According to GB/T 15706, this part belongs to class B standard. The terms of this section may be supplemented or modified by category C standards. For machines designed and constructed in accordance with Class C standards, if the provisions of Class C standards are inconsistent with Class A or Class B criteria, Using Class C standards. Mechanical safety airborne emissions of harmful substances Evaluation Part 6. Measuring the outlet with conduit A Test - bed Method for Quality Separation Efficiency of Air Purification System1 ScopeThis part of GB/T 25749 specifies the quality separation of an air purification system with a conduit outlet at a given operating condition Efficient test bench method. The method is suitable for the purification of airborne aerosols (smoke, dust, soot, fine mist), steam or gas systems. The quality separation efficiency of the air purification system used for the intended use is measured and can be used to. a) Evaluation of air purification system performance; b) Improved assessment of air purification systems; c) Comparison between air purification systems; d) classify the air purification system according to the quality separation efficiency; e) Determine the technical level of the same intended use of the air purification system according to the quality separation efficiency.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. ISO 12100 Mechanical Safety Design General Risk Assessment and Risk Reduction (Safetyofmachinery-General principlesfordesign-Riskassessmentandriskreduction3 terms and definitionsISO 12100 and the following terms and definitions apply to this document. 3.1 Quality separation efficiency separationefficiencybymass ηs < Air purification system> The pollutant mass (m3) filtered by the air purification system for a given contaminant at a given time Into the air purification system of pollutant mass (m1) ratio. Note. The percentage of the mass separation efficiency of the air purification system can be expressed as follows. ηs = m3 m1 × 100% (1)4 principleThe principle of the measurement method is to operate the air purification system on the test bench under specified conditions and to determine the upstream and lower air purification systems The quality of the test substance. The test substance may be an actual contaminant or a substitute, preferably a low toxicity and consistent with the target of the measurement method. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 25749.6-2012_English be delivered?Answer: Upon your order, we will start to translate GB/T 25749.6-2012_English as soon as possible, and keep you informed of the progress.
