Full title and description

BS EN ISO 8662-9:1997 — Hand-held portable power tools — Measurement of vibrations at the handle — Part 9: Rammers. This is the British (BS) and European (EN) adoption of the International Standard ISO 8662-9, which specifies a laboratory test method to measure the hand-transmitted vibration at the handle of hand-held rammers (used in foundries, construction sites, etc.).

Abstract

Specifies a laboratory procedure for measuring the vibration magnitude at the gripping areas of hand-held rammers under defined test conditions and loads. The standard establishes measurement mounts, instrumentation, test conditions, data processing (frequency weighting and evaluation of vibration magnitude) and reporting conventions to allow comparison between tools of the same type.

• Edition / version: Edition 1 (ISO 8662-9:1996) — adopted as BS EN ISO 8662-9 in 1997.
• Number of pages: BS EN ISO adoption: typically shown as 18 pages (ISO original document recorded as shorter — edition and formatting vary by publisher).

Scope

This part of the ISO 8662 series defines a laboratory test method to determine the hand-transmitted vibration emitted at the handle of hand-held rammers when operated under specified test conditions and loads. It is intended as a type-test procedure to establish vibration levels for comparison between models and to provide data for exposure assessment. It does not prescribe workplace exposure limits or protective measures, but provides measurement and reporting rules used in product evaluation and risk assessment.

Key topics and requirements

• Definition of the ramming machine types and intended test conditions (specified loads, tool attachments and workpieces).
• Instrumentation and calibration requirements for accelerometers and data acquisition (frequency range and sensitivity).
• Mounting and handle interface arrangements to reproduce typical handgrip conditions during tests.
• Measurement procedures including measurement axes, duration, and averaging methods.
• Frequency weighting and signal processing for hand-transmitted vibration (to obtain representative vibration magnitude values).
• Data reduction, expression of results (e.g., r.m.s. vibration values) and required reporting format for test results and conditions.
• Requirements intended to allow reproducible, comparable type-test results between different laboratories and tool models.

Typical use and users

Used by tool manufacturers for type testing and product development, independent testing laboratories for conformance and comparative testing, occupational health and safety professionals assessing tool vibration emissions, and standards bodies referencing measurement procedures. It is mainly a laboratory (type-test) procedure rather than an in-field workplace measurement method.

Related standards

Part of the ISO 8662 series (other parts cover grinders, chipping hammers, impact drills, pavement breakers, polishers, etc.). ISO 8662-9 (1996) has been superseded/replaced by later ISO test-method standards in the ISO 28927 series (notably ISO 28927-6:2009 for certain impact tools and related parts of ISO 28927/ISO 8662 updates). National adoptions (BS EN, DIN EN, SS-EN, UNE-EN, etc.) mirror the international editions.

FAQ

Q: What is this standard?

A: BS EN ISO 8662-9:1997 is the British/European adoption of ISO 8662-9 (Edition 1, 1996). It defines a laboratory test method to measure vibration levels at the handles of hand-held rammers.

Q: What does it cover?

A: It covers instrumentation, mounting, test conditions, measurement axes, data processing (including frequency weighting) and reporting procedures to determine hand-transmitted vibration magnitudes for rammers under specified conditions. It is intended for type testing and comparison of tool models.

Q: Who typically uses it?

A: Tool manufacturers, independent test laboratories, occupational health professionals, and standards bodies use it for product evaluation, comparative testing and to provide vibration-emission data for exposure assessments.

Q: Is it current or superseded?

A: The ISO 8662-9:1996 / BS EN ISO 8662-9:1997 edition has been withdrawn and is superseded by later ISO test-method standards (ISO 28927 series and related parts). The ISO record indicates withdrawal and replacement by newer methods. Users should refer to the ISO 28927 series and the latest national adoptions for current test methods.

Q: Is it part of a series?

A: Yes — it is one part of the ISO 8662 series (measurement of vibrations at the handle) which includes multiple parts for different tool types; that series has been updated and consolidated in parts of the ISO 28927 series.

Q: What are the key keywords?

A: Rammers, hand-transmitted vibration, vibration at handle, hand-held power tools, test method, ISO 8662-9, BS EN, measurement, frequency weighting, type testing.
