Описание (английский):

Defines only the requirements and characteristics of test benches. Applies to test benches suitable for calibration of fuel injection equipment for compression ignition engines requiring fuel delivery up to 300 mm^3/injection/cylinder at full load. This second edition cancels and replaces the first edition (1977).

Abstract

Overview

Key topics and technical requirements

The standard defines measurable dynamic parameters and test methods for fuel injection pump test benches. Key technical points include:

Scope: Requirements only for test bench design and performance to ensure correct pump calibration under dynamic conditions.
Speed stability: Mean driveshaft speed must remain within ±0.25% at speeds > 800 min‑1 and within ±2 min‑1 below 800 min‑1 for at least 1 minute under steady load.
Cyclic speed variation: Instantaneous speed variation at the driveshaft coupling must not exceed 1% peak‑to‑peak under design test conditions.
Mechanical stiffness limits:
- Driveshaft angular deflection under peak injection torque ≤ 0.02°.
- Coupling angular deflection under peak injection torque ≤ 0.10°.
Backlash and angular creep: No backlash in transmission between flywheel and coupling output; no angular creep when subject to torque reversals equal to twice peak injection torque.
Misalignment limits: Coupling alignment tolerance - radial ≤ 0.13 mm, angular ≤ 0.25 mm over 300 mm.
Flywheel requirement: Flywheel must store enough energy to supply the entire energy of one injection without transmission assistance.
Classification and graphs: Test benches are classified by output power, speed range and speed droop, and by maximum pump delivery and test speed; manufacturers present characteristics in standardized graphs.
Verification methods: Physical measurements (dynamometer), special pump‑simulating apparatus, and annexed procedures for stiffness and coupling testing.

Applications and users

ISO 4008-1:1980 is used by:

Test bench manufacturers specifying design and declared capabilities.
Fuel injection pump manufacturers validating pump calibration procedures.
Automotive OEMs, calibration labs, and aftermarket service centers that perform pump testing and adjustment.
Quality and conformity assessors who verify test‑bench compliance before accepting pump calibration data.

Practical uses include selecting or designing a test bench that will reliably reproduce pump dynamic loading, qualifying benches for specified pump types, and ensuring consistent calibration across different facilities.
