Odor and smell laboratory construction technical specifications
1 scope of application
This standard specifies the stench olfactory laboratory location, layout and internal design and other technical requirements.
This standard applies to the construction of foul smell laboratory.
2 Normative references
This standard references the following documents in the terms. For undated references, the effective version applies
This standard.
GB/T 14675 air quality malodor three points comparison Odor bag method
Architectural Design Code of Science Laboratory
3 Terms and definitions
The following terms and definitions apply to this standard.
3.1 foul odor
All odorous gases that irritate olfactory organs cause unpleasant feelings and damage the living environment.
3.2 foul smell laboratory olfactory laboratory
Smell smell and smell were measured by three-point comparative smelly bag method, olfactometer determination method, malodour strength determination method and other methods
Of the laboratory, mainly for sample preparation equipment, sample preparation, olfactory determination and recovery of the smell.
3.3 Odor concentration odor concentration
Dilution factor for serial dilution of odorous samples to odor threshold with odorless air.
3.4 transfer window delivery window
A window used to pass samples in malodour tests.
3.5 olfactometer
In the determination of malodour, the odor sample is diluted with odorless air at a predetermined rate and passed to the instrument of the sniffer.
3.6 sniff table sniff table
Sightholder for malodour determination of the workbench.
3.7 sniff position sniff position
Opaque partition separated by an opaque partition into separate olfactory spaces.
4 new laboratory site
4.1 foul smell Laboratory should be far away from odor sources and noise sources, as adjacent to other laboratories, should be effectively isolated, and set
Set independent access.
4.2 foul smell When the site is located in the laboratory, it is necessary to measure the odor concentration of the air outside the foul smell building laboratory,
The maximum concentration should be less than 10.
5 laboratory layout
5.1 Stench Olfactory Laboratory shall have a sampling preparation room, sample preparation room, three functional areas sniffing chamber, equipped with olfactory instrument
Laboratory to be set olfactory pump room. Conditional laboratory can be additional lounge. The layout of the functional areas should be concentrated and compact
Clear, easy to contact, do not interfere with each other. The foul odor laboratory layout can refer to Figure 1.
Figure 1 smelling smell laboratory layout diagram
5.2 Stench Olfactory Laboratory's functional area and main functions. Sampling preparation room for the storage of sampling equipment, sampler prior to use
Preparation, after the determination of the sample processing, sampling equipment cleaning; sample preparation room for the determination of equipment storage, sample short-term deposit
Release, odorless air preparation, sample preparation, etc .; sniffing chamber for sniffing samples sniffing identification; lounge for sniffers to provide air
Clean rest environment, alleviating the sense of smell fatigue.
5.3 Sample preparation rooms can be shared with other laboratories, but need to meet the laboratory's internal design (6) requirements. Sample with
Room should be adjacent to the sniffing chamber, and set the transfer window. Transmission window length of not less than 0.60 m, a height of not less than 0.40 m,
Refer to Figure 2 design.

6 laboratory interior design
6.1 Construction and Decoration
6.1.1 Sampling preparation room, sample preparation room use area of not less than 8.0 m2, sniffing room use area of not less than 12 m2, with
Smell room smell olfactory use of not less than 17 m2. Indoor clear height of not less than 2.4 m.
6.1.2 laboratory interior walls, doors and windows to be tasteless, low-absorbent material, the floor laying tasteless, low-absorbent
Surface material. Olfactory pump room should be effective noise.
6.2 Internal facilities
6.2.1 Sampling preparation room The internal facilities include a test bed, a shelf, a sink, a fume hood or a mechanical ventilation device. The layout may be
Test map 3. Sample preparation room interior facilities include a laboratory bench, racks, cabinets, layout can refer to Figure 4. Sniff room inside
Facilities include sniffing table, chairs, layout can refer to Figure 5. Laboratory with olfactory instrument should also increase the olfactory instrument test bed, cloth
Bureau can refer to Figure 6. The above facilities are tasteless, low adsorption material.

6.2.2 Test bench width of not less than 0.75 m, sample preparation laboratory bench total length of not less than 1.5 m, sample preparation room bench
The total length of not less than 4.0 m. The height of the sniffing platform is 0.80 m, separated by a partition into 6 independent sniffing positions, each sniffing
Bit length of not less than 1.0 m, width of not less than 0.50 m, baffle height of not less than 0.30 m. Olfactory Taiwan's design can refer to the map
Figure 7 sniffing platform design schematic
6.2.3 Sampling preparation room and sample preparation room configuration of experimental equipment with reference to GB/T 14675 related requirements.
6.2.4 The indoor noise level of the olfactory room shall be less than 45 dB (A); the temperature fluctuation in the room during the test shall not exceed ± 3 ℃.
6.3 air purification and regulation
6.3.1 Odor Smell Laboratory should be equipped with ventilation and air purification devices to ensure that the laboratory air odor.
6.3.2 Odor Smell Laboratory temperature range should be between 17 ~ 25 ℃, relative humidity range should be between 40 to 70%.
7 Safety and protection
7.1 Vials and other fragile experimental equipment storage should be set "fragile" safety signs.
7.2 Sampler storage area should distinguish between clean area and work area, and set the safety mark.
7.3 Waste sample handling must be done in a fume hood.
7.4 Other requirements refer to JGJ 91 implementation.
