Protective equipment for use in ice hockey - Part 2: Head protection for skaters (ISO 10256-2:2016)

This International Standard specifies performance requirements and test methods for head protectors for use in ice hockey and shall be used in conjunction with ISO 10256-1.
Note 1   The requirements of a clause take precident over a figure.   
Note 2   The intent of this International Standard is to reduce the risk of injury to the head without compromising the form or appeal of the game.
Note 3   Ice hockey is a sport in which there is a risk of injury.  This International Standard is intended only for helmets  used for ice hockey.  Ice hockey helmets afford no protection from neck or spinal injury. Severe head, brain or spinal injuries, including paralysis or death, may occur in spite of using an ice hockey helmet in accordance with this International Standard.

Varovalna oprema za uporabo pri hokeju na ledu - 2. del: Zaščita glave za drsalce (ISO 10256-2:2016)

Ta mednarodni standard določa zahteve glede učinkovitosti in preskusne metode za ščitnike za glavo za uporabo pri hokeju na ledu, uporabljati pa ga je treba skupaj s standardom ISO 10256-1. Opomba 1: Zahteve točke imajo prednost pred številsko vrednostjo.    Opomba 2: Namen tega mednarodnega standarda je zmanjšati tveganje za poškodbe glave brez vpliva na način ali privlačnost igre. Opomba 3: Hokej na ledu je šport, ki vključuje tveganja za poškodbe.  Ta mednarodni standard je namenjen le čeladam, ki se uporabljajo pri hokeju na ledu.  Čelade za hokej na ledu ne zagotavljajo nobene zaščite pred poškodbami vratu ali hrbtenice. V skladu s tem mednarodnim standardom lahko pride do hudih poškodb glave, možganov ali hrbtenice oziroma paralize ali smrti navkljub uporabi čelade za hokej na ledu. Zahteve in ustrezne preskusne metode veljajo (kjer je to primerno) za:
a) izdelavo in pokritost; b) ublažitev udarcev;
c) prepustnost; d) lastnosti zadrževalnih sistemov; e) vidno polje; f) označevanje in podatke. Ta mednarodni standard se uporablja za ščitnike za glavo, ki jih uporabljajo:
a) igralci, ki niso vratarji; in
b) nekateri funkcionarji (npr. sodniki).

Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

Introduction

Ice hockey is a sport in which there is a risk of injury. Ice hockey helmets afford no protection from neck

or spinal injury. Severe head, brain, or spinal injuries, including paralysis or death, can occur in spite of

using an ice hockey helmet according to this part of ISO 10256.

The intention of head protection used in ice hockey is to reduce the frequency and severity of localized

injuries to the head. The protective function is such that the force from impacts against the protector is

distributed and dampened and the penetration of objects is counteracted.

Part of the head protection for use in ice hockey consists of a helmet. To achieve the performance of

which it is capable and to ensure stability on the head, a helmet is intended to be as closely fitting as

possible consistent with comfort. In use, it is essential that the helmet is securely fastened, with any

chin strap or neck strap adjusted according to manufacturer’s instructions.

Subcommittee 5 is aware that specifications for the performance of the helmet are required to reduce

the risk of injury in ice hockey. There was consensus that most of today’s head protectors meet the

performance requirements of this part of ISO 10256. The goal of the subcommittee is to promote the

use of better materials and/or constructions as they become available to meet the future requirements

of the sport of ice hockey. Subcommittee 5 recognizes that in order to provide for comfort, fit and

use, helmets is intended to have a mass consistent with providing the appropriate performance

characteristics.

5.3 Field of vision

The upward field of vision is the solid angle bounded by the reference plane of the headform and a

second plane tilted 35° upwards from the reference plane. This second plane intersects the reference

plane at two points on the front surface of the headform that are 31 mm to the right and left of the

median plane.

The left horizontal field of vision is the solid angle bounded by a plane parallel and 31 mm to the left of

the median plane of the headform and a second plane perpendicular to the median plane (i.e. rotated

90° horizontally) and parallel to the lateral plane. The two planes intersect with the reference plane at

the front surface of the headform at a point located 31 mm to the left of the median plane.

The right horizontal field of vision is the solid angle bounded by a plane parallel and 31 mm to the right

of the median plane of the headform and a second plane perpendicular to the median p
