This is because NOM and CRT certifications require local testing. Sample testing is necessary to verify that telecommunications equipment meets the specified criteria.<\/p>\n\n\n\n<p>These requirements are established by the Comisi\u00f3n Reguladora de Telecomunicaciones (CRT), an agency under the Official Gazette of the Federation (DOF). It was formed from the National Antimonopoly Commission (CNA) and the Agency for Digital Transformation and Telecommunications (ATDT). Previously, it was known as the Federal Institute of Telecommunications (IFT).<\/p>\n\n\n\n<p>Frequently asked questions regarding sample requirements for Mexico type approval include how many samples are required and what the criteria are. We will answer these questions thoroughly in this article.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is a Testing Sample?<\/h2>\n\n\n\n<p>The type approval certification process requires testing of telecommunications equipment, known as testing samples. This is especially important in countries that require local testing for the application.<\/p>\n\n\n\n<p>The testing sample will be based on compliance with applicable technical standards in that country. The type of testing and device features will determine the number and type of samples required.<\/p>\n\n\n\n<p><a href=\"https:\/\/media.narmadi.com\/en\/r\/5124\/local-testing-for-mexico-type-approval\/\">Local testing for Mexico type approval <\/a>is mandatory. Therefore, the sample requirements for Mexico type approval are necessary for NOM and CRT certification applications. We will discuss the quantity and requirements in more detail in another section.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sample Testing Process<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-2.webp\" alt=\"Sample Requirements for Mexico Type Approval 2\" class=\"wp-image-5133\" srcset=\"https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-2.webp 1200w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-2-300x169.webp 300w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-2-1024x576.webp 1024w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-2-768x432.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p>Sample requirements for Mexico type approval will be used to conduct several types of testing. The product&#8217;s features and the technical regulations governing it will determine the type of testing.<\/p>\n\n\n\n<p>The following types of testing must be performed:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>NOM Testing: <\/strong>A process to ensure the safety and quality of a product before it is marketed.<\/li>\n\n\n\n<li><strong>Radio Frequency (RF) Testing: <\/strong>This process is performed on devices that use radio frequencies to evaluate wireless signal transmission.<\/li>\n\n\n\n<li><strong>Safety Testing: <\/strong>Ensures that the device is safe for use with equipment and power adapters.<\/li>\n<\/ul>\n\n\n\n<p>The entire process will be conducted at local laboratories in Mexico. The CRT will determine the location of the sample testing based on each laboratory&#8217;s capabilities and availability.<\/p>\n\n\n\n<p>It should be noted that each laboratory has different capabilities and availability. Therefore, testing may be conducted at more than one laboratory. For example, RF testing may be conducted at laboratory A, but safety testing at laboratory B.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Many Samples Are Required?<\/h2>\n\n\n\n<p>The number of samples required for Mexico type approval when applying for NOM and CRT certification depends on the device&#8217;s features and the type of testing required. However, generally, three sample units are required.<\/p>\n\n\n\n<p>One sample is used for NOM testing, while the other two are used for RF and safety testing, respectively. Additional samples may be required if the product has more complex features.<\/p>\n\n\n\n<p>For example, an access point product with a DFS feature requires testing in a separate sample. Therefore, one additional sample is required in addition to the two required samples.<\/p>\n\n\n\n<p>The type of sample will be discussed with the relevant testing laboratory. Generally, for products requiring only NOM certification, only a normal sample is required. However, for products requiring both NOM and CRT certification, a combination of tested and normal samples is usually required.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Sample Requirements for Mexico Type Approval<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"675\" src=\"https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-3.webp\" alt=\"Sample Requirements for Mexico Type Approval 3\" class=\"wp-image-5134\" srcset=\"https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-3.webp 1200w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-3-300x169.webp 300w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-3-1024x576.webp 1024w, https:\/\/media.narmadi.com\/en\/wp-content\/uploads\/2026\/03\/Sample-Requirements-for-Mexico-Type-Approval-3-768x432.webp 768w\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" \/><\/figure>\n\n\n\n<p>Sample requirements for Mexico type approval refer to mandatory local testing requirements. <a href=\"https:\/\/media.narmadi.com\/en\/r\/5117\/applicant-for-mexico-type-approval\/\">Applicants for Mexico type approval<\/a> generally must submit two different types of sample conditions.<\/p>\n\n\n\n<p>The required sample conditions are a tested sample and a normal sample. Different types of testing require different types of samples.<\/p>\n\n\n\n<p>Generally, a normal sample is required for NOM and safety tests. Radiated samples are required for RF testing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Conducted sample<\/h3>\n\n\n\n<p>A conducted sample is required for RF testing, and therefore, it must be equipped with an RF cable or SMA connector. The cable and connector function to connect the device to the spectrum analyzer.<\/p>\n\n\n\n<p>The spectrum analyzer uses the sample to measure the required parameters. These parameters include frequency range, output power, bandwidth, and spurious emissions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Normal sample<\/h3>\n\n\n\n<p>A normal sample is required for NOM and safety tests. It is a commercial product that will eventually be marketed. A normal sample has not undergone any modifications.<\/p>\n\n\n\n<p>Some products are often equipped with RF or SMA connectors. If so, this sample can be used as a conducted sample.<\/p>\n\n\n\n<p>Normal sample testing will refer to applicable international standards, for example, Conformit\u00e9 Europ\u00e9enne (CE) or the Federal Communications Commission (FCC).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Ensuring Sample Compliance with Pre-Testing<\/h2>\n\n\n\n<p>Sample requirements for Mexico type approval are crucial. They determine whether certification can proceed to the document submission stage.<\/p>\n\n\n\n<p>Therefore, ensuring samples comply with applicable technical standards is mandatory. This can be achieved through pre-testing. However, not many certification services offer this service.<\/p>\n\n\n\n<p>Dimulti understands the impact if a sample fails the official testing phase. Therefore, we offer a pre-testing service to ensure your product meets the correct testing parameters.<\/p>\n\n\n\n<p>Your sample will be tested in our in-house lab before being submitted for official testing in Mexico. During pre-testing, we can check the frequency range, output power, and bandwidth parameters for RF testing.<\/p>\n\n\n\n<p>For bandwidth testing, our equipment supports frequencies ranging from 125 kHz to 8 GHz. Frequencies outside this range must be tested directly in an authorized laboratory.<\/p>\n\n\n\n<p>If any issues are discovered during pre-testing, we can detect them early and promptly correct them. This way, there will be no more failures during official testing.<\/p>\n\n\n\n<p>What about costs? Don&#8217;t worry, Dimulti&#8217;s pre-testing service is included in our service. Where else can you get this level of service without overspending?<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Understanding the sample requirements for Mexico type approval is crucial before applying.
