Core contents of the standard: First, scope of application specification, covering all categories of elevator traveling cables, control cables, power cables, connecting wiring harnesses, flat cables and round cables, applicable to the whole process of R&D, production, inspection and acceptance of elevator cables, forming a complete system with the mechanical and physical properties and electrical properties parts of the series standards; Second, core combustion test items, clarifying 7 core combustion performance test items: vertical combustion test, single vertical combustion test, bundled combustion test, smoke density test, halogen content test, toxicity index test, and fire resistance integrity test; Third, unified test method, standardizing the equipment requirements, environmental conditions, sample preparation, test steps, data calculation methods, and result judgment standards of each test to ensure the consistency and comparability of test results from different laboratories; Fourth, graded judgment standard, according to combustion performance, smoke density and toxicity index, the flame retardant performance of elevator cables is divided into three grades A, B and C, clarifying the selection requirements of cable flame retardant grades for different application scenarios. Elevators in high-rise buildings and public gathering places must use grade A flame retardant cables; Fifth, test report specification, unifying the content, format and data recording requirements of the combustion performance test report, clarifying the qualification criteria for test results, and providing a unified basis for product R&D, certification and acceptance.
