Safety Requirements

1.System of Standards for Machinery Safety

The International Electrotechnical Commission (IEC) prepares international standards for all electrical, electric and related technologies, and the International Organization for Standardization (ISO) prepare international standards for all technologies other than electrical and electric technologies (machinery and management). European countries often take the initiative in proposing the standards and establishing them as ISO/IEC international standards.

Accelerated Globalization

1.Europe's EN Standards are produced by CEN/CENELEC.

2.IEC/ISO international standards are implemented without duplicating the efforts of various agreements.

3.Member countries of the WTO/TBT Agreements shall ensure the adoption of international standards as own national standards.

International Standards and Design of Machines and Devices

2.Situation by Country

(1) Europe

● EC Directives and the Machinery Directive

There are approximately 300 EC Directives issued for harmony in Europe. The EC Directives are equivalent to law in 18 countries in Europe. The EC Directive for machinery is called the Machinery Directive. The Machinery Directive (EC Directive 98/37/EC) restricts the export to Europe of machinery without the CE Marking as of January 1, 1995.
The Machinery Directive requires that machinery satisfy the three pillars of safety: mechanical safety, electrical safety, and worker safety. Specifically, among other regulations, EN 292 must be satisfied for machinery, EN 60204-1 and IEC 60204-1 for electrical systems, and VBG for accident prevention.
The new directive (2006/42/EC) was issued June 9, 2006. It will be implemented from December 29, 2009.

● Low-voltage Directive (LVD)

According to the EC Directive (EC Directive 2006/95/EC), low voltage devices are devices that operate at 50 to 1,000 VAC or 75 to 1,500 VDC. The LVD applies to almost all electrical devices from electrical household appliances and office equipment to industrial electrical machinery. The LVD pertains to electrical safety in the Machinery Directive, along with the EMC Directive.

● EMC Directive

The EC Directive for EMC devices is called the EMC Directive (EC Directive 89/336/EEC and New EMC Directive 2004/108/EC are effective.). EMC stands for "electromagnetic compatibility." When measures have been taken for both electromagnetic interference (EMI) and electromagnetic susceptibility/immunity (EMS), the device is called electromagnetically compatible, which means that EMC measures have been successfully applied.

● CE Marking

The CE Marking is a mark of compliance with the EC Directives. The CE Marking indicates that the product complies with the stipulated level of protection in all relevant EC Directives. Devices labeled with the CE Marking may be imported and exported to Europe without restriction. You might call the CE Marking a “passport” to Europe.

● Relation between the EC Directives, EN Standards, and CE Marking.

As explained above, all relevant EC Directives must be satisfied for a product to be labeled with the CE Marking. EN Standards complement the EC Directives. Satisfying the EN Standards alone, however, does not result in the EC Directives being satisfied. Countermeasures for product liability is mainly required in manuals and catalogs.

● Essential Safety Requirements

These basic requirements are listed in Machinery Directive Appendix I. The Preliminary Observations of the Annex I of Machinery Directive are introduced below.

1.The obligations laid down by the essential health and safety requirements apply only when the corresponding hazard exists for the machinery in question when it is used under the conditions foreseen by the manufacturer. In any event, requirements 1.1.2, 1.7.3 and 1.7.4 apply to all machinery covered by this directive.

2.The essential health and safety requirements laid down in this Directive are mandatory. However, taking into account the state of the art, it may not be possible to meet the objectives set by them. In this case, the machinery must as far as possible be designed and constructed with the purpose of approaching those objectives.

3.The essential health and safety requirements have been grouped according to the hazards which they cover. Machinery presents a series of hazards which maybe indicated under more than one heading in this Annex. The manufacturer is under an obligation to assess the hazards in order to identify all of those which apply to his machine; he must then design and construct it taking account of this assessment.

● European Harmonized Standards

Standards for countries in the European region are unified by CEN and CENELEC. The unified standards are called European Norm (EN) and "EN" is added to the front of the standard numbers. When new EN Standards are established, each country in the region must replace its relevant domestic standard with the EN Standard normally within six months. Applicable standards for products intended are not indicated in the EC Directives. The EN Standards that must apply are published separately in the Official Journal of the European Communities (OJEC). Manufacturers are therefore necessary to determine the design specifications based on the EN Standards published in the OJEC. In addition to official EN Standards, Drafts of European Standards (prEN), Harmonization Documents (HD), European Pre-standards (ENV), and CEN Reports (CR) are also published.

● Product Liability

The General Product Safety Directive and Product Liability Directive are complementary regulations but their scope is not identical. The Product Liability Directive applies to virtually all products, while the General Product Safety Directive applies only to new, used, and reconditioned products intended for or used by consumers. Both regulations, however, include areas of uncertainty. Therefore, to be especially careful, a manufacturer must compare the individual provisions of all directives that apply to its product.

● Occupational Safety and Health Administration (OSHA)

The Occupational Safety and Health Act (OSHA) passed in 1970 to provide safe and healthy working conditions. Part 1910 of the 29th Code of Federal Regulations (CFR) gives specific standards. Subpart O of Part 1910 sets standards for machinery and machine guarding, and divides into Part1910.211 to Part 1910.219.

1910.212General requirements for all machines
1910.213Woodworking machinery requirements
1910.214Cooperage machinery
1910.215Abrasive wheel machinery
1910.216Mills and calenders in the rubber and plastic industries
1910.217Mechanical power presses
1910.218Forging machines
1910.219Mechanical power-transmission apparatus

Part1910.212 covers general requirements for all machines. The main points in Part1910.212 are given below.

Paragraph (a)(1)

One or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards such as those created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks. Examples of guarding methods are barrier guards, two-hand tripping devices, electronic safety devices, etc.

Paragraph (a)(3)(ii)

The point of operation of machines whose operation exposes an employee to injury shall be guarded.The guarding device shall be in conformity with any appropriate standards, therefore, or, in the absence of applicable specific standards, shall be so designed and constructed as to prevent the operator from having any part of his body in the danger zone during the operating cycle.

● American National Standards Institute (ANSI)

ANSI is an independent standards organization in the USA. It does not create any standards by itself, but rather approves and registers US standards created in various fields. For example, in 1976 ANSI approved the Underwriters Laboratories (UL), which was established by the fire insurance industry. Manufacturers of industrial robots in Japan and many other countries worldwide use the requirements for safety of industrial robots and robotic systems given in ANSI/RIA R15.06, which forms the basis of ISO 10218. ANSI/B11.19 safety standards for machine tools were established in 2003 and have become important standards.

1. Safety of Machine Tools

The American Society of Mechanical Engineers (ASME) collaborates in creating ANSI Standards, which are often adopted as ANSI B Standards. The main safety standards for machine tools are stipulated by ANSI B11.

US Standards (B11 Standards)

ANSI B11.1Mechanical power presses
ANSI B11.2Hydraulic power presses
ANSI B11.3Power press brakes
ANSI B11.4Shears
ANSI B11.5Iron workers
ANSI B11.6Lathes
ANSI B11.7Cold headers and cold formers
ANSI B11.8Drilling, milling, and boring machines
ANSI B11.9Grinding machines
ANSI B11.10Metal sawing machines
ANSI B11.11Gear-cutting machines
ANSI B11.12Roll forming and roll bending machines
ANSI B11.13Automatic bar and chucking machines
ANSI B11.14Coil slitting machines

ANSI B11.16Metal powder compacting presses
ANSI B11.17Horizontal hydraulic extrusion presses
ANSI B11.18Machinery and machine systems for processing of coiled strips, sheets, and plates
ANSI B11.19Performance criteria for the design, construction, care, and operation of safeguarding
ANSI B11.20Integrated manufacturing systems/cells

ANSI B11.19 (Safeguarding when Referenced by the Other B11 Machine Tool Safety Standards - Performance Criteria for the Design, Construction, Care, and Operation) sets standards for barrier guards often referenced by other ANSI B11 standards. The main points in B11.19 are given on the next paragraph.

Purposes for Using Safety Equipment

To ensure the safety of operators, safety and protective equipment is designed to prevent any hazardous machine motion or stop the machine when the operator's hand or other body part enters the hazard zone. The following items are demanded of safety and protective equipment.

1. Interlocked Protective Device

A protective barrier must be installed that is equipped with an interlock function that prevents the machine from operating unless the hazard is eliminated.

Safety related systems must be provided with a safety function that prevents the machine from starting due to a single failure.

Interlock equipment must be equipped with a tamper resistant function.

2. Presence-sensing Device

A device equipped with a function that detects the operator's hand or other body part, and outputs a signal to prevent any hazardous machine motion or to stop the machine.

The device must have a single failure detection function.

When mounted in a location that requires adjustment of the operating conditions, a blanking function must be provided.

3. Safety Mat

The Safety Mat is a device that detects the presence of an operator who steps on it, and prevents any hazardous machine motion.

The device must have a single failure detection function.

2. Safety of Industrial Robots

● Industrial Safety and Health Act

The amended Industrial Safety and Health Act went into effect in 2006, with the purpose of providing an environment for the promotion of independent safety and health activities in offices. For example, the Act includes requirements to investigate dangers and hazards in the workplace and take necessary measures against them. The Act incorporates a framework to identify dangers and hazards, evaluate risks, and implement measures to reduce these risks.

● Guidelines for Comprehensive Machinery Safety Standards

In July 2007, the Ministry of Health, Labor and Welfare in Japan amended its Guidelines for Comprehensive Standards of Machinery, which was originally issued in June 2001 in response to the basic safety standards provided in ISO 12100. These Guidelines stipulate the procedure for manufacturers to use in reducing safety risks and achieve designs that take safety into consideration in the manufacture of production equipment and machinery, and also request that users provide safety measures when they introduce and use the equipment and machinery.
In other words, the measures that ensure safety in machinery include measures that manufacturers build-in at the design stage and measures that users must take when using the machinery. However, the Guidelines also clarify the fact that the measures that manufacturers build-in at the design stage must naturally precede the measures taken by the users.
The following diagram shows the flow of achieving machinery safety based on the information in the Guidelines for Comprehensive Machinery Safety Standards.

Safety Procedure for Machinery

*1.In the Attachment, "risk assessment" is referred to as "assessment of hazards and dangers".

*2.In the Attachment, "hazards" is referred to as "hazards and dangers".


The regulations and standards of individual countries must be brought in line with international standards to remove trade barriers and thus ensure free trade worldwide. To that end, Japan accepted the terms of the World Trade Organization (WTO), becoming a member and signatory to the WTO Agreement as well as the TBT Agreement (Technical Barrier Treatment). In 1995, Japan declared its commitment to a system of global cooperation. Growing pressure to adopt international standards triggered a complete overhaul of the JIS standards, which were enacted under the Industrial Standardization Law, to bring them in line with the framework of the international IEC and ISO standards.The new JIS standards will be shifted to the hierarchical system comprised of type A (basic safety standards), type B (generic safety standards) and type C (machine safety standards) standards so that Japanese standards will conform to international standards.

(8) Industry Standards

● Semiconductor Manufacturing Equipment Guideline SEMI Standards

SEMI, which is an abbreviation of Semiconductor Equipment and Materials International, was established in 1970 as an international industry association for semiconductor manufacturing equipment and materials manufacturers. SEMI standards have been established as independent industry standards. There are separate standards for materials (M Series), Facilities (F Series), Flat Panel Displays (D Series), and Traceability (T Series), and the S Series governs environment, health and safety (EHS). These standards have been employed by many equipment users, primarily in the United States. Their headquarters are in California, and there are 11 offices in 8 countries around the world, including in Tokyo.
