Halle's Roughness Standard is 4058. When we placed orders in May 2007, Halle's Roughness Standard is Series 4058. The type numbers are as follows from now on.Ra with about 0.2µm is Type No.4058/01A1/Pk, Ra with about 0.5µm is Type No.4058/01A2/Pk and Ra with about 1.5µm is Type No.4058/01A3/Pk. The catalog in Japanese has 4 pages, please click here. The catalogue of Halle's Standards in Japanese only Last Updated : August 2006 Halle's Standard Series 2058 will be replaced by Series 4058. Halle's Roughness Standard Series 2058 will be displaced by Series 4058 step byh step. According to the manufacturing technique for the Super fine surface finish standard the grinding surface is improved and Firm Halle has potential to develop a new standard. The measuring space is 17mm in length and 5mm in width having the irregular grinding profile, which is repeated with aperiodic length from 2mm to 4mm.The left drawing shows old 2058 and the right one shows new 4058 Roughness Standard 4058...only in Japanese
Last Updated : October 2005 Sales of the Calibrating Standard 2080 for a Stylus and/or an Optical Roughness Measuring Instrument The tendency toward the roughness measurements by Optical surface measuring instruments such as confocal and interference microscopes is increasing. Because the optical system is getting faster than the stylus measuring system. Moreover almost such microscopes can calculate the roughness parameters according to the ISO and/or JIS Standards. However it is not clear that the results are the same as the Standards. The Standards were made to meet the requirements of the Contact type roughness measuring instruments using the stylus, not to meet the optical microscopes. The comparison between the stylus and optical system got many results but it is not easy to satisfy with those results. There is a reason that the horizontal resolution of the optical systems is not enough sensitive and the tracing length of the Standards is not obtained.This newly announced Standard 2080 has grooves on the surface and calibrates the depth. Special features are: 1) The measuring routine of optical microscopes software is on the assumption of the flat measuring surface, so the measuring surface of 11mm diameter and the base surface of 40 x 20mm are adjusted pararell to both surfaces each other. 2) The groove has an oblique groove flank, which gives the clear results under the measurements by optical microscopes. 3) The high reflectivity gives a better S/N ratio to optical microscopes. 4) There are the following 6 grooves. 0.24, 0.75, 2.4, 7.5, 24, 75 µm The detail is the following PDF-file.

Last Updated : November 2004 April 2003 Sales of Halle's Standard 2070 for Super Fine Surface Finish, Germany
They are the measurement standards for Surface texture Profile Method according to JIS B0659-1:2000 (ISO 05436-1:2000). The traceability during production process is required under the ISO 9000 series. The traceability cannot obtain without a standard. Firm Halle in Germany have manufactured some standards that are calibrated the PTB (The Physical and technical federal laboratory in German) long time ago. In 2001 and 2002 all Japanese standards related with surface texture profile method (contact stylus instruments) were revised and JIS B0659-1 (ISO 5436-1) "Measurement Standards - Part 1 : Material Measures" was newly established in Japan. Several standards are decided as the measurement standards and Firm Halle manufactures depth measurement standards and roughness measurement standards. Relations for Surface roughness contact instruments among all standards in JIS and ISO Catalogue(only in Japanese) We have made other 5 technical materials taking the opportunity of this revision of JISs till 2002, please ask us these materials by E-mail, if necessary.  Please use E-mail to ask us technical materials (only in Japanese) ! Last Updated : February 2003 What are the Halle's Calibration Standards ? Calibration Standards for Stylus instruments
Firm Halle-Präzisions-Kalibriernormale GmbH, Germany manufactures measurement standards for contact stylus roughness testers and can deliver it with PTB Certificate. The traceability is required in production line for ISO 9000 series. The Halle's standards are used for calibration of roughness testers in production lines too. In Japan recently many Japanese Industrial Standards (JIS) for roughness measurement are revised according to the standardization of ISO. The Halle's standards are conformed to JIS B0659-1:2002 (ISO 5436-1:2000) "GPS-Surface Texture: Profile Method; Measurement standards-Part 1". Firm Halle manufactures Type A2, Type D1 and Type D2 in conformity to JIS (ISO). Depth Standard 2060 and Roughness Standard 2058 |
