MOC 2514-2564 is the industrial product standard for “emulsion paint that reduces heat from sunlight” in Thailand, which specifies what type of house paint can be called heat-resistant or heat-reflective. This standard was announced in the Royal Gazette on September 8, 2021, as a revised version of MOC 2514-2553. Simply put, if a paint can claims to be heat-resistant but does not have this number, no one can certify that it is true.
What is MOC 2514-2564 and why is there this standard?
MOC 2514-2564 is a technical specification established by the Office of Industrial Standard (TISI) for emulsion paints that claim to reduce heat from sunlight, to provide consumers with a common benchmark for comparison, rather than relying solely on the advertising claims of each brand. Before 2010, the Thai paint market had no such benchmark; anyone could write “heat-resistant” on their can. The problem was that consumers had no way of knowing how a 1,000 baht paint differed from a 3,000 baht paint.
Who pushed for this standard?
The first standard, MOC 2514-2553, was initiated by Beger, a paint company that collaborated with the Ministry of Industry to promote and draft the standard for heat-reflective emulsion paint for the first time in Thailand, which has become a benchmark used by many paint companies to this day. The starting point of this matter came from the product BegerCool UV Shield which was the first product that Beger used to define the term heat-reflective paint in the Thai market.
How to check MOC 2514-2564 before buying, in 3 steps
You can check from standing in front of the shelf in the store to verifying official information, with accuracy increasing in order.
- Look at the can label It must clearly state “MOC 2514-2564”, not just the words cool, heat-resistant, heat-reflective, or heat shield, which are marketing terms that have no regulatory control. Anyone can write them.
- Check the manufacturer’s website Brands that truly meet the standard often have a page listing their MOC certifications for verification, such as Beger paint industry standards overview
- Verify the license directly with TISI. TISI has an online license database that allows you to check which factories have been granted licenses to produce products according to standard number 2514-2564. This step is the most accurate because it is official data that cannot be forged.
4 warning signs on paint labels
Even if you see the word standard on the can, there can still be cases that do not match what is understood. Pay attention to these 4 points.
| Visible Signals | True Meaning |
|---|---|
| States “tested according to MOC 2514-2564” but does not have the MOC mark. | The submission of samples for testing and passing is different from obtaining permission to display the Thai Industrial Standards Mark (TIS). The latter requires passing a factory inspection as well. |
| Referring to TIS number 2514-2553 | is an old standard; the current version is 2514-2564. |
| Displaying the % value of heat reflection without specifying the measurement method | The value SRI and the value of solar radiation reflection are different values, so they cannot be directly compared across types. |
| Displaying other TIS marks in the context of heat-reflective colors | such as TIS 272-2564, which is a general-purpose emulsion color, does not imply that it is a standard for heat reduction. |
What does this standard specify?
The standard specifies both the properties of heat reflection, the basic properties of color film, and safety from hazardous substances, with the criterion used to determine whether “it can actually reduce heat” being the solar radiation reflection value.
| Topics controlled by the standard | Key points |
|---|---|
| Solar radiation reflection value | The main criterion used for judgment, measured in a laboratory according to the methods specified by the standard. |
| Minimum criteria that must be passed | The standard sets the minimum values that products must achieve. Manufacturers who do not meet the criteria will not receive permission to display the Thai Industrial Standards Mark (TIS). |
| Classification / Quality grade | Classified according to the criteria in the standard, which is a different set from “Grade” used by manufacturers on cans |
| Film Color Properties | Durability, adhesion, and basic properties of emulsion paint |
| Hazardous Substances | Limits on heavy metals and substances harmful to users |
| Labels and Marks | Information that must be displayed on the packaging |
How is it tested?
Testing uses UV-Vis-NIR spectroscopy to measure the reflectance of the paint film in a wavelength range covering sunlight. Samples are prepared as test sheets, such as spraying paint onto a glass sheet measuring 8 × 8 centimeters, and then measured. A key point that people often misunderstand: this standard measures the reflectance of the paint film, not how many degrees cooler the house becomes. These two matters are related but are not the same number. Read the difference at How many degrees can house paint reduce temperature? In Thailand, there is a central agency that provides testing according to this standard, such as the National Science and Technology Development Agency (NSTDA), which specifically offers services to find the reflectance of solar radiation.
How does TIS 2514-2564 differ from other paint standards?
A can of house paint can have multiple standards at the same time, and each control number pertains to different matters. Do not assume that the TIS mark means it is heat-resistant paint.
| Standard Number | Name | What it controls |
|---|---|---|
| TIS 2514-2564 | Emulsion paint that reduces heat from sunlight | Reflectance of solar radiation, the decisive factor for whether it is heat-resistant paint or not |
| TIS 2321-2564 | Weather-resistant emulsion paint | Sunlight and rain resistance of the paint film |
| TIS 272-2564 | General-purpose emulsion paint | Basic properties of general water-based paint |
| TIS 1123-2555 | Primer paint for masonry work | Properties of primer paint |
High-grade exterior paint typically meets both TIS 2514-2564 and TIS 2321-2564 simultaneously, as it reflects heat alone, but if the paint film deteriorates quickly, it is of no long-term benefit.
SRI value and solar reflectance are not the same.
In the specifications of some products, you will see the value SRI (Solar Reflectance Index) according to ASTM E1980, which is an index that combines both reflectance and heat emission. This is different from the solar reflectance value used in TIS 2514-2564. When comparing two brands, you must compare the same type of value only.

FAQ Frequently Asked Questions about TIS, Heat-reducing paint standards
Q1: What is TIS 2514-2564?
A1: TIS 2514-2564 is the industrial product standard for heat-reducing emulsion paint from sunlight in Thailand, announced in the Royal Gazette on September 8, 2021, used to define which types of house paint can be called heat-reducing paint.
Q2: How does TIS 2514-2564 differ from TIS 2514-2553?
A2: TIS 2514-2553 is the first standard announced in 2010, while TIS 2514-2564 is the revised version currently in use. The number after the dash indicates the year of the Buddhist calendar when it was announced, not a product code.
Q3: Can paint labeled as heat-reducing but without TIS 2514-2564 be used?
A3: Yes, it can be used, but there is no central agency certifying that it reduces heat as claimed. The term heat-reducing or cool is a marketing name without regulatory requirements, unlike the standard number that must pass testing and receive a license.
Q4: Where can I check which brands have TIS 2514-2564?
A4: You can check from the online licensing database of the Industrial Product Standards Office (TIS) by searching with the standard number 2514, which will display the list of factories that have received the license.
Q5: What is the difference between “passed testing according to TIS” and “received TIS certification”?
A5: Passed testing means that samples were sent for measurement and met the criteria, while receiving TIS certification requires obtaining a license from TIS, which includes an assessment of the factory’s quality control system. A label stating only that it has passed testing does not equate to being certified.
Summary
TIS 2514-2564 is the dividing line between “claimed heat-resistant paint” and “proven heat-reducing paint,” as it is the only standard in Thailand that systematically defines the method for measuring solar radiation reflection. Before deciding to purchase exterior paint, look for this standard number on the label alongside TIS 2321-2564 and verify the license with the Thai Industrial Standards Institute (TISI) for added safety rather than relying solely on advertising claims.
