Foreword Codeofchina.com is in charge of this English translation. In case of any doubt about the English translation, the Chinese original shall be considered authoritative. This document is developed in accordance with the rules given in GB/T 1.1-2020 Directives for standardization - Part 1: Rules for the structure and drafting of standardizing documents. This document is Part 4 of GB 8965 Protective clothing. The following parts of GB 8965 have been issued: ——GB 8965.1-2020 Protective clothing - Flame retardant protective clothing; ——GB 8965.2-2022 Protective clothing - Protective clothing for welders; ——GB 8965.3-2022 Protective clothing - Clothing to protect against molten metal splash; ——GB 8965.4-2022 Protective clothing - Arc flash protective clothing. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. The issuing body of this document shall not be held responsible for identifying any or all such patent rights. This standard was proposed by and is under the jurisdiction of the Ministry of Emergency Management of the People's Republic of China. Introduction In the working environment, the typical forms of flame and thermal damages include direct contact with flame, contact with flame and high-temperature solid during the welding, contact with all kinds of splashed molten metal, and thermal damage caused by electric arc discharge. Different flame and thermal damages have different action forms and characteristics, so different demands are put forward for body protection, and the protective clothing is divided into different types. On the basis of considering the application requirements and technical status of different types of flame and thermal damage protection products at home and abroad, this document specifies the technical requirements for the main types of protective clothing. The prepared GB 8965 series product standards will be composed of four parts. ——Part 1: Flame retardant protective clothing, Aiming to specify the technical requirements of protective clothing used in place with open fire, send-out spark, flammable material or exposed to flashover risk. ——Part 2: Protective clothing for welders, Aiming to specify the technical requirements of protective clothing used in welding and related working places. ——Part 3: Clothing to protect against molten metal splash, aiming to specify the technical requirements of protective clothing used in metal smelting and casting places and other places exposed to molten metal splash risk, so as to avoid or reduce the damage caused by molten metal to operators. ——Part 4: Arc flash protective clothing, aiming to specify the technical requirements of protective clothing that may suffer from transient arc energy and thermal damage in protective electrical and related working places. Protective clothing - Arc flash protective clothing 1 Scope This document specifies the requirements, marking and packaging and describes the test methods of arc flash protective clothing used in electrical and related working places.

[Source: GB/T 38302-2019, 3.3] 3.6 arc thermal performance value; ATPV energy value indicating that the energy incident on the material has a 50% possibility of causing enough heat to pass through the test sample and leads to second-degree burns according to the Stoll curve Note 1: The arc thermal performance value is one of the indicators to reflect the arc protective performance of materials, expressed in cal/cm2. Note 2: The conversion equation of arc hazard energy unit from English unit to metric unit is 1cal/cm2 = 4.19J/cm2. 3.7 breakopen reaction (phenomenon) in which one or more hole(s) are formed in the material, the thermal energy may pass through the material via the hole(s) Note: In case of a hole with an area greater than 1.6cm2 or a length greater than 2.5cm in any direction, the sample is considered to be broken. A single yarn crossing an opening or hole does not affect the evaluation result of hole size. During the sample test of multi-layer flame-retardant materials, the sample shall not be regarded having been broken until all layers are broken. During the test of multi-layer sample, if some layers are flammable, when these flammable layers are exposed, the sample is considered to be broken. 3.8 breakopen threshold energy EBT energy value indicating that the energy incident on the material has a 50% possibility of causing material breakopen Note: The breakopen threshold energy is one of the indicators to reflect the arc protective performance of materials, expressed in cal/cm2. 3.9 arc rating protective performance of materials when exposed to arc release Note: The arc rating is determined by the ATPV or EBT (whichever is lower) of the material (see Table 1), which is used to define the arc protective performance grade of the material.
