Standards this line is built to
The designations below are cited by the products on this page. A specification is written in these, not in product names, so each one is set out with what it governs. Progress Horizon Trading supplies this line as an authorized distributor across Saudi Arabia.
ASHRAE 70
The method of testing air outlets and inlets: how the performance data for a grille or diffuser is produced.
AMCA 500-D
The laboratory method for testing dampers: air performance and, critically, leakage. Leakage class is what a smoke control or energy calculation depends on.
EN 12238
Aerodynamic testing of air terminal devices for mixed-flow applications: the data behind a diffuser's selection tables.
SMACNA HVAC Duct Construction Standards
The North American reference for how ductwork is built: gauge, reinforcement and sealing against pressure class. What a duct submittal is checked against.
EN ISO 5219
Laboratory aerodynamic testing of air terminal devices: how a diffuser or grille's throw and pressure drop are established.
AMCA 500-L
The laboratory method for testing louvres: pressure drop and water penetration, which decide whether an intake louvre keeps weather out at design airflow.
AMCA 511
The certified ratings programme for air control devices: dampers and louvres carrying a verified rather than a claimed rating.
EN 13030
Rain penetration testing for louvres: how much water gets past at a given face velocity.

ASHRAE 62.1
Ventilation for acceptable indoor air quality: the outdoor air rates a building has to deliver.
AAMA 2605
The highest-performance class of organic coating for aluminium extrusions, specified where colour and gloss have to survive years of sun.
