Test Specimens and Conditions 6. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. It is the responsibility of xstm user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Pencil hardness measurements have been used by the coatings industry aetm many years to determine the hardness of clear and pigmented organic coating films.
ISO Determination of? 005 nanocomposite hard coatings Ramachandra S. This is related to the low thickness and the high deposition temperature of these coatings as compared with other TiN layers. The moment new editions of the standards you monitor are d3336, changes are made, or appendixes are published, you will be alerted by email. Record each end point if applicable for gouge and scratch hardness see 8. NOTE 2—In conducting the test, if the sharp edge of the lead is slightly chipped or crumbled, the lead must be resharpened.
One of the most ubiquitous and challenging applications for glass today is that of the touch screen on portable devices. The pencil is held?
The benefits of a subscription: Even though surface-modified nanoparticles ast utilized in nanocomposite hard coatings, coatings often result in poor scratch resistance if nanoparticles are not homogenously distributed in the hybrid matrix. Read more about subscriptions. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
ASTM D3363 – 05 PDF
This test method has also been used to determine the cure of these coatings, especially when forced dried using heat. Other advances include antimicrobial and anti-smudge screens.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
A number in parentheses indicates the year of last reapproval.
Currently, front windshields are made of laminated glass with a thin layer of epoxy between two layers of glass that serves to hold the shards together when broken. Texture is connected with characteristics, processing degrees, construction methods, and the types and elevation styles of buildings. All the buildings are ornamented by colors. Last previous edition approved in as D — D336 Standard supply includes: Webolda PDF this is a blog of hungarian student.
Castor oil is modified chemically by graft copolymerisation with methyl and butyl methacrylates. Pencil scratch testing device. This test method is especially useful in developmental work and in production control testing in a single laboratory. If this test method is used as a basis for purchase agreement, maximum precision will be achieved if a given set of x3363 pencils be agreed upon between the purchaser and the seller.
It should be recognized that the asmt obtained may vary between different laboratories when different pencils as well as panels are used. 0 oil-based polyesters N. Every effort should be made to standardize the hardness of the lead used and the technique followed. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
TiN coatings astm d 05 had good adhesion to the substrate.
