Feb 24, 2025 · A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa. 5, 6, 7 VOCs are sometimes categorized by the ease they will be emitted.

Aug 13, 2024 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

Sep 6, 2024 · The Danish Indoor Climate Label includes requirements on Emission testing for VOC, SVOC, carcinogenic compounds and LCI compounds according to EN 16516 and odour testing according to ISO 16000-28 (acceptance). Below table shows three classes for TVOC and formaldehyde criteria.

Feb 24, 2025 · Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors.

EPA’s AIM Rule includes national-level labeling requirements at 40 CFR 59.405. AIM products must be labeled with: Generally, state and local VOC labeling requirements follow the National AIM rule. However, some rules require additional labeling for certain categories of coatings.

Indoor Climate Label, Denmark Special VOC related label for several product groups (construction products, furniture, …). Emissions evaluation looks only at those VOC that are listed in a Danish database with irritation threshold limits ("VOCBASE"). Time (in days) is calculated when ½ of each irritation threshold is reached in a model room.

Sep 6, 2024 · Volatile Organic Compounds (VOC) are contained in various products and due to their volatility, they can be released from these products into indoor air. VOC may lead to health risks when a significant volume is set free.

Feb 13, 2018 · Volatile organic compounds (VOCs) are organic chemical compounds which can quickly evaporate to air due to their high vapour pressure and low boiling point. Common VOCs include ethanol, formaldehyde, benzene, toluene and xylene. VOCs are of concern to both indoor air quality and outdoor quality.

Jun 28, 2020 · 最近做了很多目标检测相关的任务，因为任务有时候是客户自己标注的xml格式，需要转换成yolov3使用的txt格式，即一行中包含类别信息和位置信息的模式，这一转换我们通常是使用官方的voc_label.py这个程序完成的，我们先来看一下xml的标注标注格式：（已经熟悉的可以直接跳到后面） 再看一些yolov3需要使用的txt格式的标注数据. 下面是两种数据格式的官方转换代码voc_label.py. 以上是对官方代码的解析，非小白可以忽略！ 以上的代码中有一处需要手动修改 …

Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates and ammonium carbonate, which participates in atmospheric photochemical reactions, except those designated by EPA as having negligible photochemical reactivity 2.
