How to do the test report? Why do you need to do product inspection? Third-party testing institutions provide product testing services in various industries, and there are many cooperative laboratories across the country, mainly serving companies, enterprises, individual businesses, universities and scientific research.
Report qualification: CNAS, CMA, CAL, etc.
Testing costs: according to customer needs and experimental complexity, quotation
sample size: according to the samplesize to choose the sample or door-to-door
display style: electronic version
Testing cycle: 3-15 working days (expedited).
Scope and Purpose
This section applies to electrical and electronic equipment used in industrial environments and for which there are no specific product or product class immunity standards yet The frequency range of this section is from DC to 400GHz. Testing is not required at frequencies where immunity requirements are not specified. In the case of relevant specialized products or product class electromagnetic compatibility (EMC) immunity standards, product standards or product class standards will take precedence over this general standard in all aspects The environment included in this section is an industrial environment, including both indoor and outdoor aspects. The equipment involved in this section is pre connected to the power grid powered by high-voltage or medium voltage transformers, specifically designed for power supply of equipment in manufacturing plants or similar factories, as well as equipment intended to operate in industrial environments or close to industrial environments Equipment used in industrial premises has one or more of the following characteristics:
There is a power grid powered by commercial or medium voltage transformers, specifically designed to supply power to equipment in manufacturing plants or similar factories Industrial Scientific and Medical Equipment (ISM)
High capacity inductive or capacitive loads that are frequently switched on or off;
High currents and their accompanying strong magnetic fields.
The purpose of this section is to specify the immunity test requirements for equipment operating under continuous, transient, conducted, and radiated disturbances, as well as electrostatic discharge conditions.
When selecting immunity requirements for equipment in industrial environments, appropriate immunity levels should be ensured. However, these immunity levels are not Involving extreme situations that may occur in any location with a very low probability. The tests in this section do not include all electromagnetic disturbance phenomena, only those related to this section are considered This section specifies test requirements for each port considered Note 1: This section does not include safety considerations Note 2: In some special cases, there may be situations where the disturbance level exceeds the test level specified in this section. For example, an electrical appliance installed near the ISM equipment specified in GB4824 or a handheld transmitter used near the electrical equipment. In these situations, specialized mitigation measures may be necessary Note 3: Special mitigation measures may alter the industrial environment. Where it is indicated that the electromagnetic environment can be equivalent to residential, commercial, and light industrial environments through these measures, general standards or related product standards related to this environment should be adopted
Function of testing report:
1. Project bidding: Issue authoritative third-party CMA/CNAS qualification report
2. Online e-commerce platform entry: Quality inspection report recognized by major e-commerce platforms 3. Used as a sales report: issuing legally effective testing reports to make consumers more confident 4. Papers and research: Provide professional personalized testing needs 5. Judicial services: providing scientific, fair, and accurate testing data 6.
