Internal combustion engines — Piston rings — Part 1: Vocabulary
This part defines the most commonly used terms for piston rings. These terms designate either types of piston rings or certain characteristics and phenomena of piston rings. An annex contains a list of equivalent terms in English, French, Russian, German, Spanish, Portuguese and Italian. Some figures illustrate shapes and reference quantities of concern.
Photography — Determination of ISO safelight conditions
Specifies the method of test for determining the condition for handling sensitized material, which is defined as that condition which provides less than half the maximum safelight exposure which can be given to sensitized material without producing a detectable change in the final image.
Petroleum products — Fuels (class F) — Classification — Part 0: General
Establishes the general classification system which applies to fuels designated by the prefix letter F. Within this class 5 families of products are defined according to the type of fuel. The detailed classification of a family taking into account complementary elements according to the uses, type and properties will define particular products in each category and will be given in subsequent…
Tolerances for building — Presentation of dimensional accuracy data
