Center Certification & Testing International
Project Introduction
With the rapid development of my country's auto industry, the VOC emissions of automotive interior materials are increasingly concerned by people. Environmental protection, health and quiet interior space has always been the eternal goal of the automotive industry. The total carbon volatilization test is a measurement of the total carbon volatilization (total organic matter volatilization) of the car interior by instrument analysis.
Pretreatment
The samples should be transported and stored in aluminum coated polyethylene bags; sampling should be carried out directly after the samples are received, the delivery time and sampling time should be fixed; natural compounds (such as cotton, wood, leather, wool) are dried with calcium chloride for 24 hours , Other substances do not need to be processed, but should be broken into small pieces before weighing.
sampling
The material shall be marked and sampled through the entire cross-section of the sample, and the sample shall be broken into small pieces greater than 10 mg and less than 25 mg. Note that the small pieces cannot be heated. If necessary, another sampling preparation method can be specified on the drawing or in the technical conditions of supply, but it must be marked in the description of the sampling result. Organic substances attached to metal parts, such as paint and adhesive materials, must be mechanically removed before weighing.
Weighing
Generally weigh 2g samples in 20ml headspace bottles (at least 3 bottles per sample). However, the specific sample size is based on the guarantee that the remaining space on the top layer is 5ml, such as sponges, foams and other large and light substances.

Wireless keyboard TELEC certification is a mandatory certification in Japan for wireless transmission equipment, with the full name being Technical Standards Conformity. This certification is implemented in accordance with Japan\'s Radio Law, aiming to ensure that wireless keyboards and other wireless devices comply with the technical standards and regulatory requirements of the Japanese market.
If a company is planning to export wireless keyboards to Canada, then ISEDIC certification is definitely a key focus you need to pay attention to! ISEDIC certification is a mandatory requirement of Industry Canada for wireless devices, and products that have not been certified will not be able to enter the Canadian market.
The TELEC certification for children\'s watches is a necessary condition for this product to enter the Japanese market. TELEC (Telecom Engineering Center) certification is a mandatory certification for wireless equipment in Japan, aimed at ensuring that the equipment complies with Japanese radio regulations.
