Описание (английский):

La présente partie de l'ISO 14269 prescrit une méthode d'essai permettant de simuler le chauffage solaire en laboratoire et de mesurer l'énergie de rayonnement de chauffage émise par une source naturelle ou artificielle. La présente partie de l'ISO 14269 est applicable aux tracteurs et machines automotrices pour l'agriculture et la sylviculture équipés d'une enceinte d'opérateur.

Overview

ISO 14269-3:1997 specifies a laboratory and field test method to determine the effect of solar heating on operator enclosures of tractors and self‑propelled machines for agriculture and forestry. Part 3 of the ISO 14269 series records and simulates solar radiant energy so that air‑conditioning and ventilation performance can be evaluated under controlled and repeatable solar load conditions.

Key topics and requirements

Purpose: Record radiant heat energy affecting an operator enclosure during HVAC performance tests and simulate solar heating in the lab.

Field measurement:

Use a pyranometer placed near the enclosure; measure at 10 min intervals and average the readings for test reporting.
A measured average of 950 W/m² – 95 W/m² is identified as “normal” test conditions (as stated in the standard).
The pyranometer should meet the accuracy requirement given in the standard.

Laboratory simulation:

Lamps mounted in banks above the enclosure in a horizontal plane to simulate sun exposure.
The light bank area must extend 25% beyond the projected enclosure perimeter in all directions.
The light source spectrum shall have 45% or more of radiated energy above 700 nm to simulate solar heating effects.

Calibration and uniformity:

Calibrate simulated source with a pyranometer mounted on a horizontal plane close to the enclosure roof line (see standard for specified offset).
Measure at multiple points within the uniform intensity area (maximum spacing 1 200 mm) to ensure uniformity.
Adjust intensity to an average of 950 W/m² – 95 W/m² with no single reading more than 10% from the average.
Recalibrate every six months or when enclosure roof elevation changes.

Applications and users

Tractor and forestry machine manufacturers (OEMs) validating cab HVAC and thermal comfort performance.

Independent test laboratories performing repeatable solar load tests for product certification or comparison.

HVAC and enclosure designers assessing cooling capacity and air circulation needs under solar load.

Regulatory bodies and procurement teams defining test conditions for operator comfort and safety requirements.
