Acceptance quality level

With attribute data the product either has or has not the ascribed attribute - it can therefore either pass or fail the test. There are no gray areas. Attributes are measured on a go or no-go basis. With variables, the product can be evaluated on a scale of measurement. However, with inspection by attributes we sometimes use an acceptable quality level (AQL) that allows us to ship a certain percent defective in a large batch of product -...

When using the defect-detection approach to quality control certain problems develop. Inspection does nothing to improve the process and is not very good at sorting good-from-bad. Also, sampling plans developed to support an acceptable quality level (AQL) of 5%, for example, say that a company is content to deliver or reject 5% defects. 

Acceptance criteria means the product specifications and acceptance/rejection criteria, such as acceptable quality level and unacceptable quality level, with an associated sampling plan, that are necessary for making a decision to accept or reject a lot or batch (or any other convenient subgroups of manufactured units). 

As with other packaging components, the incoming tests and specifications of metered valves, inspection attributes, and AQLs (acceptable quality levels) will need to be coordinated with the supplier. The valve should be considered as a critical package component and have incoming performance tests, such as spray weights and weight loss [13,14], The performance test could be conducted on a sample of the valve lots from either scale-up or pilot trials before the validation lots are prepared. This information may also be available for each lot from the supplier. It is recommended that each test shown in Table 3 be conducted on at least three valve lots as part of the validation program. 

Procedures should be established and recorded to ensure that an acceptable quality level is associated with input data extraction and use, model execution and validation procedures. The procedures described by the EPA s Good Automated Laboratory Practices (GALP) should be considered, where applicable.

Acceptable quality level is related to the quality required in the product. The acceptable quality level is the maximum percentage nonconformity that, for the purpose of the sampling inspection, can be considered satisfactory as a process average. ... 

The acceptable quality level has a particular significance in the design and use of acceptance sampling plans, e.g. ISO 2859 - 1. 

Therefore, an acceptable quality level of 0.010 would mean that one nonconformity in 10 000 is the limit of acceptance. 

Two sets of standards are set for empty capsules, analytical and functional. Capsules, like all other pharmaceutical preparations, must comply with cGMP norms and must be made of materials that comply with pharmacopeial chemical and microbiological standards. However, these tests do not indicate whether a capsule will run well on a filling machine. Series of functional tests are applied by the manufacturers. The critical dimensions of a capsule (the lengths and diameters of the caps and bodies) are checked. It is a continuous production process, and there will be a very small proportion of visually defective capsules. Standard statistical sampling methods are used to estimate quality from samples. The manufacturers and users agree on acceptable quality levels (AQL). The faults are... 

Acceptable quality level (AQL) inspection acceptance criteria are applied to the inspections. Visible foreign particulate matter is considered a critical defect. Thus, AQL levels (the greatest percentage of defective units still acceptable for release) are 0.25-1.0% of the lot size. Consult the American National Standards Institute/American Society for Quality Z1.4 guideline for more detailed information on AQL sampling. The drawbacks of manual inspection are that it is prone to human error and is subjective.

Inspection procedures, and acceptable quality levels (AQLs) related to critical, major and minor defects may be part of the specification document but are more likely to be in a general information support manual, unless these are specific to the item concerned. 

Pesticide presence in groundwater is of particular concern. On average, 65% of European drinking water is supplied from aquifers and they often take a long time to recover an acceptable quality levels. According to the report Groundwater quality and quantity in Europe out of approximately 600 pesticides usually applied, only about 30 have been monitored. ... 

Glove quality standards have been established by the FDA based on a sampling scheme and a quality assurance test known as the 1000 mL water leak test described in the Code of Federal Regulations, 21 CFR 800.20 [127]. The Final Rule was published in December 12, 1990, and became effective March 12, 1991. The acceptable quality level is a maximum failure rate of 2.5% for surgeons gloves and of 4.0% for patient examination gloves as determined in this water leak test. 

ISO 2859-1. 1989. Specification for sampling plans indexed b acceptable quality level (AQL) for lot-by-lot inspection. 

Let s look at right quality the level the customer wants or better if possible. Most customers want zero defects. The traditional method was to use a random sample and develop an acceptable quality level (AQL). A sampling plan was developed and then the sampling standard tables were looked at to determine if the lot should be accepted or rejected. Using the acceptable quality level indicated that the customer was willing to accept some defects. In most cases today this method is not used. With the advent of Six Sigma the levels of acceptability have come way down, approaching zero defects. 

A typical problem in the steel industry concerns the allocation of orders to leftover surplus stock ([71]). The problem of matching unique customer requirements to existing inventory is termed the surplus inventory matching problem. The surplus stock arises because orders maybe canceled after units are produced, because produced units are below acceptable quality levels, or because surplus units had been intentionally created to reduce customer lead times. While this problem is described from the context of steel mills and paper mills, the problem can be framed in a more general form, e.g., as dealing with leftover trucking capacity or production capacity.
