The bus, coach and vehicle air-conditioning systems manufacturer increased its rating from Bronze to Silver after a successful audit by IRIS during the renewal of its certification. In achieving Silver, the highest quality performance level, only introduced in 2020, Hispacold has demonstrated that it can meet the most stringent and respected rail industry standards.

In 2016, Hispacold gained its first certification from IRIS (International Railway Industry Standard), a quality assurance rating system for performance, initiated by UNIFE (The European Rail Industry) and backed by the major rail operators, manufacturers and system integrators. The rating system aimed to ensure compliance with international standards of quality and was developed in response to a growing demand for reliablity and for quality capacity management in the rail sector.

The IRIS Certification programme awards businesses in the global rail industry with performance levels which reflect their commitment to offering quality. Bronze and Silver are currently the two levels available for audited companies to achieve. While IRIS-certified companies have already demonstrated their strong business management systems, earning the Silver level indicates that the organisation has demonstrated the ability to meet even more prestigious benchmark standards.
