35% fluorine by weight);
5. Glass (including vitrified or enamelled coatings or glass lining);
6. Graphite or 'carbon graphite';
7. Nickel or alloys with more than 40% nickel by weight;
8. Tantalum or tantalum alloys;
9. Titanium or titanium alloys;
10. Zirconium or zirconium alloys; or
11. Niobium (columbium) or niobium alloys;
Technical Note:
For the purposes of 2B350.i., the term seal refers to only those seals that come into direct contact with the chemical(s) being processed (or are designed to), and provide a sealing function where a rotary or reciprocating drive shaft passes through a pump body.
2. B. 350. j. Incinerators designed to destroy chemicals specified in ML7 or 1C350, or chemical munitions, having specially designed waste supply systems, special handling facilities and an average combustion chamber temperature greater than 1,273 K (1,000oC), in which all surfaces in the waste supply system that come into direct contact with the waste products are made from or lined with any of the following materials:
1. 'Alloys' with more than 25% nickel and 20% chromium by weight;
2. Ceramics; or
3. Nickel or 'alloys' with more than 40% nickel by weight.
2. B. 350. k. Prefabricated repair assemblies designed for items specified by 2B350.a.3. or 2B350.c.3., having all of the following, and specially designed components therefor:
1. Designed for mechanical attachment to the glass‑lining; and
2. Metallic surfaces that come in direct contact with the chemical(s) being processed which are made from tantalum or tantalum alloys.
Note: For the purposes of 2B350, the materials used for gaskets, packing, seals, screws, washers or other materials performing a sealing function do not determine the status of control, provided that such components are designed to be interchangeable.
Technical Notes:
1. For the purposes of 2B350.d., 2B350.e., 2B350.h., and 2B350.i., 'carbon graphite' is a composition consisting of amorphous carbon and graphite, in which the graphite content is eight percent or more by weight.
2. For the listed materials in the above entries, the term 'alloy' when not accompanied by a specific elemental concentration is understood as identifying those alloys where the identified metal is present in a higher percentage by weight than any other element.
2. B. 351. Toxic gas monitoring systems and their dedicated detecting components, other than those specified by 1A004, as follows, and detectors, sensor devices, and replaceable sensor cartridges therefor:
a. Designed for continuous operation and usable for the detection of chemical warfare agents or chemicals specified by 1C350, at concentrations of less than 0.3 mg/m3; or
b. Designed for the detection of cholinesterase‑inhibiting activity.
2. B. 352. Equipment capable of use in handling biological materials, as follows:
