About Our Certifications
Tianjin Jiuding Yangguang HVAC Co., Ltd. — trading as Jiuding Radiator — manufactures steel panel and multi-column radiators under a documented, third-party-verified certification framework. CE conformity is established through 10 Declarations of Performance issued under EU Construction Products Regulation No. 305/2011 by HEATEST s.r.o. (Notified Body NB 2693, Czech Republic), covering both column and panel radiator ranges to EN 442-1:2014. For the UK market, independent thermal performance tests have been conducted by BSRIA Limited (Bracknell, UK) to BS EN 442-2:2014 — the same standard underlying CE conformity — providing third-party UK backing for seven column radiator models. Quality and environmental management systems are certified to ISO 9001:2015 and ISO 14001:2015 by Xingyuan Certification Centre (CNAS-accredited, IAF member), valid through June 2027. REACH/SVHC compliance is confirmed by SGS test report No. TSNEC2000446701. All CE-certified products achieve reaction-to-fire class A1. Jiuding also holds a Russian market conformity certificate and has exhibited at ISH 2026 (Frankfurt) and MCE Expocomfort 2026 (Milan) as a registered new exhibitor.
Note on UK Conformity
Jiuding does not hold a separately-issued UKCA certificate. UK market conformity is supported by BSRIA independent test reports (104719/1 and 105549/1), which provide third-party BS EN 442-2:2014 verification equivalent to the technical requirements of the UK building regulations pathway for heating products. The BSRIA route is the standard pathway used by manufacturers supplying the UK market post-Brexit.
ISO Quality Certifications
ISO 9001:2015 (Certificate No. 0350124030591R2M) and ISO 14001:2015 (Certificate No. 0350124E2038902M), both issued 2024-06-10, valid through 2027-06-09. Issued by Xingyuan Certification Centre Co., Ltd. (CNAS-accredited, IAF member).
REACH / SVHC Compliance
All CE-certified Jiuding products comply with REACH Regulation. SGS REACH/SVHC test report No. TSNEC2000446701 (2020-04-08) confirms no release of dangerous substances and is referenced in all 10 CE Declarations of Performance.
Reaction-to-Fire Classification
All CE-certified Jiuding radiators achieve reaction-to-fire class A1 (non-combustible) under EN 13501-1, as determined by VZLU TEST a.s. (Czech Republic), report P-VZLUTEST-068/23 (2023). Class A1 is required in many commercial and public-sector projects in Europe.
