Hello I need some help to solve a difference of opinion. A number of standards require isopropyl alcohol for durability of marking test. e.g. IEC 1010-1, Clause 5.3 and IEC 601-1, Clause 6.1.z.
The difference in opinion is in the concentration. The standards just state "isopropyl alcohol". Some say 70% others say 100%. What are other people using? Ned Devine Entela, Inc. Toll Free: 1 800 888 3787 Ext. 671 Direct: 1 616 248 9671 Fax: 1 616 248 0591 e-mail: [email protected]
