JASPER V

Lightweight Safety Helmet

Lamp Bracket: Users have the option to attach a headlamp to the helmet, enhancing visibility and utility in low-light conditions.
Hanging Clip/Cable Clip: A clip is provided at the back of the helmet for user convenience, allowing for easy hanging or attachment of cables.
Adjustability: The helmet features zip adjustment for accommodating head measurements ranging from 52 to 60 cm. Additionally, chin strap adjustment options are available for a secure and comfortable fit.
Material Composition: The helmet is constructed with a Polypropylene (PP) shell material, known for its lightweight yet durable properties. The harness lining is made of LLDPE (Linear Low-Density Polyethylene) and LDPE (Low-Density Polyethylene), which adds comfort and flexibility.
Temperature Range: The helmet is designed to withstand temperatures from -10°C to +50°C, making it suitable for use in various environmental conditions.
Size: The helmet is adjustable within the range of 52 to 60 cm, ensuring a proper fit for a wide range of users.
How to clean: Use a low-concentration mild & and non-abrasive clwaning solution. DIp a clean cloth & gently wipe the entire surface of the helmet. Pay attention to areas that may accumulate dirt, sweat, or other contaminants.

Shock absorption test: The helmet shall be mounted on a wooden head form of appropriate size. The wooden striker weighing 3 kgs and having a horizontal striking face of 180 mm X 180 mm, shall be raised to a clear height of 1.5 m above the point of contact with the helmet and allowed to fall freely. A record of the force transmitted during impact shall be made. Method of testing penetration resistance: Mount helmet on an appropriate headform. Drop freely a plumb bob of 500 gms mass with a conical steel point having an included angle of 36 degrees and a spherical point radius of not more than 0.5 mm from a clear height of 3.0 m with the pointed end downwards on to the top of the crown of the helmet. Examine the helmet for piercing or denting, failure of any integral parts etc. Method of testing flammability resistance: With the helmet upside down and the burner angled at 45 degrees to the vertical, the end of the flame shall be applied to the outside of the shell at any suitable point between 50 & 100 mm from the crown for a period of 10 seconds. The plane tangential to the test point shall be horizontal. The shell shall be examined for flaming 5 seconds after removal of the flame. Method of testing electrical resistance: Invert the helmet and place it on a frame in a suitable container. With a solution of 6g/l of water, fill the container and the helmet to within 12mm of the junction of the brim and the dome, or if the helmet is provided with holes to a depth of 12 mm below the holes. Allow the helmet to remain in the solution for a period of 18 to 24 hours and maintain the temperature of 25 degrees to 35 degrees Centigrade during this period. Then apply an alternating voltage of 2000 V at 50Hz for 1 minute between electrodes placed in the solution inside and outside the helmet respectively. If no electrical breakdown occurs, disconnect the high voltage supply and connect a milliammeter in the circuit on each side of the electrode. Raise the test voltage slowly observing the ammeter reading, until the applied voltage is 2000V. Method of testing water absorption: The sample used for shock absorption is used for carrying out this test. Weigh the sample (full shell). Immerse for 24 hours in water at a temperature of 25 to 35 degrees centigrade. Remove from water, dry the surfaces by wiping them and weigh again. Report the average gain in mass as a percentage. Method of testing heat resistance: Place the shell in an oven maintained at a temperature of 93 degrees centigrade. The shell shall be shielded from direct radiation during the test. Remove the shell from the oven and examine for separation, distortion or softening.
