Question:

Is the heavier hat the better the quality?

Is the heavier hat the better the quality?

Answer:

On the premise of ensuring safety performance, the lighter the weight of the helmet, the better to reduce the neck fatigue caused by the long wearing of the operator.The weight of the helmet shall not exceed 430 grams on the small, middle, and along sides of the roll;The weight of the large safety helmet shall not exceed 460 grams;The weight of a cold helmet shall not exceed 690 grams (not including additional parts above the weight requirements).
Safety cap size requirements: internal dimensions, shell cap visor, brim, horizontal spacing, vertical spacing, height, wear protrusions and air holes.The vertical spacing and the wearing height are two important dimensions of the helmet.The vertical spacing refers to the distance between the top of the helmet and the inside of the cap when the helmet is worn (excluding the space of the top reinforcement).The size requirement is 25 millimeters to 50 millimeters.Wearing height refers to the axial distance from the bottom edge of the helmet to the top of the head when the helmet is worn.The size requirement is 80 millimeters to 90 millimeters.The vertical spacing is too small to directly affect the stability of the helmet wear. Any disqualification of these two requirements will directly affect the overall safety of the helmet.
Safety performance refers to the protective performance of the helmet, including basic performance requirements and special performance requirements. It is an important indicator to determine whether the helmet products are qualified or not.The helmet standard GB2811-1989 clearly specifies the requirements that helmet products should meet.
