Strength Test

The retention system (chin strap) plays a vital role in keeping the helmet in place over the head during use.

This test checks:

• Strength of the retention system under applied load.
• Elongation and slippage of straps.
• Integrity of attachment points.

The helmet must withstand the specified load without failure or excessive elongation.

Conditioning Tests

To simulate real-world usage conditions, helmets are subjected to environmental conditioning before mechanical testing.

Conditioning includes exposure to:

• High temperature
• Low temperature
• Water immersion
• Artificial ageing (where necessary)

After the conditioning phase, helmets are again tested on the effectiveness of impact absorption and penetration resistance to ensure there is no impairment in their performance.

Shell Rigidity and Deformation

This test evaluates the resistance of the helmet shell to lateral deformation under load.

• A specified force is applied to the helmet shell.
• The deformation is gauged and compared to the allowable range.

That is to make sure that the helmet remains in its structural integrity and fit while in use.

Visual and Dimensional Inspection

In addition to performance testing, helmets undergo the following:

• Surface inspection to detect defects, cracks, or sharpness.
• Dimensional checks for shell thickness, peak length, and overall construction.
• Verification of markings and labeling as required by IS 4151.

Test Execution and Quality Assurance

All the tests of helmets at Presto Laboratories are conducted on generally recognized test equipment and standardized headforms. All the steps of testing are recorded in writing, and every measurement taken is recorded so that they can be traced.

Our testing process includes:

• Sample identification and receipt inspection.
• Pre-conditioning as per standard requirements.
• Controlled execution of mechanical and environmental tests.
• Post-test inspection and evaluation.
• Independent technical review of results.

Test Reports and Deliverables

Clients will have a test report in which they will receive:

• Description of samples tested.
• Applicable standard reference (IS 4151).
• Test methods and conditions.
• Measured values and observations.
• Pass/fail assessment based on acceptance criteria.

Reports are suitable for QAI certification, internal quality assurance, and customer submissions.

Testing Infrastructure

Our lab is equipped with world-class testing technology to replicate real-world automotive stresses:

• Drop & Impact Testers – simulate crash impact energy.
• Penetration Testing Machines – verify shell toughness.
• Retention Strap Testing Rigs – check strap strength & stability.
• Abrasion & Scratch Testers – ensure visor clarity and durability.
• Flammability Chambers – check resistance to fire hazards.

Standards Followed for Helmet Testing

The test of a helmet done at Presto Laboratories is guided by a systematic plan of a set of Indian standards that determine safety, strength, and performance tests on various types of helmets. These standards inform the testing of helmets in terms of impact, penetration, environmental exposure, and long-term use to ensure that the results remain the same for the domestic and industrial applications.

The protective helmets used in IS 4151 are very common and concentrate on the area of impact absorption, penetration resistance, retention system strength, and the entire construction. It defines how helmets should perform during sudden impact and under different environmental conditions.

IS 2925 applies to industrial safety helmets used in construction and factory environments. It checks shock absorption, structural strength, and resistance to external forces faced during daily operations.

IS 2745 is used for nonmetal helmets designed for firemen and civil defense personnel. It includes testing for heat resistance, flame exposure, and impact protection under emergency conditions.

IS 9562 covers helmets designed for police forces. It evaluates durability, strength, and performance under field use where impact and stress are common.

IS 9973 focuses on visor testing. It verifies transparency, scratch resistance, and visibility that is significant in safe visual conditions in riding or industrial applications.

Collectively, these standards create a thorough testing framework that aids in checking the safety of helmets, their wear and tear, and certification or market placements.
