United Kingdom BS 1806 Specifi es dimensions (inches) for inner diameters and cross-sections and their tolerances including grooves. O-ring dimensions are identical with the Parker 2-xxx series. Table 11.1 gives a cross-reference among the various European standard specifi cations. BS 4518 Specifi es dimensions and tolerances together with groove dimensions. Cross-section diameters are: 1.6 / 2.4 / 3.0 / 5.7 and 8.4 mm France The following French standards base upon ISO 3601 Parts 1 to 3: NF-T-47-501 is comparable with ISO 3601 Part 1. NF-T-47-502 is comparable with ISO 3601 Part 2. NF-T-47-503 is comparable with ISO 3601 Part 3. French purchase codes R 1 to R 27 are identical with Parker sizes 5-578 to 5-606. R 28 to R 88 are identical with Parker sizes 2-325 to 2-349 and 2-425 to 2-460. For more details, cf European O-ring codes, Table 11.1. Italy A committee for seal and hose standardization exists in the UNI which recommends the use of the American AS 568 A standard specifi cation. In certain areas the French R 1 to R 88 are used. Sweden O-rings are standardized under SMS 1586, Swedish military standard. Cross sections 1.6 / 2.4 / 3.0 / 5.7 and 8.4 mm are recommended. United States AS 568 B (Aerospace Standard) Published by the SAE (Society of Automotive Engineers) specifi es sizes and tolerances. The cross-section tolerances correspond to ISO 3601/1 and DIN 3771 Part 1 (within a few hundredths of a millimeter), see Table 11.1, Cross Reference List. 8.3 Ordering Addresses DIN and DIN ISO standard specifi cations and VDMA recommendations can be obtained from: Beuth Verlag GmbH Burggrafenstrasse 4-10, D-10787 Berlin AMS and SAE specifi cations can be obtained from: SAE 400 Commonwealth Dr. Warrendale, PA 15096-0001 ASTM standard specifi cations can be obtained from: ASTM 100 Barr Harbor Drive.
