本年度は,国際規格については11件(DIS,NWIP,SR,CIB)の国際規格等の審議を実施 した。改訂作業については,ISO13850,ISO14122,ISO19353などに加えて,新規作業項 目として,ISO12100とタイプB規格を結ぶBridge documentであるISO/TR22100-1や人 間工学要求事項を安全規格に導入するためのガイドである ISO/TR22100-3 などの作成作業 を実施した。
JIS原案の作成については,昨年度からJIS B 9710原案の改訂作業,及びJIS B 9705-2新 規作成作業を実施し,前者については審議を終了したが,後者については,次年度も作業を 続けることとなっている。
上述の規格審議に加えてさらに特筆すべきこととして,本年度は 4 月の冒頭に第 17 回
ISO/TC199国際会議が初めて日本で開催され,海外から多くの出席者を受け入れることがで
き,また日本からもオブザーバ参加を含め多数の出席者を得ることができたことは喜ばしい 限りであった。
来年度は,国際規格審議については本年度の作業を継続し,また新規・改訂作業として使用 上の情報やISO14118(予期しない起動の防止)の作業も追加されることとなる。
さらに,本年度新たに ISO/TC199 内に設置されたスタディグループ(ヒューマン‐マシン インタラクションのためのセーフティデータ)の調査研究が本格的に始まることが予想され,
このスタディグループの日本開催が予定されている。
委員の皆様には,来年度におかれましてもこれらの活動にご協力お願いする次第です。

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that which is normally published as an International Standard (“state of the art”, for example), it may decide by a simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely informative in nature and does not have to be reviewed until the data it provides are considered to be no longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.

4 Fault masking
4.1 Principle
A common approach in the design of safety related circuits is to series connect devices with potential free contacts e.g. multiple interlocking devices connected to a single safety logic controller which performs the diagnostics for the overall safety function. Although In such applications a single fault will in most cases not lead to the loss of the safety function and will be detected, in practise problems sometimes occur.
It is foreseeable that more than one movable guard will be open at the same time or in a sequence, e. g. due to subsequent fault finding procedure or as part of the regular operation of the machine.
Due to the serial connection of the contacts, faults in the wiring or contacts, detected by the logic unit may be masked by the operation of one of the other (non-faulty) in series connected devices. As a result the operation of the machine is possible while a single fault is present in the SRP/CS. This can in consequence allow the accumulation of faults leading to an unsafe system.
Figure 6 to Figure 8 show examples for fault masking in situations with movable guards with series connected devices.
