ASTM E1209 , Pratique normalisée pour le contrôle par ressuage avec pénétrant fluorescent nettoyable à l’eau(Revision 2018) :

Remplace ASTM E1209  (de février 2010).

Standard practice for fluorescent liquid penetrant testing using the water-washable process

This practice covers procedures for water-washable fluorescent penetrant testing of materials. It is a nondestructive testing method for detecting discontinuities that are open to the surface such as cracks, seams, laps, cold shuts, laminations, isolated porosity, through leaks, or lack of porosity and is applicable to in-process, final, and maintenance examination. It can be effectively used in the examination of nonporous, metallic materials, both ferrous and nonferrous, and of nonmetallic materials such as glazed or fully densified ceramics and certain nonporous plastics and glass. This practice also provides a reference:

• by which a fluorescent penetrant testing method using the water-washable process recommended or required by individual organizations can be reviewed to ascertain its applicability and completeness;

• or use in the preparation of process specifications dealing with the water-washable fluorescent penetrant examination of materials and parts (agreement by the purchaser and the manufacturer regarding specific techniques is strongly recommended);

• for use in the organization of the facilities and personnel concerned with the liquid penetrant testing.

This practice does not indicate or suggest standards for evaluation of the indications obtained. It should be pointed out, however, that indications must be interpreted or classified and then evaluated. For this purpose there must be a separate code or specification or a specific agreement to define the type, size, location, and direction of indications considered acceptable, and those considered unacceptable.

ASTM A388/A388M , Pratique normalisée pour le contrôle par ultrasons des pièces forgées en acier(Revision 2018)

Remplace ASTM A388/A388Ma  (de septembre 2016).

Standard practice for ultrasonic examination of steel forgings

This practice covers the examination procedures for the contact, pulse-echo ultrasonic examination of steel forgings by the straight and angle-beam techniques. The straight beam techniques include utilization of the DGS (Distance Gain-Size) method. This practice is to be used whenever...
