This document applies to the design, manufacture and inspection of leak sealing tools used to handle hazardous chemical leakage incidents during fire rescue and emergency response. 2 Normative references The contents of the following documents constitute indispensable provisions of this document through normative references. For dated references, only the edition cited applies. For undated references, the latest edition (including any amendments) applies. GB/T 528 Rubber, vulcanized or thermoplastic — Determination of tensile stressstrain properties GB/T 1689 Rubber, vulcanized — Determination of abrasion resistance (Akron machine) GB/T 3512 Rubber, vulcanized or thermoplastic — Accelerated aging and heat resistance test — Hot air method GB/T 9969 General principles for instruction manual of industrial products GB/T 10125 Corrosion tests in artificial atmospheres — Salt spray tests GB/T 10686 Test method of explosionproof performance for copper alloy tools GB/T 12007.7 Determination of gel time of epoxy resins 3 Terms and definitions The following terms and definitions apply to this document. 3.1 leak sealing tools Emergency tools consisting of one or more types of devices used to quickly seal gas or liquid leaks caused by holes, cracks, etc., occurring in equipment such as containers (e.g., tanks), pipes, valves and flanges. 3.2 explosionproof leak sealing tools Leak sealing tools made of materials that do not produce friction sparks or impact sparks, used to seal leaks of flammable and explosive media. 3.3 removable leak sealing tools Leak sealing tools used in conjunction with fastcuring sealing compound or material containing compound, which can be removed within a relatively short period after successful sealing, after which the cured sealing compound or material continues to provide sealing without leakage of gas or liquid. 3.4 bundle leak sealing tools Leak sealing tools that use a combination of strapping modules, tensioners (hydraulic or mechanically assisted), ropes/cords, locking blocks or hinged clamps, etc., to wrap, tighten and lock around a leaking part of equipment such as tanks or pipes, creating an annular pressure seal for rapid response to leaks of varying locations and dimensions. 3.5 pipe leak sealing tools Leak sealing tools with a tubular structure composed of a rigid outer shell and a flexible inner sealing layer, which apply circumferential pressure to the outer wall of a pipe by tightening bolts, causing the inner layer to deform and fit against the leaking area to seal the leak. These tools are used for rapid sealing of leaks on the outer wall of lowpressure fluid pipelines. 3.6 injection leak sealing tools Leak sealing tools that clamp a dedicated fixture onto the leak opening and lock it, then inject sealing compound into the cavity of the fixture until it is filled, thereby closing the leak opening. 3.7 adhesive leak sealing tools Leak sealing tools that rapidly press a contoured component, precoated with sealing compound, against the leak opening by mechanical pressure or tightening. After the compound has cured, the leak is sealed. 3.8 leak sealing tools by magnetism Leak sealing tools made of highstrength magnetic materials that, during operation, adhere to the leak opening or its vicinity. Using magnetic force (optionally assisted by other means) to press a sealing element against the leak, these tools are suitable for rapid gas or liquid leakage sealing of largediameter components such as steel containers (tanks), pipes and valves. 3.9 inflatable leak sealing tools Leak sealing tools that seal a leak by inflating a bladder, causing it to expand, relying on the deformation of the inflated body itself or constrained backpressure. NOTE: These include external sealing bags that wrap and tie around a leaking pipeline, internal sealing bags that are inserted into a pipeline and inflated to create a tight fit, and smallhole sealing guns that inject an expandable body into a small hole or crack to fit against the leaking area. 3.10 nominal sealing pressure Under specified applicable conditions (e.g., medium, temperature, pipe diameter), the standard value of the maximum static pressure of the leaking medium that a leak sealing tool is designed to withstand while maintaining an effective seal. 3.11 nominal sealing force Under specified applicable conditions (e.g., medium, temperature, pipe diameter), the standard value of the design force that a leak sealing tool must apply to the leaking area to achieve an effective seal. 4 Classification and model 4.1 According to the main material, leak sealing tools are classified as: a) Ordinary type: leak sealing tools used for sealing leaks in nonflammable or nonexplosive leakage sites; b) Explosionproof type: leak sealing tools used for sealing leaks in flammable or explosive leakage sites.
