Padrões de Inspeção de Qualidade

 

Como os inspetores da AQF executam inspeções de qualidade ? 

Asia Quality Focus executa seus serviços de inspeções de produtos de acordo com:

  • Padrão internacional de qualidade reconhecido: ISO 2859-1 (ANSI/ASQC Z1.4-2003), também conhecido como Tabela AQL

  • Requisitos do cliente, especificações, critérios e instruções.

  • Nossa experiência e expertise em controle de qualidade.

  • O bom senso ocidental.

 

O que nós inspecionamos durante uma inspeção de qualidade ?

  • A quantidade produzida (semi acabada, acabada e embalada)

  • O aspecto visual (checagem plástica da produção em massa)

  • As especificações do produto (tamanho, dimensões ,cores)

  • A rotulagem e identificação

  • O embalamento e empacotamento

  • Todas as funções possíveis e possíveis testes 

 

Quais padrões de qualidade que utilizamos ?

We randomly select a sampling size quantity (based on the AQL tables) to be inspected. We inspect the sampling size and classify the defects into critical, major and minor defects.

According to the number of defects found for each type and according to the number of defects allowed (figures given by the AQL tables), we will advise you to accept or to reject your shipment.

Then it is up to you to make your own decision based on the information and recommendations we have provided to you.

We suggest that you discuss the findings with your vendor and the manufacturer and you ask him to pay attention/rework/re-produce/sort out the products.

 

Como utilizar a Tabela AQL ?

The AQL tables will help to determine the sampling size we will need to inspect according to your ordered quantity and your level of severity (I, II or III). The standard level, the one used by default and by 98% of the people is the level II for a standard inspection.

If your order has multiple references, ideally we should at least inspect a level II on each reference. 

Indeed, for a standard order,  the standard level II from the AQL  gives the minimum sampling size we should check per reference if we do not want totake additional risks. If we inspect a general level II sampling size on a multiple references orders, then the sampling size is diluted and divided by the number of references, increasing the risks as the sampling size must be representative enough.

Please check here if you want to see more explanation about the AQL tables and the AQL tables itself.

Asia Quality Focus uses the Acceptance Quality Limit standard during product inspections, unless an other standard is requested by the client. The standard definition of Acceptance Quality Limit (AQL) is "the maximum defective percent (or the maximum number of defects per hundred units) that, for purpose of sampling inspection, can be considered satisfactory as a process average".

In order to find the necessary sampling size to be inspected, we look at the first chart and find on the left side the range of items being produced in total. You have the choice of levels I, II and III, with Level III being the most stringent testing and level I being the least. Level II is the standard and is most often used. For example, if you are producing 8000 items, at level II you have the letter L, which in the second table says to inspect 200 items.

On the top of the second chart are the defect levels, ranging from 0 to 6.5. You can choose which level to apply for your type of defect: critical, major and minor. Usually most importers will choose standard defect levels which are 0/2.5/4 but one can choose 1/1/1 if he wishes or 0/1.5/2.5 like in the automotive industry. Using the standard 0/2.5/4 defect levels and a sample size of 200, we see that if you have more than 0 critical defects, 10 major defects or 14 minor defects, you should reject your shipment. Of course the decision about what to do after your received the inspection results belongs to you. Most importers will wish to discuss all inspection findings with their vendor/manufacturer in order to improve whatever possible. In case the inspection results are very close to AQL limits, it is important that you double check if the level of found defects is acceptable to you or not.
