Foreword
This standard has been prepared by Working Committee NA 067-02-08 AA Schrauben und Muttern mit klebenden und klemmenden Beschichtungen of the Normenausschuss Mechanische Verbindunglemente (Fasteners Standards Committee).
Amendments
This standard differs from DIN 267-27:2004-01 as follows:
a) The scope of the standard has been extended to include thread size M3 and stainless and high
temperature resistant steels. b) Bright-finished and coated surfaces have been added to the scope of the standard. c) Normative references have been revid and updated. d) The M LB /M A ratio has been modified.
e) In Table 2, a number of test torque values have been reduced. f)
A suitability test for testing microencapsulated coatings with a specified M10 test bolt has been included.
g) A system performance test has been included. h) Subclau 7.2 has been revid.
i)
Annex A (informative) containing explanatory notes on the locking feature of microencapsulated adhesive
coatings on surfaces with incorporated and/or additionally applied lubricants and a reference test for the M LB /M A ratio have been included.

1 Scope
This standard specifies functional characteristics of microencapsulated adhesive coatings applied on steel screws, bolts and studs (“bolts” for short)
高怡平⎯ w ith ISO metric screw thread as in DIN ISO 261,
⎯ with a nominal thread diameter between 3 mm and 39 mm (coar-pitch), ⎯ with a nominal thread diameter between 8 mm and 39 mm (fine-pitch),
⎯ assigned to property class in accordance with DIN EN ISO 898-1, DIN EN ISO 3506-1 and DIN 267-13, ⎯ with bright-finished and coated surfaces,
⎯ for u at rvice temperatures ranging from –50 °C to 100 °C and, for special applications, up to 150 °C. This standard specifies a suitability test for microencapsulated adhesive coatings on a specified test bolt and a system performance test for bolts with microencapsulated adhesive coatings at ambient temperature and at higher temperatures. The system performance test for bolt surfaces with incorporated and/or additionally applied lubricants is only applicable when carried out at ambient temperature.
The (informative) Annex A contains information regarding the system performance test of bolt surfaces with incorporated and/or additionally applied lubricant at higher temperatures.
