Standard Calibration Sets for Manual Inspection Booths
Referee Level Particle Standards (RLPS™)
Since the Referee Level Particle Standards are used for training and inspection qualifications the set must meet the strictest requirements for clarity and particle size determination. The containers provided by the customer are requested to be cleaned and depyrogenated as if they were to be used in production. We rewash the containers and stoppers in the preparation process. The containers are examined very carefully to insure that they free of any contamination prior to the seeding operation. We have found that container quality has a considerable influence on the preparation time. An important part of the preparation is to insure that all of the trace elements have been removed from the container interior walls. Each container is sealed with a closure that is laser matched with unique Lot/Serial number that identifies the actual content of the container. The customer is supplied with Certificate of Analysis (COA) that describes the container, its contents and the seed particle material and seed particle size (see sample sheet below). Each RLPS™ set is seeded with particles that are populated from very small (40-50 µm) to very large (800 - 1100 µm). The largest percentage of particles is concentrated is near the visible limit of human inspectors at 500 foot-candles of illumination for container of a particular size. Small containers (1 ml) shift the center of the particle distribution toward small particle sizes (Level I) and larger containers (500 - 1000 ml) shift the center of the particle distribution to large particle sizes (Level VI). The container material also has an influence on which Level particle standards should be used for seeding. Each individual seed sample is examined for shape and measured precisely to ±1 µm, it is then photographed for inclusion into your records prior to seeding. You are supplied with all documentation and photographs on a CD-ROM included with samples. Note: The RLPS sets only include stainless steel and borosilicate glass spherical particles. Spherical particles are required so that particle orientation will not influence the perceived size of particle when determining the efficiency of each operator in the human baseline determination study. Referee Level Particle Standard - Basic Set Includes:65 vials total (16 seeded, 49 clean) Stainless Steel Spheres sizes range from 50µm - 1000µm Glass Spheres (transparent) sizes range from 70µm - 500µm Referee Level Particle Standard - Extended Set Includes:100 vials total (36 seeded, 64 clean) Sample RLPS data sheet is shown below. Each sample is marked with a unique identification number.
Note: Standard Set particle sizes area subject to changes. Referee Level Particle Standards - Extended Set 2 Includes:100 vials total (36 seeded, 64 clean) of the Standard
Set plus Additional Samples requested by All sets are provided with photographs of the actual seeds used in the samples. The report includes the actual seed sizes as measured with an NIST traceable translation stage and high power microscope. All containers are laser marked on the aluminum closure (vials) with a indelible 2-D code and equivalent human readable code.
