1
Are you trying to understand the special inspection levels on the AQL chart?
2
Now, this is a topic that people sometimes get confused by
3
because they're looking at the general levels and the special levels and they're kind of unsure about how they work.
4
So that's what we're going to be covering today is what are the special levels in contrast the general levels
5
and how do you use them during an AQL sampling inspection.
6
So let's get into it.
7
Okay so here we are looking at table one of the AQL chart
8
and we can see the special inspection levels right there next to the general levels.
9
Now if you know how to determine your sample size then what you've already figured out is
10
that if you use a general level it's going to give you larger sample size
11
and if you use a special level that is going to give you a much smaller sample size.
12
So for example, you've got 2,000 units in your order,
13
and you use general two,
14
well, that's 125 units in your sample.
15
And if you use S1,
16
well, that's only five units in your sample.
17
So what gives here?
18
Why would you ever use such a small sample?
19
The key thing to understand here
20
is that you're not choosing between using the general level or the special level for your inspection.
21
It's that you're using them both together during your inspection.
22
So the general level that you use applies to the inspection as a whole.
23
Meanwhile, there can be special levels that you use for specific tests on your inspection checklist.
24
And those are going to be tests that warrant a smaller sample size.
25
So what kind of tests are going to warrant a smaller sample size?
26
Well, it's going to be those that are either destructive to the item that you're checking,
27
they're expensive or time-consuming to conduct,
28
or that tend to yield similar results across all the items in the lot.
29
And so it doesn't necessarily make sense to check so many of them.
30
So here are some examples.
31
The first one is a drop test where you're dropping a carton
32
or an item from a specific height multiple times to see if the packaging or product breaks.
33
Another example would be a sleep mode test for an electronic product where you verify
34
that it turns off automatically after 30 minutes of inactivity.
35
And that's obviously going to be very time consuming if you do that on all of the items.
36
example is a carton dimension check because you're checking the carton height width
37
and depth and that's going to be relatively similar across every carton
38
that you check so on the AQL chart there are four special inspection levels S1,
39
S2, S3, and S4.
40
Of course S1 is going to give you the smallest sample size
41
while S4 is going to give you the largest sample size.
42
And And, you know, at Insight Quality,
43
we tend to use S1 for tests that are more destructive.
44
And for things like function tests,
45
we might often use S4.
46
But when you're deciding which ones to use,
47
it really comes down to the specifics of your product and your situation.
48
So I hope this was informative for you.
49

  • General levels: Broader categories generating larger sample sizes for more comprehensive inspections.
  • Sample size: The number of items selected for testing during an inspection.
  • Destructive tests: Tests that can damage items, requiring smaller sample sizes due to cost or time constraints.

Step-by-step Shadowing Guide

To effectively utilize the shadowing technique for this video, follow the steps below, which can significantly help improve English pronunciation and enhance comprehension of technical terms:

  1. First listen: Watch the video completely once to grasp the overall message and context.
  2. Break it down: Divide the transcript into manageable sections that correlate with the video's flow. Each section should focus on one key concept, such as general versus special levels.
  3. Repeat aloud: Use the shadowing technique by repeating phrases immediately after the speaker. Focus on mimicking intonation, stress, and rhythm. This practice can be particularly effective for mastering the unique vocabulary used, such as "AQL chart" or "special levels."
  4. Record yourself: After shadowing, record your voice and compare it to the original. This will help identify areas requiring improvement, especially in pronunciation.
  5. Engage and interact: Join forums or conversation groups that focus on AQL and quality inspection terms. Discussing these concepts in English will bolster your confidence, especially in settings like IELTS speaking practice.

Utilizing a shadowing site dedicated to improving English pronunciation can help you further refine your skills. Regular practice not only enhances your understanding of industry-specific terminology but also transforms your spoken English, making you more articulate in both social and professional contexts.

Qu'est-ce que la technique du Shadowing ?

Le Shadowing est une technique d'apprentissage des langues fondée sur la science, développée à l'origine pour la formation des interprètes professionnels. Le principe est simple mais puissant : vous écoutez de l'anglais natif et le répétez immédiatement à voix haute — comme une ombre suivant le locuteur avec un décalage de 1 à 2 secondes. Les recherches montrent une amélioration significative de la précision de la prononciation, de l'intonation, du rythme, des liaisons, de la compréhension orale et de la fluidité.
