HEAD PROTECTION

摘要

JSP says its Mk8 Evolution™ - or 'EVO8' - is the first helmet to offer serious protection from side impacts as well as severe crown impacts.rnAccording to the company, under EN14052 the helmet is required to protect against forces of more than 100 joules in the crown-impact area -compared to 49 joules required under EN397 - as well as protecting against a second impact to 49 joules on the same helmet initially tested. In addition, EN14052 requires protection from side impacts of 50 joules, i.e. to the same level required under the EN397 crown-impact test itself!
