Full title and description

ISO 2787:1984 — Rotary and percussive pneumatic tools — Performance tests. This international standard specifies test methods, instrument requirements and reporting procedures to obtain repeatable and comparable performance data for rotary and percussive pneumatic tools (rotary air motors, impact wrenches, percussion drills, etc.).

Abstract

The standard defines the conditions and measurements for performance testing of pneumatic rotary and percussive tools, including power output, air consumption, rotational speed, torque, impact energy and blow rate, together with required test arrangements, calibration and ambient-condition recording to ensure comparable results across manufacturers and test laboratories.

General information

• Status: Published and confirmed (International Standard; edition confirmed in ISO reviews).
• Publication date: January 1984 (1984-01).
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 25.140.10 — Pneumatic tools.
• Edition / version: Edition 2 (1984). This edition cancels and replaces the first edition (1974).
• Number of pages: 16 pages (ISO bibliographic entry).

Scope

Specifies performance test methods for rotary and percussive pneumatic tools to determine and report no‑load and under‑load characteristics such as rotational speed, torque (starting, stall, dynamic), power output, air consumption, impact energy and blow rate. The standard sets test arrangement details (pressure measurement point, hose length recommendations), ambient condition recording, instrumentation accuracy and conversion/adjustment procedures so results are comparable between laboratories and manufacturers. Typical test pressure references and ambient conditions to be recorded are included.

Key topics and requirements

• Definitions and symbols for torque, power, speed and pneumatic terms used in testing.
• Specified test conditions and ambient‑condition recording (temperature, atmospheric pressure) and procedures to adjust measured values to reference conditions.
• Measurement of air consumption (no‑load and under‑load) and power output; requirements for calibrated instruments and measurement accuracy.
• Torque and speed measurement requirements for rotary air motors including starting, stall and running values; procedures for measuring impact energy and blow/impact rate for percussion tools.
• Pressure measurement location and hose recommendations (e.g., guidance to measure upstream of the tool and allowance for hose length to account for pulsations).
• Reporting format and information to be supplied with test results so data are repeatable and comparable (test setup, calibration status, instrument accuracy, test pressure).

Typical use and users

Used by pneumatic‑tool manufacturers for product specification and quality control, independent test laboratories for performance verification, procurement and technical purchasing teams for comparing tool performance, and standards committees or regulatory bodies referencing consistent test methods. It is aimed at engineers, test technicians and product developers working with rotary air motors and percussion pneumatic tools.

Related standards

Developed by ISO/TC 118 (Compressors, pneumatic tools and pneumatic machines) and related to earlier ISO 2787:1974 (this 1984 edition replaces the 1974 edition). Other ISO documents and sector standards on pneumatic equipment performance and test methods may be referenced for complementary test procedures.
