This document specifies polymers commonly used in manufacturing dental instruments.
It is applicable to polymers used to manufacture either an entire instrument or part of an instrument.
It is applicable to single-use and reusable dental instruments, whether they are connected to a power-driven system or not.
This document does not apply to oral appliances and devices (e.g. splints, mouthpieces, crowns, bridges, implants), to instruments used long-term in the mouth of the patient or to devices and instruments not made of polymers.

This document specifies an atmospheric accelerated test procedure in two closely related variants that contain intermittent salt exposure combined with dynamic humidity patterns: variant A at constant dew point and variant B at constant temperature. These variants are used in assessing the corrosion resistance of metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from, for example, winter road de-icing salt. The results obtained do not permit far-reaching conclusions on the corrosion resistance of the tested metallic material under the whole range of environmental conditions in which it can be used. Nevertheless, the method provides information on the relative corrosion resistance of a material exposed to a salt-contaminated environment with varying humidity conditions.
The two accelerated laboratory corrosion test variants are applicable to:
—     metals and their alloys (ferrous and non-ferrous);
—     metallic coatings;
—     chemical conversion coatings;
—     organic coating on metals;
—     a combination of materials and coatings that include galvanic interactions and/or crevice conditions.
NOTE 1        If testing low-alloy stainless steels according to this document, especially austenitic grades, there is a risk of exaggerated pitting, which is not representative of most service environments.
NOTE 2        This document is not suitable for testing of wax and oil-based rust protection agents, due to the constantly elevated temperature condition of the test.
This document also specifies requirements on the test equipment and contains detailed procedures for quality control, including recommended instrumentation.
This document does not specify the dimensions of the tests specimens, the exposure period to be used for a particular product, or the interpretation of the results. Such details are provided in the appropriate product specifications.

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts with slot(s), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
NOTE            These nuts are designed with mmin as specified ISO 4032 and with an overall height h greater than in ISO 7042, in order to accommodate the prevailing torque feature with slot(s); this height h contributes to the nut resistance due to the number of engaged threads. hmin values have been calculated as a function of hmax together with a ratio hmax/D that progresses regularly with increasing diameter; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system).
If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.
NOTE            These nuts are designed with an overall heigth hmin = mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. hmax has been established in function of hmin; therefore, the tolerance (hmax – hmin) does not follow the ISO code system for tolerances (IT system).
