Table C.3 – Testing criteria applicable to small-quantity imports
In the event that the sample test results of the representative shipment samples do not comply with the applied standard, a second sampling is permitted with a sample quantity double that of the first sampling. The shipment shall only be assessed as conforming to the technical requirements of the regulation when the sample test results on all samples taken in the second sampling comply with the applied standard.
C.3. Certification records
The certification body must establish certification records to demonstrate that the product certification process has been carried out in accordance with the guidance of Circular No. 28/2012/TT-BKHCN and TCVN ISO/IEC TR 17026:2016.
The certification body must store the technical documentation of the certified product, including the following contents:
– Technical documents including a description of the product’s technical characteristics; circuit diagrams; a list of main components and parts; user manual; product installation instructions;
– Color photographs of the exterior, interior, and the product label. The photographs must show the shape, structure, component distribution, and details of components and parts critical to product safety. The certification body may coordinate with the testing organization to obtain product photographs from the testing organization without having to re-photograph the product.
– A list of main components clearly showing the component name, model/type designation, technical specifications, certification marks printed on the component, and the conformity certificate number issued for such component (if any);
– A detailed description table of the differences between product types within a product family and an analysis of why the sample selected for type testing represents the product family, if the assessment is conducted on a product family;
– Type test results of the product or product family;
– For certification assessment according to Method 7, the technical documentation must additionally include the test results on representative shipment samples and the results of the assessment of conformity between the samples taken from the shipment and the type-tested samples.
– For certification assessment according to Method 5, the technical documentation must additionally include test results from surveillance and re-certification;
If existing test results are recognized and used prior to the certification assessment, the technical documentation must include the results of the assessment of conformity between the certified product sample and the technical characteristic descriptions, images, structure, and the list of main components shown in the recognized and used type test results.
C.4. Post-certification surveillance
During the validity period of the certificate according to Method 5, the certification body must conduct periodic surveillance assessments at a frequency of no more than once every 12 months, or unscheduled surveillance assessments when there are complaints or when quality issues are detected in goods on the market.
During the validity period of the certificate according to Method 1, when there are complaints or when quality issues are detected in goods on the market, the certification body must conduct an unscheduled surveillance assessment by taking samples at the warehouse of the manufacturing or trading organization/individual or by taking samples from the market and re-testing these samples to reach a conclusion regarding the quality of the certified product.
C.5. Suspension, cancellation of validity, and withdrawal of Certificates
In cases where there is evidence of product non-conformity through periodic or unscheduled surveillance assessments, or if the organization/individual requesting regulation conformity certification fails to fully perform the obligations specified in Clause 2, Article 49 of the Law on Standards and Technical Regulations, the certification body shall, depending on the severity of the violation, implement appropriate handling measures such as suspending the certificate for a period not exceeding 3 months or canceling the validity and withdrawing the Certificate.
Upon suspension, the violating organization/individual must stop releasing the suspended products to the market, implement appropriate measures for non-conforming products already in circulation, and rectify the violations. If the suspension period expires and the violating organization/individual has not completed the rectification of the violations, the certification body shall consider implementing the measure of canceling the validity and withdrawing the Certificate.
When the validity is canceled and the Certificate is withdrawn, the violating organization/individual must stop releasing the products whose Certificate has been withdrawn to the market and must implement appropriate measures for all non-conforming products already in circulation.
C.6. Handling of shipments not conforming to technical regulations
In the event that testing and assessment results show that the product or imported shipment does not conform to the technical regulation and the organization/individual requesting certification cannot rectify these non-conformities, the certification body shall issue a notice of non-conformity to the requesting organization/individual, and simultaneously to the relevant state management agencies for coordinated surveillance and handling, and report to the Commission for the Standards, Metrology and Quality of Vietnam as regulated.
In cases where test results according to the standard versions listed in the List of Electrical Equipment are non-conforming but are conforming when tested according to newer standard versions, the test results according to the newer standard versions shall be accepted as the basis for regulation conformity certification.
ANNEX D
GUIDANCE ON PRODUCT FAMILIES AND SELECTION OF REPRESENTATIVE SAMPLES FOR PRODUCT FAMILIES
D.1. Reference documents
This guidance is developed based on the IECEE OD-2041 Ed 2.0 – Guide on Product Families, Family Ranges or Series of Products.
D.2. Definition of product families
To reduce testing costs and time, product types with the same characteristics are grouped into the same product family, and type testing is only conducted on one or a few product types to represent the entire product family.
The definition of a product family is as follows:
All product types within the same product family share the same design, structure, components, or essential parts to ensure compliance with the requirements of the standard.
The factors that may affect product safety are the same across all product types within the same family.
Depending on the product category, product types in the same family may have certain differences such as size, color, external shape, and may also differ in electrical parameters such as rated current, operating current, etc.; however, the nature of these differences does not alter the impact on safety of one product type compared to others in the same family.
If the standard applied to the product already provides guidance for determining the product family, the product family shall be determined according to that applied standard’s guidance.
For electrical installation equipment, manufacturers usually categorize product types by product family. The following suggestions are referenced to determine a product family.
D.2.1. Electrical switches
– Shared rated current, contact structure, contact base, and actuating member.
D.2.2. Plugs and socket-outlets
– Shared rated current, structure of electrical contact parts, and base of electrical contact parts.
D.2.3. Socket-outlet adaptors, cord extension sets
– Refer to D.2.2;
– Shared type and cross-sectional area of the connection cord.
D.2.4. MCB, RCBO, RCCB
– MCB according to Annex C – TCVN 6434-1:2018
– RCBO according to Annex A – TCVN 6951-1:2007
– RCCB according to Annex A – TCVN 6950-1:2007
D.3. Selection of representative samples for product families
The product type or group of product types selected to represent a product family must be those with the highest probability of non-conformity with the requirements of the standard.
Some examples of representative sample selection:
|
ORD |
Product |
Choose the representative for the product families |
|
5 |
Socket-outlets, plugs, socket-outlet adaptors, cord extension sets | Types with the maximum configuration. Priority is given to common types with higher production volumes than others |
|
6 |
MCB, RCBO, RCCB | According to the guidance of the applied standard |
