ISO 4008-1-1980 rus PDF

Full title and description

Road vehicles — Fuel injection pump testing — Part 1: Dynamic conditions. International Standard ISO 4008-1:1980 specifies requirements for test benches and procedures used to evaluate fuel injection pumps under dynamic (operating) conditions. A Russian-language catalogue entry exists for this standard (Russian editions/translations are commonly made available by national bodies).

Abstract

This part of ISO 4008 defines the requirements and characteristics of test benches intended for calibration and dynamic testing of fuel-injection equipment for compression-ignition (diesel) engines, covering pumps delivering up to 300 mm3 per injection per cylinder at full load. It describes apparatus, measurement and accuracy requirements specific to dynamic test conditions.

Scope

Specifies the characteristics and required performance of test benches for dynamic testing of diesel fuel injection pumps (delivery measurement, instrumentation tolerances, test conditions and records). The scope is limited to benches suitable for pumps with delivery up to approximately 300 mm3/injection/cylinder at full load and focuses on dynamic (running) conditions rather than static measurement alone.

Key topics and requirements

• Definition of dynamic test conditions and test sequences for pump performance evaluation.
• Requirements for test-bench construction and hydraulic/mechanical interfaces (injector holders, supply piping, trapped volumes).
• Measurement system performance and accuracy targets for delivery measurement (limits on zero error, count error and overall measurement uncertainty).
• Instrument and calibration fluid conditions (temperature control, gauge tolerances and tachometer accuracy).
• Test record forms and reporting requirements to ensure repeatability and comparability of results.

Detailed measurement tolerances and procedural items are set out in the standard and complemented by the companion Part 2 (static conditions).

Typical use and users

Used by fuel injection pump and nozzle manufacturers, automotive OEM powertrain test laboratories, calibration and certification laboratories, heavy-vehicle service workshops performing bench calibrations, and national standards bodies producing translations or national adoptions.

Related standards

Mainly paired with ISO 4008-2:1983 (Road vehicles — Fuel injection pump testing — Part 2: Static conditions). Other related ISO documents referenced in the standard include standards on calibrating nozzles and fuel filter test methods (for example ISO 4010 and ISO 4020 as normative references).

FAQ

Q: What is this standard?

A: ISO 4008-1:1980 is an international standard that specifies requirements for test benches and methods to test fuel injection pumps under dynamic (operating) conditions.

Q: What does it cover?

A: It covers apparatus characteristics, measurement systems and accuracy tolerances, test sequences and record-keeping needed to assess pump delivery and performance while the pump is running (dynamic conditions). It is intended for pumps used on compression-ignition engines up to the stated delivery limit.

Q: Who typically uses it?

A: Pump and nozzle manufacturers, vehicle OEM test departments, independent test laboratories, calibration workshops and standards organizations that adopt or translate ISO documents.

Q: Is it current or superseded?

A: The 1980 edition (ISO 4008-1:1980, Edition 2) remains the published version; ISO indicates the standard has been subject to periodic review (it was confirmed/reconfirmed through review cycles). Users should check the ISO catalogue or their national standards body for the absolute current status before relying on it for compliance.

Q: Is it part of a series?

A: Yes — it is Part 1 (dynamic conditions) of ISO 4008; Part 2 (static conditions) is ISO 4008-2:1983. The two parts together cover dynamic and static aspects of fuel-injection-pump test benches.

Q: What are the key keywords?

A: fuel injection, pump testing, dynamic conditions, calibration, diesel, test bench, delivery measurement, ISO 4008.
