前文“《消防设施通用规范》GB 55036-2022学习——悬挂式干粉灭火装置竟然被禁用？”发布后，引发了较大的反响。
The previous article “General Code for Fire Protection Facilities” GB 55036-2022 Study – Suspended dry powder fire extinguishing device is actually banned? After the release, it caused a big response.
有朋友的说，超细干粉不是干粉，悬挂式干粉灭火装置不是干粉灭火装置，干粉灭火装置不是干粉灭火系统……这个么，只能用“白马非马”来解释。
Some friends said that ultra-fine dry powder is not dry powder, hanging dry powder fire extinguishing device is not dry powder fire extinguishing device, dry powder fire extinguishing device is not dry powder fire extinguishing system… This can only be explained by “white horses are not horses”.
笔者也早在 “变电站电缆层自动灭火系统是否能采用悬挂式超细干粉灭火装置（1）——什么是超细干粉灭火装置”一文中论证了这些问题，不再赘述。
The author has also demonstrated these problems in the article “Whether the automatic fire extinguishing system of the substation cable layer can use the suspended ultra-fine dry powder fire extinguishing device (1) – what is the ultra-fine dry powder fire extinguishing device”, and will not repeat them.
严格意义上讲，并没有“悬挂式超细干粉自动灭火装置”这种消防产品，正确的用词是“悬挂式干粉灭火装置”。也就是说俗称的“悬挂式超细干粉自动灭火装置”都属于悬挂式干粉灭火装置，且市场上悬挂式干粉灭火装置使用的都是超细干粉灭火剂。
Strictly speaking, there is no such fire-fighting product as “hanging ultra-fine dry powder automatic fire extinguishing device”, and the correct word is “hanging dry powder fire extinguishing device”. That is to say, the commonly known “hanging ultra-fine dry powder automatic fire extinguishing device” belongs to the hanging dry powder fire extinguishing device, and the hanging dry powder fire extinguishing device on the market uses ultra-fine dry powder fire extinguishing agent.
悬挂式干粉灭火装置被消防设施通用规范禁用，很可能只是规范的一个疏漏。因为同样是悬挂式灭火装置，对于气体灭火系统就没要求设置机械启动方式。具体见通用规范8.0.10条。
The fact that suspended dry powder fire extinguishing devices are prohibited by the general code for fire protection facilities is likely to be just an omission in the code. Because it is also a suspended fire extinguishing device, there is no requirement for a mechanical start mode for the gas fire extinguishing system. For details, see General Specification 8.0.10.
今天解决一个简单的问题—— Solve a simple problem today –
消防救援行业标准《超细干粉灭火剂》XF 578-2023中，对于ABC超细干粉灭火剂，要求灭火效能小于或等于150g/m3。
In the fire rescue industry standard “Ultrafine Dry Powder Fire Extinguishing Agent” XF 578-2023, for ABC ultrafine dry powder fire extinguishing agent, the fire extinguishing efficiency is required to be less than or equal to 150g/m 3 .
但一些地方标准或厂家宣传资料中，灭火效能值比行业标准低得多，有60kg/m3 、120kg/m3、130g/m3等。是否可执行地方标准？
However, in some local standards or manufacturers’ promotional materials, the fire extinguishing efficiency value is much lower than the industry standard, including 60kg/m, 120kg/m, 130g/m 3 3 3 , etc. Are local standards enforceable?
厂家的产品优于行业标准，这是完全可能的。但是，空口无凭，必须有型式试验检验报告为依据。
It is entirely possible that the manufacturer’s products are superior to the industry standard. However, there is no evidence for the air port, and there must be a type test inspection report as the basis.
笔者查了一些头部厂家的型式试验报告，灭火浓度的检测标准均为150g/m3。
The author checked the type test reports of some leading manufacturers, and the detection standard of fire extinguishing concentration is 150g/m 3 .
所以，如灭火浓度采用地方标准中小于150g/m3值，灭火能力根本没有保障。
Therefore, if the fire extinguishing concentration is less than 150g/m 3 in the local standard, the fire extinguishing capacity is not guaranteed at all.
较权威的中国工程建设标准化协会《干粉灭火装置技术规程》CECS 322:2012和一些地方标准都规定，设计灭火浓度应不小于1.2倍经权威机构认证合格的灭火浓度，通常为1.2*150=180g/m3。
The more authoritative China Engineering Construction Standardization Association “Technical Regulations for Dry Powder Fire Extinguishing Devices” CECS 322:2012 and some local standards all stipulate that the design fire extinguishing concentration should not be less than 1.2 times the fire extinguishing concentration certified by the authoritative organization, usually 1.2*150=180g/m 3 .
笔者核对了一些厂家宣传的全淹没灭火能力，基本是按行业标准150g/m3进行计算，实际工程设计中一般还要增加1.2倍的安全系数。
The author checked the total submerged fire extinguishing capacity advertised by some manufacturers, which is basically calculated according to the industry standard of 150g/m 3 , and the safety factor is generally increased by 1.2 times in the actual engineering design.
