ISO 28927-13:2022

Overview

ISO 28927-13:2022 specifies a laboratory test method for measuring vibration emission at the handle of fastener driving tools (nailers, staplers, pin drivers). It is a type-test procedure for establishing the vibration value of hand‑held portable power tools operating under specified load conditions. The standard applies to pneumatic and other drive types and to actuation modes such as single sequential, contact actuation, contact actuation with automatic reversion, and continual contact actuation. Full sequential mode is excluded from the main procedure (informative guidance for those tools is provided in Annex C).

Key topics and technical requirements

• Measurement focus: vibration at the handle (hand‑transmitted vibration) using frequency‑weighted, root‑mean‑square (r.m.s.) acceleration values and combined three‑axis totals.
• Three‑axis & hand positions: measurements in three orthogonal axes and at defined hand positions to represent realistic grip locations.
• Actuation modes: defined procedures and integration times for single sequential, contact and continual contact actuation; special guidance for full sequential tools in Annex C.
• Instrumentation: requirements for accelerometers/transducers, mounting and fastening, mechanical filtering, frequency‑weighting filters, calibration of the measurement chain and auxiliary equipment.
• Test conditions: specification of attached equipment, workpiece conditions, operating parameters, operator influence and repeatable test procedures.
• Reporting & verification: declared vibration emission values, test report content (model report in Annex A), and uncertainty determination (normative Annex B).
• Use limits: the Introduction notes that type‑test values represent the upper quartile of typical use and recommends caution when extrapolating to real workplaces (values below 2.5 m/s² should be treated carefully for workplace estimation).

Practical applications

• Manufacturers: to determine and declare handle vibration emission for product data sheets and conformity documents.
• Test laboratories: to perform repeatable, comparable type tests for product certification and R&D.
• Safety and occupational health professionals: to compare tools for procurement and to assess relative vibration exposure risk.
• Design and R&D teams: to evaluate vibration mitigation measures (ergonomics, damping, tool design).
• Regulatory/compliance officers: to verify declared values and support conformity assessment under national/international rules.
