c) In case the test does not result in ignition using a test temperature of 960 ºC, the GWIT should be reported as follows: GWIT: >960/”thickness,” d) GWFI and GWIT values for varying thicknesses should be reported as follows: GWFI: 850/0.75-3.0; GWIT: 775/0.75-3.0. 4. Conclusions This paper has reviewed the performance of the glow-wire test, offering a general background and a comprehensive literature survey on assessing polymer characteristics and the impact of additives on fire resistance, accompanied by a discussion about the regulatory considerations and standards compliance. The addition of flame-retardant has been proven to significantly impact the fire resistance of polymer materials in specific compositions and configurations. The findings highlight how the glow-wire test evaluates a polymer's ability to resist ignition when exposed to overheated wires and assesses its capacity to self-extinguish, preventing the fire from spreading to other components. Results show that incorporating additives significantly improves fire resistance, although the degree of improvement depends on the material’s composition and thickness. These insights are crucial for developing fire -resistant polymer materials, particularly for applications in the electrical and automotive industries. Apart from that, non-compliance with GWFI and GWIT writing standards occurs due to a lack of information on the dimensions of the test specimen. In contrast, specimen dimension information is necessary because GWFI and GWIT can vary depending on the

specimen's thickness. Acknowledgments
