Voltage increments for the step-by-step test shall be determined from short-time test results as follows: Relative viscosities of Groups 03 and 04 shall be measured on 0. Relative viscosity of Group 08 shall be measured on 9. D — 00a: These will be spelled out in detail and identi?
All other grades are listed by requirements. In general, the suffix letter gives the general requirements needed and the? Nylon Processing and T Table PA is used to specify the group of nylon and Table A or B is used to specify property requirements. These asttm be agreed upon between the user and the supplier, by using the suffixes as given in Section 5. Details of these methods will be included in a future revision of Speci?
Packing, Packaging, and Marking R Tensile strength and elongation shall be determined on Test Method D test specimens 3. If necessary, additional control of these reinforcements and additives can be accomplished by use of the suffix part of the system see Section 5. D066 designation PAG35 indicates the following: All tests shall be conducted on as-molded not annealed specimens conditioned dry-as-molded.
D40066 example can be applied to replace all table values, that is, tensile stress, notched Izod asgm, and heat de? L Izod impact requirements for Group 04 materials based on specimens with a Flexural modulus shall be determined on Test Methods D test specimens 6. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the asfm of regulatory limitations prior to use.
It is possible that materials incorporating other pigments or soluble stabilizers, or both may prove adequate for particular applications. Start the test within 2 min after removing the specimen and wiping with a dry cloth. After the humidity conditioning speci? These are electrical limits applied to reinforced nylons when control of their electrical properties is required. NOTE 21—Physical properties of most nylon resins are highly dependent upon the moisture content of the molded item.
NOTE 8—Ash content of? The dissipation factor is the cotangent of the dielectric phase angle or the tangent of the dielectric loss angle.
Referenced Documents purchase separately The documents s4066 below are referenced within the subject standard but are not provided as part of the standard. The main property affected is ductility, as illustrated by a reduction in Izod impact and elongation values.

D — There may be other requirements necessary to identify particular characteristics important to specialized applications. This standard has been approved for use by agencies of the Department of Defense. Viscosities for D40666 03, 04, 06, and 08 are measured as described as follows.
Link to Active This link will always route to the current Active version of the standard. The specimens tested are 3.

NOTE 4—An example of this classi? Five specimens shall be tested. O Group 07 nylons are presently used commercially only as reinforced materials. F Flexural modulus shall be determined on Test Method D test specimens 3. This section may also include descriptions of the changes or reasons for the changes, or both. The specimen shall be of sufficient size so that two 4.
General Principles ISO Inherent viscosity of Group 06 shall be measured on 0. It is possible, by agreement between the buyer and the seller, that materials incorporating other pigments or soluble stabilizers, or both, may prove adequate for particular applications. It is the responsibility wstm the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
