Overview

EN ISO 11148-1:2011 - “Hand-held non-electric power tools - Safety requirements - Part 1: Assembly power tools for non-threaded mechanical fasteners” is a CEN-adopted ISO standard that specifies safety requirements for hand-held, non-electric assembly power tools used to install, tighten or remove non-threaded fasteners (for example, rivets, rivet nuts, plugs and lockbolts) from one side of a workpiece. Covered tools include breakstem and mandrel riveting tools, breakstem lockbolt tools and rivet nut setters. The standard applies to tools powered by compressed air, hydraulic fluid or internal combustion engines (where applicable) and addresses foreseeable misuse except operation in potentially explosive atmospheres.

Key Topics and Requirements

EN ISO 11148-1 focuses on hazard identification and risk reduction for hand-held assembly power tools. Core technical topics include:

• Mechanical safety: guarding, structural strength and prevention of hazards from moving parts.
• Thermal safety: hot-surface assessment and protection against burns.
• Noise and vibration: requirements for noise reduction and vibration assessment plus verification tests.
• Controls and prevention of unintentional start: design of actuators, control layouts and safety interlocks.
• Materials and emissions: risks from materials or substances processed, used or exhausted by the tool.
• Ergonomics: operator support, handling, balancing (suspension/balancer use) and human-machine interface.
• Verification and testing: procedures for measuring noise, vibration, unintentional start, and structural aspects.
• Information for use: marking, warning labels, instruction handbook, operating and maintenance instructions, and specified data to accompany the tool.

The standard is a type-C standard and takes precedence where its requirements differ from relevant type-A or type-B standards.

Practical Applications and Who Uses It

EN ISO 11148-1 is intended for:

• Manufacturers and designers of pneumatic, hydraulic or combustion-powered hand-held riveting and fastener tools - to design compliant, safer tools.
• Product safety and compliance engineers - to demonstrate conformity with safety requirements and support CE/Machinery Directive obligations (see Annex ZA relationship to EU Directive 2006/42/EC).
• Test laboratories and certifiers - for verification tests on noise, vibration, unintentional start and construction.
• Purchasers, maintenance teams and safety officers - to understand required markings, user instructions and safe operation/maintenance practices.

4.2.1 Surfaces, edges and corners
Accessible parts of assembly power tools for non-threaded mechanical fasteners, except the inserted tool,
shall not have sharp edges or angles or rough or abrasive surfaces; see ISO 12100:2010, 6.2.2.1.
4.2.2 Supporting surface and stability
Assembly power tools for non-threaded mechanical fasteners shall be so designed that they can be laid aside
and remain in a stable position on a plane surface.
4.2.3 Collection of ejected stems
Bottles and/or deflectors shall be fitted to the rear of blind riveters and break stem lockbolt tools to either
collect or deflect stems in such a way that their forcible ejection does not cause operator injury.
4.2.4 Hydraulic fluid ejection
Hydraulic systems of the assembly power tool for non-threaded mechanical fasteners shall be enclosed so as
to provide protection from high-pressure fluid ejection.
4.2.5 Power tool construction
The assembly power tool for non-threaded mechanical fasteners shall be so designed and constructed as to
prevent the loosening or loss of components during expected use, including rough handling and occasional
dropping, which can compromise its safety functions. Verification shall be carried out in accordance with 5.5.
4.3 Thermal safety
Surface temperatures of parts of the assembly power tool for non-threaded mechanical fasteners which are
held during use or that can be inadvertently touched shall follow the provisions of ISO 13732-1 and
ISO 13732-3.
Pneumatic tools shall be designed to minimize the cooling effects of exhaust air on the handles and other
gripping zones.
4.4 Noise reduction
The assembly power tool for non-threaded mechanical fasteners shall be designed and constructed so that
the emission of noise is reduced to the lowest level, taking account of technical progress and the availability of
means of reducing noise, in particular at source. Principles for designing power tools with reduced noise
emission are contained in ISO/TR 11688-1 and ISO/TR 11688-2.
The noise emission from using power tools has three main sources:
 the assembly power tool for non-threaded mechanical fasteners itself;
 the inserted tool;
 the workpiece.
NOTE Generally, the noise emitted due to the characteristics of the workpiece cannot be controlled directly by the
manufacturer of the assembly power tool for non-threaded mechanical fasteners.
ISO 11148-1:2011(E)
Typical sources of noise emitted by the assembly power tool for non-threaded mechanical fasteners itself are
a) the motor and drive mechanism,
b) the exhaust air or gases, and
c) vibration or impact-induced noise.
Where the exhaust air or gases are the major contributor to the noise, means to reduce the noise, for example
a silencer or equivalent means, shall be included in the design.
Alternatively, where practicable, the exhaust air or gases may be piped away from the operator in a hose.
Vibration-induced noise can often be reduced by vibration isolation and damping.
This list is not exhaustive; where alternative technical measures for noise reduction, with greater efficiency,
are available, they should be used by the manufacturer.
4.5 Vibration
The assembly power tool for non-threaded mechanical fasteners shall be designed and constructed so that
the vibration is reduced to the lowest level at the handles and at any other parts of the tool in contact with the
operator's hands, taking account of technical progress and the availabi
