This standard practice provides a standardized method of measuring hull roughness to enable reproducible and comparable readings from similar gauges regardless of geographical location.
One of the factors affecting a ship's performance and fuel consumption is the roughness of its foul-free underwater hull. the Condition and type of paint system used may have a major influence on hull roughness and ship performance. Hull roughness has a major impact on vessel fuel efficiency and exhaust emissions. This standard focuses on the mechanical roughness of the hull.

HISTORICAL DOCUMENT. Test for the presence of surface soluble salts before application of a coating system. Previously coated or eplacement substrates only. Does not include allowable limits of soluble salts.
HISTORICAL DOCUMENT. Corrosion prevention and control (CPC): • Attributes of product, system or facility. • Material selection and design. • Relevant topics. • Design, fabrication, construction, operations, maintenance & sustainability.
HISTORICAL DOCUMENT. This NACE standard test method describes a reliable measuring methodology for determining the gouge resistance of coating systems used on buried ferrous metal pipelines.
HISTORICAL DOCUMENT. The purpose of this NACE International test method is to standardize the testing methods and conditions used to determine acceptable temperature limits for personnel protection for insulative coatings in accordance with ASTM C1055. The temperature limits determined when using this test method are specific for each coating tested at a particular thickness and substrate temperature. A standardized test method can validate the temperature limits of a coating used for personnel protection, and enable direct comparison of its performance. This test method is intended for use by facility owners, engineers, health and safety specialists, coatings manufacturers, and other interested parties.
HISTORICAL DOCUMENT. Defines the Very Thorough Cleaning (WJ-1) degree of surface cleanliness - one of four levels (WJ- 1,2,3,4) achieved by the use of waterjet cleaning.
Defines the Clean to Bare Substrate (WJ-1) degree of surface cleanliness of coated or uncoated metallic substrates achieved by the use of waterjet cleaning. Other degrees listed in overview below.
HISTORICAL DOCUMENT. Defines the Very Thorough Cleaning (WJ-2) degree of surface cleanliness - one of four levels (WJ- 1,2,3,4) achieved by the use of waterjet cleaning.
HISTORICAL DOCUMENT. Defines the Thorough Cleaning (WJ-3) degree of surface cleanliness - one of four levels (WJ- 1,2,3,4) achieved by the use of waterjet cleaning.
Defines Thorough Cleaning (WJ-3) degree of surface cleanliness of metallic substrates by use of waterjet cleaning. One of four (Clean to Bare Substrate, Very Thorough, Thorough, Light).
Defines the Light Cleaning (WJ-4) degree of surface cleanliness of metallic substrates by the use of waterjet cleaning. One of four (Clean to Bare Substrate, Very Thorough, Thorough, Light).
