Participation in inter-laboratory comparison programs is an important means of laboratory quality
control and assessing laboratory performance, and these programs can be used by customers or
regulatory bodies for the selection of qualified laborato
ries.
This research describes how to use inter-comparison tests and how to statistically analyse the test
results.
This research has a practical study of assessing laboratories performance in laboratories of the Syrian
textile firms by distributing samples simultaneously to participating laboratories for testing. After
collecting test results, the researcher used scientific methods to handle data to identify the weak points
in laboratories performance and provide them the Feedback and technical advice to Assistance the lab
to defining the measurement problems and evaluating of test methods and instrumentation , and could
introduce some suggestions and recommendations to overcome.
This research deals with the study and analysis the issue of planning and designing statistical sampling plan in specifications and how to use in monitoring and control industrial products quality in the light of the relationship between the producer
and the consumer by examining certain quantities of production based on criteria pre defined in order to judgement on the batch viability to reach an acceptable quality level or not.
The acceptance preview concept involves on examination of materials and parts of the external source, product examination in its different parts and final examination for the product by one customer or more, by using American system (MIL-STD-105E) and tables of (Dodge and Roming) which related with statistical sampling plans.
This research shows theoretical and practical how to design statistical sampling plans to adjust the industrial products quality and its application in products quality control of Jood company for assembling electrical tools using statistical program (SPSS).
The study concludes to results confirm that the company doesn't have an application of statistical techniques in quality control and limited to measuring the output quality characteristics in the laboratory without a clear scientific method in examine batches such as designing statistical sampling plan.
Jood company has certificates of Syrian and European standards of quality control so it had to be a recommendation for the company in application the scientific statistical sampling techniques in all production stages and training the staff on its application using specialists in the field of quality with plans showing the place and the time of doing sampling and determine sampling points in different production stages in order to promote the company with its products and provide products almost free of defects which qualifies the company to competition in foreign markets, not local.
Our study shows that only 31 % of the world issue the chemical periodicals
/1058/. Out of the 1058, 92 % are issued by the third of these countries (20
countries which is equal to 10 % of the world), in which the number of refereed
periodicals is
higher than the unrefereed ones. The ratio was the same when the
periodicals were categorized by the spoken language.
The microbiological limits are considered to be one of the quality
criteria that affect pharmaceutical. Herbal drug medicine is of some
specialty since their raw material contains a high bioburden.
According to pharmacopoeia, Herbal drugs are main
ly whole,
fragmented or cut, plants, parts of plants, algae, fungi, lichen in an
unprocessed state, usually in dried form but sometimes fresh.
